Non-core based shared tree architecture for IPmulticasting
Seok‐Joo Koh, Myung Ki Shin, Jong Hwa Yi, Jin Ho Hahm, Chee H. Park · Electronics Letters · 1999
The core-based tree (CBT) has three main limitations. The selection of the core node is difficult and the traffic is concentrated near the core router. Also the CBT does not consider an optimisation of network resource utilisation. In the proposed non-core based tree (NCBT), an on-tree node is assigned to each incoming member for multicasting such that the maximum end-to-end delay and the tree costs are jointly minimised.
