Description
Technical field
The present invention relates to a kind of network card test system and method thereof, be meant especially a kind ofly can monitoring state of network to change and dynamically adjust system and the method thereof that the configuration parameter value of test program is carried out the network card test.
Background technology
In the network card test event, the transmittability test of network card is one of basic and the most important project, and general transmittability test mode all is network card to be tested to be seen through network coupled together, and carries out test program then to test according to the program of setting.The mode that tends to take transferring large number of data or transmit data for a long time in test program increases the transmission pressure that is produced when network card tested, and assesses the transmittability of network card under this transmission pressure then by this.
The network environment of this kind network card test, it mainly all is the framework of taking client end/server end (Client/Server), see through and send data via ICP/IP protocol to server-side at the client executing test program, when server-side receives client data, be returned to client then again, test with this network card transmittability of carrying out between client and the server-side.Sometimes, whether the data that client can also further relatively receive are consistent with the data that originally sent, and judge whether the data-handling capacity of network card is normal.
Yet, realize that above-mentioned test program makes the test of network card transmittability can be complete, except wanting to utilize mass data to increase pressure in the network card test process, another part is exactly to want to keep the stability of network card in test process, and the test process that sees through long-time big pressure can really be realized effectively test to network card.
Though its main cause is to keep in the network card test process providing enough lot of data to test always, but because network state all can change at any time, so-called network state changes, be meant turnaround time value (the Round Trip Time of transmitted data on network, RTT) change, network environment with Client/Server network card test transmission is an example, pass same data changing total time back by server-side again for server-side when client sees through the onesize data of Network Transmission in other words to the required use of client, when becoming big, the turnaround time value represents that it is the congested state of transmission that network is in original relatively network state, represents then that when the turnaround time, value diminished it is to transmit state smoothly that network is in original relatively network state.
Therefore, under the network environment of existing Client/Server network card test transmission, owing to lack monitoring in real time and the mechanism of dynamically adjusting, to make test program all take identical configuration parameter value to carry out test from start to finish, may be in network state and produce excessive transmission pressure when congested relatively and make network paralysis and test program interrupts can't continuing to carry out test, perhaps being in network state can't provide enough transmission pressures required data volume when smooth and easy relatively, and makes the test of test program not have an actual effect.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of network card test system and method thereof.Under the network environment of Client/Server network card test transmission in the past, increased real-time monitoring to network state, its main purpose is can be under the situation that network state changes, the real-time and dynamic adjustment is used for carrying out the configuration parameter value of the test program of test transmission, to reduce the interference effect of network state to overall network card test transmission, the configuration and the current network environment that reach test parameter can be complementary, and make test program be able to still can stablize and the correct effect of finishing the network card test transmission under the network environment that changes.
For reaching above-mentioned purpose, the disclosed network card test system of the present invention, include: dispose server-side and client respectively in order to the network card that carries out test transmission, particularly the part in client increases following program, utilizes the interworking method of these a little programs to realize monitoring in real time and dynamically adjusting network state the technical scheme of the configuration parameter value of test program:
(1) test program is carried out test program in order to the first configuration parameter group corresponding to the first network hierarchy value, and is carried out data transmission between the server-side.
Whether (2) monitoring program starts simultaneously with test program,, compare the second network hierarchy value and conform to the first network hierarchy value to the second network hierarchy value of server-side with data transmission between lasting computing and server-side in order to transmission/reception package.
(3) tactful generator, when being used to monitoring program and confirming that the second network hierarchy value differs from the first network hierarchy value, be activated the second configuration parameter group of the corresponding second network hierarchy value of dynamic generation, and supspend test, re-execute test program with the second configuration parameter group, carry out data transmission between continuation and the server-side.
Wherein, the first network hierarchy value and the second network hierarchy value are to set up the network hierarchy table in the monitoring program of client, with the turnaround time value that corresponds to different time length (Round Trip Time, RTT).And the first network hierarchy value and the second network hierarchy value are to set up the configuration parameter table in the tactful generator of client, to correspond to the first configuration parameter group and the second configuration parameter group of different parameters combination.All comprise parameter value in each parameter group in order to the size of data of setting test program, transmission intercal, transmission window size, maximum transfer unit, transmission channel number.

