  1. Extension of the MLD proxy functionality to support multiple upstream interfaces<draft-contreras-multimob-multiple-upstreams-00.txt> Luis M. Contreras Telefónica I+D Carlos J. Bernardos Universidad Carlos III de Madrid (UC3M) Atlanta, PIM WG, November 2012 1

  2. Problem statement General application: sharing of a common network access infrastructure among different multicast content providers Advantages Subscribers can get their preferred contents from different multicast content providers without network constraints and without requiring PIM routing on the access / aggregation device Redundancy Multicast Content Provider A MLD proxy Multicast Content Provider B 85th IETF, Atlanta 2

  3. Other potential benefits Specific application to PMIPv6: The support of multiple upstream interfaces on an MLD proxy has been identified as an opportunity for system optimization Advantages: Traffic routing optimization within the PMIPv6 domain Simultaneous support of remote and local multicast subscription Avoidance of multiple MLD proxy instances on MAG 85th IETF, Atlanta 3

  4. Draft Motivation Solution Complexity Handling of control messages for/from multiple upstreams Efficient handling of data traffic for/from multiple upstreams Purpose Focus on multicast distribution within PMIPv6 However general applicability can be expected Requirements identification for supporting multiple upstreams Specification of the needed MLD proxy extensions 85th IETF, Atlanta 4

  5. Scenarios of applicability for MULTIMOB Listener mobility Single MLD proxy instance on MAG Remote and local multicast subscription Dual subscription to multicast groups during handover Source mobility Support of remote and direct subscription in basic source mobility Direct communication between source and listener associated with distinct LMAs but on the same MAG Route optimization support in source mobility for remote subscribers 85th IETF, Atlanta 5
