Description
Technical field
The present invention relates to address information processing method and Apparatus and system, relate in particular on the management board that is provided with on the cabinet formula switch and the ply-yarn drill exchange chip address information processing method, and the Apparatus and system of carrying out this address information processing method.
Background technology
Switch is a plurality of data terminals of a kind of connection, for example connects the multiple pc machine, is used to the common equipment of realizing that message is transmitted between data terminal.For example cabinet formula switch is exactly a kind of common switch, is provided with a plurality of slots on it usually, the polylith ply-yarn drill of can pegging graft on the slot, and ply-yarn drill is formed message forwarding system jointly with the management board that is arranged in the cabinet formula switch.As shown in Figure 1, management board 1 links to each other respectively by management path 6 with the communication interface of first ply-yarn drill 21, second ply-yarn drill 22 and the 3rd ply-yarn drill 23, be used for and the mutual transfer management order of ply-yarn drill, first ply-yarn drill 21, second ply-yarn drill 22 and the 3rd ply-yarn drill 23 are configured, the message forwarding process is managed; Be respectively arranged with first port 31, second port 32 and the 3rd port 33 on first ply-yarn drill 21, second ply-yarn drill 22 and the 3rd ply-yarn drill 23, continuous with different data terminals respectively, for example link to each other with the 3rd PC43 with a PC41, the 2nd PC42, be used for receiving and sending message, the quantity of ply-yarn drill upper port is generally more than one, and several ports on each ply-yarn drill have unique port numbers respectively; Be respectively arranged with first exchange chip 51, second exchange chip 52 and the 3rd exchange chip 53 on first ply-yarn drill 21, second ply-yarn drill 22 and the 3rd ply-yarn drill 23, connect a plurality of ports on this first ply-yarn drill 21, second ply-yarn drill 22 and the 3rd ply-yarn drill 23 respectively, and link to each other by data path 7 with management board 1, be used to realize exchanges data.
The message that existing cabinet formula switch is transmitted can simply be categorized as broadcasting packet and unicast message.The destination address of broadcasting packet is the Media Access Control address (Media AccessControl, be called for short MAC) of a plurality of data terminals, and normal conditions are named place of destination locations not, and giving tacit consent to all data terminals is the purpose terminal.When broadcasting packet transmits, can be sent to each node in the network in network.In switch, can transmit broadcasting packet to all of the port except that receiving this message port.The destination address of unicast message is normally specified a data terminal for specifying the MAC Address of limited quantity data terminal, and the general portion that only can transmit is given the destination data terminal in network system.
The general work process that existing switch E-Packets is: when the exchange chip on the ply-yarn drill receives message from locally-attached port, at first parse the destination address of this message, if broadcasting packet then sends to and transmits behind the management board to all ports; If unicast message, then according to address stored table on the destination address inquiry exchange chip of message, so-called address table, i.e. storage＜address, port numbers〉set of two tuples, the address is the MAC Address of data terminal, and port numbers is the port sequence number that connects this data terminal, also comprises the positional information of the ply-yarn drill at this port place usually; By the inquire address table, exchange chip gets access to the destination data terminal that this message should send and is connected on which port of this switch, it is corresponding with which port on the switch promptly to inquire about this message destination address, when inquiring corresponding port, port numbers is set in the property value of this message, send message to management board so that be transmitted to corresponding opposite end, if the address table of exchange chip does not have the address information of storage purpose address and corresponding end slogan, in the time of promptly can't inquiring corresponding port, then set this message and should be transmitted to all of the port on this switch, thereby form broadcasting packet; After message sent to management board, management board was transmitted to message corresponding setting port or is broadcast to all of the port according to the attribute of message.In this process, management board sends administration order indication message forwarding process by the management path to each ply-yarn drill.
