Packet Sniffer SDK (former Network Investigation Suite) is the most powerful development suite for network packet capture in Windows OS family environment.The main features of the Packet Sniffer SDK library are:Any pre-installed packet drivers are not required; Support of 1GBit networks; Support of all modern development environments for Windows; All PSSDK editions (ActiveX, 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 mechanism; Support of BPF assembler for BPF filters programming; Support of disassembling BPF filters to BPF assembler source texts.All editions of the Packet Sniffer SDK components/libraries contain internal packet driver, which is dynamically loaded/unloaded when the application, using Packet Sniffer SDK, is launched/closed.
