Abstract

For better performance and to avoid member service annoyance that results due to joining-clients' waiting durations and time-outs when there are more than one clients wanting to join concurrently for FTTH-based Broadcasting Mini-system's service, this paper proposes a more efficient and better performing Overlay Tree Building Control Protocol by modifying and extending the basic mechanisms building the conventional TBCP. The modified-TBCP (mTBCP) proposed is performance-effective mechanism since it considers the case of how fast will children, concurrently, find and join new parents when paths to existing parents are broken. Besides utilizing partial topology information, mTBCP also does a LAN-out-degree-check. If the selected child-parent-pair falls under the same LAN, that selected parent does not change the out-degree status. The performance comparison, in terms of Overlay-Connection-Count and Latency against Group-Size-Growth, between the proposed mTBCP and the traditional TBCP is done through simulations and the results conclude in favour of the proposed mTBCP.
