Abstract: An approach for improving throughput for encapsulated network traffic is provided. In an embodiment, a method comprises obtaining a plurality of network addresses of a plurality of intermediaries that facilitate communications between a plurality of virtual machines. A set of source-destination intermediary pairs is determined based on the plurality of network addresses, and for each source-destination intermediary pair, from the set of source-destination intermediary pairs, a precomputed encapsulated header is generated and included in a set of precomputed encapsulated headers. If a data packet from a particular source intermediary and destined to a particular destination intermediary is received, and a particular precomputed encapsulated header for the particular source intermediary and the particular destination intermediary is included in the set of precomputed encapsulated headers, then the particular precomputed encapsulated header is retrieved from the set of precomputed encapsulated headers and used to form a particular encapsulated packet.

Abstract: Described herein are systems, methods, and software to enhance flow operations on a host computing system. In one implementation, a virtual switch on a host identifies a packet from a virtual node. In response to identifying the packet, the virtual switch determines whether the packet corresponds to a cached result action based on traits of the packet. If the packet corresponds to a cached result action, then the virtual switch may process the packet in accordance with the cached result action. In contrast, if the packet does not correspond to a cached result action, then the virtual switch may process the packet in accordance with first flow operations to determine a result action, and cache the result action for use with future packets.
