Distributed Database Management In A Highly Reliable Distributed Communications Network

摘要

Signaling information for the AT&T Com,,unications telephone network is sent through a nationwide packet switching network. Routing for some services on the telephone network is controlled by a distributed database that is accessed through the packet switching network. Operations on the distributed database are limited to read-only transactions and to administrative updates of the database. These conditions allow the application of an efficient update algorithm that does not delay the large volume of read-only transactions.
