In this paper, we present, QoSMIC, a multicast protocol for the Internet that supports QoS-sensitive routing, and minimizes the importance of <i>a priori configuration</i> decisions (such as <i>core</i> selection). The protocol is resource-efficient, robust, flexible, and scalable. In addition, our protocol is provably loop-free.Our protocol starts with a(More)
On-line multicasting has received a lot of attention lately, because of its great practical importance. However, most research assumes undirected graphs, which fail to model the directivity of real networks. In this paper, we ll this gap by ooering upper and lower bounds for the on-line directed multicast problem in a worst case analysis. We examine two(More)
We propose Delegated Tuning and Forwarding (DTF), a new architecture for dynamically assigning wavelength channels in a \broadcast star" optical network. DTF exploits tunable components without making excessive demands on tuner agility by combining the tuning on demand of receivers with the forwarding of packets over a logical topology. We describe the(More)
