Description
Technical field
The present invention relates to router technology field, particularly a kind of router supporting multi-groove.
Background technology
Router is one of network equipment important in the Internet, has been mainly used in the protocol conversion etc. between routing forwarding and distinct interface.The capacity particularly business slot resource of router is the important indicator weighing router performance.More business slot means larger expansion space, can meet the demand of customer service upgrading and development aspect.
At present in the router, for the LPU(LineProcessingUnit of data retransmission, wiring board) and for the SFU(SwitchFabricUnit of exchanges data, network board) in a row place on System planes backboard, connected by the high-speed link on System Backplane between SFU and LPU.Be the schematic diagram that router supports 16 slots shown in Fig. 1, have two rows, in each row, 4 SFU are placed on centre position, and SFU each side places 4 LPU.If support more multi-groove, then need to continue in SFU both sides to increase LPU, between such SFU and LPU, the length of high-speed link also can correspondingly increase.Because the performance of high-speed link can worsen along with length increase, therefore router supports that the quantity of slot will be restricted, and is generally no more than 20 slots at present.
Although can adopt multi-chassis cascading system extension slot quantity, need to introduce Cluster Central Chassis and light network device, the power consumption that each like this wiring board is shared and cost significantly rise than single frame system, are difficult to a large amount of deployment in practical application.Therefore, how in individual router equipment, to support more slot, and prior art also do not have corresponding solution.
Summary of the invention

Embodiment
For making the object, technical solutions and advantages of the present invention clearly, below in conjunction with accompanying drawing, embodiment of the present invention is described further in detail.
See Fig. 2, An embodiment provides a kind of router supporting multi-groove, comprise: wiring board 20 and slot group 10, slot group 10 comprises at least three slot unit, each slot unit comprises at least one slot, slot unit in above-mentioned slot group 10 is at backboard side composition polygon, and wiring board 20 is inserted in the slot in slot group 10.
Wiring board 20 can have one or at least two.When wiring board 20 has at least two, in wiring board any two can be interconnected amongst one another.Such as, can be connected by cable or optical cable between any two wiring boards.For example, the function that the wiring board 20 in the present embodiment has comprises: the encapsulation of multiple link layer protocol and process; Data packet stream classification and packet filtering, monitor and Access Control List (ACL) for customer flow; Data buffer storage management and scheduling feature; Data retransmission is carried out according to transmitting; Identify control protocol message, and be forwarded to host CPU process by non-linear speed Processing Interface.
In another embodiment of the invention, router also comprises: network board 30, and network board 30 is mainly used in exchanges data.According to network board 30 and the polygonal position relationship be made up of in backboard side the slot unit in slot group 10, network board 30 has two kinds of modes of emplacements:
The first, see Fig. 3, network board 30 can be positioned at outside polygon, is inserted in the slot in slot group 10, and is connected with wiring board.
For example, each network board can be connected with any one wiring board, only schematically illustrates part annexation in Fig. 3.
The second, see Fig. 4, network board 30 can be positioned at inside polygon, and is connected with wiring board.For example, can arrange network board slot inside polygon, network board 30 can be inserted in network board slot.
For example, network board can be connected by one or several modes in cable, optical cable or printed circuit board (PCB) with wiring board.
When network board 30 is placed in inside polygon, can shortens and connect network board 30 and the length of the link of wiring board 20, improve link performance.Owing to shortening the length of the link connected between network board and wiring board, for example, when link is optical cable, lower to the index request such as power, dispersion of optical cable, the cost also corresponding reduction of interconnection; Similarly, when link is cable, the cost of interconnection can also be reduced.
In another embodiment of the invention, the cross section of wiring board 20 can for being inserted in arbitrarily the shape in slot, but be generally rectangle, trapezoidal or similar trapezoidal shape.When the slot element number forming slot group 10 is many, the polygon that slot group 10 is formed in backboard side is exactly close to semiellipse or the shape close to semicircle, see Fig. 5, at this moment wiring board 20 can arrange cross section is trapezoidal or similar trapezoidal shape, to make described two waists that are trapezoidal or similar trapezoidal shape little from the distance between the part away from polygon from the distance ratio between the part close to polygon, thus better utilize space, unit backboard size holds more wiring board.For the embodiment of the application, network board 30 is the same with wiring board 20, and cross section can for being inserted in arbitrarily the shape in slot, but be generally rectangle, trapezoidal or similar trapezoidal shape equally.When the polygon that slot group 10 is formed in backboard side is close to semiellipse or the shape close to semicircle, it is trapezoidal or similar trapezoidal shape that network board 30 can arrange cross section, to make described two waists that are trapezoidal or similar trapezoidal shape little from the distance between the part away from polygon from the distance ratio between the part close to polygon, thus better utilize space, unit backboard size holds more network board.
State on the invention on the basis of embodiment, the router in the embodiment of the present invention can also comprise the MPU(MainProcessingUnit of responsible Routing Protocol process and equipment control, master control borad).The shape of master control borad can be identical with the shape of wiring board 20 or network board 30, do not repeat them here.
The present embodiment by arranging at least three slot unit in the slot group of router, slot unit is at backboard side composition polygon, wiring board is inserted in the slot in the group of slot, in a row place relative to wiring board, more wiring board can be held, thus make the more slot of individual router support; In addition, network board can be placed in inside polygon, thus shorten the length of link between network board and wiring board, improve link performance.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
