RFC7484 - Finding the Authoritative Registration Data (RDAP) Service
This document specifies a method to find which Registration Data Access Protocol (RDAP) server is authoritative to answer queries for a requested scope, such as domain names, IP addresses, or Autonomous System numbers.
RFC7483 - JSON Responses for the Registration Data Access Protocol (RDAP)
This document describes JSON data structures representing registration information maintained by Regional Internet Registries (RIRs) and Domain Name Registries (DNRs). These data structures are used to form Registration Data Access Protocol (RDAP) query responses.
RFC7482 - Registration Data Access Protocol (RDAP) Query Format
This document describes uniform patterns to construct HTTP URLs that may be used to retrieve registration information from registries (including both Regional Internet Registries (RIRs) and Domain Name Registries (DNRs)) using "RESTful" web access patterns. These uniform patterns define the query syntax for the Registration Data Access Protocol (RDAP).
RFC7481 - Security Services for the Registration Data Access Protocol (RDAP)
The Registration Data Access Protocol (RDAP) provides "RESTful" web services to retrieve registration metadata from Domain Name and Regional Internet Registries. This document describes information security services, including access control, authentication, authorization, availability, data confidentiality, and data integrity for RDAP.
RFC7480 - HTTP Usage in the Registration Data Access Protocol (RDAP)
This document is one of a collection that together describes the Registration Data Access Protocol (RDAP). It describes how RDAP is transported using the Hypertext Transfer Protocol (HTTP). RDAP is a successor protocol to the very old WHOIS protocol. The purpose of this document is to clarify the use of standard HTTP mechanisms for this application.
RFC7479 - Using Ed25519 in SSHFP Resource Records
The Ed25519 signature algorithm has been implemented in OpenSSH. This document updates the IANA "SSHFP RR Types for public key algorithms" registry by adding an algorithm number for Ed25519.
RFC7478 - Web Real-Time Communication Use Cases and Requirements
This document describes web-based real-time communication use cases. Requirements on the browser functionality are derived from the use cases.
RFC7477 - Child-to-Parent Synchronization in DNS
This document specifies how a child zone in the DNS can publish a record to indicate to a parental agent that the parental agent may copy and process certain records from the child zone. The existence of the record and any change in its value can be monitored by a parental agent and acted on depending on local policy.
RFC7476 - Information-Centric Networking: Baseline Scenarios
This document aims at establishing a common understanding about a set of scenarios that can be used as a base for the evaluation of different information-centric networking (ICN) approaches so that they can be tested and compared against each other while showcasing their own advantages. Towards this end, we review the ICN literature and document scenarios which have been considered in previous performance evaluation studies. We discuss a variety of aspects that an ICN solution can address. This includes general aspects, such as, network efficiency, reduced complexity, increased scalability and reliability, mobility support, multicast and caching performance, real-time communication efficiency, energy consumption frugality, and disruption and delay tolerance. We detail ICN-specific aspects as well, such as information security and trust, persistence, availability, provenance, and location independence.
RFC7475 - Increasing the Number of Area Directors in an IETF Area
This document removes a limit on the number of Area Directors who manage an Area in the definition of "IETF Area". This document updates RFC 2026 (BCP 9) and RFC 2418 (BCP 25).
RFC7474 - Security Extension for OSPFv2 When Using Manual Key Management
The current OSPFv2 cryptographic authentication mechanism as defined in RFCs 2328 and 5709 is vulnerable to both inter-session and intra- session replay attacks when using manual keying. Additionally, the existing cryptographic authentication mechanism does not cover the IP header. This omission can be exploited to carry out various types of attacks.
RFC7473 - Controlling State Advertisements of Non-negotiated LDP Applications
There is no capability negotiation done for Label Distribution Protocol (LDP) applications that set up Label Switched Paths (LSPs) for IP prefixes or that signal point-to-point (P2P) Pseudowires (PWs) for Layer 2 Virtual Private Networks (L2VPNs). When an LDP session comes up, an LDP speaker may unnecessarily advertise its local state for such LDP applications even when the peer session is established for some other applications like Multipoint LDP (mLDP) or the Inter-Chassis Communication Protocol (ICCP). This document defines a solution by which an LDP speaker announces to its peer its disinterest in such non-negotiated applications, thus disabling the unnecessary advertisement of corresponding application state, which would have otherwise been advertised over the established LDP session.
