Techniques for reducing session set-up for real-time communications over a network

摘要

Techniques for reducing session set up for real-time communications over a network include determining whether conditions are satisfied for storing session data for a first actual or prospective session and receiving the session data to be stored. The session data indicates multiple properties for real-time communications between a local node and a remote end node connected to a network. If these conditions are satisfied, then the session data is stored. If it is determined that a second session is to be established between the local node and the remote end node, then multiple properties of the second session are determined based on the stored session data. The second session is established using the stored session data instead of at least some negotiations. These techniques reduce the perceived delay from start of setup to commencement of real-time communications, or reduce the resources consumed by the end nodes and network, or both.
