Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, the every other embodiment that those of ordinary skill in the art are obtained belongs to present invention protection
Scope.
A kind of embodiments in accordance with the present invention, there is provided method of testing of line card.
As shown in figure 1, the method for testing of line card according to embodiments of the present invention includes：
Step S101, according to the type of network interface of line card, configures to predetermined common template, generates map network
The actuation generator of interface type, wherein, the excitation comprising correspondence multiple network interface type in predetermined common template occurs
The general character content of device；
Step S103, will send to desired value maker and line with the target excitation produced by the actuation generator for postponing
Card；
Step S105, desired value maker and line card are respectively calculated by identical pre-defined algorithm to target excitation,
Obtain the first result of calculation of respective desired values maker and the second result of calculation of correspondence line card and export；
Step S107, the first result of calculation and the second result of calculation are contrasted, and are different situations in comparing result
Under, determine line card exception.
Wherein, it is consistent with due to the function that the line card that different network type is accessed is realized, then correspond to integrated survey
In examination platform, simply driving source is different, and most basic unit is all IP messages, in the present embodiment using encouraging base board unit
Identical the characteristics of, as shown in figure 1, a basic_calss (a kind of empty class) is constructed in the present embodiment, wherein, empty class
Comprising correspondence multiple network interface type (here including existing popular thousand in basic_class (i.e. common template)
Mbit ethernet interface, ten thousand mbit ethernet interfaces, 2.5GPOS interfaces, 10GPOS interfaces) actuation generator general character content (example
Such as the method for the attribute and treatment IP messages of basic IP messages), then in this example figure it is seen that the present embodiment is to upper
The network interface for stating four types has carried out the realization of common template, i.e. according to the type of network interface of line card, to basic_
Class is configured, so that the actuation generator of map network interface type is generated, specifically, figure it is seen that this reality
Apply example using to empty class basic_class inherit by the way of realize gigabit ethernet interface, ten thousand mbit ethernet interfaces,
Four actuation generators of 2.5GPOS interfaces, 10GPOS interfaces, respectively pos_class, 10pos_class, ge_class,
xge_class；
Wherein, when being inherited to basic_class, can be according to the type of interface to the attribute of IP messages, such as five
Tuple (source IP address, purpose IP address, source port, destination interface, agreement), message length；And the method for the treatment of IP messages,
For example set and obtain the methods such as IP message products degree, load, five-tuple carries out configuration realization respectively.
Additionally, in one embodiment, because the interface of different network type there may be some specific functions, because
This, method of testing according to embodiments of the present invention may also include：
According to the type of network interface of line card, predetermined privately owned template is configured, wherein, the initial shape of privately owned template
State is space state, and its actuation generator for being used to storing map network interface type is different from the type of other network interfaces
The difference content of actuation generator, for example, be specifically different from member and the method for other types interface.
So after the type of the network interface according to line card is to common template and privately owned template configuration, so that it may using configuration
The actuation generator for being formed afterwards is tested the line card of different interface type, and Fig. 3 then shows specific testing process, from
The test platform that Fig. 3 can be seen that in the present embodiment includes actuation generator, excitation driver, expected result maker
(desired value maker), response monitor, detector, log generator, specific mode of operation are as follows：

Kind or it is various, and encourage the member (that is, encourage) can be produced while actuation generator is configured and completed, (i.e. target is sharp for excitation
Encourage, it can also be multiple that can be one) while produce, system can set up expectation queue, and be the target excitation point for producing
With its address in queue is expected, address information is then allocated to the target excitation, configuration mode here is by address
Information is added in the middle of target excitation as label, and then system can be stored in pond is encouraged tagged target excitation,
Meanwhile, also target excitation can be stored according to the label for the relevant position in queue is expected；
Then, excitation driver will obtain data (i.e. target excitation, it is notable that subsequently carry from excitation pond
To target excitation be with label), and tested line card (being tested design) is sent to by bus functional model, in this
At the same time, it is desirable to being worth maker can also obtain driving source as pass devices, i.e., obtain target excitation from excitation pond；
Then obtain target excitation tested line card and desired value maker can use identical algorithm to obtain mesh
Mark excitation calculated, will obtain respective desired values maker the first result of calculation (desired value) and correspondingly line card second
Result of calculation (end value)；
Wherein, label information of the desired value that desired value maker will will be calculated in the target excitation is in the phase
Hope in queue and search the corresponding queue position of the target excitation, then by desired value storage in the queue position；
And the end value and the target excitation with label that tested line card will can then be calculated send to response and monitor
Device, is then responding to monitor and is stored to corresponding the end value and target excitation with label by bus functional model
In response queue, and detector can then obtain the target excitation and end value from the response queue, and it is sharp to read out the target
The label encouraged, then determines the position of the target excitation according to the label in queue is expected, then the phase from queue is expected
The desired value that the target excitation is obtained at position is answered, then the desired value and end value of acquisition is contrasted, comparing result is then
By log generator generation information correctly or incorrectly, wherein, if comparing result is different for the two, generation is tested line card
Abnormal information；And if in the case of comparing result identicals for both, then generating the normal information of tested line card, with regard to this realization
To the integration testing of the safety product of multi input interface type.
