RFC3887 - Message Tracking Query Protocol
Customers buying enterprise message systems often ask: Can I track the messages? Message tracking is the ability to find out the path that a particular message has taken through a messaging system and the current routing status of that message. This document describes the Message Tracking Query Protocol that is used in conjunction with extensions to the ESMTP protocol to provide a complete message tracking solution for the Internet. [STANDARDS-TRACK]
RFC3886 - An Extensible Message Format for Message Tracking Responses
Message Tracking is expected to be used to determine the status of undelivered e-mail upon request. Tracking is used in conjunction with Delivery Status Notifications (DSN) and Message Disposition Notifications (MDN); generally, a message tracking request will be issued only when a DSN or MDN has not been received within a reasonable timeout period.
RFC3885 - SMTP Service Extension for Message Tracking
This memo defines an extension to the SMTP service whereby a client may mark a message for future tracking. [STANDARDS-TRACK]
RFC3884 - Use of IPsec Transport Mode for Dynamic Routing
IPsec can secure the links of a multihop network to protect communication between trusted components, e.g., for a secure virtual network (VN), overlay, or virtual private network (VPN). Virtual links established by IPsec tunnel mode can conflict with routing and forwarding inside VNs because IP routing depends on references to interfaces and next-hop IP addresses. The IPsec tunnel mode specification is ambiguous on this issue, so even compliant implementations cannot be trusted to avoid conflicts. An alternative to tunnel mode uses non-IPsec IPIP encapsulation together with IPsec transport mode, which we call IIPtran. IPIP encapsulation occurs as a separate initial step, as the result of a forwarding lookup of the VN packet. IPsec transport mode processes the resulting (tunneled) IP packet with an SA determined through a security association database (SAD) match on the tunnel header. IIPtran supports dynamic routing inside the VN without changes to the current IPsec architecture. IIPtran demonstrates how to configure any compliant IPsec implementation to avoid the aforementioned conflicts. IIPtran is also compared to several alternative mechanisms for VN routing and their respective impact on IPsec, routing, policy enforcement, and interactions with the Internet Key Exchange (IKE). This memo provides information for the Internet community.
RFC3883 - Detecting Inactive Neighbors over OSPF Demand Circuits (DC)
OSPF is a link-state intra-domain routing protocol used in IP networks. OSPF behavior over demand circuits (DC) is optimized in RFC 1793 to minimize the amount of overhead traffic. A part of the OSPF demand circuit extensions is the Hello suppression mechanism. This technique allows a demand circuit to go down when no interesting traffic is going through the link. However, it also introduces a problem, where it becomes impossible to detect an OSPF-inactive neighbor over such a link. This memo introduces a new mechanism called "neighbor probing" to address the above problem. [STANDARDS-TRACK]
RFC3882 - Configuring BGP to Block Denial-of-Service Attacks
This document describes an operational technique that uses BGP communities to remotely trigger black-holing of a particular destination network to block denial-of-service attacks. Black-holing can be applied on a selection of routers rather than all BGP-speaking routers in the network. The document also describes a sinkhole tunnel technique using BGP communities and tunnels to pull traffic into a sinkhole router for analysis. This memo provides information for the Internet community.
RFC3881 - Security Audit and Access Accountability Message XML Data Definitions for Healthcare Applications
This document defines the format of data to be collected and minimum set of attributes that need to be captured for security auditing in healthcare application systems. The format is defined as an XML schema, which is intended as a reference for healthcare standards developers and application designers. It consolidates several previous documents on security auditing of healthcare data. This memo provides information for the Internet community.
