Abstract

The fast evolution and increase in use of nowadays networks forces researchers to look for efficient ways of managing all the information that travels through those networks. Added to that, the growing use of Linux as main operating system for servers and big grid computing farms, has developed many research lines for increasing the networking capabilities and efficiency of the kernel code. Having that in mind, this document shows the basic internals of the networking code of Linux kernel and discusses the efficiency of the existing implementation in the 2.6 version. Besides, various tests are done for detecting existing bottlenecks in the networking core. Finally are also exposed guidelines for improving certain aspects of the kernel networking behaviour.
