Network processor architecture for IPSec

As the Internet gets more and more complicated with the rise of new protocols and standard, the network product vendors are in need of intelligent processing at wire speed. Network processors satisfy the demand for intelligent processing at wire speed and system flexibility. IPSec is framework of open standard for ensuring private, secure communication over Internet Protocol (IP) network, through the use of cryptographic security service. This paper will give the method that embodies IPSec to IXP1200 that is network processor.
