Referring to Fig. 1 and Fig. 2, the method of the real-time integrated testability of network system, its network system comprises system of inspection center and client terminal loopback responding system, wherein the system of inspection center can (comprise netting twine, optical fiber, coaxial line for server system, wired or wireless channel, route, the base station) etc., client terminal can be PC, mobile phone, other smart machine or the like, and described detection method has following steps;
1) system of test center's server operation test center, in the described test center server system of test center is set, system of described test center comprises test originating end, test receiving terminal and statistical analysis end, receiving terminal operation client terminal loopback responding system, client terminal are provided with end ring and echo and answer system;
2) network address of the client application terminal equipment that can test from the real-time or non real-time acquisition all or part of network of system of test center, as: IP, IPv6, terminal address of self-defined network or the like, and the network channel information corresponding with the network address that can test client application terminal equipment, comprise individual channel and common channel information;
3) system of test center sends the test pack that series number increases progressively by the network address of customer terminal equipment to part or all terminals, each test pack all comprises transmitting time and sends sequence number, the series of tests bag that test center sends is sent to each single terminal end of tested network, described single terminal end sequence number increases progressively and is sequence number=last sequence number+1, and described series of tests bag is sent in the client terminal system by network channel; The test pack blanking time that sends, test pack length etc. are according to user's actual demand setting.
4) the client terminal system returns the system to test center with the series of tests bag of receiving by network channel immediately one by one after receiving the series of tests bag;
5) system of test center is behind the test pack of receiving the passback of client terminal system, the recorder time is also extracted transmitting time and sequence number from test pack, test pack to all passbacks carries out following cycle detection: the calculating of time-delay, shake, again by comparing with the expectation bag, whether the test pack that detects passback is normal bag, if then record the centring system database; If improper bag detects successively according to the order of late bag, duplicate packages, out of order bag, packet loss, gained detects data and promptly generates single client terminal Back ground Information, records the centring system database.Normal bag+1 that described expectation is wrapped=received.Normally the determination methods of bag is, when receiving that bag sequence number 〉=expectation bag sequence number is, then is judged as this test pack and normally wraps, and improper bag is meant the test pack beyond the normal bag.
The test pack of passback is carried out the calculating of delay package:
The computational methods of time-delay: system of time-delay=test center receives the time of test pack time-system of the test center transmission test pack of client terminal passback.
After the test pack calculating of delaying time with passback, the calculating of shaking again:
The computational methods of described shake: the absolute value of the time-delay of the time-delay-last test pack of shake=back one test pack.
After the test pack calculating of shaking with passback, the judgement of normally wrapping:
The determination methods of described normal bag: the current bag of receiving bag sequence number 〉=current expectation bag sequence number
If current test pack is improper bag (the order-checking bag beyond the normal bag of making a comment or criticism), carry out the judgement of duplicate packages again:
Referring to Fig. 3 and Fig. 4, the determination methods of described duplicate packages is: 1) system of test center sets up and has received the interval range that sends the test pack sequence number, i.e. duplicate packages scope (needs according to the client are set in test center).Described duplicate packages scope comprises a plurality of intervals, each interval sequence number of representing the follow-on test bag that the system of test center is received.The sequence number of the follow-on test bag of receiving can be not according to sequence arrangement, but must be continuous, otherwise will set up one or several new duplicate packages scope intervals; 2) whether the sequence number of judging the test pack receive in the duplicate packages scope, if in this scope, has sequence number to repeat, and then is duplicate packages; If not in the duplicate packages scope, then set up one or several new duplicate packages scope intervals, if it is interval adjacent with existing duplicate packages scope interval to set up new duplicate packages scope, then new duplicate packages scope interval merges to existing duplicate packages scope interval, if it is non-conterminous, then set up one or several new duplicate packages scope intervals, repeat in the duplicate packages determination methods 1 again) judgement.
Usually the interval number of duplicate packages scope is many more, and the result is accurate more, but committed memory is big more, and the computing that consumes CPU is many more; The interval number of duplicate packages scope is few more, and the result is inaccurate more, but committed memory is more little, and the computing that consumes CPU is few more.Therefore, in the practical application,, can increase or reduce interval quantity, to obtain the optimal proportion of algorithm coverage and resource consumption according to the system resource situation of reality.Adopt the method that keeps the nearest several intervals of duplicate packages scope,, adjust accordingly according to resource (CPU speed, memory size) situation with the interval number of duplicate packages scope.
