Communication traffic processing architectures and methods are disclosed. Processing load on main Central Processing Units (CPUs) can be alleviated by offloading data processing tasks to separate hardware. In one implementation, a processing architecture includes a main processor configured to execute a first portion of a driver software to perform protocol control and management task associated with control or management packets in a packet-based protocol according to which packets are received from a device, an offload processor configured to execute a second portion of the driver software to perform data processing task for data packets received according to the packet-based protocol, an interface to enable communication with the device, and an interconnect coupled to the main processor, to the offload subsystem, and to the interface.

A method of operation of a network communication system includes: analyzing a packet header by: loading a packet input register, generating a forwarding hash from the packet input register, and identifying a routing update by comparing the forwarding hash; accessing a packet analysis bus for updating the packet header; and enabling a routing switch for forwarding a packet including the packet header updated.

High-speed networking application equipments with a layer-2 to layer-7 hardware search engine and method are with flexibility and performance improvement. The multi-layer switches/routers, network address translation (NAT) gateway, firewall/VPN router and network attached storage (NAS) may use the search engine for fast and efficient search requirement.
