Abstract
A network node in a service function chaining system receives multiple media streams of a media session between endpoints. Each media stream is encapsulated with a service header indicating a service function path and a session identifier. The network node determines that multiple service functions connected to the network node perform a particular service function in the service function path. The network node provides all of the media streams of the media session to a single service function instance to ensure that the media session is processed by the single service function.
