Sigtran user adaptation proxy load balancer
First Claim
1. A method of operating a switched circuit telephone network comprising:
- coupling a telephone switch to a signaling gateway across a first network;
coupling the signaling gateway to a plurality of application server processes across a second network, and wherein the signaling gateway sends signaling messages to the application server processes across the second network; and
coupling a load balancer between the signaling gateway and the application server processes, the load balancer adapted to distribute the signaling messages from the signaling gateway to the plurality of application server processes.

Abstract
In a switched circuit telephone network implementing an SS7 protocol with out-of-band signaling for call establishment, the specification discloses a proxy load balancer coupled between a signaling gateway and application server processes running application services. The proxy load balancer receives signaling messages from the signaling gateway directed to an application server process running an application service, and forwards that signaling message to one of two or more application server processes, each running the application service. In this way, additional application server processes may be installed in the system without reconfiguration or even knowledge of the signaling gateway. The proxy load balancer appears as a single application server process running an application service to the signaling gateway, and correspondingly appears as a signaling gateway to the two or more application server processes running application services downstream of the proxy load balancer.
