RFC4562 - MAC-Forced Forwarding: A Method for Subscriber Separation on an Ethernet Access Network
This document describes a mechanism to ensure layer-2 separation of Local Area Network (LAN) stations accessing an IPv4 gateway over a bridged Ethernet segment.
RFC4561 - Definition of a Record Route Object (RRO) Node-Id Sub-Object
In the context of MPLS TE Fast Reroute, the Merge Point (MP) address is required at the Point of Local Repair (PLR) in order to select a backup tunnel intersecting a fast reroutable Traffic Engineering Label Switched Path (TE LSP) on a downstream Label Switching Router (LSR). However, existing protocol mechanisms are not sufficient to find an MP address in multi-domain routing networks where a domain is defined as an Interior Gateway Protocol (IGP) area or an Autonomous System (AS). Hence, the current MPLS Fast Reroute mechanism cannot be used in order to protect inter-domain TE LSPs from a failure of an Area Border Router (ABR) or Autonomous System Border Router (ASBR). This document specifies the use of existing Record Route Object (RRO) IPv4 and IPv6 sub-objects (with a new flag defined) thus defining the node-id sub-object in order to solve this issue. The MPLS Fast Reroute mechanism mentioned in this document refers to the "Facility backup" MPLS TE Fast Reroute method. [STANDARDS-TRACK]
RFC4560 - Definitions of Managed Objects for Remote Ping, Traceroute, and Lookup Operations
This memo defines Management Information Bases (MIBs) for performing ping, traceroute, and lookup operations at a host. When managing a network, it is useful to be able to initiate and retrieve the results of ping or traceroute operations when they are performed at a remote host. A lookup capability is defined in order to enable resolution of either an IP address to an DNS name or a DNS name to an IP address at a remote host.
RFC4559 - SPNEGO-based Kerberos and NTLM HTTP Authentication in Microsoft Windows
This document describes how the Microsoft Internet Explorer (MSIE) and Internet Information Services (IIS) incorporated in Microsoft Windows 2000 use Kerberos for security enhancements of web transactions. The Hypertext Transport Protocol (HTTP) auth-scheme of "negotiate" is defined here; when the negotiation results in the selection of Kerberos, the security services of authentication and, optionally, impersonation (the IIS server assumes the windows identity of the principal that has been authenticated) are performed. This document explains how HTTP authentication utilizes the Simple and Protected GSS-API Negotiation mechanism. Details of Simple And Protected Negotiate (SPNEGO) implementation are not provided in this document. This memo provides information for the Internet community.
RFC4558 - Node-ID Based Resource Reservation Protocol (RSVP) Hello: A Clarification Statement
Use of Node-ID based Resource Reservation Protocol (RSVP) Hello messages is implied in a number of cases, e.g., when data and control planes are separated, when TE links are unnumbered. Furthermore, when link level failure detection is performed by some means other than exchanging RSVP Hello messages, use of a Node-ID based Hello session is optimal for detecting signaling adjacency failure for Resource reSerVation Protocol-Traffic Engineering (RSVP-TE). Nonetheless, this implied behavior is unclear, and this document formalizes use of the Node-ID based RSVP Hello session in some scenarios. The procedure described in this document applies to both Multi-Protocol Label Switching (MPLS) and Generalized MPLS (GMPLS) capable nodes. [STANDARDS-TRACK]
RFC4557 - Online Certificate Status Protocol (OCSP) Support for Public Key Cryptography for Initial Authentication in Kerberos (PKINIT)
This document defines a mechanism to enable in-band transmission of Online Certificate Status Protocol (OCSP) responses in the Kerberos network authentication protocol. These responses are used to verify the validity of the certificates used in Public Key Cryptography for Initial Authentication in Kerberos (PKINIT), which is the Kerberos Version 5 extension that provides for the use of public key cryptography. [STANDARDS-TRACK]
RFC4556 - Public Key Cryptography for Initial Authentication in Kerberos (PKINIT)
This document describes protocol extensions (hereafter called PKINIT) to the Kerberos protocol specification. These extensions provide a method for integrating public key cryptography into the initial authentication exchange, by using asymmetric-key signature and/or encryption algorithms in pre-authentication data fields. [STANDARDS-TRACK]