If current bag is duplicate packages, then this moment this test point the duplicate packages rate=duplicate packages number/sum of giving out a contract for a project.
After improper bag being carried out the judgement of duplicate packages, not duplicate packages, the judgement of the bag of then being late if ought up till now wrap:
Referring to Fig. 5, calculate with late bag threshold value, can avoid parallel delay to bring a large amount of late bag phenomenons, make test result reaction network situation more accurately.Late bag threshold value=late bag threshold time/transmissions blanking time, the threshold time of wherein being late is provided with according to client's needs.Described late determination methods: 1) set to send the blanking time of test pack and the lagged time of test pack, the blanking time by sending test pack, the lagged time with test pack was converted to late bag threshold value, whether divided late bag with described late bag threshold value; 2) deduct late bag threshold value with current expectation bag sequence number, obtain a late boundary number that wraps, the sequence number of tested bag then is late bag less than late bag boundary quantity.
If current bag is late bag, then this moment this test point late bag rate=late bag quantity/sum of giving out a contract for a project.
Improper bag is late after the judgement of bag, if current be not late bag, then carry out the judgement of out of order bag:
Receive bag if not normal bag (receiving bag sequence number 〉=expectation bag sequence number), duplicate packages, late bag, then this bag is out of order bag.
If current bag is out of order bag, then out of order bag number adds 1, and then can calculate the out of order bag rate=out of order bag number/number of giving out a contract for a project of this test point this moment.
At last to improper bag being carried out the calculating of packet loss:
The computational methods of described packet loss are: the packet loss quantity=quantity of giving out a contract for a project-normally wrap quantity-duplicate packages quantity-late bag quantity-out of order bag quantity
Can calculate the packet loss=number of dropped packets/number of giving out a contract for a project of this test point this moment.
Calculate packet loss quantity by the jump situation of receiving the bag sequence number, and when receiving non-expectation bag sequence number, the packet loss quantity of calculating is done correction, thereby obtain " current " number of dropped packets." current " number of dropped packets is done sliding window filtering get minimum value, the situation of avoiding number of dropped packets to diminish to a certain extent.
6) system of Institute of Analysis draws the state of network channel in the test period with all the client terminal test datas in the database.By obtaining single-point client state, phase-split network running status and failure judgement point position after the test to all clients.
Inspection center detects data with gained and promptly generates single client terminal Back ground Information, records the centring system database, repeats above-mentioned detection step, and inspection center all records the centring system database with all clients' of gained detection terminal-based information.
The client sets the corresponding problem limit value at each test index, surpasses the problem limit value of setting as the test result of single-spot testing index, illustrates that then this client device has problems to the network in the middle of the system of test center.For example, the limit value that the client is provided with time-delay is 1000, when the test time-delay is that 1200(is greater than 1000) time, the expression network has problem)
Test data is carried out statistical computation, get rid of interfering data (interfering data is set in test center according to client's needs), obtain network integrated testability result, if on same test path 100 applications client are arranged, test result has only 2 problem is arranged, can predicate case, get rid of network problem.
By to the path analysis of system of test center to client, decision problem point position.When the problem limit value of finding to have the target test to surpass and setting or failure when (refer to send test pack and do not return test center), the state of the test by relatively having common path (referring to no problem path) is got rid of orientation problem point position piecemeal.For example: be initiated to path G from path A and test, first path is A → B → C → F, and second path is A → B → C → D → G, after tested, first path is normally promptly normal, and second path is unusual, then A → B → C is normal common path, and problem can navigate on C → D → G path.
Pass through said method, can calculate situations such as the duplicate packages rate of the improper bag of network in running, late bag rate, out of order bag rate, packet loss, provide the quantitative target of the overall network state of operation, be convenient to network management personnel's monitoring network integrality intuitively, as whether needing to optimize network, locating network fault and be foundation such as network adjustment upgrading is with the utilization ratio that increases network with improve network running quality.
