Control architecture for next generation communication network based on distributed databases
Masafumi Katoh, Koso Murakami · 2003
An intelligent routing control system that uses distributed databases is discussed. Each database manages a switching system, and the databases are connected through high-speed signalling networks that are separated from the transport network. If a requested physical address cannot be found in one database, search request messages are distributed, to all the other databases simultaneously. It is shown that for up to 100 million subscribers, this routing control system can find a physical address within one second, if each database uses ten memories with access times of 200 ns and the interdatabase link speed is 14 Mb/s.>