RFC4555 - IKEv2 Mobility and Multihoming Protocol (MOBIKE)
This document describes the MOBIKE protocol, a mobility and multihoming extension to Internet Key Exchange (IKEv2). MOBIKE allows the IP addresses associated with IKEv2 and tunnel mode IPsec Security Associations to change. A mobile Virtual Private Network (VPN) client could use MOBIKE to keep the connection with the VPN gateway active while moving from one address to another. Similarly, a multihomed host could use MOBIKE to move the traffic to a different interface if, for instance, the one currently being used stops working. [STANDARDS-TRACK]
RFC4554 - Use of VLANs for IPv4-IPv6 Coexistence in Enterprise Networks
Ethernet VLANs are quite commonly used in enterprise networks for the purposes of traffic segregation. This document describes how such VLANs can be readily used to deploy IPv6 networking in an enterprise, which focuses on the scenario of early deployment prior to availability of IPv6-capable switch-router equipment. In this method, IPv6 may be routed in parallel with the existing IPv4 in the enterprise and delivered at Layer 2 via VLAN technology. The IPv6 connectivity to the enterprise may or may not enter the site via the same physical link. This memo provides information for the Internet community.
RFC4553 - Structure-Agnostic Time Division Multiplexing (TDM) over Packet (SAToP)
This document describes a pseudowire encapsulation for Time Division Multiplexing (TDM) bit-streams (T1, E1, T3, E3) that disregards any structure that may be imposed on these streams, in particular the structure imposed by the standard TDM framing. [STANDARDS-TRACK]
RFC4552 - Authentication/Confidentiality for OSPFv3
This document describes means and mechanisms to provide authentication/confidentiality to OSPFv3 using an IPv6 Authentication Header/Encapsulating Security Payload (AH/ESP) extension header. [STANDARDS-TRACK]
RFC4551 - IMAP Extension for Conditional STORE Operation or Quick Flag Changes Resynchronization
Often, multiple IMAP (RFC 3501) clients need to coordinate changes to a common IMAP mailbox. Examples include different clients working on behalf of the same user, and multiple users accessing shared mailboxes. These clients need a mechanism to synchronize state changes for messages within the mailbox. They must be able to guarantee that only one client can change message state (e.g., message flags) at any time. An example of such an application is use of an IMAP mailbox as a message queue with multiple dequeueing clients.
RFC4550 - Internet Email to Support Diverse Service Environments (Lemonade) Profile
This document describes a profile (a set of required extensions, restrictions, and usage modes) of the IMAP and mail submission protocols. This profile allows clients (especially those that are constrained in memory, bandwidth, processing power, or other areas) to efficiently use IMAP and Submission to access and submit mail. This includes the ability to forward received mail without needing to download and upload the mail, to optimize submission, and to efficiently resynchronize in case of loss of connectivity with the server.
RFC4549 - Synchronization Operations for Disconnected IMAP4 Clients
This document attempts to address some of the issues involved in building a disconnected IMAP4 client. In particular, it deals with the issues of what might be called the "driver" portion of the synchronization tool: the portion of the code responsible for issuing the correct set of IMAP4 commands to synchronize the disconnected client in the way that is most likely to make the human who uses the disconnected client happy.
RFC4548 - Internet Code Point (ICP) Assignments for NSAP Addresses
This document is intended to accomplish two highly inter-related tasks: to establish an "initial" Internet Code Point (ICP) assignment for each of IPv4 and IPv6 address encoding in Network Service Access Point (NSAP) Addresses, and to recommend an IANA assignment policy for currently unassigned ICP values. In the first task, this document is a partial replacement for RFC 1888 -- particularly for section 6 of RFC 1888. In the second task, this document incorporates wording and specifications from ITU-T Recommendation X.213 and further recommends that IANA use the "IETF consensus" assignment policy in making future ICP assignments.

This MIB is defined as an extension to the DOCSIS Cable Device MIB.
