IP Multicast – RFC 1112,1458, 2236… Recap – • “You put packets in at one end, and the network conspires to deliver them to anyone who asks” [Dave Clark] or • When unicast is door to door, multicast is a radio station with receivers tuning into the right frequency • Every IP datagram whose destination address starts with “1110” is a multicast datagram • Remaining (28) bits identify the multicast “group” – To receive multicast message, join a group • Multicast is handled at the transport layer (OSI layer 4) with UDP – TCP provides point-to-point, thus not feasible for multicast • Default TimeToLive (TTL) of 1 which restricts datagrams to the local subnet, 255 means no restriction at all © 2009 by Markus Alexander Kuppe, Scott Lewis; made available under the EPL v1.0 | March 23, 2009
Service Locator Protocol (SLPv2) RFC 2608, … •Multicast discovery • Multicast group 239.255.255.253 • administratively scoped multicast (RFC 2365) • Port 427 (privileged port!) •User agent (UA) • maps to Locator •Service agent (SA) • maps to Advertiser •Directory agent (DA) • Optionally deployed • jSLP 2.0 • OpenSLP •Seamless transition from • Multicast convergence to • Directory Agent (DA) or hard coded • DA discovery still multicast © 2009 by Markus Alexander Kuppe, Scott Lewis; made available under the EPL v1.0 | March 23, 2009
