Xcast6 (Explicit Multi-unicast for IPv6) is a new multicast scheme
that supports very large number of small multicast sessions. Xcast6
sends data via optimal route without traffic redundancy when Xcast-
aware routers exist; otherwise, data will be sent in daisy-chain
form. In this document, we propose Xcast6 Treemap - an extension of
Xcast6. Using Xcast6 Treemap, data can be branched not only at source
but also at remote hosts, solving the limitation of daisy-chain
connection. Xcast6 Treemap utilizes existing multicast infrastructure
(Xcast-aware routers) to improve application performance and reduce
traffic redundancy on network; also, it automatically switches to
end-host multicast operation mode in the absence of Xcast-aware
router. For widely deployment of Xcast6, routers must be upgraded
gradually. This requires a long term strategy and Xcast6 Treemap is a
good choice for incremental deployment.