RFC4546 - Radio Frequency (RF) Interface Management Information Base for Data over Cable Service Interface Specifications (DOCSIS) 2.0 Compliant RF Interfaces
This memo defines a portion of the Management Information Base (MIB) for use with network management protocols in the Internet community. In particular, it defines a set of managed objects for Simple Network Management Protocol (SNMP) based management of the Radio Frequency (RF) interfaces for systems compliant with the Data Over Cable Service Interface Specifications (DOCSIS). [STANDARDS-TRACK]
RFC4545 - Definitions of Managed Objects for IP Storage User Identity Authorization
This memo defines a portion of the Management Information Base (MIB) for use with network management protocols in TCP/IP-based internets. In particular, it defines objects for managing user identities and the names, addresses, and credentials required manage access control, for use with various protocols. This document was motivated by the need for the configuration of authorized user identities for the iSCSI protocol, but has been extended to be useful for other protocols that have similar requirements. It is important to note that this MIB module provides only the set of identities to be used within access lists; it is the responsibility of other MIB modules making use of this one to tie them to their own access lists or other authorization control methods. [STANDARDS-TRACK]
RFC4544 - Definitions of Managed Objects for Internet Small Computer System Interface (iSCSI)
This memo defines a portion of the Management Information Base (MIB) for use with network management protocols in TCP/IP-based internets. In particular, it defines objects for managing a client using the Internet Small Computer System Interface (iSCSI) protocol (SCSI over TCP). [STANDARDS-TRACK]
RFC4543 - The Use of Galois Message Authentication Code (GMAC) in IPsec ESP and AH
This memo describes the use of the Advanced Encryption Standard (AES) Galois Message Authentication Code (GMAC) as a mechanism to provide data origin authentication, but not confidentiality, within the IPsec Encapsulating Security Payload (ESP) and Authentication Header (AH). GMAC is based on the Galois/Counter Mode (GCM) of operation, and can be efficiently implemented in hardware for speeds of 10 gigabits per second and above, and is also well-suited to software implementations. [STANDARDS-TRACK]
RFC4542 - Implementing an Emergency Telecommunications Service (ETS) for Real-Time Services in the Internet Protocol Suite
RFCs 3689 and 3690 detail requirements for an Emergency Telecommunications Service (ETS), of which an Internet Emergency Preparedness Service (IEPS) would be a part. Some of these types of services require call preemption; others require call queuing or other mechanisms. IEPS requires a Call Admission Control (CAC) procedure and a Per Hop Behavior (PHB) for the data that meet the needs of this architecture. Such a CAC procedure and PHB is appropriate to any service that might use H.323 or SIP to set up real-time sessions. The key requirement is to guarantee an elevated probability of call completion to an authorized user in time of crisis.
RFC4541 - Considerations for Internet Group Management Protocol (IGMP) and Multicast Listener Discovery (MLD) Snooping Switches
This memo describes the recommendations for Internet Group Management Protocol (IGMP) and Multicast Listener Discovery (MLD) snooping switches. These are based on best current practices for IGMPv2, with further considerations for IGMPv3- and MLDv2-snooping. Additional areas of relevance, such as link layer topology changes and Ethernet-specific encapsulation issues, are also considered. This memo provides information for the Internet community.
RFC4540 - NEC's Simple Middlebox Configuration (SIMCO) Protocol Version 3.0
This document describes a protocol for controlling middleboxes such as firewalls and network address translators. It is a fully compliant implementation of the Middlebox Communications (MIDCOM) semantics described in RFC 3989. Compared to earlier experimental versions of the SIMCO protocol, this version (3.0) uses binary message encodings in order to reduce resource requirements. This memo defines an Experimental Protocol for the Internet community.
RFC4539 - Media Type Registration for the Society of Motion Picture and Television Engineers (SMPTE) Material Exchange Format (MXF)
This document serves to register a media type for the Society of Motion Picture and Television Engineers (SMPTE) Material Exchange Format (MXF).

This memo provides information for the Internet community.