Embodiment
The present invention is directed to the problem that prior art exists, propose a kind of network card test system and method for being set up thereof under the network environment of Client/Server, wherein Figure 1A and Figure 1B are the running signal in the system, are described as follows:
With Figure 1A is example, network card test system 10 mainly is divided into client (computer) 100 (to call client 100 in the following text) and server-side (computer) 200 (to call server-side 200 in the following text) two parts, client 100 and server-side 200 dispose the network card 50 of pending test transmission separately, and see through network between the network card 50 of client 100 and server-side 200 and is connected with the test transmission of permission through network entity data transmission/reception.
At least include following program in the client 100, in order to the network card test transmission between leading and the server-side 200:
(1) test program 110, and the setting when being used to carry out in the amenable to process starts test program with the first configuration parameter group that is equivalent to the first network hierarchy value, carries out data transmission between beginning and the server-side 200.As existing test program, test program 110 is executed in the operating system (not shown) of client 100, mainly be that the transmission procedure (not shown) data that test transmission is required that see through network card 50 correspondences send via network card 50, the server-side 200 same network cards 50 that see through receive data and see through same channel return data to the test program 110 of client 100 then, carry out related data transmission/reception program so that carry out the analysis of follow-up other test transmission, give unnecessary details so seldom do at this at the technology contents place that the non-the present invention of the part of relevant test transmission analysis advocates.
(2) monitoring program 120, for what do not seen in the prior art, starting simultaneously with test program 110, mainly is to be responsible for monitoring state of network in test program 110 implementations, and requires tactful generator 130 to carry out the replacing of corresponding configuration parameter when network state changes really.The monitor mode of monitoring program 120 is, when reaching pre-set time interval, initiatively see through network and send package to the network card 50 of server-side 200 and be received from the package that server-side 200 is passed back via the network card 50 of client 100, turnaround time value (the Round Trip Time that utilizes package transmission/reception to be spent, RTT) continue the network state (the second promptly corresponding network hierarchy value) of computing client 100 and 200 data transmission of server-side, whether compare the second network hierarchy value conforms to the first network hierarchy value, when the second network hierarchy value does not conform to the first network hierarchy value, monitoring program 120 can be with new network hierarchy value, just the second network hierarchy value is sent in the tactful generator 130, requires tactful generator 130 to carry out the replacing of corresponding configuration parameter.
Wherein, the package that monitoring program 120 sent is for meeting the package form of Internet Protocol (IP).Establish a network hierarchy table 121 (as Fig. 2) in this external monitoring program 120, mainly be to set up corresponding between relevant heterogeneous networks grade point and the different turnaround time values, so the turnaround time value of aforementioned each package transmission/reception all can correspond to the only network grade point in the network hierarchy table.Described turnaround time value, except can be the time with each single package transmission/reception, the sum total time that also available repeatedly package is sent out/received gives average calculating afterwards and represents the average time that each package transmission/reception spent.
In fact, monitoring program 120 can also be subjected to the request of self testing procedure 110, to reply accordingly for request.For instance, test program 110 can see through request at any time and require monitoring program 120 how long once to monitor, perhaps also can require monitoring program 120 to monitor (being applied in the enforcement aspect of Figure 1B) at which server-side 200, perhaps can require monitoring program 120 to pass current network state information in real time back, as: turnaround time value, network hierarchy value ... Deng.
