ABSTRACT:
Techniques for providing a bulk refresh of sessions in a network are provided. A plurality of session identifiers for sessions that were created are determined. These session identifiers may be included in a bulk refresh message. The bulk refresh message is sent to a device configured to determine if sessions associated with the plurality of session identifiers are active or inactive. The device then sends a response to the refresh requestor. The response can be used to determine which sessions are active or inactive. After the determination, actions can be taken in order to clear the hanging session. For example, the session may be torn down or a BYE message may be sent to end the session on a peer device.