RFC7472 - Internet Printing Protocol (IPP) over HTTPS Transport Binding and the 'ipps' URI Scheme
This document defines the Internet Printing Protocol (IPP) over HTTPS transport binding and the corresponding 'ipps' URI scheme, which is used to designate the access to the network location of a secure IPP print service or a network resource managed by such a service.
RFC7471 - OSPF Traffic Engineering (TE) Metric Extensions
In certain networks, such as, but not limited to, financial information networks (e.g., stock market data providers), network performance information (e.g., link propagation delay) is becoming critical to data path selection.
RFC7470 - Conveying Vendor-Specific Constraints in the Path Computation Element Communication Protocol
The Path Computation Element Communication Protocol (PCEP) is used to convey path computation requests and responses both between Path Computation Clients (PCCs) and Path Computation Elements (PCEs) and between cooperating PCEs. In PCEP, the path computation requests carry details of the constraints and objective functions that the PCC wishes the PCE to apply in its computation.
RFC7469 - Public Key Pinning Extension for HTTP
This document defines a new HTTP header that allows web host operators to instruct user agents to remember ("pin") the hosts' cryptographic identities over a period of time. During that time, user agents (UAs) will require that the host presents a certificate chain including at least one Subject Public Key Info structure whose fingerprint matches one of the pinned fingerprints for that host. By effectively reducing the number of trusted authorities who can authenticate the domain during the lifetime of the pin, pinning may reduce the incidence of man-in-the-middle attacks due to compromised Certification Authorities.
RFC7468 - Textual Encodings of PKIX, PKCS, and CMS Structures
This document describes and discusses the textual encodings of the Public-Key Infrastructure X.509 (PKIX), Public-Key Cryptography Standards (PKCS), and Cryptographic Message Syntax (CMS). The textual encodings are well-known, are implemented by several applications and libraries, and are widely deployed. This document articulates the de facto rules by which existing implementations operate and defines them so that future implementations can interoperate.
RFC7467 - URN Namespace for the North Atlantic Treaty Organization (NATO)
This document allocates a formal Uniform Resource Name (URN) namespace for assignment by the North Atlantic Treaty Organization (NATO), as specified in RFC 3406. At this time, the URN will be used primarily to uniquely identify Extensible Markup Language (XML) artefacts that provide information about NATO message text formats and service specifications as described in various NATO standards, instructions, and publications.
RFC7466 - An Optimization for the Mobile Ad Hoc Network (MANET) Neighborhood Discovery Protocol (NHDP)
The link quality mechanism of the Mobile Ad Hoc Network (MANET) Neighborhood Discovery Protocol (NHDP) enables "ignoring" some 1-hop neighbors if the measured link quality from that 1-hop neighbor is below an acceptable threshold while still retaining the corresponding link information as acquired from the HELLO message exchange. This allows immediate reinstatement of the 1-hop neighbor if the link quality later improves sufficiently.
RFC7465 - Prohibiting RC4 Cipher Suites
This document requires that Transport Layer Security (TLS) clients and servers never negotiate the use of RC4 cipher suites when they establish connections. This applies to all TLS versions. This document updates RFCs 5246, 4346, and 2246.
RFC7464 - JavaScript Object Notation (JSON) Text Sequences
This document describes the JavaScript Object Notation (JSON) text sequence format and associated media type "application/json-seq". A JSON text sequence consists of any number of JSON texts, all encoded in UTF-8, each prefixed by an ASCII Record Separator (0x1E), and each ending with an ASCII Line Feed character (0x0A).
RFC7463 - Shared Appearances of a Session Initiation Protocol (SIP) Address of Record (AOR)
This document describes the requirements and implementation of a group telephony feature commonly known as Bridged Line Appearance (BLA) or Multiple Line Appearance (MLA), or Shared Call/Line Appearance (SCA). When implemented using the Session Initiation Protocol (SIP), it is referred to as shared appearances of an Address of Record (AOR) since SIP does not have the concept of lines. This feature is commonly offered in IP Centrex services and IP Private Branch Exchange (IPBX) offerings and is likely to be implemented on SIP IP telephones and SIP feature servers used in a business environment. This feature allows several user agents (UAs) to share a common AOR, learn about calls placed and received by other UAs in the group, and pick up or join calls within the group. This document discusses use cases, lists requirements, and defines extensions to implement this feature. This specification updates RFCs 3261 and 4235.
