Embodiment
Understand and realization the present invention the existing embodiments of the invention of describing in conjunction with the accompanying drawings for the ease of persons skilled in the art.
For convenience of description, be that example describes with the testing apparatus of the network board that comprises two network boards and two testers below.As shown in Figure 3, the invention discloses a kind of testing apparatus of network board, comprise: two network boards, described two network boards wherein one be tested network board, another piece is the instrument network board, tested network board can link to each other by keyset with the instrument network board, also can link to each other by cable or optical fiber; Two testers, two testers link to each other with tested network board or instrument network board respectively, perhaps wherein one link to each other with tested network board, another links to each other with the instrument network board; Keyset, it is used to connect tested network board and instrument network board; Line interface base (for convenience, being line interface base 1 and line interface base 2 among the figure), it can make tester link to each other with tested network board or/and instrument network board.Introduce each part of testing apparatus below in detail.
Two network boards, wherein one is tested network board, another piece is the instrument network board, described instrument network board can be identical with tested network board, promptly, the port number of instrument network board is identical with the port number of tested network board, the instrument network board also can be inequality with tested network board, the port number that is the instrument network board can be inequality with the port number of tested network board, according to the present invention, preferably, the number of instrument network board port is more than or equal to the number of the port of tested network board.When network board had outside port, it can directly pick out by connections such as cable or optical fiber so that link to each other with other parts (as another piece network board, line interface base, tester or keyset); When network board does not have outside port, its can only by keyset with link to each other with other parts (as another piece network board, line interface base, tester or keyset).
According to the present invention, by using an instrument network board to be used as the access diverter switch of tested network board port, can form various path according to the configuration of instrument network board or tested network board, thereby test the access or the exchange situation of the data of the individual channel of being formed, assess the performance of tested network board.
Two testers, it can be commercial tester, as SmartBits etc.In order to test network board, need two testers, with the difference between the input and output relatively, thereby assess the performance of tested network board.
Keyset, it is used to connect tested network board and instrument network board;
Line interface base, the effect of described line interface base are to change between switching network port and standard instrument interface, thereby tester is linked to each other with tested network board or/and instrument network board.
According to the present invention, the testing apparatus of network board disclosed by the invention does not re-use a large amount of line interface base and is used as bridge between switching network and tester, at most only uses two line interface bases and two testers.Thereby saved a large amount of line interface base and tester, saved testing expense.
The invention also discloses a kind of method of testing of network board, described method of testing comprises: configuration tool network board and tested network board, to form test access; First tester of test access one end produces data, and sends the data that produced by test access to second tester of the test access other end; The data that the data of sending according to first tester and second tester are received are judged the performance of the network board of this test access.
Fig. 3 shows a kind of connection example of testing network board.Two line interface bases respectively go out a port and are connected to commercial tester, as SmartBits etc., internally respectively go out a port and are connected respectively on the port of tested network board and instrument network board by keyset.Two N-1 remaining ports of network board are are directly received and dispatched intersection by keyset, an a pair of company.Like this, formed test data path is as follows.
Tester, line interface base 1, tested network board N port-VLAN (VLAN) forwarding-tested network board N-1 port, keyset, instrument network board 2 ports-VLAN transmits ...,-instrument network board N-3 port, keyset, tested network board 4 ports-VLAN forwarding-tested network board 3 ports, keyset, instrument network board N-2 port-VLAN forwarding-instrument network board N-1 port, keyset, tested network board 2 ports-VLAN forwarding-tested network board 1 port, keyset, instrument network board N port-VLAN forwarding-instrument network board 1 port, line interface base 2, tester.Under this pattern, can disposable all switching ports be traveled through, test intensity is big, and speed is fast, efficient is high.
Find that in test data transmit-receive goes wrong, as error code or data-bag lost occur, can be by changing the port vlan setting, forwarding object between flexible assignment port, reduce the port number of linking data link, form different test accesss, thereby can carry out fault location fast.
Can between two network boards, form different test accesss by changing the VLAN setting, as between two gigabit network board ports, forming all standing test access that detours back and forth, also can form the test access that part covers, thereby can satisfy testing requirement easily to switching performance between each port of network board, fully simulate network board actual conditions in actual applications, existing fault in the network board is located fast, so that fix a breakdown as early as possible.
As shown in Figure 4, for network board have can direct-connected outside port with external equipment situation.Can make full use of these outside ports, make between the outside port of two network boards to connect, or directly link to each other, can dispense line interface base like this, make up more simple test device with tester by outside port by cable or optical fiber.Like this, test access shown in Figure 4 is as follows.
Tester, tested network board N port-VLAN forwarding-tested network board N-1 port, cable or optical fiber, instrument network board 2 ports-VLAN forwarding-instrument network board 3 ports, cable or optical fiber, tested network board N-2 port-VLAN forwarding-tested network board N-3 port, keyset, ..., instrument network board N-2 port-VLAN forwarding-instrument network board N-1 port, keyset, tested network board 2 ports-VLAN forwarding-tested network board 1 port, keyset, instrument network board N port-VLAN forwarding-instrument network board 1 port, line interface base 2, tester.Under this pattern, can disposable all switching ports be traveled through, test intensity is big, and speed is fast, efficient is high.
Should be noted that, in above-mentioned test process, the tester at test access two ends both can produce data simultaneously, by test access the tester of data to the opposite end that is produced sent then, also can produce data respectively, by test access the data that produced be sent to the opposite end tester then.At last the data that received of data that produced according to the transmitting terminal tester and receiving terminal tester are judged the performance of the network board of this test access.
It should be noted, the embodiment of the invention has only been described thought of the present invention with the situation of a tested network board, an instrument network board, the present invention goes for the situation of at least two tested network boards and an instrument network board equally, perhaps the situation of at least two instrument network boards and a tested network board; Or the situation of at least two tested network boards and at least two instrument network boards.
Therefore, according to the present invention, can make things convenient for, test efficiently network board, fault location is convenient, makes that the maintenance of network board is simple.
Though described the present invention by embodiment, those of ordinary skills know, without departing from the spirit and substance in the present invention, just can make the present invention that many distortion and variation are arranged, and scope of the present invention is limited to the appended claims.
