Abstract

A method for load balancing based on metadata in a network service header. The method includes receiving a packet or frame of a traffic flow, wherein the packet or frame has a payload and the network service header including metadata and service path information for the traffic flow identifying the service path, and the metadata comprises classification information of the packet or frame, extracting, by a service header processor of the load balancer, the classification information of the metadata from the packet or frame, and applying, by a load balancing function of the load balancer, a load balancing policy on the packet or frame based on the classification information of the metadata.
