RFC3234 - Middleboxes: Taxonomy and Issues
This document is intended as part of an IETF discussion about "middleboxes" - defined as any intermediary box performing functions apart from normal, standard functions of an IP router on the data path between a source host and destination host. This document establishes a catalogue or taxonomy of middleboxes, cites previous and current IETF work concerning middleboxes, and attempts to identify some preliminary conclusions. It does not, however, claim to be definitive. This memo provides information for the Internet community.
RFC3233 - Defining the IETF
This document gives a more concrete definition of "the IETF" as it understood today. Many RFCs refer to "the IETF". Many important IETF documents speak of the IETF as if it were an already-defined entity. However, no IETF document correctly defines what the IETF is.

RFC3231 - Definitions of Managed Objects for Scheduling Management Operations
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 a set of managed objects that are used to schedule management operations periodically or at specified dates and times. [STANDARDS-TRACK]
RFC3230 - Instance Digests in HTTP
HTTP/1.1 defines a Content-MD5 header that allows a server to include a digest of the response body. However, this is specifically defined to cover the body of the actual message, not the contents of the full file (which might be quite different, if the response is a Content-Range, or uses a delta encoding). Also, the Content-MD5 is limited to one specific digest algorithm; other algorithms, such as SHA-1 (Secure Hash Standard), may be more appropriate in some circumstances. Finally, HTTP/1.1 provides no explicit mechanism by which a client may request a digest. This document proposes HTTP extensions that solve these problems. [STANDARDS-TRACK]
RFC3229 - Delta encoding in HTTP
This document describes how delta encoding can be supported as a compatible extension to HTTP/1.1. [STANDARDS-TRACK]

This document specifies an Internet Best Current Practices for the Internet Community, and requests discussion and suggestions for improvements.
RFC3226 - DNSSEC and IPv6 A6 aware server/resolver message size requirements
This document mandates support for EDNS0 (Extension Mechanisms for DNS) in DNS entities claiming to support either DNS Security Extensions or A6 records. This requirement is necessary because these new features increase the size of DNS messages. If EDNS0 is not supported fall back to TCP will happen, having a detrimental impact on query latency and DNS server load. This document updates RFC 2535 and RFC 2874, by adding new requirements. [STANDARDS-TRACK]
RFC3225 - Indicating Resolver Support of DNSSEC
In order to deploy DNSSEC (Domain Name System Security Extensions) operationally, DNSSEC aware servers should only perform automatic inclusion of DNSSEC RRs when there is an explicit indication that the resolver can understand those RRs. This document proposes the use of a bit in the EDNS0 header to provide that explicit indication and describes the necessary protocol changes to implement that notification. [STANDARDS-TRACK]
RFC3224 - Vendor Extensions for Service Location Protocol, Version 2
This document specifies how the features of the Service Location Protocol, Version 2 allow for vendor extensibility safely, with no possibility of collisions. The specification introduces a new SLPv2 extension: The Vendor Opaque Extension.

RFC3220 - IP Mobility Support for IPv4
This document specifies protocol enhancements that allow transparent routing of IP datagrams to mobile nodes in the Internet. Each mobile node is always identified by its home address, regardless of its current point of attachment to the Internet. While situated away from its home, a mobile node is also associated with a care-of address, which provides information about its current point of attachment to the Internet. The protocol provides for registering the care-of address with a home agent. The home agent sends datagrams destined for the mobile node through a tunnel to the care-of address. After arriving at the end of the tunnel, each datagram is then delivered to the mobile node. [STANDARDS-TRACK]
RFC3219 - Telephony Routing over IP (TRIP)
This document presents the Telephony Routing over IP (TRIP). TRIP is a policy driven inter-administrative domain protocol for advertising the reachability of telephony destinations between location servers, and for advertising attributes of the routes to those destinations. TRIP's operation is independent of any signaling protocol, hence TRIP can serve as the telephony routing protocol for any signaling protocol. [STANDARDS-TRACK]

RFC3209 - RSVP-TE: Extensions to RSVP for LSP Tunnels
This document describes the use of RSVP (Resource Reservation Protocol), including all the necessary extensions, to establish label-switched paths (LSPs) in MPLS (Multi-Protocol Label Switching). Since the flow along an LSP is completely identified by the label applied at the ingress node of the path, these paths may be treated as tunnels. A key application of LSP tunnels is traffic engineering with MPLS as specified in RFC 2702. [STANDARDS-TRACK]
RFC3208 - PGM Reliable Transport Protocol Specification
Pragmatic General Multicast (PGM) is a reliable multicast transport protocol for applications that require ordered or unordered, duplicate- free, multicast data delivery from multiple sources to multiple receivers. PGM guarantees that a receiver in the group either receives all data packets from transmissions and repairs, or is able to detect unrecoverable data packet loss. PGM is specifically intended as a workable solution for multicast applications with basic reliability requirements. Its central design goal is simplicity of operation with due regard for scalability and network efficiency. This memo defines an Experimental Protocol for the Internet community.

RFC3202 - Definitions of Managed Objects for Frame Relay Service Level Definitions
This memo defines an extension of the Management Information Base (MIB) for use with network management protocols in TCP/IP-based internets. In particular, it defines objects for managing the Frame Relay Service Level Definitions. [STANDARDS-TRACK]
RFC3201 - Definitions of Managed Objects for Circuit to Interface Translation
This memo defines an extension of the Management Information Base (MIB) for use with network management protocols in TCP/IP-based internets. In particular, it defines objects for managing the insertion of interesting Circuit Interfaces into the ifTable. This is important for circuits that must be used within other MIB modules which require an ifEntry. It allows for integrated monitoring of circuits as well as routing to circuits using unaltered, pre-existing MIB modules. [STANDARDS-TRACK]
