  • Patent number: 11968266
    Abstract: Methods and apparatus related to the storage and/or recovery of session state information are described. A communications server, e.g., a web RTC server, supporting a communications session, stores session state information corresponding to the communications session in a client device, e.g., a user device including a web browser, participating in the communications session. Following a failure of the communications server, the client device establishes a new connection with a replacement communications server and communicates the stored session state information to the replacement communications server. In some embodiments, the session state information is communicated between a communications server and a client device in encrypted form via a secure HTTP web socket connection. In various embodiments, both the communications server and the replacement communications server include or have access to a shared encryption key.
