Performance of NACK-oriented reliable multicast in distributed routers
Markus Hidell, P. Sjodin · 2006
We investigate a decentralized modular system design for routers, where functional modules are connected to a high-performance network. In such a distributed system internal reliable dissemination of data to multiple receivers is an important issue. We study the use of a reliable multicast protocol (NORM-NACK-oriented reliable multicast) for routing table dissemination in a distributed router, which has been designed and implemented in our networking laboratory. Experimental results of using both file-and stream-oriented transport services in NORM are presented and compared. We also compare the use of reliable multicast with an ideal "hand-tuned" multicast dissemination. We find that NORM is useful for this application, but that there is a certain cost in terms of overhead