RFC3880 - Call Processing Language (CPL): A Language for User Control of Internet Telephony Services
This document defines the Call Processing Language (CPL), a language to describe and control Internet telephony services. It is designed to be implementable on either network servers or user agents. It is meant to be simple, extensible, easily edited by graphical clients, and independent of operating system or signalling protocol. It is suitable for running on a server where users may not be allowed to execute arbitrary programs, as it has no variables, loops, or ability to run external programs. [STANDARDS-TRACK]
RFC3879 - Deprecating Site Local Addresses
This document describes the issues surrounding the use of IPv6 site-local unicast addresses in their original form, and formally deprecates them. This deprecation does not prevent their continued use until a replacement has been standardized and implemented. [STANDARDS-TRACK]
RFC3878 - Alarm Reporting Control Management Information Base (MIB)

RFC3877 - Alarm 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 management objects used for modelling and storing alarms. [STANDARDS-TRACK]
RFC3876 - Returning Matched Values with the Lightweight Directory Access Protocol version 3 (LDAPv3)
This document describes a control for the Lightweight Directory Access Protocol version 3 that is used to return a subset of attribute values from an entry. Specifically, only those values that match a "values return" filter. Without support for this control, a client must retrieve all of an attribute's values and search for specific values locally. [STANDARDS-TRACK]
RFC3875 - The Common Gateway Interface (CGI) Version 1.1
The Common Gateway Interface (CGI) is a simple interface for running external programs, software or gateways under an information server in a platform-independent manner. Currently, the supported information servers are HTTP servers.
RFC3874 - A 224-bit One-way Hash Function: SHA-224
This document specifies a 224-bit one-way hash function, called SHA-224. SHA-224 is based on SHA-256, but it uses a different initial value and the result is truncated to 224 bits. This memo provides information for the Internet community.
RFC3873 - Stream Control Transmission Protocol (SCTP) Management Information Base (MIB)
The Stream Control Transmission Protocol (SCTP) is a reliable transport protocol operating on top of a connectionless packet network such as IP. It is designed to transport public switched telephone network (PSTN) signaling messages over the connectionless packet network, but is capable of broader applications.
RFC3872 - Management Information Base for Telephony Routing over IP (TRIP)
This memo defines a portion of the Management Information Base (MIB) module for use with network management protocols in the Internet community. In particular, it describes a set of managed objects that are used to manage Telephony Routing over IP (TRIP) devices. [STANDARDS-TRACK]
RFC3871 - Operational Security Requirements for Large Internet Service Provider (ISP) IP Network Infrastructure
This document defines a list of operational security requirements for the infrastructure of large Internet Service Provider (ISP) IP networks (routers and switches). A framework is defined for specifying "profiles", which are collections of requirements applicable to certain network topology contexts (all, core-only, edge-only...). The goal is to provide network operators a clear, concise way of communicating their security requirements to vendors. This memo provides information for the Internet community.
RFC3870 - application/rdf+xml Media Type Registration
This document describes a media type (application/rdf+xml) for use with the Extensible Markup Language (XML) serialization of the Resource Description Framework (RDF). RDF is a language designed to support the Semantic Web, by facilitating resource description and data exchange on the Web. RDF provides common structures that can be used for interoperable data exchange and follows the World Wide Web Consortium (W3C) design principles of interoperability, evolution, and decentralization. This memo provides information for the Internet community.
RFC3869 - IAB Concerns and Recommendations Regarding Internet Research and Evolution
This document discusses IAB concerns that ongoing research is needed to further the evolution of the Internet infrastructure, and that consistent, sufficient non-commercial funding is needed to enable such research. This memo provides information for the Internet community.
RFC3868 - Signalling Connection Control Part User Adaptation Layer (SUA)
This document defines a protocol for the transport of any Signalling Connection Control Part-User signalling over IP using the Stream Control Transmission Protocol. The protocol is designed to be modular and symmetric, to allow it to work in diverse architectures, such as a Signalling Gateway to IP Signalling Endpoint architecture as well as a peer-to-peer IP Signalling Endpoint architecture. [STANDARDS-TRACK]
RFC3867 - Payment Application Programmers Interface (API) for v1.0 Internet Open Trading Protocol (IOTP)
The Internet Open Trading Protocol (IOTP) provides a data exchange format for trading purposes while integrating existing pure payment protocols seamlessly. This motivates the multiple layered system architecture which consists of at least some generic IOTP application core and multiple specific payment modules.
