OCS Granted Patent for Traffic Load Adaptive Network Physical Layer

Tuesday, July 07, 2009

Calgary, Alberta -- Optimum Communications Services, Inc. (OCS) has been awarded a patent on its innovation delivering realtime traffic load adaptive physical layer for communications networks. The patent in question can be found with its US Patent Number 7,558,260 via

This novel network physical layer (L1) optimization method enables providing premium quality, dedicated network services at cost below the prevailing, shared capacity based services. OCS' patented technology makes this possible through optimizing network capacity allocation according to packet-by-packet traffic load variations, resulting in that networks no longer need to be over-engineered for all possible packet (L2/3) traffic load distribution scenarios, as an adaptive L1 will provide maximized packet throughput with minimum theoretically sufficient total network capacity, reducing network costs proportionately to the number of customer sites to be interconnected.

"I like to see basic innovations in our industry -- OCS' new patent is clever and noteworthy, since it brings a fresh approach to packet service QoS, security and determinism at the operationally less costly layer 1," stated Michael Howard, Principal Analyst at Infonetics Research. "OCS' adaptive L1 technique should be considered since it performs optimization using end nodes, rather than relying on intermediate nodes, and thereby can achieve bypass of L2 and L3 nodes along a service delivery pathway."

Through emergence of such adaptive L1 optimized customer and application networking model, the industry can find a new direction after decade or more of complex effort to transition to a collapsed L2/3 packet-switched network cloud where different customer networks had to be kept virtually isolated at packet layer, as multiple client networks shared and competed for same physical layer connection and packet-switch capacity, causing ever increasing complexity costs and ongoing security concerns.

"Enabled by this innovation reducing physical layer capacity costs by an order of magnitude, it actually is more economical to implement individual application and customer networks over their dedicated L1 capacity pools, than it would be to mix different client networks to a common, cross-contract shared service provider capacity pool," remarked Mark O'Shaughnessy, OCS' Marketing VP. "By keeping unrelated traffic flows isolated already at the bottom of network protocol stack, the upper layer processing and administration can be greatly simplified and associated costs accordingly reduced, while each customer of these 'L1.5VPNs' gets highest achievable QoS and security."
