Embodiment Construction

[0098] Spider-web routers can be divided into single-rack and multi-rack routers, and single-rack routers can be divided into single-layer structure or multi-layer structure, which will be introduced separately below.

[0099]Considering that in the spider web structure, when there are only two circles, it is a regular hexagonal structure with a center point, and the regular hexagon contains 7 nodes including the center point, so a single rack and a single layer are designed according to the capacity of 7 line cards (In addition to the data processing plane, the router often needs a control plane. The control board may be located on the same layer as the line card. In order not to damage the spider web structure, in the actual design, the capacity of a single layer should be greater than the position of 7 line cards) .

[0100] Since the line cards in the actual system are placed in parallel, the regular hexagonal structure should be "transformed", Figure 8 (a) 0~6 nodes, co...

Abstract

A spider-web router characterizes that it's a router of spider web composed of a spider structure and extended line-card group and multiple control cards connected with the line cards and on the same layer of the line-card group to make up of spider wires starting from a line-card of a shaft line nearest to the pole to rotate clockwise to organize all line-cards very well with the help of the central point and six shafts and line-cards are set uniformly-spaced which has very good expansion performance.

Description

technical field [0001] The spider web router belongs to the technical field of the core device router in the Internet. Background technique [0002] The router is the core device in the computer network. With the rapid development of the computer network, the user traffic increases rapidly, which requires that the capacity of the router must be continuously increased to meet this demand. Traditional routers based on a single-rack structure mainly increase the overall capacity of the router by increasing the processing rate of the line cards. However, in actual implementation, it is restricted by many factors such as chip processing speed, interface technology, board power consumption, etc., and it also brings great pressure to the switching network inside the router. [0003] Early routers were implemented entirely through software, which limited the router's performance to a large extent. The first-generation routers used a general-purpose CPU, and multiple interface card...