RFC3866 - Language Tags and Ranges in the Lightweight Directory Access Protocol (LDAP)
It is often desirable to be able to indicate the natural language associated with values held in a directory and to be able to query the directory for values which fulfill the user's language needs. This document details the use of Language Tags and Ranges in the Lightweight Directory Access Protocol (LDAP). [STANDARDS-TRACK]
RFC3865 - A No Soliciting Simple Mail Transfer Protocol (SMTP) Service Extension
This document proposes an extension to Soliciting Simple Mail Transfer Protocol (SMTP) for an electronic mail equivalent to the real-world "No Soliciting" sign. In addition to the service extension, a new message header and extensions to the existing "received" message header are described. [STANDARDS-TRACK]
RFC3864 - Registration Procedures for Message Header Fields
This specification defines registration procedures for the message header fields used by Internet mail, HTTP, Netnews and other applications. This document specifies an Internet Best Current Practices for the Internet Community, and requests discussion and suggestions for improvements.
RFC3863 - Presence Information Data Format (PIDF)
This memo specifies the Common Profile for Presence (CPP) Presence Information Data Format (PIDF) as a common presence data format for CPP-compliant Presence protocols, and also defines a new media type "application/pidf+xml" to represent the XML MIME entity for PIDF. [STANDARDS-TRACK]
RFC3862 - Common Presence and Instant Messaging (CPIM): Message Format
This memo defines the MIME content type 'Message/CPIM', a message format for protocols that conform to the Common Profile for Instant Messaging (CPIM) specification. [STANDARDS-TRACK]
RFC3861 - Address Resolution for Instant Messaging and Presence
Presence and instant messaging are defined in RFC 2778. The Common Profiles for Presence and Instant Messaging define two Universal Resource Identifier (URI) schemes: 'im' for INSTANT INBOXes and 'pres' for PRESENTITIES. This document provides guidance for locating the resources associated with URIs that employ these schemes. [STANDARDS-TRACK]
RFC3860 - Common Profile for Instant Messaging (CPIM)
At the time this document was written, numerous instant messaging protocols were in use, and little interoperability between services based on these protocols has been achieved. This specification defines common semantics and data formats for instant messaging to facilitate the creation of gateways between instant messaging services. [STANDARDS-TRACK]
RFC3859 - Common Profile for Presence (CPP)
At the time this document was written, numerous presence protocols were in use (largely as components of commercial instant messaging services), and little interoperability between services based on these protocols has been achieved. This specification defines common semantics and data formats for presence to facilitate the creation of gateways between presence services. [STANDARDS-TRACK]
RFC3858 - An Extensible Markup Language (XML) Based Format for Watcher Information
Watchers are defined as entities that request (i.e., subscribe to) information about a resource. There is fairly complex state associated with these subscriptions. The union of the state for all subscriptions to a particular resource is called the watcher information for that resource. This state is dynamic, changing as subscribers come and go. As a result, it is possible, and indeed useful, to subscribe to the watcher information for a particular resource. In order to enable this, a format is needed to describe the state of watchers on a resource. This specification describes an Extensible Markup Language (XML) document format for such state. [STANDARDS-TRACK]
RFC3857 - A Watcher Information Event Template-Package for the Session Initiation Protocol (SIP)
This document defines the watcher information template-package for the Session Initiation Protocol (SIP) event framework. Watcher information refers to the set of users subscribed to a particular resource within a particular event package. Watcher information changes dynamically as users subscribe, unsubscribe, are approved, or are rejected. A user can subscribe to this information, and therefore learn about changes to it. This event package is a template-package because it can be applied to any event package, including itself. [STANDARDS-TRACK]
RFC3856 - A Presence Event Package for the Session Initiation Protocol (SIP)