For making the data terminal address that exchange chip address stored table can storage switch upper port correspondence, common exchange chip hardware all has address information acquisition and recording function, also claims the learning functionality of address information.When exchange chip when port x receives certain message, can detect the source address in this message, promptly send the data terminal address of message, be assumed to MAC Address X, then can to gather the data terminal address of port x correspondence be MAC Address X to exchange chip, general＜MAC Address X, port x〉two tuples be stored in the exchange chip hardware, simultaneously this two tuple is sent to management board by the management path and backs up.The address stored table is used to administer and maintain the data terminal address of whole port correspondences in the management board.Exchange chip not only can be gathered address information from the message that self port receives, also can transmit and gather the data terminal MAC Address of source address in this message and corresponding port number the broadcasting packet that comes, other ports receive from management board, for example above-mentioned message is when being broadcast to port Y, the exchange chip at port Y place can be gathered equally, record＜MAC Address X, port x〉two such tuples.Storage accumulation by address information can form comparatively sufficient address table on exchange chip, reduce because of the uncertain broadcasting packet phenomenon that causes of the pairing port of message destination address as far as possible.The broadcasting packet phenomenon frequently occurs, will inevitably take the network bandwidth in a large number, increase the load of network node, cause unnecessary message to spread unchecked, and the follow-up negative effect of bringing is that each finish node that connects in the network all can be received the message that spreads unchecked out, promptly form broadcast storm and inundation phenomenon, and in fact most of message should be sent to specific node.After the calculated address is shown in exchange chip, limit by memory space, the phenomenon that address aging also can occur, so-called address aging, be exactly that exchange chip is being grown an end in the time, all do not detect when a certain port is received message, then the exchange chip data terminal that can be considered as this port corresponding address does not have response for a long time, this address should be deleted from address table.The address is in case after aging deleted, when this exchange chip is received the message that mails to this destination address once more, will broadcast in whole switch.When producing unicast message, the address aging phenomenon often appears on the exchange chip in the non-unicast path.
Exchange chip to the acquiring and processing method of address information as mentioned above in the prior art, first problem of its existence is: for cabinet formula switch, owing to there is the polylith ply-yarn drill, be laid with a plurality of ports on each ply-yarn drill simultaneously, and the collection of address information is to be finished by the exchange chip on the ply-yarn drill, so the exchange chip on each ply-yarn drill is independently to the acquisition and recording of address information, address stored information disunity on the different exchange chips, under normal conditions, other exchange chips of the address information that the part exchange chip collects can't collect, for some unicast message, the exchange chip on the non-unicast path just can't collect the pairing data terminal of unicast message port address; Second problem that prior art exists is: it is aging and deleted that the forwarding of unicast message can cause being arranged in the non-unicast message path address information in the exchange chip address table on the ply-yarn drill, still can form broadcasting packet when then receiving the message that mails to this address once more and mail to all of the port.Be example explanation both of these case below with Fig. 1, a message enters first exchange chip 51 of first ply-yarn drill 21 from first port 31, the sequence number of first port is A, the address of message source data terminal is MAC Address A, destination address is MAC Address B, and first exchange chip 51 can collect＜MAC Address A so, the first port A〉the binary address information, but because inquiry is less than MAC Address B corresponding port number, so this message becomes broadcasting packet.When this message was broadcast on second ply-yarn drill 22 and the 3rd ply-yarn drill 23, second exchange chip 52 and the 3rd exchange chip 53 also can collect＜MAC Address A, the first port A〉the binary address information.Then follow-uply receive destination address when being the message of MAC Address A from second port 32, because record corresponding address information on second exchange chip 52, then this message can form unicast message, directly can send to first port 31 of first exchange chip 21.But after forming unicast message, the 3rd exchange chip 53 can't collect second port, 32 pairing address informations on second ply-yarn drill 22, thereby produce first above-mentioned problem, address stored information disunity on each exchange chip.Second problem is embodied in: the 3rd ply-yarn drill 23 is not because message follow-up, that source address is MAC Address A re-sends on it after forming unicast message, so store in the 3rd exchange chip 53＜MAC Address A, the first port A〉address information will wear out deleted over time, after this more on purpose the location be the message of MAC Address A when the 3rd port 33 enters the 3rd exchange chip 53, this message will become broadcasting packet.Therefore, adopt the switch of existing exchange chip address information treatment technology when E-Packeting, can have more broadcasting packet, the inundation phenomenon occurs, increase network burden.
