Description of drawings
Fig. 1 is the process chart of hot drawing of the present invention;
Fig. 2 is the process chart that the present invention's heat is inserted.
Embodiment
For the detection of hot drawing, use two kinds of mechanism: interrupt (the hard detection) and status report message (soft detection); The processing that heat is inserted only is the registration triggering by business module, interrupts not triggering heat and inserts processing procedure.It all is to carry out at a new task space that all hot plugs are handled, and the priority of the task that this is new is equal to the priority of equipment state machine task; When hot plug is finished dealing with, this task withdraws from automatically.
The detection of hot drawing and processing mainly are the deletion of configuration information and the extraction backup of configuration information.As user's physics extract a module time, master control borad detects interruption, when finding to have module to be pulled out by equipment state machine (master control borad a period of time is not received the other side's heartbeat message), detecting that module inside this interrupts is pulled out, slot number according to module, check the running status of module, if the current running status of this module less than MODULE_MOD_READY, is not then carried out the processing of hot plug; Otherwise, then carry out the processing of hot plug; When ACTIVE MASTER (interruption) does not receive the status report message of certain business module for a long time, if this module current running status be not less than MODULE_MOD_READY, then carry out the processing of hot drawing.
With reference to figure 1, the processing of hot drawing comprises: (1) is from global configuration information (SHOW RUN), extract the configuration information relevant with this module, at first form and be pulled out the command block that plate is associated, to each command block structural feature keyword, search out the configuration information that comprises the corresponding command piece, and preserve in the global configuration information and the related command of module.(2) after module is extracted, at first all produce a NETDEV_DOWN incident for each port on the module, remove multidate information by the DOWN incident, secondly, the order of preserving is the configuration that is used for inserting at interface board back restoration interface plate, so after interface board is extracted, as long as carry out the order opposite with these order effects, just can remove the configuration information relevant, and in the fill order process, produce the corresponding apparatus notification event with extracting veneer; After finishing relevant configuration and removing, the contents in table of each port correspondence in the deletion NETDEV table and in the interface board, and produce the NETDEV_UNREGISTER incident.The most crucial task of L3 layer module is to handle the variation of routing table and ARP table during hot drawing.After professional version was extracted, the port DOWN incident of interface board was by notice chain function notice routing module, and routing module can re-route calculating, deletes corresponding route table items.This process can be handled and can reasonablely be connected with the hot drawing of L2 by the notice chain function that routing module is registered, so does not need special processing on the flow process.For the ARP table, after plank was extracted, the ARP table of learning from this plate had kept necessity, should aging deletion from system immediately.Delete all relevant QOS and ACL configuration software information by the call back function that the registration hot plug is handled.
(3) remove the context information of this module.
(4) to be died by the withdrawing pattern piece in order preventing, can to carry out this module and once restart.
Detection and processing that heat is inserted mainly are to realize the recovery of configuration information by issuing the software list item again.When new business board injected, it will send the register requirement message to master control borad, and ACTIVE MASTER (interruption) sends to this business module and replys, and the tagging position is that heat is inserted.Interface board begins to carry out synchronously with master control borad after receiving the registration response message, after a veneer inserts, current NETDEV data structure on the master control borad (not comprising the configuration relevant with extracting veneer of having preserved) need be synchronized to this interface board, and in hardware, dispose accordingly according to these software list items.With reference to figure 2, order is done following processing:
(1) create port and default VLAN, the operation of carrying out during with system start-up is the same substantially;
(2) the synchronous NETDEV tables of data of master control borad is to the interface board that inserts, send data after, master control borad waits for that interface board finishes hardware configuration;
(3) interface board carries out the relevant hardware setting according to this tables of data after the NETDEV tables of data, after interface board is finished hardware setting, sends the message informing master control borad;
(4) master control borad competitive list board type judges whether to be configured recovery;
(5) master control borad extracts and carries out the configuration order piece of preserving, and the interface board that inserts is configured.
(6) after master control borad is finished the configuration of interface board, open each port of interface board, make the interface board of insertion can carry out the business forwarding;
The most crucial task of L3 module was to handle the variation of routing table and ARP table when heat was inserted.
Professional version for new insertion need all be issued to this module with fib table, and the route that inserting rear port UP in addition increases also will issue in the lump.QOS and ACL module can realize recovering by registering the slotting CALL_BACK function of heat.
Simultaneously during insertion system, heat is inserted and handled is serial as a plurality of modules; Processing procedure for each module is the same.