This document describes the usage of the Session Initiation Protocol (SIP) for subscriptions and notifications of presence. Presence is defined as the willingness and ability of a user to communicate with other users on the network. Historically, presence has been limited to "on-line" and "off-line" indicators; the notion of presence here is broader. Subscriptions and notifications of presence are supported by defining an event package within the general SIP event notification framework. This protocol is also compliant with the Common Presence Profile (CPP) framework. [STANDARDS-TRACK]
RFC3855 - Transporting Secure/Multipurpose Internet Mail Extensions (S/MIME) Objects in X.400
This document describes protocol options for conveying objects that have been protected using the Cryptographic Message Syntax (CMS) and Secure/Multipurpose Internet Mail Extensions (S/MIME) version 3.1 over an X.400 message transfer system. [STANDARDS-TRACK]
RFC3854 - Securing X.400 Content with Secure/Multipurpose Internet Mail Extensions (S/MIME)
This document describes a protocol for adding cryptographic signature and encryption services to X.400 content with Secure/Multipurpose Internet Mail Extensions (S/MIME). [STANDARDS-TRACK]
RFC3853 - S/MIME Advanced Encryption Standard (AES) Requirement for the Session Initiation Protocol (SIP)
RFC 3261 currently specifies 3DES as the mandatory-to-implement ciphersuite for implementations of S/MIME in the Session Initiation Protocol (SIP). This document updates the normative guidance of RFC 3261 to require the Advanced Encryption Standard (AES) for S/MIME. [STANDARDS-TRACK]
RFC3852 - Cryptographic Message Syntax (CMS)
This document describes the Cryptographic Message Syntax (CMS). This syntax is used to digitally sign, digest, authenticate, or encrypt arbitrary message content. [STANDARDS-TRACK]
RFC3851 - Secure/Multipurpose Internet Mail Extensions (S/MIME) Version 3.1 Message Specification
This document defines Secure/Multipurpose Internet Mail Extensions (S/MIME) version 3.1. S/MIME provides a consistent way to send and receive secure MIME data. Digital signatures provide authentication, message integrity, and non-repudiation with proof of origin. Encryption provides data confidentiality. Compression can be used to reduce data size. This document obsoletes RFC 2633. [STANDARDS-TRACK]
RFC3850 - Secure/Multipurpose Internet Mail Extensions (S/MIME) Version 3.1 Certificate Handling
This document specifies conventions for X.509 certificate usage by Secure/Multipurpose Internet Mail Extensions (S/MIME) agents. S/MIME provides a method to send and receive secure MIME messages, and certificates are an integral part of S/MIME agent processing. S/MIME agents validate certificates as described in RFC 3280, the Internet X.509 Public Key Infrastructure Certificate and CRL Profile. S/MIME agents must meet the certificate processing requirements in this document as well as those in RFC 3280. [STANDARDS-TRACK]
RFC3849 - IPv6 Address Prefix Reserved for Documentation
To reduce the likelihood of conflict and confusion when relating documented examples to deployed systems, an IPv6 unicast address prefix is reserved for use in examples in RFCs, books, documentation, and the like. Since site-local and link-local unicast addresses have special meaning in IPv6, these addresses cannot be used in many example situations. The document describes the use of the IPv6 address prefix 2001:DB8::/32 as a reserved prefix for use in documentation. This memo provides information for the Internet community.
RFC3848 - ESMTP and LMTP Transmission Types Registration
This registers seven new mail transmission types (ESMTPA, ESMTPS, ESMTPSA, LMTP, LMTPA, LMTPS, LMTPSA) for use in the "with" clause of a Received header in an Internet message. [STANDARDS-TRACK]
RFC3847 - Restart Signaling for Intermediate System to Intermediate System (IS-IS)
This document describes a mechanism for a restarting router to signal to its neighbors that it is restarting, allowing them to reestablish their adjacencies without cycling through the down state, while still correctly initiating database synchronization. This document additionally describes a mechanism for a restarting router to determine when it has achieved LSP database synchronization with its neighbors and a mechanism to optimize LSP database synchronization, while minimizing transient routing disruption when a router starts. This memo provides information for the Internet community.
