Abstract:
1. A method for maintaining Session Initiation Protocol (SIP) application session affinity, the method comprising: inspecting a SIP request associated with an application session to determine a presence within the SIP request of a logical name of a destination SIP container among a plurality of SIP containers; routing the SIP request to the destination SIP container in response to the SIP request including the logical name of the destination SIP container; assigning the SIP request to a determined SIP container among the plurality of SIP containers in accordance with a predefined assignment protocol in response to an absence of the logical name of the destination SIP container in the SIP request; receiving the SIP request at the determined SIP container without the logical name of the destination SIP container and determining at the determined SIP container a related SIP application, wherein the SIP request includes a session identifier for an application session of the related SIP application managed by a session SIP container of the plurality of SIP containers; and determining at the determined SIP container the session SIP container managing the application session of the SIP request based on application of a function to a value based on the session identifier and causing the SIP request to be routed from the determined SIP container to the session SIP container in response to the application session being managed by other than the determined SIP container.
