Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.
Please refer to Fig. 1, the method for testing basic procedure schematic diagram of a kind of communication equipment veneer that the embodiment of the invention provides.This method mainly comprises step:
S101 reads the message configuration attribute, generates test packet according to this message configuration attribute.
For convenience of description, the message of the embodiment of the invention is assumed to be the Ethernet message, but it will be understood by those skilled in the art that the message of the embodiment of the invention is not limited to the Ethernet message, can also be other messages such as ATM message, P2P protocol massages.The typical Ethernet message format that present embodiment provides comprises Ethernet heading, IP heading and message payload (Payload) as shown in Figure 2.Wherein, the message payload can also comprise some check field.In embodiments of the present invention, can be configured IP heading and message payload check field in advance, the message configuration attribute that forms after these configurations is stored in the memory.When the test beginning, from memory, read these message configuration attributes, thereby generate test packet according to described message configuration attribute.Owing to can dispose different message configuration attributes according to actual needs, therefore, the test packet that generates also can be varied, can simulate the message in the real network environment better, is not limited to several test packets that tester can produce in the prior art method of testing.
For example, shown in Figure 3 is the form of a classical ip heading in the present embodiment, comprises IP message length field, source IP field, purpose IP field, IP heading protocol number field, field offset field and type of service field etc.In embodiments of the present invention, can be configured IP message length field.For example, IP message length field configuration can be become fixed length, elongated, random-length or overlength, be used to generate fixed length message, elongated message, random-length message or overlength message.Especially, for being configured to the overlength message, for example, the message of 1500 bytes, standard ethernet protocol is not supported, but many proprietary protocols are all supported, therefore, than tester of the prior art, present embodiment aspect the test packet that can generate all lengths is being a breakthrough, by reading for example IP message length field of message configuration attribute, can generate the test packet of all lengths, thereby the limit test that the tester that can finish prior art can not be finished (for example, to length being the test of this class overlength message of 1500 bytes).
The tester of prior art can only be tested limited several standard agreement messages, but in embodiments of the present invention, can be configured IP heading protocol number field, message after the configuration can also be supported the test of other more nonstandard protocol messages such as proprietary protocol except the test that can support working standard protocol massages such as TCP, UDP or TELNET.
In order to guarantee to discern in the subsequent processes alignment processing message of test packet, in embodiments of the present invention, can the message payload check field (as shown in Figure 2) in the message payload be configured.Particularly, can the magic field in the message payload check field be configured.Magic field (magic num) is equivalent to an identification field, what adopt between the veneer of communication equipment in the present embodiment is common bus communication, testing equipment for example coffret plate can be received non-test packet, the magic field (for example is configured to a fixed value, 0x5a7e), can be used to distinguish a message is that test packet also is non-test packet,, can be used to judge whether message is test packet after disposing this field that is.
Because after tested veneer receives test packet in the present embodiment, can handle formation to test packet and handle message, and will handle message and return to testing equipment, so can also utilize the magic field to judge whether message is the processing message that forms based on test packet in the present embodiment.
For test or checking prediction message whether whether payload (Payload) out of order or message makes mistakes in network transmission process, in embodiments of the present invention, can also be configured other field (as shown in Figure 2) in the message payload check field, for example, the configuration of test serial number field, the configuration of CRC check field and at least one in the stream index field are configured etc.; Particularly, when configuration, can dispose above-mentioned message payload check field at message payload section start.It is as follows relevant field in the verification of above-mentioned message payload to be done brief description herein.
The test serial number field is a sequence number that is that each test packet that sends distributes, and its numerical value increases progressively according to the sequence number that sends, and disposes whether be used for the verification test message after this field out of order in the transmission of network; Particularly, receiving terminal can judge whether the transmission of test packet in network be out of order according to the test serial number that receives.
The CRC check field, i.e. whether cyclic redundancy check field is done the CRC protection to payload, be used for checking the payload of message to be modified when network transmits after disposing this field; Particularly, receiving terminal can judge whether the payload of message is modified according to the CRC check field in network transmission process.
