Smuggling and recovery of non-packet information

摘要

One embodiment disclosed relates to a networking apparatus. The networking apparatus includes a plurality of blade subsystems and a master system communicatively coupled to the blade subsystems. A particular blade subsystem is configured to provide an additional feature in relation to processing network packets. The remaining blade subsystems are configured to send non-packet information to the one blade subsystem by replacing original information in a packet with the non-packet information. The particular blade subsystem is further configured to retrieve the non-packet information from the packet. Other embodiments are also disclosed.
