Specific embodiment

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 Whole description, it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.It is based on Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made Embodiment, belongs to the scope of protection of the invention.

Virtual network operator can provide private leased circuit service for client, will be with the network channel of fixed-bandwidth (claiming bandwidth) Distribute to client, but whether the bandwidth (actual bandwidth) that can actually use of the special line of distribution can reach which and bandwidth is claimed, Need to test the bandwidth of special line, to determine the actual bandwidth scope of special line.

Traditional approach using the offer under RFC2544/Y.1564 (being communication standard protocol) method of testing testing The actual bandwidth scope of special line, by two equipment on a special line, using one as the equipment of transmission, another is used as reflection Equipment, transmission equipment can be dependent on the quantity of the message sent to reflecting device, and the report for receiving reflecting device return The quantity of text calculates packet loss, and the concrete numerical value according to packet loss completes bandwidth test.

It can be seen that, current bandwidth test mode is in one-way channel (the such as up channel or descending letter for testing a special line Road) bandwidth when, need to use the bandwidth of two one-way channels, if it is special to the channel direction of reflecting device for example to send equipment During the up channel of line, then reflecting device needs the bandwidth of the down channel for using special line when reflecting message to transmission equipment. But for dissymmetric network, the up channel of special line and the bandwidth value of down channel and differ, if sending out in the method for testing The corresponding first rate of the bandwidth of sending equipment to be dependent on up channel sends message, but the bandwidth of down channel is less than up letter During road bandwidth, it is known that the corresponding first rate of the bandwidth of up channel second speed corresponding with the bandwidth of down channel is different, Although reflecting device needs to return, to transmission equipment, the message that receives by the first rate, but the bandwidth of down channel institute Supported is the message transmissions under the second speed, then reflecting device on the downlink channel cannot be smooth by first rate possibly The return of message is realized, although cause reflecting device to be successfully received message and reflected message to transmission equipment, by In the restriction of downstream channel bandwidth, reflecting device can only abandon the message being successfully received in a large number, by segment message with the second speed Rate is reflected, and can only calculate abnormal packet loss so as to send equipment, it is clear that cannot function as to the special line up channel The foundation of bandwidth measurement.It can be seen that, for this dissymmetric network, traditional approach determines that the packet loss of one-way channel is very possible It is incorrect, so as to can not accurately measure the relevant parameter of the one-way channel bandwidth of special line.

For this purpose, a kind of method and apparatus of bandwidth test is embodiments provided, before bandwidth test is started, specially The transmission equipment in two equipment on line sends the survey for carrying bandwidth test start time and finish time to receiving device When examination information so that when receiving device clear and definite can begin for test packet is counted, terminate to count, and completes to survey After the transmission of examination message, transmission equipment is it is also possible that the test packet sum for sending issues receiving device so that receiving device Packet loss can be calculated in conjunction with the received test packet sum of statistics, and transmission equipment is supplied to, the equipment of transmission can root Bandwidth test is completed according to the concrete numerical value of packet loss.It can be seen that this bandwidth test mode is independent of from receiving device to transmission equipment Channel width, effectively can carry out bandwidth test for one-way channel in dissymmetric network.

It is additionally, since transmission equipment and can gets test result i.e. packet loss, therefore transmission equipment can be according to loses The size of bag rate judges whether to need to re-start bandwidth test, such that it is able to when needing to retest, send equipment permissible The transmission rate of bandwidth test is voluntarily adjusted according to packet loss, it is achieved that the automation of bandwidth test, improve bandwidth test Efficiency.

The embodiment of the present invention is mainly used in the equipment on special line, as shown in figure 1, for two equipment being applied on special line Schematic diagram, respectively send equipment and receiving device, for carrying out bandwidth test to special line, it is generally the case that implement this The mode provided by inventive embodiments can test the bandwidth of an one-way channel in special line, and one-way channel described here is permissible For the up channel in special line or down channel.

The transmission equipment proposed by the embodiment of the present invention and receiving device are the equipment on special line, wherein, send equipment Can be that receiving device can be reported for receiving test in bandwidth test for sending the equipment of test packet in bandwidth test The equipment of text.For example, the device A on a special line and equipment B, when need test special line on from device A to the unidirectional letter of equipment B During the bandwidth in road, from device A to equipment B send test packet, now device A i.e. equivalent to send equipment, equipment B i.e. equivalent to Receiving device；When the bandwidth for needing to test the one-way channel on special line from equipment B to device A, sent from equipment B to device A Test packet, now, i.e. equivalent to the equipment of transmission, device A is i.e. equivalent to receiving device for equipment B.Transmission equipment and receiving device master To be the network equipment of Virtual network operator side, can be edge device (the such as Virtual network operator side of Virtual network operator business Boundary's router).Transmission equipment and receiving device can be specifically the equipment such as switch, router and optical module.

The method and apparatus of bandwidth test provided in an embodiment of the present invention, can apply in business Acceptance Test (Service Acceptance Test, SAT) stage, for example, when Virtual network operator opens enterprise's special line according to enterprise demand, in order to determine Whether the bandwidth of distribution special line can meet the demand of enterprise, can be provided using the embodiment of the present invention when enterprise's special line is opened The method of bandwidth test the bandwidth of the special line is tested.The method of bandwidth test provided in an embodiment of the present invention and dress Put, it is also possible to which the bandwidth of the special line to coming into operation is tested, for example, client is mounted with down channel for the special of 10M bandwidth Line, the speed that sensory data is downloaded in use do not reach the speed that 10M bandwidth should reach, and Virtual network operator can lead to The method for crossing bandwidth test provided in an embodiment of the present invention, the downstream channel bandwidth for testing the special line are specially how many, if reach To 10M.

