Abstract
A method for controlling address number in an address form in network is carried out by adding a control mechanism and an auto agingout mechanism in its learning function so as to lock the address form when the address number is larger than the preset value and to abandon the follow-up packets with incongruent addresses in order not to fill up the address form, and shifting the concerned data in an addrss if it is not used in a preset period so as to empty a space for learning a new address.
Description
Technical field
The present invention relates to the network switch technology, the control method of address number in especially a kind of address form of network switch.
Background technology
Press, at present in second too on the network (Ethernet), the second of different sections too network 1,2 all is connected with more than one network switch 3 (switch), consult shown in Figure 1, this interchanger can be a network equipment with a plurality of connectivity ports (port), no matter its outward appearance is piled up by the plurality of networks device forms, or only be single network equipment, as long as borrow different bridge joint agreement package (BridgeProtocol Data Units between these interchangers, be called for short BPDUs), link up each other, be the alleged network switch of the present invention.
These interchangers 3 are main in order to the packet information to being transmitted between the heterogeneous networks section, monitor, when interchanger receives the package that a certain section network transmits, controller on the interchanger will be at the purpose and the address, source of package, address form (Address Table) 31 in its data bank, compare with its address of having write down, if find the destination address of this package, the end host 4 that belongs to same section network, interchanger promptly abandons this package, and do not do any transmission, to finish the filtration (filtering) that package is transmitted, if the address, source of finding this package not in this address form, then adds it, to finish the dynamic login to this packet source address.
Therefore, address form in the network switch is mainly in order to determine the foundation of packet-switched approach, the setting program of present this address form, mainly go up additional a plurality of information in a lot of physical address (MAC address), to set, its operating type can be earlier by the user on the network terminal main frame with these information inputs after, download (Download) network switch again, or directly reach an agreement on by network management by the user, set physical address and information thereof one by one, its program is not only quite time-consuming, and makes mistakes easily again.
In addition, because general legacy network interchanger all possesses study (learning) function, the network management personnel can't be easily with its address form, locked (locking), cause the address, source of unwarranted end host, can take the storage area of this address form arbitrarily, and destination address when the package that network switch received, when not being recorded in this address form (that is not learnt) by this network switch, then this package will be exchanged to other all connectivity ports, form the unnecessary waste of this network switch on frequency range utilizes.
In recent years, because the network market is popularized for general community and family gradually, network system supplier utilizes each connectivity port on the network switch, is connected with each family, makes the plural platform computer of being installed in each family.Can pass through this connectivity port simultaneously, with second network system line mutually too, with the vast information on the share web.So, if network system supplier can not be to the computer number of each user side online, effectively controlled, or suitably limited, the huge package of quantity then, when swarming network simultaneously, or when the huge undesired package of quantity taking place pouring in network, all may take the address form of network switch moment, cause spendable frequency range and reduce rapidly.So, on a community network, the package that contains different addresses most probably because of the undesired generation of a certain user side in a large number, and cause being taken with the address form of the network switch of its line, and these packages are carried out unnecessary expansion to be broadcast, take spendable frequency range undesiredly, make the spendable frequency range of other user sides successively decrease, even the thing of network takes place to use.
Press, the address learning method of existing network interchanger mainly can be distinguished into following two kinds:
1, the self-teaching function of address form is provided by webmastering software, in this practice,, can not be limited or adjust at the size of the address form of each connectivity port though the size of the address form of network switch is had certain restriction.
2, finish the port learning functionality by the hardware of network switch, in this practice, first address (source address), source that each connectivity port of network switch only learns to be received, its shortcoming is that this network switch is when learning the address number of each connectivity port, because of its hardware can't be adjusted and control, and can't provide overtime information timing (the auto aging out timer) function of deletion automatically, so if there are 10 computers in a family, but each time point has only a computer to connect to the Net, then this network switch causes it only to allow an electricity to use too network of second from start to finish because of only learning address (source address), a source.
Summary of the invention
Because the address number in the address form of each connectivity port in the aforementioned conventional network switch, can't suitably be adjusted or be limited the problems that cause of difficulty, the inventor is the control method that works out address number in a kind of address form of network switch, with in the learning functionality of network switch, set up a controlling mechanism, make arbitrary connectivity port of this network switch, the address number of learning detecting, but when surpassing predefined maximum learned addresses number, promptly, lock (locking), stop study this address form, and give up the package of follow-up received mail returned on ground of incorrect address, to prevent on this network switch, pour in the huge undesired package of quantity, and the thing that this address form is taken, significantly promote the frequency range of network switch, and efficient on keyholed back plate and fail safe.
A purpose of the present invention, be after network switch receives a package, can with the address of having write down in its address form, compare, if find the address of this package, when being consistent with the address of being learnt in this address form, promptly this package is exchanged, if do not find the person of conforming to, and the address number of having learnt, when surpassing on this connectivity port predefined maximum number as yet,, be recorded in this address form then with the address, source and the relevent information of this package, and the address number that preestablishes study in this connectivity port subtracted one, the address number of learning up to this connectivity port, when having surpassed this predetermined maximum number, the beginning is given up (not carrying out packet-switched) with the package of follow-up received mail returned on ground of incorrect address.Therefore, the present invention can pass through webmastering software, sets the address number that can learn on this connectivity port respectively, with the user's number on the different connectivity ports of effective control.
Another object of the present invention, be on this network switch, to set up the automatic delete function of an overtime, make the arbitrary address and the relevent information that in this address form, have write down, when overtime is not used again, be about to this address and relevent information and in this address form, remove,, make this connectivity port can learn a new address again with vacating space, and it is added in this address form, reach and regularly upgrade the function that network uses present situation automatically.
