RFC6362 - Multiple Attachments for Electronic Data Interchange - Internet Integration (EDIINT)
The Electronic Data Interchange - Internet Integration (EDIINT) AS1, AS2, and AS3 messages were designed specifically for the transport of EDI documents. Since multiple interchanges could be placed within a single EDI document, there was not a need for sending multiple EDI documents in a single message. As adoption of EDIINT grew, other uses developed aside from single EDI document transport. Some transactions required multiple attachments to be interpreted together and stored in a single message. This Informational RFC describes how multiple documents, including non-EDI payloads, can be attached and transmitted in a single EDIINT transport message. The attachments are stored within the MIME multipart/related structure. A minimal list of content-types to be supported as attachments is provided. This document is not an Internet Standards Track specification; it is published for informational purposes.
RFC6361 - PPP Transparent Interconnection of Lots of Links (TRILL) Protocol Control Protocol
The Point-to-Point Protocol (PPP) defines a Link Control Protocol (LCP) and a method for negotiating the use of multiprotocol traffic over point-to-point links. This document describes PPP support for the Transparent Interconnection of Lots of Links (TRILL) Protocol, allowing direct communication between Routing Bridges (RBridges) via PPP links.

This document concludes the For Your Information (FYI) sub-series of RFCs, established by RFC 1150 for use by the IETF User Services Area, which no longer exists. The IESG does not intend to make any further additions to this RFC sub-series, and this document provides a record of this decision. This document also obsoletes RFC 1150 and changes the status of RFC 1150 to Historic. This document is not an Internet Standards Track specification; it is published for informational purposes.
RFC6359 - Datatracker Extensions to Include IANA and RFC Editor Processing Information
This document captures the requirements for integrating IANA and RFC Editor state information into the Datatracker to provide the community with a unified tool to track the status of their document as it progresses from Internet-Draft (I-D) version -00 to RFC. Extending the Datatracker to hold document data from I-D version -00 to RFC allows for increased automation between the Datatracker, IANA, and RFC Editor, thus reducing manual labor, processing errors, and potential delay. Therefore, this document also describes the requirements to make such automation possible. This document is not an Internet Standards Track specification; it is published for informational purposes.
RFC6358 - Additional Master Secret Inputs for TLS
This document describes a mechanism for using additional master secret inputs with Transport Layer Security (TLS) and Datagram TLS (DTLS). This document defines an Experimental Protocol for the Internet community.
RFC6357 - Design Considerations for Session Initiation Protocol (SIP) Overload Control
Overload occurs in Session Initiation Protocol (SIP) networks when SIP servers have insufficient resources to handle all SIP messages they receive. Even though the SIP protocol provides a limited overload control mechanism through its 503 (Service Unavailable) response code, SIP servers are still vulnerable to overload. This document discusses models and design considerations for a SIP overload control mechanism. This document is not an Internet Standards Track specification; it is published for informational purposes.
RFC6356 - Coupled Congestion Control for Multipath Transport Protocols
Often endpoints are connected by multiple paths, but communications are usually restricted to a single path per connection. Resource usage within the network would be more efficient were it possible for these multiple paths to be used concurrently. Multipath TCP is a proposal to achieve multipath transport in TCP.
RFC6355 - Definition of the UUID-Based DHCPv6 Unique Identifier (DUID-UUID)
This document defines a new DHCPv6 Unique Identifier (DUID) type called DUID-UUID. DUID-UUIDs are derived from the already-standardized Universally Unique IDentifier (UUID) format. DUID-UUID makes it possible for devices to use UUIDs to identify themselves to DHC servers and vice versa. UUIDs are globally unique and readily available on many systems, making them convenient identifiers to leverage within DHCP. [STANDARDS-TRACK]
RFC6354 - Forward-Shifted RTP Redundancy Payload Support
This document defines a simple enhancement to support RTP sessions with forward-shifted redundant encodings, i.e., redundant data sent before the corresponding primary data. Forward-shifted redundancy can be used to conceal losses of a large number of consecutive media frames (e.g., consecutive loss of seconds or even tens of seconds of media). [STANDARDS-TRACK]
RFC6353 - Transport Layer Security (TLS) Transport Model for the Simple Network Management Protocol (SNMP)
This document describes a Transport Model for the Simple Network Management Protocol (SNMP), that uses either the Transport Layer Security protocol or the Datagram Transport Layer Security (DTLS) protocol. The TLS and DTLS protocols provide authentication and privacy services for SNMP applications. This document describes how the TLS Transport Model (TLSTM) implements the needed features of an SNMP Transport Subsystem to make this protection possible in an interoperable way.

