I-D ACTION:draft-ietf-opsec-routing-protocols-crypto-issues-07.txt

A New Internet-Draft is available from the on-line Internet-Drafts 
directories.
This draft is a work item of the Operational Security Capabilities for IP Network Infrastructure Working
Group of the IETF.

	Title		: Issues with existing Cryptographic Protection Methods for Routing Protocols
	Author(s)	: J. Jaeggli, S. Hares, M. Bhatia, V. Manral, R. White
	Filename	: draft-ietf-opsec-routing-protocols-crypto-issues-07.txt
	Pages		: 20
	Date		: 2010-8-31
	
Routing protocols have over time been extended to use cryptographic 
   mechanisms to validate data being received from a neighboring router 
   to ensure that:  

   o It has not been modified in transit.   
   o Actually originated from an authorized neighboring router.   

   The cryptographic mechanisms defined to date and described in this 
   document rely on a digest produced with a hash algorithm applied to 
   the payload encapsulated in the routing protocol packet.      

   This document outlines some of the limitations of the current 
   mechanism, problems with manual keying of these cryptographic 
   algorithms, and possible vectors for the exploitation of these 
   limitations.

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

	Title           : Deprecation of BGP AS_SET.
	Author(s)       : W. Kumari

	Pages           : 10
	Date            : 2010-08-31

This document deprecates the use of the AS_SET type of the AS_PATH in
BGPv4.  This is done to simply the design and implementation of the
BGP protocol and to make the semantics of the originator of a route
more clear.

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

	Title           : Virtual Subnet: A Scalable Data Center Network Architecture
	Author(s)       : X. Xu

	Pages           : 13
	Date            : 2010-08-31

This document proposes a scalable data center network architecture 
which, as an alternative to the Spanning Tree Protocol Bridge 
network, uses a Layer 3 routing infrastructure based on BGP/MPLS IP 
VPN technology [RFC4364] with some extensions, together with some 
other proven technologies including ARP proxy [RFC925][RFC1027] to 
provide scalable virtual Layer 2 network connectivity services.

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

	Title           : Datagram Transport Layer Security (DTLS) for Stream Control Transmission Protocol (SCTP)
	Author(s)       : M. Tuexen, et al.
	Filename        : draft-ietf-tsvwg-dtls-for-sctp-06.txt
	Pages           : 10
	Date            : 2010-09-01

This document describes the usage of the Datagram Transport Layer
Security (DTLS) protocol over the Stream Control Transmission
Protocol (SCTP).

DTLS over SCTP provides communications privacy for applications that
use SCTP as its transport protocol and allows client/server
applications to communicate in a way that is designed to prevent
eavesdropping and detect tampering or message forgery.

Applications using DTLS over SCTP can use almost all transport
features provided by SCTP and its extensions.

I-D Action:draft-ebalard-mext-m6t-01.txt

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

	Title           : MIPv6 from IPv4-only networks
	Author(s)       : A. Ebalard
	Filename        : draft-ebalard-mext-m6t-01.txt
	Pages           : 13
	Date            : 2010-09-01

MIPv6 [RFC3775] protocol has been designed to work on IPv6 networks:
nothing was initially provisioned in the specification to support
movement of Mobile Nodes to IPv4-only networks (with or without NAT)
or the communication with IPv4 peers.

DSMIPv6 [RFC5555] is the official solution specified to address those
needs.  It requires IPv4/NAT-awareness by the MIPv6 module, IKE
module and IPsec stack.  The global approach selected by DSMIPv6
requires changes to implementations and increases complexity.

This memo presents an alternative approach to support operations of
MIPv6 mobile nodes from IPv4-only networks.  It does not require
changes to MIPv6 modules, IKE module and IPsec stack.

I-D Action:draft-ietf-speermint-voipthreats-04.txt

A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Session PEERing for Multimedia INTerconnect Working Group of the IETF.

	Title           : SPEERMINT Security Threats and Suggested Countermeasures
	Author(s)       : J. Seedorf, et al.
	Filename        : draft-ietf-speermint-voipthreats-04.txt
	Pages           : 25
	Date            : 2010-09-01

Security requirements for SPEERMINT can be found in
draft-ietf-speermint-requirements.  This document presents different
security threats related to SPEERMINT, classifying them into threats
to the Lookup Function (LUF), to the Location Routing Function (LRF),
to the Signaling Function (SF), and to the Media Function (MF).
Various instances of the threats are briefly introduced inside the
classification.  Finally, existing security solutions for SIP and
RTP/RTCP are presented to describe countermeasures currently
available for such threats.  The objective of this document is to
identify and enumerate SPEERMINT-specific threat vectors.  Further,
the document intends to give guidance for implementers on selecting
appropriate countermeasures, and on fulfilling the SPEERMINT security
requirements specified in draft-ietf-speermint-requirements.

	Title           : Remote Authentication Dial In User Service (RADIUS) Protocol Extensions

	Date            : 2010-09-01

The Remote Authentication Dial In User Service (RADIUS) protocol is
nearing exhaustion of its current 8-bit attribute type space.  In
addition, experience shows a growing need for complex grouping, along
with attributes which can carry more than 253 octets of data.  This
document defines changes to RADIUS which address all of the above
problems.

I-D Action:draft-ietf-behave-ftp64-05.txt

A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Behavior Engineering for Hindrance Avoidance Working Group of the IETF.

	Title           : An FTP ALG for IPv6-to-IPv4 translation
	Author(s)       : I. van Beijnum
	Filename        : draft-ietf-behave-ftp64-05.txt
	Pages           : 15
	Date            : 2010-09-01

The File Transfer Protocol (FTP) has a very long history, and despite
the fact that today, other options exist to perform file transfers,
FTP is still in common use.  As such, it is important that in the
situation where some client computers are IPv6-only while many
servers are still IPv4-only and IPv6-to-IPv4 translators are used to
bridge that gap, FTP is made to work through these translators as
best it can.

FTP has an active and a passive mode, both as original commands that
are IPv4-specific, and as extended, IP version agnostic commands.
The only FTP mode that works without changes through an IPv6-to-IPv4
translator is extended passive.  However, many existing FTP servers
do not support this mode, and some clients do not ask for it.  This
document describes specifies a middlebox that may solve this
mismatch.

Second Last Call: <draft-ietf-krb-wg-anon-12.txt> (Anonymity Support for Kerberos) to Proposed Standard


The IESG has received a request from the Kerberos WG (krb-wg) to consider
the following document:
- 'Anonymity Support for Kerberos'
  <draft-ietf-krb-wg-anon-12.txt> as a Proposed Standard

This document was originally last called in 2008, but was returned to
the working group for additional work.  Based on the significant changes,
a second IETF Last Call was needed.

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 2010-09-15. 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.

This specification defines the new MODIFY method for the Real Time
Streaming Protocol (RTSP).  MODIFY method allows a RTSP client to
indicate to the RTSP server to modify a particular session.  Using
MODIFY method, a client can indicate to either transfer or share a
particular streaming session with other RTSP device.
