Although this API wasdeveloped for Unix in the early 1980s it has also been implemented on awide variety of non-Unix systems.  TCP/IP applications written using thesockets API have in the past enjoyed a high degree of portability and wewould like the same portability with IPv6 applications.  But changes arerequired to the sockets API to support IPv6 and this memo describesthese changes.  These include a new socket address structure to carryIPv6 addresses, new address conversion functions, and some new socketoptions.  These extensions are designed to provide access to the basicIPv6 features required by TCP and UDP applications, includingmulticasting, while introducing a minimum of change into the system andproviding complete compatibility for existing IPv4 applications.Additional extensions for advanced IPv6 features (raw sockets and accessto the IPv6 extension headers) are defined in another document.

Ituniquely and reversibly transforms a Unicode string into an ASCIIstring.  ASCII characters in the Unicode string are representedliterally, and non-ASCII characters are represented by ASCII charactersthat are allowed in host name labels (letters, digits, and hyphens).This document defines a general algorithm called Bootstring that allowsa string of basic code points to uniquely represent any string of codepoints drawn from a larger set.  Punycode is an instance of Bootstringthat uses particular parameter values specified by this document,appropriate for IDNA.

This profile of the stringprep protocol is usedas part of a suite of on-the-wire protocols for internationalizing theDomain Name System (DNS).  [STANDARDS TRACK]3490    Faltstrom     Mar 2003        Internationalizing Domain                                        Names in Applications (IDNA)Until now, there has been no standard method for domain names to usecharacters outside the ASCII repertoire.  This document definesinternationalized domain names (IDNs) and a mechanism calledInternationalizing Domain Names in Applications (IDNA) for handling themin a standard fashion.  IDNs use characters drawn from a largerepertoire (Unicode), but IDNA allows the non-ASCII characters to berepresented using only the ASCII characters already allowed in so-calledhost names today.  This backward-compatible representation is requiredin existing protocols like DNS, so that IDNs can be introduced with nochanges to the existing infrastructure.  IDNA is only meant forprocessing domain names, not free text.  [STANDARDS TRACK]Ginoza                       Informational                      [Page 4]

The protocol can becompressed by using Signaling Compression (SigComp).  Similarly, theSession Description Protocol (SDP) is a text-based protocol intended fordescribing multimedia sessions for the purposes of session announcement,session invitation, and other forms of multimedia session initiation.This memo defines the SIP/SDP-specific static dictionary that SigCompmay use in order to achieve higher efficiency.  The dictionary iscompression algorithm independent.  [STANDARDS TRACK]3484    Draves        Feb 2003        Default Address Selection for                                        Internet Protocol version 6                                        (IPv6)This document describes two algorithms, for source address selection andfor destination address selection.  The algorithms specify defaultbehavior for all Internet Protocol version 6 (IPv6) implementations.They do not override choices made by applications or upper-layerprotocols, nor do they preclude the development of more advancedmechanisms for address selection.  The two algorithms share a commoncontext, including an optional mechanism for allowing administrators toprovide policy that can override the default behavior.  In dual stackimplementations, the destination address selection algorithm canconsider both IPv4 and IPv6 addresses - depending on the availablesource addresses, the algorithm might prefer IPv6 addresses over IPv4addresses, or vice-versa.All IPv6 nodes, including both hosts and routers, must implement defaultaddress selection as defined in this specification.

NP changes the fundamental nature ofa dialed E.164 number from a hierarchical physical routing address to avirtual address, thereby requiring the transparent translation of thelater to the former.  In addition, there are various regulatoryconstraints that establish relevant parameters for NP implementation,most of which are not network technology specific.  Consequently, theimplementation of NP behavior consistent with applicable regulatoryconstraints, as well as the need for interoperation with the existingGSTN NP implementations, are relevant topics for numerous areas of IPtelephony works-in-progress with the IETF.

Feb 2003        Fault Tolerance for the Label                                        Distribution Protocol (LDP)Multiprotocol Label Switching (MPLS) systems will be used in corenetworks where system downtime must be kept to an absolute minimum.Many MPLS Label Switching Routers (LSRs) may, therefore, exploit FaultTolerant (FT) hardware or software to provide high availability of thecore networks.The details of how FT is achieved for the various components of an FTLSR, including Label Distribution Protocol (LDP), the switching hardwareand TCP, are implementation specific.  This document identifies issuesin the LDP specification inRFC 3036, "LDP Specification", that make itdifficult to implement an FT LSR using the current LDP protocols, anddefines enhancements to the LDP specification to ease such FT LSRimplementations.Ginoza                       Informational                      [Page 8]

[STANDARDSTRACK]3478    Leelanivas    Feb 2003        Graceful Restart Mechanism for                                        Label Distribution ProtocolThis document describes a mechanism that helps to minimize the negativeeffects on MPLS traffic caused by Label Switching Router's (LSR's)control plane restart, specifically by the restart of its LabelDistribution Protocol (LDP) component, on LSRs that are capable ofpreserving the MPLS forwarding component across the restart.The mechanism described in this document is applicable to all LSRs, boththose with the ability to preserve forwarding state during LDP restartand those without (although the latter needs to implement only a subsetof the mechanism described in this document).  Supporting (a subset of)the mechanism described here by the LSRs that can not preserve theirMPLS forwarding state across the restart would not reduce the negativeimpact on MPLS traffic caused by their control plane restart, but itwould minimize the impact if their neighbor(s) are capable of preservingthe forwarding state across the restart of their control plane andimplement the mechanism described here.The mechanism makes minimalistic assumptions on what has to be preservedacross restart - the mechanism assumes that only the actual MPLSforwarding state has to be preserved; the mechanism does not require anyof the LDP-related states to be preserved across the restart.The procedures described in this document apply to downstreamunsolicited label distribution.  Extending these procedures todownstream on demand label distribution is for further study.[STANDARDS TRACK]3477    Kompella      Jan 2003        Signalling Unnumbered Links in                                        Resource ReSerVation Protocol -                                        Traffic Engineering (RSVP-TE)Current signalling used by Multi-Protocol Label Switching TrafficEngineering (MPLS TE) does not provide support for unnumbered links.This document defines procedures and extensions to Resource ReSerVationProtocol (RSVP) for Label Switched Path (LSP) Tunnels (RSVP-TE), one ofthe MPLS TE signalling protocols, that are needed in order to supportunnumbered links.

