InMon Corp. Revolutionizes Network Traffic Shaping and Control

San Francisco, California — Apr. 1, 2009 — InMon Corp. announced the immediate availability of Traffic Sentinel 4.0, which includes a revolutionary new control module for shaping traffic on large campus networks.

"Traffic Sentinel has always provided unparalleled visibility into network traffic; the wide support of the sFlow® standard among switch vendors allows Traffic Sentinel to build up a detailed, real-time picture of traffic from every switch in the network," said Peter Phaal, President, InMon Corp. "We realized that most customers already have traffic control functions built into their switches, but that these features were hardly ever used. The breakthrough was to close the loop and use Traffic Sentinel's detailed knowledge of network traffic and topology to automatically deploy targeted traffic controls."

Traffic Sentinel's traffic controller (pat. pend.) has significant advantages over other solutions currently on the market:

  • Scalable: controls are distributed among the switches in the network.
  • Low cost: controller uses capabilities of devices already in the network; no additional hardware is required.
  • High performance: the monitoring and control mechanisms are implemented in hardware on the switches and run at wire speed.

The visibility and control that Traffic Sentinel provides is a vital tool for containing network costs. Traffic analysis identifies wasteful traffic that can be eliminated from the network and the control functionality ensures quality of service during peak periods. Combined, these two capabilities help avoid costly and unneccessary upgrades and provide information to target network spending to areas where it will be most effective.

"We were having problems with the large amount of bandwidth consumed peer-to-peer traffic on our campus network of nearly 20,000 users," said Arthur Clune, The University of York. "Traffic Sentinel's quota controller continuously tracks the small number of users responsible for the bulk of traffic on the network, automatically instructing our switches to mark the traffic as low priority."

Traffic Sentinel fully supports the sFlow® standard for monitoring layer 2/3 switches; available in equipment from most leading network equipment vendors, including: 3Com (Nasdaq: COMS), Alcatel (CGEP: PA, NYSE: ALA), Brocade (Nasdaq: BRCD), Extreme Networks (Nasdaq: EXTR), Force10 Networks, Hewlett Packard (NYSE: HPQ), Hitachi (NYSE: HIT) and Juniper Networks (Nasdaq: JNPR).
