Embodiment Construction
[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0026] Currently widely used centralized mesh topology such as figure 1 shown. The present invention introduces a bus on each row and each column on the basis of the existing centralized mesh topology structure, and connects all routers on the row and the column together to form a redundant centralized mesh- bus structure. Its construction method includes the following steps:
[0027] Step 1, connect each router to 4 local cores.
[0028] figure 1 In , each small square represents a core, and the large square represents a router. Each group of 4 cores is connected to a local router.
[0029] Step 2. Arrange routers as a rectangular array closest to a square.
[0030] figure 1 There are 64 cores and 16 routers arranged in a square.
[0031] Step 3, each router is connected with its horizontally and vertically adjacent routers through a d...