The stream index field is used for the configuration list item that data query flows after the configuration; Particularly, receiving terminal can be inquired about according to the configuration list item that flows according to the stream index field, and data flow is made of a plurality of messages that transmit in network, has precedence relationship between these messages.
Can understand, in order to produce a greater variety of messages or to reach more test purposes, can also carry out various configurations to IP heading or message payload check field, also can increase the project of configuration, above-mentioned configuration just is used for of the present invention illustrating, and is not limited to the present invention.
By flexible configuration to message attribute, not only can as tester in the prior art, generate messages commonly used such as UDP message stream, tcp data stream, Ping message, ARP message and IP fragmentation message, can also generate such as a verification misrepresent deliberately literary composition, various exception messages such as literary composition, out of order message, overlength message and proprietary protocol message are misrepresented deliberately in the verification of TCP payload.
S102 is sent to tested veneer with test packet.
Generate after the test packet, can be further to test packet resolve, route analysis, traffic shaping (TS, Traffic Shaping) and operation such as queue management, be sent to tested veneer then, wherein packet parsing, route analysis, TS and queue management etc. are similar with prior art or identical, do not do herein and give unnecessary details.
S103 judges whether the message that receives is that test packet is handled the processing message that the back forms through tested veneer, if then this processing message is tested and obtain assay.
Tested veneer can be back to testing tool (being testing equipment) after test packet is handled, for example, be back to coffret plate of using as testing tool etc., yet, as previously mentioned, because what adopt between the veneer of communication equipment is common bus communication, concerning the coffret plate, also may receive non-test packet.Therefore, in embodiments of the present invention, whether the coffret plate of using as testing tool need be that the processing message that forms and return after test packet is handled through tested veneer is judged to the message that receives.
Because tested veneer is when handling test packet in the present embodiment, can not change and wherein be used to (for example identify this message, identifying this message is that test packet also is non-test packet) identification field, therefore, when the coffret plate of using as testing tool is judged, can check certain identification field in the message that receives, if the value of this identification field is identical with the value of corresponding identification field in the test packet that sends, judge that then the message that receives is the processing message that forms and return after test packet is handled through tested veneer.
As one embodiment of the invention, test packet is being handled in the process that forms the processing message, can't make amendment to the payload part of test packet, that is to say that handling message compares with test packet, payload part can not change, thereby the magic field in the payload can not change yet, can test to the magic field in the message payload, if its value be the Configuration Values of test packet when sending (for example, 0x5a7e), judge that then the message of receiving is the processing message that forms and return after test packet is handled through tested veneer, otherwise, judge that the message of receiving is not the processing message that forms and return after test packet is handled through tested veneer, further, can also abandon the message of receiving.
Test packet and processing message are corresponding mutually in the present embodiment, for example a test packet is handled the back through tested veneer and is formed a processing message, this processing message is compared with test packet, and payload part (comprising message payload check field) remains unchanged.
Test and to comprise handling message in the present embodiment: the CRC check field that the processing message comprises is carried out verification,, then send error messages if make mistakes.Whether the CRC check field is carried out verification is to be modified when transmitting in network for the payload (comprising the payload check field) of judging message, if change, then thinks and makes mistakes.Makeing mistakes to occur in the transmission course of test packet, also may occur in the transmission course of handling message.If not change thinks that then the transmission of test packet and the transmission of processing message all do not make mistakes.
Perhaps test and to comprise: read adjacent two test serial number fields of handling message, obtain described adjacent two test serial numbers of handling message handling message; Calculate the poor of described adjacent two test serial numbers of handling messages, if described difference is greater than predetermined value, judge that then the transmission of test packet in network is out of order, it is out of order perhaps to handle the transmission of message in network, perhaps the transmission of the transmission of test packet and processing message all takes place out of order, promptly judge test packet in network transmission and handle the transmission of message in network at least one be out of order in the two, and send out wrong message.Adjacent two processing messages refer to that testing equipment receives when handling message the adjacent processing message that receives in the present embodiment.Be understandable that because Network Transmission may cause the out of order of message, the order the when order between the adjacent processing message that testing equipment receives might not send these processing messages with tested veneer is identical.
