Abstract

A system for assisting in controlling real-time transport protocol flow through multiple networks via use of a cluster of session routers is disclosed. The system utilizes a first computer and a cluster of computers, the cluster of computers comprising at least two associated computers connected to the first computer. Each of the associated computers comprises a second processor. The second processor is configured to perform the functions of: performing an inbound screen on route information received by an associated computer, from the first computer, to determine if the received route information should be discarded; if the route information is not discarded, comparing the received and screened route information to a local policy defined within the cluster of computers; and performing an outbound screen on the received and screened information prior to transmitting the received and screened information outside the cluster of computers.
