Writing software for a network processor involves implementing inter-process communication and resource management functions at a level of complexity found in distributed computing applications. So, ...

Application-specific ICs, like these from IDT, take the processing burden from a central network processor. However, compute-intensive packet searches that serve such purposes as routing, security, ...

In the last issue we started following a packet's journey from the wire up to the higher levels of network stack processing. We left the packet at the end of layer 3 processing, where IP has ...

Network geeks among you may remember my article, “Linux Socket Filter: Sniffing Bytes over the Network”, in the June 2001 issue of LJ, regarding the use of the packet filter built inside the Linux ...