RFC7462 - URNs for the Alert-Info Header Field of the Session Initiation Protocol (SIP)
The Session Initiation Protocol (SIP) supports the capability to provide a reference to a specific rendering to be used by the User Agent (UA) as an alerting signal (e.g., a ring tone or ringback tone) when the user is alerted. This is done using the Alert-Info header field. However, the reference (typically a URL) addresses only a specific network resource with specific rendering properties. There is currently no support for standard identifiers for describing the semantics of the alerting situation or the characteristics of the alerting signal, without being tied to a particular rendering. To overcome these limitations and support new applications, a new family of URNs for use in Alert-Info header fields (and situations with similar requirements) is defined in this specification.
RFC7461 - Energy Object Context MIB
This document defines a subset of a Management Information Base (MIB) for energy management of devices. The module addresses device identification, context information, and the energy relationships between devices.
RFC7460 - Monitoring and Control MIB for Power and Energy
This document defines a subset of the Management Information Base (MIB) for power and energy monitoring of devices.
RFC7459 - Representation of Uncertainty and Confidence in the Presence Information Data Format Location Object (PIDF-LO)
This document defines key concepts of uncertainty and confidence as they pertain to location information. Methods for the manipulation of location estimates that include uncertainty information are outlined.
RFC7458 - Extensible Authentication Protocol (EAP) Attributes for Wi-Fi Integration with the Evolved Packet Core
With Wi-Fi emerging as a crucial access network for mobile service providers, it has become important to provide functions commonly available in 3G and 4G networks in Wi-Fi access networks as well. Such functions include Access Point Name (APN) Selection, multiple Packet Data Network (PDN) connections, and seamless mobility between Wi-Fi and 3G/4G networks.
RFC7457 - Summarizing Known Attacks on Transport Layer Security (TLS) and Datagram TLS (DTLS)
Over the last few years, there have been several serious attacks on Transport Layer Security (TLS), including attacks on its most commonly used ciphers and modes of operation. This document summarizes these attacks, with the goal of motivating generic and protocol-specific recommendations on the usage of TLS and Datagram TLS (DTLS).
RFC7456 - Loss and Delay Measurement in Transparent Interconnection of Lots of Links (TRILL)
Performance Monitoring (PM) is a key aspect of Operations, Administration, and Maintenance (OAM). It allows network operators to verify the Service Level Agreement (SLA) provided to customers and to detect network anomalies. This document specifies mechanisms for Loss Measurement and Delay Measurement in Transparent Interconnection of Lots of Links (TRILL) networks.
RFC7455 - Transparent Interconnection of Lots of Links (TRILL): Fault Management
This document specifies Transparent Interconnection of Lots of Links (TRILL) Operations, Administration, and Maintenance (OAM) fault management. Methods in this document follow the CFM (Connectivity Fault Management) framework defined in IEEE 802.1 and reuse OAM tools where possible. Additional messages and TLVs are defined for TRILL-specific applications or for cases where a different set of information is required other than CFM as defined in IEEE 802.1. This document updates RFC 6325.
RFC7454 - BGP Operations and Security
The Border Gateway Protocol (BGP) is the protocol almost exclusively used in the Internet to exchange routing information between network domains. Due to this central nature, it is important to understand the security measures that can and should be deployed to prevent accidental or intentional routing disturbances.
RFC7453 - MPLS Transport Profile (MPLS-TP) Traffic Engineering (TE) Management Information Base (MIB)
This memo defines a portion of the Management Information Base (MIB) for use with network management protocols in the Internet community. In particular, it describes additional managed objects and textual conventions for tunnels, identifiers, and Label Switching Routers to support Multiprotocol Label Switching (MPLS) MIB modules for transport networks.
RFC7452 - Architectural Considerations in Smart Object Networking
The term "Internet of Things" (IoT) denotes a trend where a large number of embedded devices employ communication services offered by Internet protocols. Many of these devices, often called "smart objects", are not directly operated by humans but exist as components in buildings or vehicles, or are spread out in the environment. Following the theme "Everything that can be connected will be connected", engineers and researchers designing smart object networks need to decide how to achieve this in practice.
RFC7451 - Extension Registry for the Extensible Provisioning Protocol
The Extensible Provisioning Protocol (EPP) includes features to add functionality by extending the protocol. It does not, however, describe how those extensions are managed. This document describes a procedure for the registration and management of extensions to EPP, and it specifies a format for an IANA registry to record those extensions.
