Abstract: Example methods and systems for multicast packet handling based on flow cache information are described. In one example, a network element may configure flow cache information associated with a multicast flow. The flow cache information may specify a set of actions that is configured based on a sequence of function calls. In response to detecting a multicast packet associated with the multicast flow, fast-path processing may be performed based on the flow cache information. This may include executing a replication action to generate a first packet replica and a second packet replica. First processing action(s) may be executed to process the first packet replica to generate and send a first output packet towards a first multicast destination. Second processing action(s) may be executed to process the second packet replica to generate and send a first output packet towards a second multicast destination.

Abstract: Some embodiments of the invention provide a system for implementing multiple logical routers. The system includes a Kubernetes cluster that includes multiple nodes, with each node executing a set of pods. The set of pods include a first pod for performing a first set of data message processing operations for the multiple logical routers and at least one respective separate pod for each respective logical router of the multiple logical routers. Each respective pod is for performing a respective second set of data message processing operations for the respective logical router.

Abstract: Some embodiments of the invention provide a method for implementing an edge device that handles data traffic between a logical network and an external network. The method monitors resource usage of a node pool that includes multiple nodes that each executes a respective set of pods. Each of the pods is for performing a respective set of data message processing operations for at least one of multiple logical routers. The method determines that a particular node in the node pool has insufficient resources for the particular node's respective set of pods to adequately perform their respective sets of data message processing operations. Based on the determination, the method automatically provides additional resources to the node pool by instantiating at least one additional node in the node pool.
