Press ReleaseCeterus Networks Awarded U.S. Patent For Framing ProtocolEconomical new protocol increases router port throughput beyond 10 Gbps RICHARDSON, Texas – Sept. 24, 2007 – Ceterus Networks, a provider of efficient and resilient Ethernet backhaul and enterprise transport solutions, today announced that it has been issued patent number 7,237,035 for its “frame structure” protocol technology by the United States Patent and Trademark Office. “Ceterus is squarely focused on developing faster and more economical transmission technologies that not only serve our customers in today’s Ethernet environment, but can also evolve to carry much higher data rates when fiber-optics take center stage,” said William Szeto, CTO of Ceterus. “Innovation has always been the core of Ceterus, and we will continue to produce more highly adaptable access solutions that will provide the best and most cost-effective transport technologies for our customers.” The new Ceterus protocol uses higher-speed, lower-power silicon technologies to increase the router port throughput beyond 10 Gbps, while minimizing memory requirements. This solution is more economical from the transmission system perspective because the data rate per wavelength is kept at 10 Gbps. In the future, as optical and transmission technologies evolve to carry higher data rates per wavelength over longer distances, such technologies can be easily incorporated into the new Ceterus protocol. This translates to more efficient and cost effective Ethernet transport for enterprises and carriers alike. In addition, it provides various levels of QoS while meeting stringent SLA requirements. Ceterus’ patented protocol keeps operating costs low by maximizing the throughput of each high-speed port by utilizing 10 Gbps point-to-point transmission lines which are more efficient than standard SONET framing protocol.