RFC4538 - Request Authorization through Dialog Identification in the Session Initiation Protocol (SIP)
This specification defines the Target-Dialog header field for the Session Initiation Protocol (SIP), and the corresponding option tag, tdialog. This header field is used in requests that create SIP dialogs. It indicates to the recipient that the sender is aware of an existing dialog with the recipient, either because the sender is on the other side of that dialog, or because it has access to the dialog identifiers. The recipient can then authorize the request based on this awareness. [STANDARDS-TRACK]
RFC4537 - Kerberos Cryptosystem Negotiation Extension
This document specifies an extension to the Kerberos protocol as defined in RFC 4120, in which the client can send a list of supported encryption types in decreasing preference order, and the server then selects an encryption type that is supported by both the client and the server. [STANDARDS-TRACK]

This document specifies the media type for versions 1.0, 2.0, and 2.1 of the Synchronized Multimedia Integration Language (SMIL 1.0, SMIL 2.0, SMIL 2.1). SMIL allows integration of a set of independent multimedia objects into a synchronized multimedia presentation. This memo provides information for the Internet community.
RFC4535 - GSAKMP: Group Secure Association Key Management Protocol
This document specifies the Group Secure Association Key Management Protocol (GSAKMP). The GSAKMP provides a security framework for creating and managing cryptographic groups on a network. It provides mechanisms to disseminate group policy and authenticate users, rules to perform access control decisions during group establishment and recovery, capabilities to recover from the compromise of group members, delegation of group security functions, and capabilities to destroy the group. It also generates group keys. [STANDARDS-TRACK]
RFC4534 - Group Security Policy Token v1
The Group Security Policy Token is a structure used to specify the security policy and configurable parameters for a cryptographic group, such as a secure multicast group. Because the security of a group is composed of the totality of multiple security services, mechanisms, and attributes throughout the communications infrastructure, an authenticatable representation of the features that must be supported throughout the system is needed to ensure consistent security. This document specifies the structure of such a token. [STANDARDS-TRACK]
RFC4533 - The Lightweight Directory Access Protocol (LDAP) Content Synchronization Operation
This specification describes the Lightweight Directory Access Protocol (LDAP) Content Synchronization Operation. The operation allows a client to maintain a copy of a fragment of the Directory Information Tree (DIT). It supports both polling for changes and listening for changes. The operation is defined as an extension of the LDAP Search Operation. This memo defines an Experimental Protocol for the Internet community.
RFC4532 - Lightweight Directory Access Protocol (LDAP) "Who am I?" Operation

Directory clients may use this attribute to distinguish objects identified by a distinguished name or to locate an object after renaming. [STANDARDS-TRACK]
RFC4529 - Requesting Attributes by Object Class in the Lightweight Directory Access Protocol
The Lightweight Directory Access Protocol (LDAP) search operation provides mechanisms for clients to request all user application attributes, all operational attributes, and/or attributes selected by their description. This document extends LDAP to support a mechanism that LDAP clients may use to request the return of all attributes of an object class. This memo provides information for the Internet community.
RFC4528 - Lightweight Directory Access Protocol (LDAP) Assertion Control
This document defines the Lightweight Directory Access Protocol (LDAP) Assertion Control, which allows a client to specify that a directory operation should only be processed if an assertion applied to the target entry of the operation is true. It can be used to construct "test and set", "test and clear", and other conditional operations. [STANDARDS-TRACK]
RFC4527 - Lightweight Directory Access Protocol (LDAP) Read Entry Controls
This document specifies an extension to the Lightweight Directory Access Protocol (LDAP) to allow the client to read the target entry of an update operation. The client may request to read the entry before and/or after the modifications are applied. These reads are done as an atomic part of the update operation. [STANDARDS-TRACK]
RFC4526 - Lightweight Directory Access Protocol (LDAP) Absolute True and False Filters
This document extends the Lightweight Directory Access Protocol (LDAP) to support absolute True and False filters based upon similar capabilities found in X.500 directory systems. The document also extends the String Representation of LDAP Search Filters to support these filters. [STANDARDS-TRACK]
RFC4525 - Lightweight Directory Access Protocol (LDAP) Modify-Increment Extension
This document describes an extension to the Lightweight Directory Access Protocol (LDAP) Modify operation to support an increment capability. This extension is useful in provisioning applications, especially when combined with the assertion control and/or the pre-read or post-read control extension. This memo provides information for the Internet community.