Wherein read adjacent two test serial number fields of handling message, obtaining described adjacent two test serial numbers of handling messages can be in the following way: for example can read a test serial number field in the payload of handling message, obtain the test serial number of this processing message; Inquire about the message configuration attribute table of this processing message according to the stream index field that this processing message comprises, thereby read the test serial number field of previous processing message, obtain the test serial number of this previous processing message.Perhaps can take alternate manner, the embodiment of the invention does not limit this yet.For example receive one handle message after, read the test serial number field in the payload of this processings message, and receive next handle message after, read the test serial number field of this next one processing message.
As an optional embodiment, can be after the transmission that makeing mistakes and handling message of finding test packet according to the CRC check field all make mistakes yet, again the check test message in network transmission and the transmission of processing message in network in whether occur out of order.Concrete deterministic process can no longer describe in detail referring to the foregoing description herein.
S104, the assay of statistic procedure S103, and according to statistics generation test report.
In below assay can comprise at least one: test packet in network transmission and handle the transmission of message in network whether payload changed (promptly whether makeing mistakes); Whether transmission and processing message the transmission in network of test packet in network be out of order.
Further, assay can also comprise through occurring the wrong number of times and/or the number of the correct processing message that receives after the CRC check.
In addition, present embodiment can also further be added up the test packet that sends when adding up, and comprises the test packet number that sends and the statistics of byte number; Statistical can comprise the tabulate statistics that sends according to type of message statistics, according to each data flow experience different transmission path and at the statistics respectively of every veneer etc.
In addition, present embodiment can also be further be added up the processing message that receives when adding up, and comprises at each statistics of handling message byte number etc. for example, the processing message number that receives etc.; Statistical comprises according to returning the harden tabulate statistics of fruit and at the statistics respectively of every tested veneer etc. of coffret after each data flow experience different transmission path.
In addition, can also and handle the message number according to the test packet number, whether statistics packet loss takes place, and for example on each data flow whether packet loss takes place, and between every tested veneer and the coffret plate whether packet loss takes place.
Testing equipment can for example be handled message to message automatically and test after receiving the processing message in the present embodiment, and generates test report according to assay.
From the invention described above embodiment as can be known, by configuration to message attribute, can generate different test packets, therefore, with prior art use test instrument system is tested and to compare, the present invention not only can realize (for example, the proprietary protocol message) the test, and can realizing comprising the test of exception messages such as overlength message, out of order message, payload check errors of some nonstandard protocol messages.Because exception message more can the changeable real network environment of Simulation of Complex, therefore, the problem that method of testing of the present invention occurs in the time of more testing out the actual operation of network, the test result that obtains is reliable more, truly; Meanwhile, the method for testing whole test process automation that the embodiment of the invention provides does not need manual intervention, therefore, has reduced the dependence to tester's technology or experience yet, and the test result that draws is more objective.
See also Fig. 4, the testing equipment that the embodiment of the invention provides is coffret plate basic structure schematic diagram for example.For convenience of explanation, only show the part relevant with the embodiment of the invention.
Usually, the coffret plate provides the communication system external interface, finishes message and receives, sends, transmits, separates functions such as frame/framing and scheduling, handles various host-host protocols.In embodiments of the present invention, the coffret plate also comprises message generation module 401, judge module 404, inspection module 405 and statistical module 406 except comprising sending module 402 and receiver module 403.

In this enforcement, the message configuration attribute comprises configuration of IP heading and the configuration of message payload check field, wherein:
The configuration of IP heading comprises the configuration of IP message length and the configuration of IP heading protocol number, is used to generate the message of all lengths after the IP message length field configuration, is used to support various protocols after the IP heading protocol number field configuration, comprises proprietary protocol;
The configuration of message payload check field comprises the configuration of magic field in the message payload, behind 404 pairs of magic field checkings of judge module, can judge whether the message that receiver module 403 is received is the processing message that forms and return after test packet is handled through tested veneer;
Further, in the present embodiment, message payload check field configuration can also comprise at least one in the configuration of the configuration of configuration, CRC check field of test serial number field and stream index field; Wherein:
Whether be used for the verification test message after the test serial number field configuration out of order in the transmission of network;
Whether the payload that is used for the verification test message after the CRC check field configuration is modified when network transmits;
Be used for configuration list item after the stream index field configuration at receiving terminal data query stream
By configuration to IP heading and message payload check field, (for example not only can realize some nonstandard protocol messages, the proprietary protocol message) test, and can realize comprising the test of exception messages such as overlength message, out of order message, payload check errors.Because exception message more can the changeable real network environment of Simulation of Complex, therefore, the problem of appearance when the coffret plate that the embodiment of the invention provides more can test out the actual operation of network.
