Research on Self-healing Ring and Protection Mechanism of SDH

Today all sectors of society rely increasingly on information exchanging. This situation raises demands for communication networks capable of transmitting information more and more timely and accurately. SDH self-healing protection is one of the methods propposed for keeping modern high-volume fiber-optic network safe and survivable. Sub-channel protection of self-healing ring and multiplex section shared protection ring. This paper describes the classification of self-healing, self-healing mechanism of the...