RFC3846 - Mobile IPv4 Extension for Carrying Network Access Identifiers
When a mobile node moves between two foreign networks, it has to be re-authenticated. If the home network has both multiple Authentication Authorization and Accounting (AAA) servers and Home Agents (HAs) in use, the Home AAA server may not have sufficient information to process the re-authentication correctly (i.e., to ensure that the same HA continues to be used). This document defines a Mobile IP extension that carries identities for the Home AAA and HA servers in the form of Network Access Identifiers (NAIs). The extension allows a Home Agent to pass its identity (and that of the Home AAA server) to the mobile node, which can then pass it on to the local AAA server when changing its point of attachment. This extension may also be used in other situations requiring communication of a NAI between Mobile IP nodes. [STANDARDS-TRACK]
RFC3845 - DNS Security (DNSSEC) NextSECure (NSEC) RDATA Format
This document redefines the wire format of the "Type Bit Map" field in the DNS NextSECure (NSEC) resource record RDATA format to cover the full resource record (RR) type space. [STANDARDS-TRACK]
RFC3844 - IETF Problem Resolution Process
This Informational document records the history of discussions in the Problem WG during 2003 of how to resolve the problems described in the IETF Problem Statement. It decomposes each of the problems described into a few areas for improvement and categorizes them as either problems affecting the routine processes used to create standards or problems affecting the fundamental structure and practices of the IETF. Expeditious and non-disruptive solutions are proposed for the problems affecting routine processes. The document also lists suggested ways to handle the development of solutions for the structure and practices problems proposed in IETF discussions. Neither the working group nor the wider IETF has reached consensus on a recommendation for any of the proposals. This document therefore has no alternative but to suggest that the search for structure and practices solutions be handed back to the control of the IESG. While there was working group consensus on the processes for short-term and medium term improvements, there was no working group consensus on the proposals for longer-term improvements. This document therefore includes longer-term improvement proposals only as a matter of record; they must not be regarded as recommendations from the working group. This memo provides information for the Internet community.
RFC3843 - RObust Header Compression (ROHC): A Compression Profile for IP
The original RObust Header Compression (ROHC) RFC (RFC 3095) defines a framework for header compression, along with compression protocols (profiles) for IP/UDP/RTP, IP/ESP (Encapsulating Security Payload), IP/UDP, and also a profile for uncompressed packet streams. However, no profile was defined for compression of IP only, which has been identified as a missing piece in RFC 3095. This document defines a ROHC compression profile for IP, similar to the IP/UDP profile defined by RFC 3095, but simplified to exclude UDP, and enhanced to compress IP header chains of arbitrary length. [STANDARDS-TRACK]
RFC3842 - A Message Summary and Message Waiting Indication Event Package for the Session Initiation Protocol (SIP)
This document describes a Session Initiation Protocol (SIP) event package to carry message waiting status and message summaries from a messaging system to an interested User Agent. [STANDARDS-TRACK]
RFC3841 - Caller Preferences for the Session Initiation Protocol (SIP)
This document describes a set of extensions to the Session Initiation Protocol (SIP) which allow a caller to express preferences about request handling in servers. These preferences include the ability to select which Uniform Resource Identifiers (URI) a request gets routed to, and to specify certain request handling directives in proxies and redirect servers. It does so by defining three new request header fields, Accept-Contact, Reject-Contact, and Request-Disposition, which specify the caller's preferences. [STANDARDS-TRACK]
RFC3840 - Indicating User Agent Capabilities in the Session Initiation Protocol (SIP)
This specification defines mechanisms by which a Session Initiation Protocol (SIP) user agent can convey its capabilities and characteristics to other user agents and to the registrar for its domain. This information is conveyed as parameters of the Contact header field. [STANDARDS-TRACK]
RFC3839 - MIME Type Registrations for 3rd Generation Partnership Project (3GPP) Multimedia files
This document serves to register and document the standard MIME types associated with the 3GPP multimedia file format, which is part of the family based on the ISO Media File Format. [STANDARDS-TRACK]
RFC3838 - Policy, Authorization, and Enforcement Requirements of the Open Pluggable Edge Services (OPES)
This document describes policy, authorization, and enforcement requirements for the selection of the services to be applied to a given Open Pluggable Edge Services (OPES) flow. This memo provides information for the Internet community.
