Share Article

Rivulet Communications today announced that it has been issued US patent #7,453,885, "Network Connection Device," for its wide-area network (WAN) Internet Protocol (IP) network Quality of Service (QoS) technology. Rivulet's breakthrough packet scheduling technology, known as Dynamic Synchronization Technology (DSTâ„¢) enables guaranteed delivery of real-time packets over IP networks.

Our packet transmission system is successfully enabling difficult real-time applications to operate flawlessly for our customers on real-world Ethernet networks

Rivulet Communications, whose technology dramatically improves the performance of Ethernet networks, today announced that it has been issued US patent #7,453,885, "Network Connection Device," for its wide-area network (WAN) Internet Protocol (IP) network Quality of Service (QoS) technology. This new technology enables the same guaranteed performance on IP networks that Rivulet's first patent does for local Ethernet networks.

Rivulet's breakthrough packet scheduling technology, known as Dynamic Synchronization Technology (DSTâ„¢), enables guaranteed delivery of real-time packets. The system operates on ordinary standards-based routers and switches. Rivulet's technology prevents packets from arriving simultaneously in router queues, thus eliminating unnecessary loss, jitter and latency. Ethernet and IP networks without DST will not provide guaranteed delivery of real-time traffic on scaled networks. Legacy approaches to solving this problem either have been too rigid, are difficult to engineer and maintain, or require expensive purpose-built packet switching equipment.

"Our packet transmission system is successfully enabling difficult real-time applications to operate flawlessly for our customers on real-world Ethernet networks," said Edward Kennedy, Rivulet president and CEO. "Now our wide-area network packet scheduling solution can provide the same quality for IP networks, on a global basis."

Benefits of the new IP WAN packet scheduling system include:

  • Enables high-bandwidth, visually lossless video transmission over IP networks.
  • Supports other critical transmission applications such as lossless circuit emulation, and ultra-reliable command-and-control systems.
  • Allows the creation of shared, wide-area diagnostic-quality medical video networks, production-quality video media networks, and identification-quality surveillance video networks on IP infrastructure.
  • Greatly increases network efficiency and operating effectiveness.
  • Improves the performance of existing IP networks.
  • Features automatic flow engineering for simplified management.