RFC4524 - COSINE LDAP/X.500 Schema
This document provides a collection of schema elements for use with the Lightweight Directory Access Protocol (LDAP) from the COSINE and Internet X.500 pilot projects.
RFC4523 - Lightweight Directory Access Protocol (LDAP) Schema Definitions for X.509 Certificates
This document describes schema for representing X.509 certificates, X.521 security information, and related elements in directories accessible using the Lightweight Directory Access Protocol (LDAP). The LDAP definitions for these X.509 and X.521 schema elements replace those provided in RFCs 2252 and 2256. [STANDARDS-TRACK]
RFC4522 - Lightweight Directory Access Protocol (LDAP): The Binary Encoding Option
Each attribute stored in a Lightweight Directory Access Protocol (LDAP) directory has a defined syntax (i.e., data type). A syntax definition specifies how attribute values conforming to the syntax are normally represented when transferred in LDAP operations. This representation is referred to as the LDAP\-specific encoding to distinguish it from other methods of encoding attribute values. This document defines an attribute option, the binary option, that can be used to specify that the associated attribute values are instead encoded according to the Basic Encoding Rules (BER) used by X.500 directories. [STANDARDS-TRACK]
RFC4521 - Considerations for Lightweight Directory Access Protocol (LDAP) Extensions
The Lightweight Directory Access Protocol (LDAP) is extensible. It provides mechanisms for adding new operations, extending existing operations, and expanding user and system schemas. This document discusses considerations for designers of LDAP extensions. This document specifies an Internet Best Current Practices for the Internet Community, and requests discussion and suggestions for improvements.
RFC4520 - Internet Assigned Numbers Authority (IANA) Considerations for the Lightweight Directory Access Protocol (LDAP)
This document provides procedures for registering extensible elements of the Lightweight Directory Access Protocol (LDAP). The document also provides guidelines to the Internet Assigned Numbers Authority (IANA) describing conditions under which new values can be assigned. This document specifies an Internet Best Current Practices for the Internet Community, and requests discussion and suggestions for improvements.
RFC4519 - Lightweight Directory Access Protocol (LDAP): Schema for User Applications
This document is an integral part of the Lightweight Directory Access Protocol (LDAP) technical specification. It provides a technical specification of attribute types and object classes intended for use by LDAP directory clients for many directory services, such as White Pages. These objects are widely used as a basis for the schema in many LDAP directories. This document does not cover attributes used for the administration of directory servers, nor does it include directory objects defined for specific uses in other documents. [STANDARDS-TRACK]
RFC4518 - Lightweight Directory Access Protocol (LDAP): Internationalized String Preparation
The previous Lightweight Directory Access Protocol (LDAP) technical specifications did not precisely define how character string matching is to be performed. This led to a number of usability and interoperability problems. This document defines string preparation algorithms for character-based matching rules defined for use in LDAP. [STANDARDS-TRACK]
RFC4517 - Lightweight Directory Access Protocol (LDAP): Syntaxes and Matching Rules
Each attribute stored in a Lightweight Directory Access Protocol (LDAP) directory, whose values may be transferred in the LDAP protocol, has a defined syntax that constrains the structure and format of its values. The comparison semantics for values of a syntax are not part of the syntax definition but are instead provided through separately defined matching rules. Matching rules specify an argument, an assertion value, which also has a defined syntax. This document defines a base set of syntaxes and matching rules for use in defining attributes for LDAP directories. [STANDARDS-TRACK]
RFC4516 - Lightweight Directory Access Protocol (LDAP): Uniform Resource Locator
This document describes a format for a Lightweight Directory Access Protocol (LDAP) Uniform Resource Locator (URL). An LDAP URL describes an LDAP search operation that is used to retrieve information from an LDAP directory, or, in the context of an LDAP referral or reference, an LDAP URL describes a service where an LDAP operation may be progressed.
