Compact Multicast Routing

Abstract

In a distributed network, a compact multicast scheme is a routing scheme that allows any source to send messages to any set of targets. We study the trade-off between the space used to store the routing table on each node and the stretch factor of the multicast scheme – the maximum ratio over all sets of nodes between the cost of the multicast route induced by the scheme and the cost of a steiner tree between the same set of target nodes. We obtain results in several variants of the problem: labeled -- in which the designer can choose polylogarithmic node names, name-independent – in which nodes have arbitrarily chosen names, dynamic – an online version of the problem in which nodes dynamically join and leave the multicast service and the goal is to minimize both the cost of the multicast tree at each stage and the total cost of control messages needed to update the tree.
