A DYNAMIC PROGRAMMABLE ROUTING ARCHITECTURE WITH QUALITY OF SERVICE SUPPORT

摘要

A communications network collects and present views of the network, including the networking capacity graph. The invention provides a framework and application programming interface (API) for implementing a large class of route computation algorithms without the need for any distributed communication on the part of the latter, and for providing interested software entities the ability to register to receive alerts of any changes to a view of the network. An objective of the invention is to simplify and modularize the operations of systems such as route computing engines and connection controllers, though it is not limited to these. The schedulable region of the network is distributed. Thus, remote objects desiring to do call admission control are enabled to perform independent route computation based on these views.
