In an embodiment, a method comprises establishing a first data communications session with a first router. In response to receiving a first request to establish a second data communications session, a probe message that is configured to test whether the first data communications session or the first router is responsive is sent to the first router. In response to determining that the first router has not acknowledged the probe message before a probe timer has expired, and receiving a second request to establish the second data communications session, the second data communications session with the first router is established and a state for the first data communications session is deleted. |
