Windows Network Driver bRAWcap for
high-performance recording and replay on 10 GbE interfaces

Windows Netzwerktreiber bRAWcap

With our Windows LWF driver bRAWcap we create a tool for high-performance recording and replay on 10G Ethernet interfaces. The tapping of data packets is highly effective and lossless. bRAWcap is optimized to enable high-performance sending and receiving of high data rates with minimal use of CPU resources. Get the most out of your existing Windows software and the associated software packages and save yourself the trouble of moving to a different operating system.

Why choose bRAWcap?

Key Features

No more CPU overload

 

With our Windows LWF driver, we create a tool for high-performance recording on 10G Ethernet interfaces. The tapping of data packets is highly effective and loss-free. bRAWcap is optimized to enable fast sending and receiving of high data rates with a minimum use of CPU resources.

Minimal use of CPU resources
Seamless integration and easy operation
Benefit from seamless integration and easy use

 

With bRAWcap, you get a centralized way to access the Ethernet interfaces that are assigned to it. This feature provides seamless integration and operation of your software without having to interfere with the operating system (OS) to retrieve the desired information. In summary, bRAWcap allows you to easily upgrade receive and transmit performance and raw Ethernet communications to OSI layer 2 in your existing Windows software and associated applications.

Get deep insight into raw data

 

Unlike other drivers, bRAWcap already operates on OSI layer 2. This allows insight down to Ethernet level and into the optional VLAN tags (IEEE 802.1Q). To enable a temporal correlation of the packets, the existing RX/TX time stamps are made accessible for each packet. Especially for recordings and analysis this data is essential. With standard Windows drivers, the collection of raw data is not possible.

Deep insight into raw data
User-defined filters
Only see data that is relevant to you

 

The powerful solution for Ethernet data transmission offers a wide range of functions that allow you to customize the transmission of data to your individual needs. With bRAWcap, you can easily filter packets using user-defined byte masks, enable or disable packet tapping, and forward the desired data to the network stack. In addition, receive buffer settings can be dynamically configured. Adapter and hardware filters, such as promiscuous mode, can also be adjusted.

Demo Limitations:

  • demo has full functionality but is limited to 5 minutes operation time
  • then "receive & transmit" is suspended for 10 minutes
  • adapter handling is limited to scanning the target for supported adapters
  • event notification and translation of additional adapter properties require a licensed version
     

Generic:

  • configurable and detailed file logging which allows to select log levels for different (sub)parts
  • support of several concurrent bRAWcap handles to the same adapter
     

Adapter:

  • possibility to scan the target for supported adapters
  • translation between several adapter information
    (GUID, MAC, Description, FriendlyName)
  • reading current adapter properties / states
    (speed RX/TX, MTU, IPv4/6, operation, connection)
  • event notification on adapter changes
     

Monitoring:

  • multiple receive packet drop counters for different drop reasons and locations
  • multiple receive packet counters for different locations, e.g. at NIC level,
    driver before/after filtering
  • counter for the number of packets sent/received by the application

* Mandatory item

  • receive single packets without additional buffer handling
  • receive multiple packets by configurable API buffer(s) with callback registration
  • VLAN tagging support
  • filtering packets with user defined byte mask filter
  • (de)activate packet indication - forwarding to network stack
  • dynamic configuration of driver receive buffers
  • configuration of adapter or hardware filters (applied directly on the NIC), e.g. promiscuous mode
  • choose between several receive timestamp modes (system time, QPC, hardware timestamp) depending on adapter capabilities
  • configuration of direction which allows to select different receive modes, e.g. only received packets from NIC, only transmitted packets on NIC - from upper network stack or both
