Abstract: A packet broker that performs a health-status check of a proxy server while the proxy server processes one or more proxy connections. The packet broker may attempt to exchange a heartbeat signal with the proxy server, and if unsuccessful, the proxy server is assumed to be failing. In such cases, a failover is desirable.
