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.
