METHOD FOR PREEMPTING THE PRIORITY OF THE LOWEST PRIORITY CABLE WHEN THE HIGHEST PRIORITY CABLE IS FAILURE

摘要

That of three cabled communication networks terminates at four individual landing points in two individual landmasses (one), and this method carries the business (1-4) of four grades, and the business of minimum rank is to try to be the first in failure. That terminated cable of switch element in each landing point and switch logic, by these various ranks traffic road by failure scenario response. It is a kind of that of this three cabled communication networks being installed comprising steps of being laid with the bandwidth X (401) of the first cable in landing point (422,425), each plot (A, B group), then other landing points (424,427) each landmass () being laid between the bandwidth X (402) of the second cable. Third connecting cable bandwidth be at least 2X (404,403,406,405,403,407) tool there are four end (422,424,425, (4040 are laid between the website of two panels land 2X, wherein one end is connected to each land website, and at least bandwidth of X is connected to each land website.
