Introduction
Karl Scheffer is a notable inventor based in Vancouver, Canada. He has made significant contributions to the field of communication networks, particularly in the area of constant bit rate clients and OTN technology. With a total of 3 patents to his name, Scheffer's work has had a considerable impact on the industry.
Latest Patents
One of Scheffer's latest patents is titled "Method and system for transporting constant bit rate clients across a packet interface." This patent describes a method and apparatus for signaling the phase and frequency of OTN and Constant Bit Rate (CBR) clients in an OTN network. The principles discussed are applicable when multiple stages of OTN multiplexing and demultiplexing are utilized. Additionally, it outlines a method to use the phase and frequency of an ODUk/ODUflex to adjust a local reference clock, enabling the recovery of the phase and frequency of a CBR client demapped from the ODUk/ODUflex.
Another significant patent is focused on "Control and coordination of ODUflex bandwidth resizing operation." This patent provides methods and systems for controlling elements in a signal path of a communication network to accommodate changes in the rate of a client signal. During the bandwidth resizing portion of ITU-T Recommendation G.7044, the nodes in the chain along the ODUflex(GFP) signal path change their output rates in parallel, avoiding FIFO over/underflow in the nodes. Certain embodiments of this patent provide mechanisms to synchronize and stabilize the nodes in a verifiable manner.