RFC6348 - Requirements for Point-to-Multipoint Extensions to the Label Distribution Protocol
This document lists a set of functional requirements that served as input to the design of Label Distribution Protocol (LDP) extensions for setting up point-to-multipoint (P2MP) Label Switched Paths (LSP), in order to deliver point-to-multipoint applications over a Multiprotocol Label Switching (MPLS) infrastructure.
RFC6347 - Datagram Transport Layer Security Version 1.2
This document specifies version 1.2 of the Datagram Transport Layer Security (DTLS) protocol. The DTLS protocol provides communications privacy for datagram protocols. The protocol allows client/server applications to communicate in a way that is designed to prevent eavesdropping, tampering, or message forgery. The DTLS protocol is based on the Transport Layer Security (TLS) protocol and provides equivalent security guarantees. Datagram semantics of the underlying transport are preserved by the DTLS protocol. This document updates DTLS 1.0 to work with TLS version 1.2. [STANDARDS-TRACK]
RFC6346 - The Address plus Port (A+P) Approach to the IPv4 Address Shortage
We are facing the exhaustion of the IANA IPv4 free IP address pool. Unfortunately, IPv6 is not yet deployed widely enough to fully replace IPv4, and it is unrealistic to expect that this is going to change before the depletion of IPv4 addresses. Letting hosts seamlessly communicate in an IPv4 world without assigning a unique globally routable IPv4 address to each of them is a challenging problem.
RFC6345 - Protocol for Carrying Authentication for Network Access (PANA) Relay Element
This document specifies Protocol for carrying Authentication for Network Access (PANA) Relay Element functionality, which enables PANA messaging between a PANA Client (PaC) and a PANA Authentication Agent (PAA) where the two nodes cannot reach each other by means of regular IP routing. [STANDARDS-TRACK]
RFC6344 - Operating Virtual Concatenation (VCAT) and the Link Capacity Adjustment Scheme (LCAS) with Generalized Multi-Protocol Label Switching (GMPLS)
This document describes requirements for, and the use of, the Generalized Multi-Protocol Label Switching (GMPLS) control plane in support of the Virtual Concatenation (VCAT) layer 1 inverse multiplexing data plane mechanism and its companion Link Capacity Adjustment Scheme (LCAS). LCAS can be used for hitless dynamic resizing of the inverse multiplex group. These techniques apply to Optical Transport Network (OTN), Synchronous Optical Network (SONET), Synchronous Digital Hierarchy (SDH), and Plesiochronous Digital Hierarchy (PDH) signals. This document updates RFC 4606 by making modifications to the procedures for supporting virtual concatenation. [STANDARDS-TRACK]

RFC6333 - Dual-Stack Lite Broadband Deployments Following IPv4 Exhaustion
This document revisits the dual-stack model and introduces the Dual- Stack Lite technology aimed at better aligning the costs and benefits of deploying IPv6 in service provider networks. Dual-Stack Lite enables a broadband service provider to share IPv4 addresses among customers by combining two well-known technologies: IP in IP (IPv4- in-IPv6) and Network Address Translation (NAT). [STANDARDS-TRACK]
RFC6332 - Multicast Acquisition Report Block Type for RTP Control Protocol (RTCP) Extended Reports (XRs)
In most RTP-based multicast applications, the RTP source sends inter- related data. Due to this interdependency, randomly joining RTP receivers usually cannot start consuming the multicast data right after they join the session. Thus, they often experience a random acquisition delay. An RTP receiver can use one or more different approaches to achieve rapid acquisition. Yet, due to various factors, performance of the rapid acquisition methods usually varies. Furthermore, in some cases, the RTP receiver can do a simple multicast join (in other cases, it is compelled to do so). For quality reporting, monitoring, and diagnostic purposes, it is important to collect detailed information from the RTP receivers about their acquisition and presentation experiences. This document addresses this issue by defining a new report block type, called the Multicast Acquisition (MA) report block, within the framework of RTP Control Protocol (RTCP) Extended Reports (XRs) (RFC 3611). This document also defines the necessary signaling of the new MA report block type in the Session Description Protocol (SDP). [STANDARDS-TRACK]
RFC6331 - Moving DIGEST-MD5 to Historic

