Title:
A VIRTUAL PROTECTION METHOD AND MEANS FOR THE FIBER PATH
Document Type and Number:
WIPO Patent Application WO/2003/107565
Kind Code:
A1
Abstract:
The invention involves a virtual protection method for the fiber path. The method comprises the steps of: dividing the optical port into a plurality of minimum protection units in physics; then dividing the system into more than one logic system based on the minimum protection units; In each logic system, every station can work in each of the following modes: normal working mode, passing working mode, bridging working mode and switching working mode; when the station need protection, it can be switched from the normal working mode to the other working modes by means of the protection ways of multiplexed segment, sub-networks connection and channel. The invention also involves a virtual protection means for the fiber path. With the method and means presented above, the invention not only resolves the problems of the present protection ways, but also makes the transmission networking more flexible and makes the protection ways more suitable for the users' demands.
