A routing based resource registry

Abstract

A proven distributed systems technology, Link-State routing, nominally used as an IGP (Interior Gateway Protocol) in large public and enterprise networks, is fundamentally a distributed database technology. In the SIS-IS system, this capability is used to implement a distributed process registry for high availability distributed systems (e.g. elastic cloud applications). The characteristics and performance of SIS-IS are compared to an alternate architecture which derives its distributed database function from a Distributed Hash Table (DHT) database.
