Packet Sniffer SDK is a development suite for network packet capture in multi-Gigabit network environment.

Packet Sniffer SDK library set is 100% exactly what you knew you wanted but never expected to get: a fully self-contained, dynamically-loaded packet capture technology that is compatible with Microsoft Visual C++, Microsoft Visual Basic .NET, Intel C++, Borland C++ Builder, Borland Delphi and many others.

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.