(3) tactful generator 130 is responsible for carrying out according to the request of monitoring program 120 renewal of configuration parameter group in the test program 110.When on behalf of the second network hierarchy value of current network state, monitoring program 120 affirmations differ from the first network hierarchy value (no matter be higher than the first network hierarchy value or be lower than the first network hierarchy value), just can give tactful generator 130 by monitoring program 120 request of sending, this moment, tactful generator 130 was activated the second configuration parameter group of the corresponding second network hierarchy value of dynamic generation, end test program 110 then, and replace the first configuration parameter group originally be used for carrying out with the second configuration parameter group, re-execute test program 110 again, continue to carry out the data transmission between client 100 and the server-side 200.Therefore, the Data transmission between tactful generator 130 and the test program 110 is mainly the new configuration parameter group corresponding to new network hierarchy value.
Certainly, also can directly see through test program 110 in realization and initiatively reply new configuration parameter group to tactful generator 130 requests, because this partly relates to the consideration of software actual design development process, can allow to be familiar with the technical staff in case of necessity and need carry out local suitable flow process adjustment, and not exclusively be confined to the exposure of the embodiment of the invention according to it.
The running of strategy generator 130 mainly is to set up a configuration parameter table 131 (as Fig. 2) therein, this configuration parameter table 131 mainly provides corresponding between network hierarchy value and the configuration parameter group, and each network hierarchy value all can correspond to unique configuration parameter group.The configuration parameter group mainly is to be used for setting the various parameter values that test program 110 is used in the test transmission process, includes: the parameter value of size of data, transmission intercal, transmission window size, maximum transfer unit, transmission channel number.
Shown in Figure 1B, can use the Client/Server network environment of network card test system of the present invention for another kind, its main difference is that the test program 110 of a client 100 can see through network simultaneously a plurality of different server-sides 200 are carried out test transmission, as for the function mode of monitoring program 120 and tactful generator 130 then with the running between aforementioned single client 100 and the single server-side 200, on its technological means with 100/ single server-side 200 runnings of single client on difference be that test program 110 is when carrying out the test transmission of different servo end 200 and monitoring program 120 at the network status monitoring of carrying out different servo end 200, the address that all needs to see through the Internet Protocol (IP) that different servo end 200 had is used as object identification, with indivedual execution different test transmission or network status monitoring program, the setting of relevant monitored object can come monitoring program 120 requests of sending to be set by test program 110 in realization.Relevant Internet Protocol (IP) the address technology contents that identification is tested as object that utilizes belongs to prior art and seldom gives unnecessary details.
The part of Fig. 2 then is that aforementioned mentioning built the network hierarchy table of putting in monitoring program 120 121 and built the configuration parameter table 131 data structure schematic diagram of putting in tactful generator 130.As shown in Figure 2, every kind of different turnaround time values (as: turnaround time value A in the network hierarchy table 121, turnaround time value B, turnaround time value C) all can correspond to different network hierarchy value (as: network hierarchy values 1, network hierarchy value 2, network hierarchy value 3), and each different network hierarchy value (as: network hierarchy value 1 in the configuration parameter table 131, network hierarchy value 2, network hierarchy value 3) all can correspond to different configuration parameter groups (as: the first configuration parameter group 132, the second configuration parameter group 133, the 3rd configuration parameter group 134), therefore the network hierarchy table 121 in the monitoring program 120 is in addition related through the network hierarchy value with building the configuration parameter table of putting in tactful generator 130 131, becomes associated data structures.Because length/weak points of 120 resulting turnaround times of monitoring program can directly be judged as the state of network congestion/smoothly, therefore the expression current network state is more congested relatively when the turnaround time value is long, the network hierarchy value that is corresponded to is lower, and the parameter value in its configuration parameter group can make test program 110 transfer to carry out the test of lower pressure relatively, so can make test program 110 stable; Otherwise the expression current network state is more smooth and easy relatively when the turnaround time value is short, the network hierarchy value that is corresponded to is higher, and the parameter value in its configuration parameter group can make test program 110 relatively then the test of execution elevated pressures, so can make test program 110 satisfy the required data pressure of test, and embody the self-adaptation of test program.
