1. A computing system for processing network traffic, comprising:
a plurality of network ports configured to receive network traffic; a plurality of processing blades, not directly coupled with the plurality of network ports, configured to process the network traffic; a switch coupled with the plurality of processing blades and configured to support inter-blade communications among the plurality of processing blades; and a content-aware router coupled with the switch and the plurality of network ports, the content-aware router configured to:
determine whether the received network traffic matches at least one network traffic rule;if the received network traffic does not match the at least one network traffic rule,
forward the received networking traffic to one of the plurality of processing blades based on at least one of a load and a utilization of the processing blades; andif the received network traffic matches the at least one network traffic rule,
classify and tag the received network traffic based on the content information of the plurality of processing blades,determine processing blade types based on the at least one network traffic rule,determine one of the plurality of processing blades based on the determined processing blade types and on at least one of a load and a utilization of the processing blades, andforward the received network traffic, to the determined one of the plurality of processing blades without going through another of the plurality of processing blades.
