ION WG Minutes Internetworking over Non-broadcast Multiple Access Networks (ION) met Wednesday, December 10th, from 9:00 to 11:30. The meeting was chaired by Andy Malis and George Swallow. There were 157 in attendance. Administrative: The ION list has moved. The new host is Sun Microsystems. The mailing list information is now: General Discussion: ion@sunroof.eng.sun.com To Subscribe: majordomo@sunroof.eng.sun.com In Body: subscribe ion Archive: http://netlab.ucs.indiana.edu/hypermail/ion/ Status and Work Plan Andy Malis presented the status of new RFCs and all ION drafts. This lead into a discussion of the current work plan. The discussion resulted in an updated work plan. For the minutes are captured the status of all documents which have passed Working Group last call, followed by the updated work plan.

Submit Guidelines for Next Hop Client (NHC) Developers (will require some implementation experience) Proxy PAR (this is a fairly new effort and will require some progress prior to picking a completion date). The only other open issue is Router to Router NHRP. Joel Halpern will try to identify someone to push it forward Presentations ITU-T Study Group 11 liaison, Muneyoshi Suzuki Acting as a liaison from ITU-T, M. Suzuki presented his draft, "The Assignment of the Information Field and Protocol Identifier in the Q.2941 Generic Identifier and Q.2957 User-to-user Signaling for the Internet Protocol". Study Group 11 has been extending the BISDN signalling capabilities in ways which they hope will be of benefit to IP protocols. The purpose of this presentation was to apprise the working group of their efforts and to share their specification. Their document specifies the assignment of the information field and protocol identifier in the Q.2941 Generic Identifier and Q.2957 User-to-user Signaling for the Internet protocol. SG11 has set a goal of Q3 98 to identify internet services which don't need further signalling enhancements, and Q1 99 for those that do. A large portion of the code space has been set aside for administration by IANA. All members of the WG are encouraged to read the draft and consider how it may be employeed. The Chairs thanked Mr. Suzuki and the SG 11 for providing this mechanism and sharing it with the ION WG. Updates to the OSPF Address Resolution Advertisement and Intra- area IP Unicast drafts, Juha Heinanen Rob Coltun updated the group on the above drafts. Most of the technical updates pertain to OSPF, so this presentation was largely informational. Rob has added some sub-community capabilities to the opaque LSA. George Swallow & Rob discussed using cached OSPF metric information to determine when it is safe to continue to use an SVC indicated by an old route while an SVC to support a new (better) route is being established. Updates to the ion security drafts, Grenville Armitage draft-armitage-ion-sec-arp-00.txt draft-armitage-ion-security-01.txt These were introduced in order to call them to the working groups attention. They will be updated prior to the March meeting. Working group members are encouraged to read and comment. Updates to the IPv6 over NBMA and ATM drafts, Grenville Armitage draft-ietf-ion-ipv6-00.txt draft-ietf-ion-ipv6-atm-00.txt The primary technical change to this document is that the IPv6 Flow label is used to adjudicate shortcut attempts. Only flows with a flow label of zero are candidates for short cuts. This will be presented to the IPNG WG. The results will be discussed on the mail list. IPv6 over Frame Relay and IPv6 Inverse Neighbor Discovery drafts Alex Conta draft-conta-ion-ipv6-fr-00.txt draft-conta-ion-ipv6-ind-00.txt These drafts define the operation of IPv6 over Frame Relay. They define an IPv6 Inverse Neighbor Discovery (IND) protocol which is analogous to the inverse arp used for IPv4. The protocol allows a Frame Relay node to discover dynamically the DLCI associated with one of its virtual circuits at the remote node and an IPv6 address of that remote node. The Frame Relay interface token is constructed from the EUI bits (set to 00 to indicate local and unicast), a 38 bit MID for uniqueness, and 24 bits which contain the DLCI, zero filled. All 1s in the DLCI field indicates unspecified. The drafts will be re-issued as WG drafts with the expectation that they can be forwarded ot the IESG in advance of our next meeting. Proxy PAR for ATM router autoconfiguration, Tony Przygienda Proxy PAR (PNNI Augmented Routing) is an extension to PNNI being developed at the ATM Forum. It is designed to provide an autoconfiguration capability. This is accomplished by allowing routers to inject some information into PNNI. PNNI distributes this information through it's linkstate machinery. It is then passed up to other routers. This allows the discovery of other routers and their capabilities. The current draft offers an overview of Proxy PAR and was presented to motivate defining the use of PAR within the ION WG. This was accepted as a work group item. No completion date has been specified, except that it is expected prior to 12/98.
