Host Group Extensions for CLNP Multicasting

Abstract

This memo documents work performed in the TUBA (TCP/UDP over Bigger Addresses) working group of IPng area prior to the July 1994 decision to utilize SIPP-16 as the basis for IPng. The TUBA group worked on extending the Internet Protocol suite by the use of ISO 8473 (CLNP) and its related routing protocols. This memo describes multicast extensions to CLNP and its related routing protocols for Internet multicast use. Publication of this memo does not imply acceptance by any IETF Working Group for the ideas expressed within.This memo provides a specification for multicast extensions to the CLNP protocol similar to those provided to IP by RFC1112. These extensions are intended to provide the mechanisms needed by a host for multicasting in a CLNP based Internet. This memo covers addressing extensions to the CLNP addressing structure, extensions to the CLNP protocol and extensions to the ES-IS protocol. An appendix discusses the differences between IP multicast and the CLNP multicast approach provided in this memo. AcknowledgmentsThe specification provided here was developed by a number of individuals in the IETF TUBA working group as well as the ANSI X3S3.3 and ISO SC6 WG2 committees. Key contributions were made

Jitter Considerations in Mobile Ad Hoc Networks (MANETs)

“…A possible solution to these problems is to employ jitter, a deliberate random variation in timing. Such jitter is employed in e.g., [2], [3], and [4], in which transmission intervals for regularly scheduled messages are reduced by a small, bounded and random amount in order to desynchronize transmitters and thereby avoid overloading the transmission medium as well as receivers. This document discusses and provides recommendations for applying jitter to control packet transmissions in Mobile Ad hoc NETworks (MANETs), with the purpose of avoiding collisions, with particular reference to the features listed above.…”
