Distributed Advance Network Reservation With Delay Guarantees

Free registration required

Executive Summary

New architectures have recently been proposed and deployed to support end-to-end advance reservation of network resources. These architectures rely on the use a centralized scheduler, which may be unpractical in large or administratively heterogeneous networks. In this paper, the authors explore and demonstrate the feasibility of implementing distributed solutions for advance reservation. They introduce a new distributed, distance-vector algorithm, called Distributed Advance Reservation (DAR) that provably returns the earliest time possible for setting up a connection between any two nodes.
