Abstract

Fast Ethernet packages management has become a hot topic in the world since the bandwidth is approaching Gigabit and the magic speed of worm spreading. It is necessary for a server such as IDS and firewall to manage packages in an extremely fast way. In the procedure of transmitting packages, CPU copies each package twice. In order to make CPU spend less time in the copy procedure, zero-copy mechanism has been brought forward. However, in former implementations, almost all the user-face software needs to be modified and no one has made theoretical analysis of those implements. We propose SEPCOM (State basEd Partly Customizable zero cOpy Model) to speed up the package managing with the maximum compatibility. We also make a mathematic model to maximize the speed. In the end of the paper, to test our model, we propose an application to monitor network flows, which is one of the most popular applications requiring high speed of package managing.
