Embodiment
Below in conjunction with each accompanying drawing, embodiment of the present invention technical scheme main realized to principle, embodiment and the beneficial effect that should be able to reach is at length set forth.
The problem existing in order to solve prior art, the embodiment of the present invention provides a kind of method of ether web plate level protection, as shown in Figure 1, comprises the following steps:
Step 101, main exchange are converged buttress according to source address and the destination address of business datum, determine the also transmission path of record traffic data; According to transmission path, business data transmission is arrived to treatment facility corresponding to destination address;
The transmission path that plate records described business datum is converged in step 102, each standby exchange; Each standby exchange is converged plate all and main exchange is converged and between plate, set up protection relation;
Step 103, when plate is converged in main exchange in normal operating conditions, main exchange is converged input and output physical link corresponding between plate and treatment facility in state of activation, and each standby exchange is converged input and output physical link corresponding between plate and treatment facility in closed condition; When plate is converged in main exchange in abnormal operating state, close main exchange and converge the input and output physical link that plate is corresponding, activate a standby exchange and converge the input and output physical link that plate is corresponding, will standby exchange converge plate and switch to main exchange and converge plate use.
Concrete, business board sends to exchange by 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 is comprised that plate is converged in a main exchange and plate is converged at least one standby exchange.Meanwhile, a plurality of business boards all can converge board component by this exchange and send business datum.As shown in Figure 2, suppose to have a service board 21, it converges physical link that plate 22 and all standby exchanges converge plate 23 all in state of activation in up direction and main exchange, namely in up direction and main exchange, converges plate 22 and all standby exchanges are converged the port status that plate 23 is corresponding and are LINK UP state; At down direction, business board 21 and main exchange are converged physical link between plate 22 in state of activation, the physical links that converge plate 23 with all standby exchanges are all in closed condition, namely, only converging with main exchange the port status that plate 22 is corresponding is LINK UP state, converges the port status that plate 23 is corresponding be LINK DOWN state with all standby exchanges.Like this, can, so that the business datum that business board sends can arrive main exchange to converge plate and allly converge plate for exchanging, so that converging plate, active and standby exchange all can record the transmission path of this business datum.Certainly, also can be set to closed condition at up direction business board 21 and the standby physical link converging between plate 23 that exchanges, as shown in Figure 3, in this case, standby exchange is converged the mode that plate 23 can only adopt synchronous main exchange to converge the information such as transmission path in plate 22 and is carried out information recording.
And, at the down direction physical link that only main exchange is converged between plate and business board, be state of activation, therefore, only main exchange is converged the relevant information that plate can return to treatment facility and is sent to this business board.When plate is converged in this main exchange in abnormal operating state, by and this main exchange the ascending physical signal link and the descending physical link that converge between plate all close, ascending physical signal link and the descending physical link between plate converged in the standby exchange that activates and enable.Wherein, can switch the exchange active and standby exchange of converging in assembly by peripheral control unit simultaneously and converge the physical link state in plate and business board, also can converge in the controller in assembly same switch logic is set with exchange by the controller in business board, guarantee that both switchings are consistent.
Exchange is converged main exchange in board component and is converged plate and receive after this business datum, determines the transmission path of this business datum, and record this transmission path according to the source address of this business datum and destination address.Then, according to transmission path, business data transmission is arrived to treatment facility corresponding to destination address.Meanwhile, the transmission path that plate also records this business datum is converged in each standby exchange, so that when plate cisco unity malfunction is converged in main exchange, replaces main exchange and converges plate and carry out business data transmission.Preferably, the transmission path of plate record is converged in this standby exchange, can obtain according to the source address of business datum and destination address, and the record that also can converge plate by synchronous main exchange obtains.Preferably, the relevant informations such as transmission path that converge plate record in order to ensure each standby exchange converge with main exchange record in plate identical, and plate is converged in each standby exchange needs main exchange described in real-time or Timing Synchronization to converge the transmission path in plate; Or each standby exchange is converged plate in real time or regularly the transmission path of local record and main exchange are converged to the transmission path recording in plate and compare, if incomplete same, different transmission paths is updated to this locality, or the transmission path update all that main exchange is converged in plate arrives local.
