Packet Sniffer SDK is a library set for packet capture and network analysis for all Win32 platforms. The main features of the Packet Sniffer SDK library are: Any pre-installed packet drivers are not required; Support of multi-Gigabit networks; Support of all modern development environments for Windows; All PSSDK editions (VCL, DLL, and static libraries) are compiled from the same well-optimized C code. Therefore you may be assured that any Packet Sniffer SDK improvement is implemented in all its editions; Support of multiprocessor (SMP) systems; Support of packet filtering by BPF (BSD Packet Filter, user-settable packet filters) on the internal packet driver level; Supports of new FastBPF technology (Just-In-Time BPF filters compilation, works approximately 6 times faster than "classic" BPF filtering); Support of packet generation and sending functions; Support of local TCP/UDP traffic capturing with binding it to processes (including loopback traffic); Assembling of TCP sessions in data streams; High-performance traffic delivering to application and buffering it using queue Packets Pool; Support of BPF assembler for BPF filters programming; Support of disassembling BPF filters to BPF assembler source texts; All editions of Packet Sniffer SDK components/libraries contain internal packet driver, which is dynamically loaded/unloaded when the application, using Packet Sniffer SDK, is launched/closed, that allows to develop absolutely portable applications.
