A New Internet-Draft is available from the on-line Internet-Drafts directories.

	Title           : Linked Cache Invalidation
	Author(s)       : Mark Nottingham
                          Mike Kelly
	Filename        : draft-nottingham-linked-cache-inv-02.txt

	Date            : 2012-05-31

   This memo defines two new link types that indicate relationships
   between resources in terms of cache invalidation, along with a HTTP
   cache-control extension that takes advantage of those relationships
   to use them to extend response freshness.  Collectively, this is
   referred to as Linked Cache Invalidation (LCI).

	Title           : Prevent IP Spoofing Based On Link State Database (pisl)

   The Internet is suffering from severe DoS and DDoS attacks, and IP
   spoofing is one common used method to do DoS and DDoS attacks.  IP
   spoofing refers to that attackers send packets with forged source IP
   addresses.  In this memo, we propose one new approach of preventing
   IP spoofing, which we name PISL.  The PISL-enabled router generates
   the incoming table for source addresses using link state database,
   which exists in two most widely used intra-domain protocols:  OSPF
   and IS-IS.  In this memo, we only describe PISL in the OSPF
   environment.  The PISL-enabled router determines that a packet is
   spoofed if the packet arrives at an invalid incoming interface.  PISL
   only uses the existing information and does not impose new control
   messages, so it is easy to be deployed.  We have conducted simple
   simulation, which shows the high effectiveness of PISL:  even if PISL
   is only deployed in 10% of all OSPF routers in a network, 80%~99% of
   spoofing cases in the network can be detected.

A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item
of the Constrained RESTful Environments Working Group of the IETF.

	Title           : CoRE Link Format
	Author(s)       : Zach Shelby

	Pages           : 25
	Date            : 2012-06-01

   This specification defines Web Linking using a link format for use by
   constrained web servers to describe hosted resources, their
   attributes and other relationships between links.  Based on the HTTP
   Link Header field defined in RFC5988, the CoRE Link Format is carried
   as a payload and is assigned an Internet media type.  A well-known
   URI is defined as a default entry-point for requesting the links
   hosted by a server.

Last Call: <draft-sandlund-rfc4996bis-02.txt> (RObust Header Compression (ROHC): A Profile for TCP/IP (ROHC-TCP)) to Proposed Standard


The IESG has received a request from an individual submitter to consider
the following document:
- 'RObust Header Compression (ROHC): A Profile for TCP/IP (ROHC-TCP)'
  <draft-sandlund-rfc4996bis-02.txt> as Proposed Standard

The IESG plans to make a decision in the next few weeks, and solicits
final comments on this action. Please send substantive comments to the
ietf <at> ietf.org mailing lists by 2012-06-29. Exceptionally, comments may be
sent to iesg <at> ietf.org instead. In either case, please retain the
beginning of the Subject line to allow automated sorting.

Abstract

   This document specifies a ROHC (Robust Header Compression) profile
   for compression of TCP/IP packets.  The profile, called ROHC-TCP,
   provides efficient and robust compression of TCP headers, including
   frequently used TCP options such as SACK (Selective Acknowledgments)
   and Timestamps.

   ROHC-TCP works well when used over links with significant error rates
   and long round-trip times.  For many bandwidth-limited links where
   header compression is essential, such characteristics are common.

   This specification obsoletes [RFC4996].  It fixes a technical issue
   with the SACK compression and clarifies other compression methods
   used.

Last Call: <draft-ietf-6man-rfc3484bis-05.txt> (Default Address Selection for Internet Protocol version 6 (IPv6)) to Proposed Standard


The IESG has received a request from the IPv6 Maintenance WG (6man) to
consider the following document:
- 'Default Address Selection for Internet Protocol version 6 (IPv6)'
  <draft-ietf-6man-rfc3484bis-05.txt> as Proposed Standard

The IESG plans to make a decision in the next few weeks, and solicits
final comments on this action. Please send substantive comments to the
ietf <at> ietf.org mailing lists by 2012-06-15. Exceptionally, comments may be
sent to iesg <at> ietf.org instead. In either case, please retain the
beginning of the Subject line to allow automated sorting.

Abstract

   This document describes two algorithms, one for source address
   selection and one for destination address selection.  The algorithms
   specify default behavior for all Internet Protocol version 6 (IPv6)
   implementations.  They do not override choices made by applications
   or upper-layer protocols, nor do they preclude the development of
   more advanced mechanisms for address selection.  The two algorithms
   share a common context, including an optional mechanism for allowing
   administrators to provide policy that can override the default
   behavior.  In dual stack implementations, the destination address
   selection algorithm can consider both IPv4 and IPv6 addresses -
   depending on the available source addresses, the algorithm might
   prefer IPv6 addresses over IPv4 addresses, or vice-versa.

   Default address selection as defined in this specification applies to
   all IPv6 nodes, including both hosts and routers.  This document
   obsoletes RFC 3484.

Protocol Action: 'CoRE Link Format' to Proposed Standard (draft-ietf-core-link-format-14.txt)

The IESG has approved the following document:

Technical Summary

   To enable machine-to-machine communication using 
   REST-style protocols, a standard way to do resource 
   discovery is needed.  The present document defines a 
   link format to enable Web Linking by constrained web 
   servers for describing hosted resources, their attributes 
   and other relationships between links.  A small variation 
   of the HTTP Link Header format defined in RFC5988, the 
   CoRE Link Format is carried as a payload and is assigned 
   an Internet media type.  A well-known URI is defined as a 
   default entry-point for requesting the links to resources
   hosted by a server.

Working Group Summary

   This document represents the consensus of the CoRE WG.
   There were no significant issues of contention regarding this