And each standby exchange is converged plate and all converged plate with main exchange and set up protection relation, concrete, main exchange is converged plate and is converged plate and be connected with the corresponding ports for the treatment of facility respectively for exchanging with each; Main exchange is converged plate and is connected each standby exchange and converge the input/output terminal between plate and treatment facility; Each standby exchange is converged plate and is all connected main exchange and converge the input/output terminal between plate and treatment facility, and for example, as shown in Figure 4, main exchange is converged plate 41 and is connected with the first port for the treatment of facility 43; Standby exchange is converged plate 42 and is connected with the second port for the treatment of facility 43; Main exchange is converged the standby exchange of plate 41 connection and is converged the input/output terminal (trapezoidal portions in figure) between plate 42 and treatment facility 43; Standby exchange is converged the main exchange of plate 42 connection and is converged the input/output terminal between plate 41 and treatment facility 43.When the number that converges plate when standby exchange is greater than one, it is identical or similar with the connected mode in above-mentioned Fig. 4 that the connected mode that plate converges plate and treatment facility with main exchange is converged in each standby exchange, do not repeat them here.
Annexation based on shown in above-mentioned Fig. 4, as shown in Figure 5, when plate 41 is converged in main exchange in normal operating conditions, main exchange is converged input and output physical link between plate 41 and treatment facility 43 first ports and the second port all in state of activation; Standby exchange is converged input and output physical link between plate 42 and treatment facility 43 first ports and the second port all in closed condition; As shown in Figure 6, when plate 41 is converged in main exchange in abnormal operating state, main exchange is converged input and output physical link between plate 41 and treatment facility 43 first ports and the second port all in closed condition; Standby exchange is converged input and output physical link between plate 42 and treatment facility 43 first ports and the second port all in state of activation.Wherein, can according to main exchange, converge the activestandby state of state in place, malfunction or the current configuration of plate, judge that whether main exchange converge plate in normal operating conditions.For example, when main exchange, converge plate and be pulled out, or basic just inserting main exchange does not converge plate, can judge that this main exchange converges plate and occur situation not in place.Or, because this main exchange of actual needs is converged plate when being set to standby exchange and converging plate, can judge that this main exchange converges plate in abnormal operating state.Preferably, in the situation that the number that plate is converged in standby exchange is greater than one, when plate is converged in main exchange in non operating state, need to activates one of them standby exchange and converge plate, replace main exchange to converge plate.When activating standby exchange and converging plate, can determine at random that a standby exchange converges plate and activate, also can converge the overall performance of plate or standby exchange that certain determination of property parameter goes out to be activated converged plate according to each standby exchange.
Treatment facility receives main exchange and converges after the business datum of plate transmission, and this business datum is carried out to respective handling, then returns to business data processing information.Because treatment facility and standby exchange are converged physical link between veneer all in closed condition, therefore, only main exchange is converged plate and can be received this business data processing information, and according to the source address of this business data processing information and destination address, the business board of determining transmission path and receiving this business data processing information.Standby exchange is converged plate and can be converged by synchronous main exchange the record of plate, obtains the also transmission path of record traffic data processing of information.Also can be when treatment facility return to business data processing information, treating apparatus for activating converges the physical link of plate to standby exchange, make standby exchange converge the transmission path that plate can be determined business data processing information voluntarily.
Pass through foregoing description; can find out; the method of the ether web plate level protection that the use embodiment of the present invention provides; by arranging, plate is converged in a main exchange and plate is converged in a plurality of standby exchange; when plate cisco unity malfunction is converged in main exchange; be switched to standby exchange and converge plate, to guarantee the stability of Business Processing and the fail safe of business data processing.Because main exchange is converged the standby exchange of plate and each and is converged and all have physical connection between plate, not only make the speed of active and standby switching, and make standby exchange converge plate can synchronous main exchange to converge the information such as transmission path in plate, guarantee that service after switching data can normal process.
