Abstract: Techniques for defining a service flow definition among container pods that provide services in a network. The techniques may include an orchestrator of a computer network platform of the network determining which container pods need to communicate with which container pods. The service flow definition thus indicates needed paths between the container pods. In configurations, a cluster topology may be determined where the cluster topology indicates corresponding nodes of the network in which each container pod is located, as well as end points of the network with which the corresponding nodes communicate. Based at least in part on the service flow definition and the cluster topology, corresponding route distribution policies may be determined for the end points. The corresponding route distribution policies may be applied to the end points.

In one example, a first computing node may receive a multicast communication from a second computing node and register a for a flow associated with the multicast communication, wherein the context includes at least the multicast port associated with the multicast communication. The first computing node further identifies an outbound communication destined for the second computing node and determines that addressing attributes in the outbound communication match the context for the flow. Once it is determined that the attributes match the context for the flow, the first computing node associates the outbound communication with the flow.
