1. 1 Xcast6 Treemap Islands – – Visiting Multicast Model T. Khoa Phan* Joint work with: Joanna Moulierac*, Cuong N. Tran** and Nam Thoai** * INRIA Sophia Antipolis, France ** HCMUT, Vietnam ACM CoNEXT Student Workshop 2012 December 10, 2012 - Nice, France

2. 2 Motivation Unicast – problem with bottlenecks. IP Multicast – many problems, still cannot be used on the Internet. Multicast router

3. 3 Our Approach – Xcast6 Treemap Islands (X6Ti) Xcast-aware router Normal router What is X6Ti? A hybrid model of Network Layer Multicast (NOT IP Multicast) and Peer-to-Peer. Requirements for X6Ti? X6Ti installed at end-hosts and IPv6 support (MUST). Xcast-aware router (OPTIONAL). How X6Ti works? Black box Users X6Ti packet Xcast routers Network Layer Multicast NO Xcast routers Peer-to-Peer Only care about overlay network Network NO configuration