RFC7450 - Automatic Multicast Tunneling
This document describes Automatic Multicast Tunneling (AMT), a protocol for delivering multicast traffic from sources in a multicast-enabled network to receivers that lack multicast connectivity to the source network. The protocol uses UDP encapsulation and unicast replication to provide this functionality.
RFC7449 - Path Computation Element Communication Protocol (PCEP) Requirements for Wavelength Switched Optical Network (WSON) Routing and Wavelength Assignment
This memo provides application-specific requirements for the Path Computation Element Communication Protocol (PCEP) for the support of Wavelength Switched Optical Networks (WSONs). Lightpath provisioning in WSONs requires a Routing and Wavelength Assignment (RWA) process. From a path computation perspective, wavelength assignment is the process of determining which wavelength can be used on each hop of a path and forms an additional routing constraint to optical light path computation. Requirements for PCEP extensions in support of optical impairments will be addressed in a separate document.
RFC7448 - MIB Transfer from the IETF to the IEEE 802.3 WG
This document records the transfer of responsibility for the Ethernet-related MIB modules DOT3-OAM-MIB, SNMP-REPEATER-MIB, POWER-ETHERNET-MIB, DOT3-EPON-MIB, EtherLike-MIB, EFM-CU-MIB, ETHER-WIS, and MAU-MIB from the IETF to the IEEE 802.3 Working Group (WG). This document also describes the procedures associated with the transfer in a similar way to how RFC 4663 records the transfer of the IETF Bridge MIB work to the IEEE 802.1 WG.
RFC7447 - Deprecation of BGP Entropy Label Capability Attribute
The BGP Entropy Label Capability attribute is defined in RFC 6790. Regrettably, it has a bug: although RFC 6790 mandates that routers incapable of processing Entropy Labels must remove the attribute, fulfillment of this requirement cannot be guaranteed in practice. This specification deprecates the attribute. A forthcoming document will propose a replacement.
RFC7446 - Routing and Wavelength Assignment Information Model for Wavelength Switched Optical Networks
This document provides a model of information needed by the Routing and Wavelength Assignment (RWA) process in Wavelength Switched Optical Networks (WSONs). The purpose of the information described in this model is to facilitate constrained optical path computation in WSONs. This model takes into account compatibility constraints between WSON signal attributes and network elements but does not include constraints due to optical impairments. Aspects of this information that may be of use to other technologies utilizing a GMPLS control plane are discussed.
RFC7445 - Analysis of Failure Cases in IPv6 Roaming Scenarios
This document identifies a set of failure cases that may be encountered by IPv6-enabled mobile customers in roaming scenarios. The analysis reveals that the failure causes include improper configurations, incomplete functionality support in equipment, and inconsistent IPv6 deployment strategies between the home and the visited networks.
RFC7444 - Security Labels in Internet Email
This document describes a header field, SIO-Label, for use in Internet email to convey the sensitivity of the message. This header field may carry a textual representation (a display marking) and/or a structural representation (a security label) of the sensitivity of the message. This document also describes a header field, SIO-Label-History, for recording changes in the message's label.
RFC7443 - Application-Layer Protocol Negotiation (ALPN) Labels for Session Traversal Utilities for NAT (STUN) Usages
Application-Layer Protocol Negotiation (ALPN) labels for Session Traversal Utilities for NAT (STUN) usages, such as Traversal Using Relays around NAT (TURN) and NAT discovery, are defined in this document to allow an application layer to negotiate STUN usages within the Transport Layer Security (TLS) connection. ALPN protocol identifiers defined in this document apply to both TLS and Datagram Transport Layer Security (DTLS).
RFC7442 - Carrying Protocol Independent Multicast - Sparse Mode (PIM-SM) in Any-Source Multicast (ASM) Mode Trees over Multipoint LDP (mLDP)
When IP multicast trees created by Protocol Independent Multicast - Sparse Mode (PIM-SM) in Any-Source Multicast (ASM) mode need to pass through an MPLS domain, it may be desirable to map such trees to Point-to-Multipoint Label Switched Paths (P2MP LSPs). This document describes how to accomplish this in the case where such P2MP LSPs are established using Label Distribution Protocol (LDP) Extensions for P2MP and Multipoint-to-Multipoint LSPs: Multipoint LDP (mLDP).
