US Patent 10237187 System and method for service chain load balancing

The present disclosure is directed towards systems and methods of service chain load balancing. A controller intermediary to a client and computing infrastructure identifies a plurality of service chains. Each of the plurality of service chains include a path having an instance of a first service provided by the computing infrastructure and an instance of a second service provided by the computing infrastructure. The controller determines a path weight for each of the plurality of service chains. The path weight indicates a level of efficiency of delivering services in accordance with the service chain. The controller selects, based on a load balancing function and the path weight for each of the plurality of service chains, a service chain from the plurality of service chains to direct network traffic from a client.