This document is not an Internet Standards Track specification; it is published for informational purposes.
RFC6330 - RaptorQ Forward Error Correction Scheme for Object Delivery
This document describes a Fully-Specified Forward Error Correction (FEC) scheme, corresponding to FEC Encoding ID 6, for the RaptorQ FEC code and its application to reliable delivery of data objects.
RFC6329 - IS-IS Extensions Supporting IEEE 802.1aq Shortest Path Bridging
802.1aq Shortest Path Bridging (SPB) has been standardized by the IEEE as the next step in the evolution of the various spanning tree and registration protocols. 802.1aq allows for true shortest path forwarding in a mesh Ethernet network context utilizing multiple equal cost paths. This permits it to support much larger Layer 2 topologies, with faster convergence, and vastly improved use of the mesh topology. Combined with this is single point provisioning for logical connectivity membership, which includes point-to-point, point-to-multipoint, and multipoint-to-multipoint variations. This memo documents the IS-IS changes required to support this IEEE protocol and provides some context and examples. [STANDARDS-TRACK]
RFC6328 - IANA Considerations for Network Layer Protocol Identifiers
Some protocols being developed or extended by the IETF make use of the ISO/IEC (International Organization for Standardization / International Electrotechnical Commission) Network Layer Protocol Identifier (NLPID). This document provides NLPID IANA considerations. This memo documents an Internet Best Current Practice.
RFC6327 - Routing Bridges (RBridges): Adjacency
The IETF TRILL (TRansparent Interconnection of Lots of Links) protocol provides optimal pair-wise data forwarding without configuration, safe forwarding even during periods of temporary loops, and support for multipathing of both unicast and multicast traffic. TRILL accomplishes this by using IS-IS (Intermediate System to Intermediate System) link state routing and by encapsulating traffic using a header that includes a hop count. Devices that implement TRILL are called Routing Bridges (RBridges).
RFC6326 - Transparent Interconnection of Lots of Links (TRILL) Use of IS-IS
The IETF has standardized the Transparent Interconnection of Lots of Links (TRILL) protocol, which provides transparent Layer 2 forwarding using encapsulation with a hop count and IS-IS link state routing. This document specifies the data formats and code points for the IS-IS extensions to support TRILL. [STANDARDS-TRACK]
RFC6325 - Routing Bridges (RBridges): Base Protocol Specification
Routing Bridges (RBridges) provide optimal pair-wise forwarding without configuration, safe forwarding even during periods of temporary loops, and support for multipathing of both unicast and multicast traffic. They achieve these goals using IS-IS routing and encapsulation of traffic with a header that includes a hop count.
RFC6324 - Routing Loop Attack Using IPv6 Automatic Tunnels: Problem Statement and Proposed Mitigations
This document is concerned with security vulnerabilities in IPv6-in- IPv4 automatic tunnels. These vulnerabilities allow an attacker to take advantage of inconsistencies between the IPv4 routing state and the IPv6 routing state. The attack forms a routing loop that can be abused as a vehicle for traffic amplification to facilitate denial- of-service (DoS) attacks. The first aim of this document is to inform on this attack and its root causes. The second aim is to present some possible mitigation measures. It should be noted that at the time of this writing there are no known reports of malicious attacks exploiting these vulnerabilities. Nonetheless, these vulnerabilities can be activated by accidental misconfiguration. This document is not an Internet Standards Track specification; it is published for informational purposes.
RFC6323 - Sender RTT Estimate Option for the Datagram Congestion Control Protocol (DCCP)
This document specifies an update to the round-trip time (RTT) estimation algorithm used for TFRC (TCP-Friendly Rate Control) congestion control by the Datagram Congestion Control Protocol (DCCP). It updates specifications for the CCID-3 and CCID-4 Congestion Control IDs of DCCP.
RFC6322 - Datatracker States and Annotations for the IAB, IRTF, and Independent Submission Streams

The states and annotations that are to be added to the Datatracker will be applied to Internet-Drafts as soon as any of these streams identify the Internet-Draft as a potential eventual RFC, and will continue through the lifetime of the Internet-Draft. The goal of adding this information to the Datatracker is to give the whole Internet community more information about the status of these Internet-Drafts and the streams from which they originate. This document is not an Internet Standards Track specification; it is published for informational purposes.
RFC6321 - xCal: The XML Format for iCalendar
This specification defines "xCal", an XML format for iCalendar data. [STANDARDS-TRACK]
RFC6320 - Protocol for Access Node Control Mechanism in Broadband Networks
This document describes the Access Node Control Protocol (ANCP). ANCP operates between a Network Access Server (NAS) and an Access Node (e.g., a Digital Subscriber Line Access Multiplexer (DSLAM)) in a multi-service reference architecture in order to perform operations related to Quality of Service, service, and subscribers. Use cases for ANCP are documented in RFC 5851. As well as describing the base ANCP protocol, this document specifies capabilities for Digital Subscriber Line (DSL) topology discovery, line configuration, and remote line connectivity testing. The design of ANCP allows for protocol extensions in other documents if they are needed to support other use cases and other access technologies.
RFC6319 - Issues Associated with Designating Additional Private IPv4 Address Space
When a private network or internetwork grows very large, it is sometimes not possible to address all interfaces using private IPv4 address space because there are not enough addresses. This document describes the problems faced by those networks, the available options, and the issues involved in assigning a new block of private IPv4 address space.