RFC7441 - Encoding Multipoint LDP (mLDP) Forwarding Equivalence Classes (FECs) in the NLRI of BGP MCAST-VPN Routes
Many service providers offer "BGP/MPLS IP VPN" service to their customers. Existing IETF standards specify the procedures and protocols that a service provider uses in order to offer this service to customers who have IP unicast and IP multicast traffic in their VPNs. It is also desirable to be able to support customers who have MPLS multicast traffic in their VPNs. This document specifies the procedures and protocol extensions that are needed to support customers who use the Multipoint LDP (mLDP) as the control protocol for their MPLS multicast traffic. Existing standards do provide some support for customers who use mLDP, but only under a restrictive set of circumstances. This document generalizes the existing support to include all cases where the customer uses mLDP, without any restrictions. This document updates RFC 6514.
RFC7440 - TFTP Windowsize Option
The "Trivial File Transfer Protocol" (RFC 1350) is a simple, lockstep, file transfer protocol that allows a client to get or put a file onto a remote host. One of its primary uses is in the early stages of nodes booting from a Local Area Network (LAN). TFTP has been used for this application because it is very simple to implement. The employment of a lockstep scheme limits throughput when used on a LAN.
RFC7439 - Gap Analysis for Operating IPv6-Only MPLS Networks
This document reviews the Multiprotocol Label Switching (MPLS) protocol suite in the context of IPv6 and identifies gaps that must be addressed in order to allow MPLS-related protocols and applications to be used with IPv6-only networks. This document is intended to focus on gaps in the standards defining the MPLS suite, and is not intended to highlight particular vendor implementations (or lack thereof) in the context of IPv6-only MPLS functionality.
RFC7438 - Multipoint LDP (mLDP) In-Band Signaling with Wildcards
There are scenarios in which an IP multicast tree traverses an MPLS domain. In these scenarios, it can be desirable to convert the IP multicast tree "seamlessly" into an MPLS Multipoint Label Switched Path (MP-LSP) when it enters the MPLS domain, and then to convert it back to an IP multicast tree when it exits the MPLS domain. Previous documents specify procedures that allow certain kinds of IP multicast trees (either Source-Specific Multicast trees or Bidirectional Multicast trees) to be attached to an MPLS Multipoint Label Switched Path (MP-LSP). However, the previous documents do not specify procedures for attaching IP Any-Source Multicast trees to MP-LSPs, nor do they specify procedures for aggregating multiple IP multicast trees onto a single MP-LSP. This document specifies the procedures to support these functions. It does so by defining "wildcard" encodings that make it possible to specify, when setting up an MP- LSP, that a set of IP multicast trees, or a shared IP multicast tree, should be attached to that MP-LSP. Support for non-bidirectional IP Any-Source Multicast trees is subject to certain applicability restrictions that are discussed in this document. This document updates RFCs 6826 and 7246.
RFC7437 - IAB, IESG, and IAOC Selection, Confirmation, and Recall Process: Operation of the Nominating and Recall Committees
The process by which the members of the IAB and IESG, and some members of the IAOC, are selected, confirmed, and recalled is specified in this document. This document is a self-consistent, organized compilation of the process as it was known at the time of publication of RFC 3777, with various updates since that version was published.
RFC7436 - IP-Only LAN Service (IPLS)
A Virtual Private LAN Service (VPLS) is used to interconnect systems across a wide-area or metropolitan-area network, making it appear that they are on a private LAN. The systems that are interconnected may themselves be LAN switches. If, however, they are IP hosts or IP routers, certain simplifications to the operation of the VPLS are possible. We call this simplified type of VPLS an "IP-only LAN Service" (IPLS). In an IPLS, as in a VPLS, LAN interfaces are run in promiscuous mode, and frames are forwarded based on their destination Media Access Control (MAC) addresses. However, the maintenance of the MAC forwarding tables is done via signaling, rather than via the MAC address learning procedures specified in the IEEE's "Media Access Control (MAC) Bridges". This document specifies the protocol extensions and procedures for support of the IPLS service.
RFC7435 - Opportunistic Security: Some Protection Most of the Time
This document defines the concept "Opportunistic Security" in the context of communications protocols. Protocol designs based on Opportunistic Security use encryption even when authentication is not available, and use authentication when possible, thereby removing barriers to the widespread use of encryption on the Internet.