Below by specific embodiment, method provided by the invention is elaborated, as shown in Figure 7, suppose to have a business board 71, plate 72 is converged in main exchange and plate 73 is converged in a standby exchange, this business board 71 is at up direction, and plate 72 is converged in main exchange and the standby physical link converging between plate 73 that exchanges is state of activation; At down direction, and the physical link that main exchange is converged between plate 72 is state of activation, and the physical link that standby exchange is converged between plate 73 is closed condition; This main exchange is converged plate 72 and is connected with the first port for the treatment of facility 74; Standby exchange is converged plate 73 and is connected with the second port for the treatment of facility 74; Main exchange is converged the standby exchange of plate 72 connection and is converged the input/output terminal between plate 73 and treatment facility 74; Standby exchange is converged the main exchange of plate 73 connection and is converged the input/output terminal between plate 72 and treatment facility 74; Main exchange is converged input and output physical link between plate 72 and treatment facility 74 first ports and the second port all in state of activation; Standby exchange is converged input and output physical link between plate 73 and treatment facility 74 first ports and the second port all in closed condition.As shown in Figure 8, on the annexation basis shown in Fig. 7, the method that the embodiment of the present invention provides specifically comprises the following steps:
Step 801, business board send to main exchange by business datum by ascending physical signal link and converge plate and converge plate for exchange;
Step 802, judge that whether main exchange converge plate in normal operating conditions, if in normal operating conditions, continue execution step 803; Otherwise, execution step 808; Wherein, can according to main exchange, converge the activestandby state of state in place, malfunction or the current configuration of plate, judge that whether main exchange converge plate in normal operating conditions.For example, when main exchange, converge plate and be pulled out, or basic just inserting main exchange does not converge plate, can judge that this main exchange converges plate and occur situation not in place.Or, because this main exchange of actual needs is converged plate when being set to standby exchange and converging plate, can judge that this main exchange converges plate in abnormal operating state.
Step 803, main exchange are converged buttress according to source address and the destination address of this business datum, determine and record the transmission path of this business datum;
Step 804, standby exchange are converged transmission path that plate converges plate record by main exchange and are synchronized to this locality and carry out record; Concrete, the transmission path of plate record is converged in this standby exchange, can obtain according to the source address of business datum and destination address, and the record that also can converge plate by synchronous main exchange obtains.How no matter plate in standby exchange obtains transmission path record if being converged, the relevant informations such as transmission path that converge plate record in order to ensure each standby exchange converge with main exchange record in plate identical, and plate is converged in each standby exchange needs main exchange described in real-time or Timing Synchronization to converge the transmission path in plate; Or each standby exchange is converged plate in real time or regularly the transmission path of local record and main exchange are converged to the transmission path recording in plate and compare, if incomplete same, different transmission paths is updated to this locality, or the transmission path update all that main exchange is converged in plate arrives local.
Step 805, main exchange are converged plate by the physical link with the first port and the second port, and this business datum is sent to the treatment facility that destination address is corresponding;
Step 806, treatment facility are handled after this business datum, business data processing information is turned back to main exchange and converge plate;
Step 807, main exchange are converged plate this business data processing information are turned back to business board.
Step 808, carry out the active and standby plate exchange of converging, standby after exchange converged to plate and as new master, converge plate, continue execution step 802; Concrete, when plate is converged in main exchange in abnormal operating state, as shown in Figure 9, corresponding with Fig. 7, at down direction, the physical link state that business board 71 and main exchange are converged between plate 72 switches to closed condition, and the physical link state that standby exchange is converged between plate 73 switches to state of activation; The input and output physical link that main exchange is converged between plate 72 and treatment facility 74 first ports and the second port all switches to closed condition; The input and output physical link that standby exchange is converged between plate 73 and treatment facility 74 first ports and the second port all switches to closed condition.Now, if when business board sends business datum again, standby exchange is converged plate this business datum is processed, and guarantees the stability of Business Processing and the fail safe of business data processing.Detailed process that plate processes this business datum and main exchange are converged in this standby exchange, and to converge plate consistent, do not repeat them here.Preferably, in the situation that the number that plate is converged in standby exchange is greater than one, when plate is converged in main exchange in non operating state, need to activates one of them standby exchange and converge plate, replace main exchange to converge plate.When activating standby exchange and converging plate, can determine at random that a standby exchange converges plate and activate, also can converge the overall performance of plate or standby exchange that certain determination of property parameter goes out to be activated converged plate according to each standby exchange.
