LCM: a multicast core management protocol for link-state routing networks

We propose solutions to several multicast core management problems, including automatic core selection, core failure handling, and core migration, for use in networks based on link-state routing. The proposed approach uses a central server, called the core binding server (CBS), to manage core-group bindings, accompanied by a network-level leader election protocol in order to achieve robustness. By modeling the selection of the CBS as a leader election problem, this approach can handle any combination of network component failures, including those that partition the network. Further, our simulation results reveal that the central server can sustain extremely high workloads, and demonstrate the effectiveness of our core selection and core migration methods.
