* * * * * * * * Notes: 1. See L. Wei and D. Estrin, “A Comparison of multicast trees and algorithms,” TR USC-CD-93-560, Dept. Computer Science, University of California, Sept 1993 for a comparison of heuristic approaches. 3.3 Network Layer: Multicast Routing Algorithms 3-16 * Notes: 1. It’s always nice to see a PhD dissertation with impact. The earliest discussion of center-based trees for multicast appears to be D. Wall, “Mechanisms for Broadcast and Selective Broadcast,” PhD dissertation, Stanford U., June 1980. 3.3 Network Layer: Multicast Routing Algorithms 3-17 * Notes: 3.3 Network Layer: Multicast Routing Algorithms 3-18 * Notes: D. Waitzman, S. Deering, C. Partridge, “Distance Vector Multicast Routing Protocol,” RFC 1075, Nov. 1988. The version of DVMRP in use today is considerably enhanced over the RFC1075 spec. A more up-to-date “work-in-progress” defines a version 3 of DVMRP: T. Pusateri, “Distance Vector Multicast Routing Protocol,” work-in-progress, draft-ietf-idmr-v3-05.ps 3.4 Network Layer: Internet Multicast Routing Algorithms 3-20 * Notes: 1. See /mbone/routers.html for a (slightly outdatet) list of multicast capable routers (supporting DVMPR as well as other protocols) from various vendors. 2. /pub/net-research/ipmulti for circa 1996 public copy “mrouted” v3.8 of DVMRP routing software for various workstation routing platforms. 3.4 Network Layer: Internet Multicast Routing Algorithms 3-21 * Notes: For a general discussion of IP encapsulation, see C. Perkins, “IP Encapsulation within IP,” RFC 2003, Oct. 1996. The book S. Bradner, A Mankin, “Ipng: Internet protocol next generation,” Addison Wesley, 1995 has a very nice discussion of tunneling Tunneling c
