[routing-wg]Re: Possible IAB workshop on routing and addressing participants?

	[Sorry about the wide distribution/duplicates. Just
	 trying to reach as many of the folks who may be
	 interested as possible --dmm]

 	Folks,
  
  	The IAB is considering holding a routing and addressing
  	workshop, perhaps in the fall 2006 time frame (see the
  	draft invite below). We're in the process of collecting
  	potential participants, so please pass along any the
  	names of folks that that you think would be productive
  	participants.
  
  	Thanks,
  
  	--dmm (for the IAB)

  	Greetings,
  
  	The IAB is sponsoring a workshop on "Scalable Routing and
  	Addressing Architectures for the Internet" in order to
  	foster interchange between the operator, standards,
  	vendor, and research communities on this important
  	topic. You are being invited to participate in this
  	effort.
  
  	This workshop effort will consist of mailing list
  	discussions in advance of, and after a face to face
  	meeting.  The technical goals of this effort are outlined
  	below.  We believe these are the critical elements to
  	fostering a constructive discussion of important routing
  	and addressing technical work going forward and are
  	soliciting workshop participation to work towards those goals.
  
  	Should you decide to join us in this workshop, you will
  	be expected to attend the face to face meeting [0],
  	contribute to (and possibly present at) that meeting, as
  	well as follow and participate in the mailing list
  	discussions. 
  
  	The most important objective of the workshop is to foster
  	and encourage innovative thinking in an area where there
  	has been little fundamental change for the last twelve
  	years. As such, the primary goals of the workshop include
  	the following two items:  
  
  	(i).	Produce a concise problem statement that will
  		serve as the input to future work on this
  		topic. This problem statement will include, among
  		other things, a list of the problems with the
  		current routing and addressing architecture. 
  		These include (but are not limited to):
  
  		- The difficulty in changing provider due to
  		  PA/CIDR addressing schemes 
  
  		- The lack of effective multi-homing support
  
  		- Limited capability to protect against either
  		  the spoofing of individual host IP addresses or
  		  entire IP address blocks   
  
  		- The limited ability to secure the routing
  		  system itself, and
  
  	(ii).	Produce a prioritized list of requirements, all
  		of which must be met by a next generation routing
  		and addressing architecture. A sample list might
  		include (in no particular order):  
  
  		- Retaining the connectionless datagram model of
  		  IP routing
  
  		- Allow users (small and large) to freely switch
  		  between providers without substantial service
  		  interruption 
  
  		- Include survival of higher-layer connections
  		  and associations when connectivity to
  		  individual providers changes 
  
  		- Allow both users and ISPs to influence path
  		  selection according to traffic management and
  		  classification requirements
  
  		- Provide better support for mobility and nomadicity
  
  	        - Provide architected instrumentation facilities
  
  		- Allow at least one-to-many multicast
  
  		- Prevent source address spoofing
  
  		- Provide a rational economic basis for deployment
  
  		- Secure the routing infrastructure, including
  		  the authentication of updates and the
  		  unauthorized injection of information into the
  		  routing system  
  
  		- Define scalability requirements for a next
  		  generation routing system 
   
  		- Have architected transition mechanisms
  		  and be incrementally deployable (where possible)
  
  	During the workshop, scribes will be assigned to
  	summarize the discussion. Post-workshop, scribes will be
  	expected to participate in finalizing the workshop
  	report. All participants will be expected to review the
  	draft workshop report before publication. 
  
  	The workshop is <date, <logistics.
  
  	Please reply within the next week indicating your
  	willingness to participate in this workshop. Please
  	indicate whether (and to what extent) you'd be able to
  	participate (we'd like an explicit 'no' if you will not
  	be able to), and what you feel is your area of
  	expertise. If you can not participate, please suggest
  	potential alternatives or substitutes.  
  
  [0]	Attendees will also need to arrange and pay for their own
  	travel and accommodations.
