Embodiment
At length set forth to the main realization principle of embodiment of the invention technical scheme, embodiment and to the beneficial effect that should be able to reach below in conjunction with each accompanying drawing.
In order to solve the problem that prior art exists, the embodiment of the invention provides a kind of method of ether web plate level protection, as shown in Figure 1, may further comprise the steps:
Source address and the destination address of buttress according to business datum converged in step 101, main exchange, confirms the also transmission path of record traffic data; According to transmission path, business data transmission is arrived destination address corresponding processing equipment;
Concrete, business board sends to exchange with business datum and converges board component, by it this business datum is sent to treatment facility and carries out data processing, and this exchange is converged board component and comprised that a main exchange converges plate and be equipped with exchange with at least one and converge plate.Simultaneously, a plurality of business boards all can converge board component through this exchange and send business datum.As shown in Figure 2; Suppose to have a service board 21; It converges plate 22 in up direction and main exchange and is equipped with exchange with all and converges the physical link of plate 23 and all be in state of activation, just converges plate 22 in up direction and main exchange and is equipped with exchange with all and converges plate 23 corresponding port states and be LINK UP state; At down direction; The physical link that business board 21 and main exchange are converged between the plate 22 is in state of activation; Exchange the physical link that converges plate 23 fully with all and all be in closed condition; Just; Only converging plate 22 corresponding port states with main exchange is LINK UP state, is equipped with exchange with all and converges plate 23 corresponding port states and be LINK DOWN state.Like this, can be so that the business datum that business board sends can arrive main exchange to converge plate and exchanges fully with all and converge plate, so that the transmission path that plate all can write down this business datum is converged in active and standby exchange.Certainly; Also can and be equipped with the physical link that exchange converges between the plate 23 at up direction business board 21 and be set to closed condition; As shown in Figure 3, in this case, be equipped with exchange and converge the mode that plate 23 can only adopt synchronous main exchange to converge information such as transmission path in the plate 22 and carry out the information record.
And the physical link that converges between plate and the business board in the only main exchange of down direction is a state of activation, and therefore, only main exchange is converged the relevant information that plate can return treatment facility and sent to this business board.When this master exchange is converged plate when being in abnormal operating state, will and this master exchange the ascending physical signal link and the descending physical link that converge between the plate all close, ascending physical signal link and the descending physical link between the plate converged in exchanging fully of activating and launch.Wherein, Can switch the exchange active and standby exchange of converging in the assembly simultaneously through peripheral control unit and converge the physical link state in plate and the business board; Also can with exchanging to converge same switch logic be set in the controller in the assembly by the controller in business board, guarantee that both switchings are consistent.
Exchange is converged main exchange in the board component and is converged after plate receives this business datum, the transmission path of determining this business datum based on the source address and the destination address of this business datum, and write down this transmission path.Then, according to transmission path, business data transmission is arrived destination address corresponding processing equipment.Simultaneously, each is equipped with exchange and converges the transmission path that plate also writes down this business datum, so that when the plate cisco unity malfunction is converged in main exchange, the main exchange of replacement is converged plate and carried out business data transmission.Preferable, should be equipped with the transmission path that the plate record is converged in exchange, can obtain based on the source address and the destination address of business datum, also can obtain through the record that plate is converged in synchronous main exchange.Preferable, be equipped with exchange in order to ensure each and converge the relevant informations such as transmission path of plate record and converge write down in the plate identical with main exchange, each is equipped with exchange and converges that plate needs in real time or regularly synchronous said main the exchange converged the transmission path in the plate; Perhaps each is equipped with exchange and converges when firm and hard or regularly the transmission path of local record is converged the transmission path that writes down in the plate with main exchange and compare; If it is incomplete same; Different transmission paths is updated to this locality, perhaps will leads exchange and converge transmission path update all in the plate to local.