The judge module 404 of Fig. 4 example can comprise first judging unit 501, as shown in Figure 5 the another kind of testing equipment (for example, coffret plate etc.) that provides of the embodiment of the invention.First judging unit 501 is used for the value of the message magic field that receives according to receiver module 403, judges whether the message of receiving is that test packet is handled the processing message that the back forms through tested veneer.
The inspection module 405 of Fig. 4 or Fig. 5 example can comprise CRC check unit 601, as shown in Figure 6 another testing equipment (for example, coffret plate etc.) of providing of the embodiment of the invention.CRC check unit 601 is used for the CRC check field that the processing message comprises is carried out verification, if make mistakes, then sends error messages.

Reading unit 701 reads the test serial number field of adjacent two test packets, obtains the test serial number of these adjacent two test packets;
Particularly, computing unit 702 calculates the test serial number field of test packets and the difference of the test serial number field of the previous test packet of this test packet, as if this difference greater than a predetermined value, for example 2
31-1, then second judging unit 703 judges that the transmission of test packet in network is out of order, it is out of order perhaps to handle the transmission of message in network, perhaps the transmission of the transmission of test packet and processing message all takes place out of order, promptly judge test packet in network transmission and handle the transmission of message in network at least one be out of order in the two, and send out wrong message.Adjacent two processing messages refer to that testing equipment receives when handling message the adjacent processing message that receives in the present embodiment.Be understandable that because Network Transmission may cause the out of order of message, the order the when order between the adjacent processing message that testing equipment receives might not send these processing messages with tested veneer is identical.
For reading unit 701, it obtains adjacent two test serial numbers of handling messages can be in the following way: for example can read a test serial number field in the payload of handling message, obtain the test serial number of this processing message; Inquire about the message configuration attribute table of this processing message according to the stream index field that this processing message comprises, thereby read the test serial number field of previous processing message, obtain the test serial number of this previous processing message.Perhaps can take alternate manner, the embodiment of the invention does not limit this yet.For example receive one handle message after, read the test serial number field in the payload of this processings message, and receive next handle message after, read the test serial number field of this next one processing message.
For example, if computing unit 702 calculates the difference of test serial number field of previous test packet of the test serial number field of test packets and this test packet greater than 2
31-1, judge that then the transmission of test packet in network is out of order, send error messages, it is basic according to being: network congestion may cause test packet to be lost in transmission, thereby causes test serial number discontinuous but be unlikely to out of order; If the absolute difference of two test serial numbers receiving has continuously surpassed test serial number maximum 2
32Half because test serial number produces by 32 (bit) binary codings, do not have the situation that licks head in the reality, only understand by message out of order and introduce in transmission course.Therefore, when the difference of the test serial number field of the previous test packet of the test serial number field of test packet and this test packet greater than 2
31, think that the transmission of this test packet in network is out of order at-1 o'clock.
The functional module that the coffret plate of the invention described above embodiment comprises all is programmable, (for example not only can realize some nonstandard protocol messages, the proprietary protocol message) test, and can realize comprising the test of exception messages such as overlength message, out of order message, payload check errors.Because exception message more can the changeable real network environment of Simulation of Complex, therefore, the coffret plate that the embodiment of the invention provides more can test out the problem that occurs when network is actual to be runed, simultaneously, the coffret plate that the embodiment of the invention provides makes the whole test process automation, reduced dependence to tester's technology or experience, and, than the tester of prior art costliness, the programmability of the coffret plate functional module that the embodiment of the invention provides makes that also testing cost reduces greatly.
