Abstract: Methods and systems for analyzing flows of communication packets. A front-end processor associates input packets with flows and forwards each flow to the appropriate unit, typically by querying a flow table that holds a respective classification for each active flow. In general, flows that are not yet classified are forwarded to the classification unit, and the resulting classification is entered in the flow table. Flows that are classified as requested for further analysis are forwarded to an appropriate flow analysis unit. Flows that are classified as not requested for analysis are not subjected to further processing, e.g., discarded or allowed to pass.

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. Rather than implementing a “hard” failover, in which no further communication packets are directed to the proxy server, a “soft” failover is performed where the packet broker prevents new proxy connections from being processed by the proxy server, but maintains at least one (e.g., all) of the current proxy connections that are being processed by the proxy server.
