Packet Sniffer SDK: Performance does matter!

Packet capture and analyzing technology

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.

Three foundations of your application performance:

• Adjustable Packets Pool: The top reason of your application zero packet loss, maps packets from application mode space to the PSSDK internal driver kernel mode space and back.
• FastBPF (32/64bit BPF JIT compiler): Allows to filter traffic 6 times faster than it may be done with classic BPF virtual machine.
• Asynchronous queues for packets receiving/sending: Allow to process traffic in real time.

Use these features of PSSDK and optimize both your application performance and resources required!

Top benefits of Packet Sniffer SDK

Packet Sniffer SDK component/library family allows you to use the full power of any modern visual or non-visual development environment for creating various packet capture network applications working with raw network adapter or loopback traffic.

Using Packet Sniffer SDK the developer does not need to create special network drivers or to learn internal implementation of the network functionalities in all Windows family operating systems - Packet Sniffer SDK allows you to focus on the main task which your application must solve.

Main Packet Sniffer SDK elements are developed as objects with properties, methods, and events that make the packet capture applications development process simpler and more flexible.

To simplify the usage of LIB and DLL Packet Sniffer SDK library implementations, special wrapper classes are created, in which functions for working with PSSDK objects are represented as class methods.

Packet Sniffer SDK editions:
DLL May be used practically with any modern IDE.
VCL May be used with Borland Delphi and/or Borland C++ Builder.
Static library for Microsoft VC compatible compilers Intended for using with modern Microsoft VC++/Intel C++ compatible compilers for creation of self-contained (single .EXE file) high-performance program modules.
Static library for Borland C compilers Intended for using with modern Borland C++ compatible compilers for creation of self-contained (single .EXE file) high-performance program modules.

The main features of the Packet Sniffer SDK

.NET wrapper for PSSDK objects
Packet Sniffer SDK package is provided with .NET wrapper for PSSDK objects source texts. This wrapper allows to integrate and use PSSDK with .NET applications with easy, and may be used in any development environment supporting .NET technology.

Support of BPF
Packet Sniffer SDK supports packet filtering by BPF (BSD Packet Filter, user-settable packet filters) at the level of the built-in packet capture driver.

Support of FastBPF
Packet Sniffer SDK supports new FastBPF technology (Just-In-Time BPF filters compilation). FastBPF works approximately 6 times faster than classic BPF filtering by BPF virtual machine.

No pre-installed packet capture drivers are required
All editions of the Packet Sniffer SDK contain internal packet capture driver, which is dynamically loaded when the application is launched. When your application is started, it loads and launches built-in packet capture driver. When your application is closed, built-in packet capture driver is unloaded. This feature of PSSDK allows to create portable applications which may be launched from removable devices without installation on the user's PC.

Support of Gigabit networks
You can create an application to capture Gigabit network traffic with zero packet loss. Certainly, your success depends on CPU, RAM, HDD subsystem performance, etc.

Support of multiprocessor (SMP) systems
Packet Sniffer SDK supports symmetric multiprocessing platforms with near linear performance dependance on additional CPU resources.

Packet generating/sending functions
This feature allows to create and send packets with any structure. It may be very useful if you're going to develop network security scanner with non-intrusive vulnerability detection capabilities, or application using its own non-standard protocol.

WinPCap to PSSDK migration module
Allows easily (in hours) migrate libpcap/WinPCap-based projects to Packet Sniffer SDK.

Capturing of TCP/UDP traffic, loopback support
With PSSDK you can capture TCP sessions and reconstruct them in TCP data streams. Also localhost TCP sessions capturing with binding them with local processes is supported.

BPF assembler and disassembler
To increase readability of your BPF programs your can write them in BPF Assembler, also you can disassemble existing BPF filters in human-readable format.

Component Function

HNPSManager initializes Packet Sniffer SDK library, serves HNAdapterConfig objects
HNAdapterConfig provides access to the network adapter configuration data
HNAdapter captures/sends packets from a network adapter
HNUserFilter creating and testing of user-defined BPF filters, examining packets with such filters
HNPacket working with IP/TCP/UDP packets
HNQueue buffering and synchronized multithreaded packets processing; the basic element of the queue is HNPacket object
HNTcpManager reconstruction of TCP sessions and data-flow processing
HNTcpSession defining of TCP session properties
HNLBAdapter capturing of the local system TCP and UDP traffic
HNLBSession defining of the properties of a TCP session between local and remote hosts
HNLBHosts defining of the addresses of two hosts connected by TCP/UDP
HNFileAdapter dumping captured traffic to a CAP file in real-time, rebroadcasting traffic from a CAP file as a traffic source.

Packet Sniffer SDK supports the following operation systems:

Windows NT 4.0, Windows 2000, Windows XP, Windows 2003, Windows Vista, Windows Longhorn, Windows 98, Windows ME, WinXP x64, Win2003 x64, Vista x64.

Network adapters supported

• Ethernet (802.3);
Token-Ring;
• FDDI;
• WAN (modem).

Packet Sniffer SDK may be used to develop:

• Hardware monitoring applications;
• Applications, which use non-standard networks protocols;
• Network traffic analyzers;
• Network activity and load balance analyzers;
• Traffic generators;
• Network security scanners;
• Network Intrusion Detection Systems, etc.