To deliver reliableservice, MPLS requires a set of procedures to provide protection of thetraffic carried on different paths.  This requires that the labelswitching routers (LSRs) support fault detection, fault notification,and fault recovery mechanisms, and that MPLS signaling support theconfiguration of recovery.

Critical content canhelp a content gateway to decide what parts to forward.  It can indicatehow hard a gateway should try to  deliver a body part.  It can help thegateway to pick body parts that are safe to silently delete when asystem of lesser capability receives a message.  In addition, criticalcontent can help the gateway chose the notification strategy for thereceiving system.  Likewise, if the sender expects the destination to dosome processing on a body part, critical content allows the sender tomark body parts that the receiver must process.

These problems arise in several access networks,including bandwidth-asymmetric networks and packet radio subnetworks,for different underlying reasons.  However, the end result on TCPperformance is the same in both cases: performance often degradessignificantly because of imperfection and variability in the ACKfeedback from the receiver to the sender.The document details several mitigations to these effects, which haveeither been proposed or evaluated in the literature, or are currentlydeployed in networks.  These solutions use a combination of local link-layer techniques, subnetwork, and end-to-end mechanisms, consisting of:(i) techniques to manage the channel used for the upstream bottlenecklink carrying the ACKs, typically using header compression or reducingthe frequency of TCP ACKs, (ii) techniques to handle this reduced ACKfrequency to retain the TCP sender's acknowledgment-triggered self-clocking and (iii) techniques to schedule the data and ACK packets inthe reverse direction to improve performance in the presence of two-waytraffic.  Each technique is described, together with known issues, andrecommendations for use.  A summary of the recommendations is providedat the end of the document.

The original KEY RR used sub-typing to store both DNSSEC keysand arbitrary application keys.  Storing both DNSSEC and applicationkeys with the same record type is a mistake.  This document removesapplication keys from the KEY record by redefining the Protocol Octetfield in the KEY RR Data.  As a result of removing application keys, allbut one of the flags in the KEY record become unnecessary and areredefined.

PPP endpoints typically have direct access to the commonphysical media connecting them and thus have detailed knowledge aboutthe media that is in use.  When the L2TP is used, the two PPP peers areno longer directly connected over the same physical media.  Instead,L2TP inserts a virtual connection over some or all of the PPP connectionby tunneling PPP frames over a packet switched network such as IP.Under some conditions, an L2TP endpoint may need to negotiate PPP LinkControl Protocol (LCP) options at a location which may not have accessto all of the media information necessary for proper participation inthe LCP negotiation.  This document provides a mechanism forcommunicating desired LCP options between L2TP endpoints in advance ofPPP LCP negotiation at the far end of an L2TP tunnel, as well as amechanism for communicating the negotiated LCP options back to where thenative PPP link resides.

The decomposed multimedia gatewayconsists of a Call Agent, which contains the call control"intelligence", and a media gateway which contains the media functions,e.g., conversion from TDM voice to Voice over IP.Media gateways contain endpoints on which the Call Agent can create,modify and delete connections in order to establish and control mediasessions with other multimedia endpoints.  Also, the Call Agent caninstruct the endpoints to detect certain events and generate signals.The endpoints automatically communicate changes in service state to theCall Agent.  Furthermore, the Call Agent can audit endpoints as well asthe connections on endpoints.The basic and general MGCP protocol is defined in this document, howevermost media gateways will need to implement one or more MGCP packages,which define extensions to the protocol suitable for use with specifictypes of media gateways.  Such packages are defined in separatedocuments.  This memo provides information for the Internet community.Ginoza                       Informational                     [Page 25]

First, the memo motivatesperiodic sampling and addresses the question of its value as analternative to the Poisson sampling described inRFC 2330.  The benefitsinclude applicability to active and passive measurements, simulation ofconstant bit rate (CBR) traffic (typical of multimedia communication, ornearly CBR, as found with voice activity detection), and severalinstances in which analysis can be simplified.  The sampling methodavoids predictability by mandating random start times and finite lengthtests.  Following descriptions of the sampling method and sample metricparameters, measurement methods and errors are discussed.  Finally, wegive additional information on periodic measurements, including securityconsiderations.  [STANDARDS TRACK]Ginoza                       Informational                     [Page 26]

Zero-byte headercompression exists in order to prevent the single-octet ROHC header frompushing a packet voice stream into the next higher fixed packet size forthe radio.  It is usable in certain widely deployed older airinterfaces.  This document adds the zero-byte operation for ROHCBidirectional Reliable mode (R-mode) to the ones specified forUnidirectional (U-mode) and Bidirectional Optimistic (O-mode) modes ofheader compression inRFC 3242.
