Description
Technical field
The present invention relates to the router technology field, particularly a kind of router of supporting multi-groove.
Background technology
Router is one of network equipment important in the Internet, is mainly used in finishing protocol conversion between routing forwarding and the distinct interface etc.The capacity of router is professional groove position resource particularly, is an important indicator weighing router performance.More professional groove position means larger expansion space, can satisfy the demand of customer service upgrading and development aspect.
At present in router, the LPU(Line Processing Unit that is used for data retransmission, wiring board) and be used for the SFU(Switch Fabric Unit of exchanges data, network board) on the System planes backboard, in a row places, connect by the high-speed link on the System Backplane between SFU and the LPU.Shown in Figure 1 is the schematic diagram that router is supported 16 groove positions, has two rows, and 4 SFU are placed on the centre position among each row, and SFU each side places 4 LPU.If support more multi-groove, then need to continue in the SFU both sides to increase LPU, the length of high-speed link also can correspondingly increase between SFU and the LPU like this.Because the performance of high-speed link can worsen along with length increases, so the quantity of router support groove position will be restricted, and generally is no more than at present 20 groove positions.
Although can adopt multi-chassis cascading system extension number of slots amount, need to introduce Cluster Central Chassis and light interconnect devices, power consumption and the cost shared of each wiring board significantly rises than single frame system like this, is difficult to a large amount of deployment in the practical application.Therefore, how in individual router equipment, to support more groove position, and prior art also there is not corresponding solution.

Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, embodiment of the present invention is described further in detail below in conjunction with accompanying drawing.
Referring to Fig. 2, one embodiment of the present of invention provide a kind of router of supporting multi-groove, comprise: wiring board 20 and groove position group 10, groove position group 10 comprises at least three groove bit locations, each groove bit location comprises at least one groove position, groove bit location in the above-mentioned groove position group 10 forms polygon in the backboard side, and wiring board 20 is inserted in the groove position in the groove position group 10.
In another embodiment of the present invention, router also comprises: network board 30, network board 30 is mainly used in exchanges data.According to network board 30 and the polygonal position relationship that is comprised of in the backboard side the groove bit location in the groove position group 10, network board 30 has two kinds of modes of emplacements:
The first, referring to Fig. 3, network board 30 can be positioned at the polygon outside, is inserted in the groove position in the groove position group 10, and is connected with wiring board.
For instance, each network board can be connected with any one wiring board, only schematically shows the part annexation among Fig. 3.
The second, referring to Fig. 4, network board 30 can be positioned at the polygon inboard, and is connected with wiring board.For instance, can the network board slot be set in the polygon inboard, network board 30 can be inserted in the network board slot.
For instance, network board can be connected by one or several modes in cable, optical cable or the printed circuit board (PCB) with wiring board.
When network board 30 places polygon inboard, can shorten the length of the link that connects network board 30 and wiring board 20, improve link performance.Owing to shortened the length that connects the link between network board and the wiring board, lower to index requests such as the power of optical cable, dispersions when link is optical cable for instance, the also corresponding reduction of the cost of interconnection; Similarly, when link is cable, also can reduce the cost of interconnection.
In another embodiment of the present invention, the cross section of wiring board 20 can be for can being inserted in arbitrarily the shape in the groove position, but be rectangle, trapezoidal or similar trapezoidal shape generally speaking.When the groove bit location quantity that forms groove position group 10 is many, the polygon that groove position group 10 forms in the backboard side is exactly near semiellipse or near the shape of semicircle, referring to Fig. 5, at this moment the cross section can be set is trapezoidal or similar trapezoidal shape to wiring board 20, so that the distance between the part of two waists of described trapezoidal or similar trapezoidal shape close to the polygon is less than the distance between the part away from polygon, thereby better utilize the space, the backboard size is held more wiring board in unit.For the application's embodiment, network board 30 is the same with wiring board 20, and the cross section equally can be for can being inserted in arbitrarily the shape in the slot, but be rectangle, trapezoidal or similar trapezoidal shape generally speaking.The polygon that forms in the backboard side when groove position group 10 is during near semiellipse or near the shape of semicircle, it is trapezoidal or similar trapezoidal shape that network board 30 can arrange the cross section, so that the distance between the part of two waists of described trapezoidal or similar trapezoidal shape close to the polygon is less than the distance between the part away from polygon, thereby better utilize the space, the backboard size is held more network board in unit.
On the basis of the above embodiment of the present invention, the router in the embodiment of the invention can also comprise the MPU(Main Processing Unit that is responsible for Routing Protocol processing and equipment control, master control borad).The shape of the shape of master control borad and wiring board 20 or network board 30 can be identical, do not repeat them here.
Present embodiment is by arranging at least three groove bit locations in the group of the groove position of router, the groove bit location forms polygon in the backboard side, wiring board is inserted in the groove position in the group of groove position, in a row place with respect to wiring board, can hold more wiring board, thereby make the more groove of individual router support position; In addition, network board can be placed polygon inboard, thereby shorten the length of link between network board and the wiring board, improve link performance.
The above only is preferred embodiment of the present invention, and is in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
