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.