Therefore, whether really be related to test program can stablize the key of execution and just be the setting of each parameter value in the configuration parameter group in the test program 110, and parameter value as previously mentioned, please refer to the part of Fig. 3, at least can comprise: size of data, transmission intercal, transmission window size, maximum transfer unit, transmission channel number ... Deng, but be not limited thereto.The correlation general description of the pressure of these parameter values and the test program 110 network card test transmission that gives is as follows:
(1) size of data refers to the package actual size that test program 110 sends at every turn, and size of data can strengthen when the network hierarchy value is higher, and size of data need diminish when the network hierarchy value is low.For example every increase/network hierarchy value of reduction just doubles size of data or be reduced to former 1/2 size.
(2) transmission intercal refers to the packet interval time length that test program 110 sends at every turn, and can shorten blanking time when the network hierarchy value is higher, and need to elongate blanking time when the network hierarchy value is low.For example every increase/network hierarchy value of reduction just will shorten to for former 1/2 the time interval blanking time or double as the former 2 times time interval.
(3) transmission window size, employed transmission control protocol (TCP) transmission window size when referring to test program 110 transmission data is when the higher then transmission window of network hierarchy value can be bigger, when the low then transmission window of network hierarchy value need diminish.Every kind of pairing transmission window size of network hierarchy value in the practical application can utilize heterogeneous networks flow and multiplying each other of different turnaround time values to take advantage of the achievement result to decide its transmission window size.
(4) maximum transfer unit (Mez Transfer Unit), when referring to test program 110 test transmissions the maximum transfer unit size that can use, control the network fragment that this parameter value can reduce in network transmission process to be produced, this unit of transfer can be bigger when the network hierarchy value is higher, and this unit of transfer should diminish when the network hierarchy value is low.Every kind of pairing maximum transfer unit of network hierarchy value in the practical application can be the fixedly multiple of the size of data that sets in the heterogeneous networks grade point.For instance, when the data size parameters value is 64K position size, can set the size that its maximum transfer unit is 5 haplotype data sizes, i.e. 340K position size.
(5) transmission channel number refers to and can open thread (Process/Thread) number of carrying out test transmission, and this number can be bigger when the network hierarchy value is higher, and this number should diminish when the network hierarchy value is low.
Above-mentioned these parameter values, some can configure in advance for the experience set point, some parameter value is then because relevant with other parameter value or external data (as: network traffics, turnaround time value), as: transmission window size, maximum transfer unit, therefore these parameter values may generate by tactful generator 130 real-time operations in realization, need then can provide (not shown) by the part of other external data, set with the generation of finishing all parameter values in the configuration parameter group by monitoring program 120.
Fig. 4 part then is network card test method schematic flow sheet of the present invention, and operation steps basically is as follows:
Need should be mentioned that especially, confirm that in step 220 the second network hierarchy value is different with the first network hierarchy value, and when the difference grade point between both network hierarchy values had reached the predetermined threshold value that sets, tactful generator 130 of the present invention will take progressive adjustment mode to make test program from the progressive second configuration parameter group that is adjusted to of the first configuration parameter group.Give an example with Fig. 2, when the second network hierarchy value is the network hierarchy value 1 that corresponds in the configuration parameter table 131, and first network hierarchy value system corresponds to the network hierarchy value 3 in the configuration parameter table 131, it is smooth and easy to represent that then current network state has transferred toward, but because difference grade point between the two is 2 (3 subtract 1), the configuration parameter group will be adjusted to the 3rd configuration parameter group 134 by the first configuration parameter group 132 this moment, then this moment is for to avoid excessive configuration parameter adjustment will cause the running of whole test program 110 undesired, therefore tactful generator 130 can also take progressive adjustment mode slowly to adjust configuration parameter to required group, with above-mentioned example, strategy generator 130 may will be adjusted to the second configuration parameter group 133 with configuration parameter by the first configuration parameter group 132 earlier, and then be adjusted to the 3rd configuration parameter group 134 at last by the second configuration parameter group 133, finish the process of progressive adjustment configuration parameter, so the example of taking for convenience of explanation to simplify describes, but can be not limited to the description of this example in the actual progressive adjustment.
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the present invention.
