Patent CA-2294693-A1 (CA)
Inventor: GRENIER GUY-LAVAL
IPC: H04J3/14
Filed: 2000-01-11
Abstract: A method and system for protecting virtual traffic travelling through a protected domain consisting of a bridge node connected to a selector node in a working path and a protection path. The method includes upon detecting failure of the traffic channels in the working path, the detecting node transmitting failure information to the selector node along the traffic channels and along an alarm channel in the working path. The method also includes the selector node initiating protection switching of the traffic channels as soon as it receives the failure information along the alarm channel.      According to the invention, the alarm channel has a sufficiently high priority relative to the traffic channels to allow the selector node to initiate protection switching before failure information is received along any of the traffic channels. Thus, protection switching can be initiated by the selector node prior to the receipt of alarm cells on traffic channels, which significantly reduced the time during which the traffic channels contain alarm cells. Advantageously, the invention helps prevent premature termination of the end-to-end traffic connection.

Filed: 1999-06-23
Abstract: A method for calculating the initial value in the Newton-Raphson method by synthesization using values retrieved from a small table stored in a memory by means of an arithmetic unit. The method of the invention is free from problems of conventional dividers such as a long operating time and a large circuit scale. The iterative calculation circuit of the Newton-Raphson method is mounted as an arithmetic circuit. A reciprocal calculating circuit having a short operating time, usable as a pipeline system, and exhibiting an improved throughput and a dividing circuit comprising the reciprocal calculating circuit are mounted. Part of the multiplying circuit included in the iterative calculation circuit is omitted by regarding the calculation precision, thus making it a compact iterative calculation circuit. Further by using the interim results of the calculation, the calculation precision is readily enhanced. Thus, a method for calculating the minimum size required for the table used for calculating the initial value is provided, and means for designing a circuit of a requisite minimum while fulfilling the required calculation precision is also provided.
