Claim Text:
1. A method comprising: receiving a first message for a first flow from a network endpoint at a first network device; registering a relationship between the endpoint and the first network device in a directory that maps endpoints to network devices; storing a flow state for the first flow at the first network device; receiving a first message for a second flow from the network endpoint at a second network device; determining that the second network device does not store the flow state for the second flow; querying to obtain information indicative of the relationship between the first flow and the first network device in response to receiving the first message of the second flow to determine that the second network device does not store the flow state for the first flow; storing the information indicative of the relationship between the first flow and the first network device in a cache for the second network device; storing a flow state for the second flow at the second network device; registering a relationship between the endpoint and the second network device in a directory that maps endpoints to network devices; applying services to the first message for the second flow at the second network device; receiving a second message for the first flow at the second network device; and applying services to the second message of the first flow according to the stored information by forwarding the second message for the first flow to the first network device such that the services are applied to the second message for the first flow at the first network device.
