Abstract
An arrangement of a network element, which routes communication traffic among different types of communication networks, includes a central processing unit configured to perform routing operations on the basis of a communication protocol, which forms a stack. Also, the arrangement of the network element includes devices configured to handle signal processing related issues and communicating with the central processing unit. The communication protocol stack is divided into a first stack situated in the central processing unit, which performs the routing operations of protocols in the first stack, and into a second stack, each device that handles signal processing related issues performing the operations of protocols in the second stack.
