Abstract

Abstract: Most Unix systems provide a set of system calls that allow applications to interact with the network directly. These primitives are useful for example in packet capture applications, which need to grab the data flowing through the network without any further processing from the kernel. WinPcap is a newly proposed architecture that adds these functionalities to Win32 operating systems. WinPcap includes a set of innovative features (such as packet monitoring and packet injection) that are not available in previous systems. This paper presents the details of the architecture and it shows its excellent performance.
