Editor's Note: Minutes received 11/23/92 CURRENT_MEETING_REPORT_ Reported by Paul Tsuchiya/Bellcore Minutes of P. Internet Protocol Working Group (PIP) The PIP Working Group was Chaired by Paul Tsuchiya. Except for an announcement by Paul that an implementation of PIP is planned, the whole PIP Working Group meeting was spent covering technical issues. There were many aspects of PIP that were not covered, due to lack of time. It was felt that there should be two sessions devoted to PIP at the next IETF meeting. Several decisions were made concerning header structure, and these will be reflected in the next version of the PIP header. It was decided that the segmentation function should be moved from the ``router options'' to the ``host options'', thus making it a purely end-to-end function. Therefore, routers will not be able to segment, only hosts. If a packet is too large for a particular subnet, then the router will send the host an ICMP-type message. Some concerns were raised during the meeting. In particular, Joel Halpern pointed out that the RC and HD reformatting required large amounts of memory in the case where both 1) a PIP system had a large number of neighbors, and 2) the RC or HD had a large number of significant bits. Ross Callon raised the concern that PIP might not be able to emulate the NSAP feature of encoding a subnetwork address in the internetwork layer for the purpose of easily binding the internet address to the subnet address. Paul Tsuchiya suggested a couple of ways that this could be accomplished in PIP.
