Accompanying drawing explanation
Fig. 1 is the schematic block diagram of existing equipment protection scheme;
Fig. 2 is that present embodiment is based on the chip-stacked schematic diagram with the protective device of port trunking;
Fig. 3 is the flow chart of the guard method of the equipment of present embodiment.
Embodiment
Present embodiment is based on the system interconnection framework of Ethernet; what realize between each primary and backup master control borad is chip-stacked; and the port being connected to same slot on same business board of each master control borad is carried out port trunking, thus set up a complete closed data transmission and protection channel.
Chip-stacked (also claiming chip cascade) be by more than two or two chips by high-speed channel interconnected (sometimes needing the cooperation of communication packet form or communications protocol), realize effect multiple chips being modeled to a chips.
Port trunking is that multiple trunking is become a port, thus improves the bandwidth of port.
Chip-stacked generation is to increase chip capacity and interface quantity, with the function of expensive chip.In present embodiment, by the chip of more than two or two be positioned over respectively on master control borad, be modeled to a chips, main purpose is not capacity increasing, but the port analog of the chip be positioned on different master control borad is become the port on a chips, because different chips is placed on different master control borad, chip stack is just equivalent to active and standby master control borad after building up one be same plate, on standby usage master control borad, the information interaction of more than two or two chips has been modeled to the information interaction between a chips different port, when switching generation, the switching rate of active and standby master control borad will improve greatly, on chip-stacked basis, recycling port trunking, thus realize pretection switch fast.
Below in conjunction with accompanying drawing, present embodiment is described in detail.
As shown in Figure 2, master control borad is configured with CPU, three layers/Layer2 switching chip, wherein, L3 Switching chip can select the BCM56XXX series of BroadCom company, and that supports by HiGig interface (physical layer is the transmission rate of XAUI interface, maximum 10Gbps) is stacking; Business board is configured with CPU, Layer2 switching chip.
After the exchange chip on each master control borad is stacked into a chips, the port being connected to same business board is polymerized, is modeled to a port; In business board side, the port linking active and standby NCP is respectively polymerized.After completing polymerization, the passage between business board to active and standby NCP aggregates into a passage, when master control borad generation masterslave switchover, can realize switching of active and standby NCP by the flow equalization in converging channels.
As shown in Figure 3, the method that present embodiment realizes equipment protection comprises:
Step 301, chip-stacked by active and standby NCP carries out, and the port of the same slot active and standby NCP being connected to same business board is carried out port trunking, port business board side being connected respectively to identical slot on active and standby NCP carries out port trunking;
Step 302, when master control borad 2 is main control board, business board side uses the passage be connected with master control borad 2 of converging channels 2 and master control borad 2 to carry out information interaction;
Step 303, when the unexpected chain rupture of the backboard side Ethernet of master control borad 2, the corresponding switching chip port of business board can detect chain rupture in time, and by carrying out flow equalization on converging channels 2, to the information of master control borad 2 be sent to, send to master control borad 1 by the passage be connected with master control borad 1 of converging channels 2;
Step 304, master control borad 2 transmits activestandby state and switching control information by the stacked channels between master control borad 1;
Step 305, master control borad 1 is as main control board, and business board side uses the passage be connected with master control borad 1 of converging channels 2 and master control borad 1 to carry out information interaction, and detects the Link State between master control borad 1.
There is no opening and shutoff of Link in present embodiment, generally only need to run LACP(link aggregate control protocol), therefore, pretection switch can be completed in a short period of time.
The all or part of step that one of ordinary skill in the art will appreciate that in said method is carried out instruction related hardware by program and is completed, and program can be stored in computer-readable recording medium, as read-only memory, disk or CD etc.Alternatively, all or part of step of above-described embodiment also can use one or more integrated circuit to realize.Correspondingly, each module in above-described embodiment can adopt the form of hardware to realize, and the form of software function module also can be adopted to realize.The present invention is not restricted to the combination of the hardware and software of any particular form.
Certainly; the present invention also can have numerous embodiments; do not deviating from the situation of the present invention's spirit and essence thereof; those of ordinary skill in the art are when making various corresponding change or change according to the present invention; in every case done within the spirit and principles in the present invention any amendment, equivalent replacement, improvement, all should be included within protection scope of the present invention.
