Embodiment
In the OAA framework, traditional network equipment is as a platform (being commonly referred to NFC), and this platform can integrated other manufacturers be developed various application plug-in cards (being commonly referred to IAC), such as IPS plug-in card etc.Communication pattern between NFC and the IAC generally includes four kinds: host mode, mirror image pattern, redirect mode and penetrate pattern.The related application that the introduction of more OAA technology can the REFERENCE TO RELATED people proposes is such as WO/2008/037159 and as the multinomial Chinese patent application of the basis for priority of this PCT application.
In the OAA framework, in four kinds of communication patterns of NFC and IAC, redirect mode is a kind of tightly coupled pattern, and other patterns then are tight couplings comparatively speaking.In redirect mode, message enters from the general service port of NFC, hit redirected rule and can be redirected on the OAA plate (comprising IAC), carry out turning back to NFC after OAA processes (such as network applications such as safety filtering or network speed limits) at the OAA plate and proceed traditional message repeating.
Please refer to Fig. 1, comprise master control borad, forwarding service plate, OAA agency board, network board and OAA plate based on the legacy network devices of OAA system.Wherein the OAA plate generally includes the OAA front card and transmits back card/back board.The list item of considering upper each forwarding service plate of NFC may there are differences and the versatility of scheme, in the prior art, guarantee the forwarding of message in order correctly to table look-up, what the message that needs to force OAA close coupling plate to return was gone to appointment acts on behalf of the veneer forwarding of tabling look-up.When configuration OAA plate return flow, need to specify special forward mode (L2-enhanced), also need to preserve configuration after the appointment and restart to allow configuration take-effective.In the scheme of Fig. 1, the network equipment need to provide separately the high standard veneer with agent capability (such as the forwarding service plate), this is so that the cost up of the whole realization of OAA framework, and the development cost of a common high standard veneer and Material Cost are quite significant.And the whole handling process of message is also long, at first message enters from the forwarding service plate, arrive the forwarding back card/back board of OAA plate through network board, arrive the OAA front card by the physical interface of transmitting between back card/back board and the OAA front card again, the OAA front card carries out delivering to the forwarding back card/back board by aforementioned physical interface again after the OAA processing, transmit back card/back board and determine that according to the communication between plates head message will be forwarded to the OAA agency board, message arrives after the OAA agency board, and the forwarding-table item that the OAA agency board is searched on the plate is carried out the message repeating flow process.The handling process of whole message can be with reference to the lines with arrow among the figure 1.
Please refer to the logic diagram that the present invention shown in Figure 2 uses the network equipment of OAA system, wherein the network equipment comprises master control borad, forwarding service plate, network board and OAA plate.Wherein the OAA plate generally includes the OAA front card and transmits back card/back board.Network board provides data channel and the control channel of communication between plates for whole OAA internal system.In the present invention, no longer need additionally to provide separately an OAA agency board to come to be the service of tightly coupled OAA plate.The present invention a kind of preferred embodiment in, realize the operation flow method of adjustment of the invention described above by the computer program on the transformation master control borad, wherein the CPU of master control borad reads this computer program and operation from memory, and the general processing procedure of this program may further comprise the steps:
Step 101 detects whether the OAA plate that inserts the network equipment is OAA close coupling plate;
Step 102, when detecting OAA close coupling plate, the order that refluxes of user oriented this plate of OAA close coupling plate is revised as open visible state from the shielding invisible mode, so that the user can issue the rule that refluxes and is back to forwarding back card/back board on the OAA plate with the message of control OAA close coupling plate by inputting this this plate backflow command triggers master control borad;
Step 103, after OAA close coupling plate was inserted into the network equipment, master control borad issued this plate backflow rule by control channel to the OAA front card, and the message after wherein this this plate backflow rule indication OAA front card will be processed sends to the forwarding back card/back board on the OAA plate.
Need to prove that step 102 is not the necessary step of the present invention, because the pattern that the OAA system also can adopt automatic detection to issue, such as it is regular to be designed to issue the backflow of this plate from trend OAA front card when master control borad detects the OAA close coupling plate insertion network equipment, thereby dispenses the step of the manual intervention as step 102.Certainly allowing the user to issue the rule that refluxes by control command is to embody suitable flexibility at some application scenarios.After OAA close coupling plate was inserted in the system, master control borad can be found according at least a default testing mechanism the insertion of OAA close coupling plate, and this testing mechanism can cover the detection of bottom hardware and even the various levels of upper layer software (applications).
Before not having the OAA close coupling plate insertion network equipment, the order that refluxes of this plate can be designed as and masks in other words this order to the user is invisible, because this moment, this plate refluxed order to user's meaning not, the order that refluxes of open this this plate also may cause user error to operate this order causing system's run-time error.After OAA close coupling plate inserted, master control borad can carry out the negotiation of various levels with OAA close coupling plate, and the backflow order can be open to the user after consulting to finish.Take the network equipment be the 75E series of switch that provides of H3C company as example, the order that refluxes of this plate can be: switch-mode OAA slot xx.Wherein xx represents the slot number on backboard (not shown) of Target Board.In preferred embodiment, the compatibility of support of the present invention and prior art, if such as the user wishes to continue to use the agency board in the prior art scheme, it can issue corresponding agency order that refluxes, take the 75E series of switch of H3C company as example, this agency refluxes and orders can be switch-mode l2-enhanced, the user issues after this order, master control borad can be correspondingly issues agency corresponding to the order rule that refluxes that refluxes with this agency to the OAA plate, carries out forward process on the agency board so that can be back to through the message after the processing of OAA front card.
