BUFFERED SESSION FILTERING FOR INLINE BYPASS APPLICATION

摘要

A switch appliance includes: a first network port for communication with a first node, the first network port configured to receive a packet; a second network port for communication with a second node; a first instrument port for communication with a first inline tool; a buffer; and a processing unit coupled to the first network port, the second network port, the first instrument port, and the buffer; wherein the processing unit is configured to determine whether a packet processing state has been set as an inline-tool processing state or a bypass state; wherein the processing unit is configured to pass the packet to the second network port for transmission to the second node, and also to store a copy of the packet in the buffer, if the packet processing state has not been set as the inline-tool processing state nor the bypass state.
