Abstract
A method and non-transitory computer-readable medium are disclosed for extending a hold timer that binds an application-layer session when a transport-layer out-of-order message queue includes an out-of-order message for the application-layer session. An application receives an application-layer message from transport protocol logic that is configured to deliver in-order application-layer messages to the application. The received application-layer message is a next in-order application-layer message for an application-layer session that is bound by a hold timer. After an amount time has passed, the application detects an expiration of the hold timer. In response, rather than immediately tearing down the application-layer session, the application inspects an out-of-order queue of the transport protocol logic. The hold timer is extended when the out-of-order queue includes an out-of-order application-layer message for the application-layer session. In one aspect, the transport protocol logic includes an application programming interface that provides the application with access to the out-of-order queue.
