Abstract
For a network including multiple computers acting as tunnel endpoints in a network, some embodiments provide a method for distributing data messages among processors of a destination computer that receives encrypted data messages from a source computer. Each computer in some embodiments has a set of interfaces configured as tunnel endpoints connecting to multiple tunnels. The encrypted data messages are received at multiple interfaces of the destination computer and in some embodiments, include an identifier for a set of encryption parameters (e.g., a security parameter index). The encryption-parameter-set identifier is used to distribute encrypted data messages among processors of the destination computer.
