System and method for active standby policy based routing in a network

A method (190) for performing ingress/egress active-standby-spare routing in a network, the method comprising:

• receiving, a Service Communication Proxy (SCP) controller (112), a plurality of requests to be transmitted to the first and the second PLMN clusters from one or mode source node devices in communication with the SCP controller (112), wherein the SCP controller (112) is in communication with a plurality of endpoints, wherein the plurality of endpoints are grouped in either a first PLMN cluster or a second PLMN cluster such that an n number endpoint of the first PLMN cluster forms a pair with an n+2 number endpoint of the second PLMN cluster, wherein n is any natural number, and wherein the SCP controller (112) further comprises one or more processors (404) coupled to a memory (410) storing instructions executable by the one or more processors (404);
• determining, by the SCP controller (112), status of a plurality of paired n number endpoint and n+2 number end point associated with the first and the second PLMN clusters respectively;
• and
• routing, by the SCP controller (112), the plurality of requests equally through the first PLMN cluster for transmitting to each said paired n number endpoint and the n+2 number endpoint associated with the first PLMN cluster and the second PLMN cluster respectively, when the status of each said paired n number endpoint and the n+2 number endpoint is determined to be active,
• wherein the plurality of requests is routed equally to each paired n number endpoint and the n+2 number endpoint associated with the first PLMN cluster and the second PLMN cluster respectively based on a round robin technique.

A non-transitory computer readable medium comprising processor-executable instructions causing a processor to:

• receive, from one or more source node devices in communication with the processor, a plurality of requests to be transmitted to a first public land mobile network (PLMN) and a second PLMN cluster,
• wherein the processor is in communication with a plurality of endpoints, wherein the plurality of endpoints are grouped in either the first PLMN cluster or the second PLMN cluster such that an n number endpoint of the first PLMN cluster forms a pair with corresponding n+2 number endpoint of the second PLMN cluster, and wherein n is any natural number;
• determine a status of a plurality of paired n number endpoint and n+2 number endpoint associated with the first and the second PLMN clusters, respectively;
• and
• route the plurality of requests equally through the first PLMN cluster for transmitting to each said paired n number endpoint and the n+2 number endpoint associated with the first PLMN cluster and the second PLMN cluster, when the status of each said paired n number endpoint and the n+2 number endpoint is determined to be active,
• wherein the plurality of requests is routed equally to the paired n number endpoint and the n+2 number endpoint associated with the first PLMN cluster and the second PLMN cluster, respectively, based on a round robin technique.