Embodiment one

Next, the method that the bandwidth test provided by the embodiment of the present invention is discussed in detail.Fig. 2 is carried for the embodiment of the present invention For a kind of bandwidth test method flow chart, two equipment being applied on special line, described two equipment include that transmission sets Standby and receiving device, the method include：

S201：The transmission equipment sends test information, the test information by the special line to the receiving device Start time and finish time including bandwidth test.

Special line can be the network channel with fixed-bandwidth that Virtual network operator distributes to client, for example, asymmetric Under network, client needs down channel for 10M bandwidth, and up channel is the special line of 5M bandwidth, and Virtual network operator can be according to visitor The demand at family distributes the network channel with corresponding bandwidth for client, and the network channel is what Virtual network operator was provided for client Special line, the bandwidth that is distributed are used alone by the client, and client can realize the transmission of data by the special line.Or, should Special line can also be the up-downgoing channel width identical special line under symmetrical network, and such as up channel and down channel are The special line of 10M bandwidth.In implementing, Virtual network operator can be dependent on service-level agreement (Service-Level Agreement, SLA) to client, special line is set.

, in the quantity of statistical test message, the quantity counted under the unified time period is just for transmission equipment and receiving device With comparativity, so as to ensure to carry out test packet quantity under the accuracy of the packet loss for calculating, and unified time period Statistics, it is ensured that the real-time of transmission, the packet loss for thus calculating can more accurately reflect the actual biography of special line Defeated speed.So, before bandwidth test is carried out, sending equipment and being sent to receiving device by special line includes bandwidth test Start time and finish time test information.

Start time can be used to indicate that transmission equipment starts to send the moment of test packet, finish time to receiving device Can be used to indicate that transmission equipment stops sending the moment of test packet to receiving device.

S202：The receiving device obtains the test information that the transmission equipment sends.

The start time for carrying bandwidth test sent by reception transmission equipment and the test information of finish time, Receiving device according to bandwidth test start time clearly from when starting to count test packet, according to bandwidth test When finish time is clearly from terminating the counting to test packet.For example, generally can carry transmission to set in test packet Preparation gives the timestamp during test packet, and receiving device can count the timestamp for receiving more than or equal to the start time Test packet quantity, when test packet timestamp beyond the finish time when complete the counting to test packet.

S203：The transmission equipment was sent to the receiving device according to set rate and surveys from the start time Examination message is till the finish time.

The type of test packet described here can include the species of message, for example, UDP (User Datagram Protocol, UDP) type is UDP message, transmission control protocol (Transmission Control Protocol, TCP) type is TCP message etc..Feature or feature that the type of test packet can also have including message, Destination address, source address as message etc., can specifically include specific source MAC and target MAC (Media Access Control) address, or specific Source IP address and purpose IP address, or source port number and the destination slogan of TCP/UDP message, or particular mac address, Combination of the port numbers of IP address and TCP/UDP message etc..When the message with this feature or feature can both be identified the survey Examination message.

Test packet could be for testing the message used by special line bandwidth, and the length of test packet can be dependent on reality Border demand is set, and the embodiment of the present invention is not limited to which.Transmission equipment and receiving device can be before bandwidth tests The type of test packet is specified, such transmission equipment can clearly send which type of message as test packet, and reception sets Standby can identify that received which type of message is that receiving device can be known for the message of bandwidth is tested, in other words It is the message for needing statistical magnitude not go out which type of message.

In embodiments of the present invention, bandwidth can be used to indicate that the data transmission capabilities that special line can be provided by, transfer rate Data volume of the special line in transmitted per unit time is can be used to indicate that, the unit of bandwidth can be million (M), it is generally the case that 1M Bandwidth, its corresponding speed can be 128KB/s.Virtual network operator for client distribute special line when, according to the list of the special line Claim that bandwidth can calculate the corresponding transfer rate of the one-way channel to channel.For example, Virtual network operator distributes for client The bandwidth of an one-way channel of special line claim and can reach 10M, it is generally the case that the bandwidth of 10M, its corresponding transmission speed Rate can be 1280KB/s.

Set rate refers to send the transmission rate adopted by test packet, the band that can be tested according to needed for bandwidth test Width is calculated corresponding speed, and it is 10M for example to need the bandwidth that tests, then the set rate determined according to the bandwidth can Think 1280KB/s.The bandwidth of required test can be obtained according to the bandwidth determination claimed by the one-way channel of special line, it is also possible to The bandwidth determination that is tested during according to last bandwidth test is obtained.

The present invention does not limit the concrete mode of bandwidth test, for example, carry out bandwidth survey in an one-way channel to special line During examination, the bandwidth that can be claimed first by this one-way channel is determined according to the bandwidth pre- as the bandwidth of required test Constant speed rate is tested, if packet loss is higher, the bandwidth of test needed for being adjusted by packet loss, and for example turn down certain Degree, the bandwidth after then proceeding to according to adjustment carry out bandwidth test, if packet loss relatively low even without, it is also possible to by losing Bag rate is for example heightened to a certain degree come the bandwidth of test needed for adjusting, and the bandwidth after then proceeding to adjustment proceeds bandwidth Test.By the bandwidth of test needed for constantly adjustment, the actual bandwidth higher limit of this one-way channel can be finally given.This Bandwidth test proposed in inventive embodiments can be understood as being arbitrarily once directed in above-mentioned complete bandwidth test process to be had The bandwidth test that body bandwidth is carried out.

S204：The receiving device carried out counting to get the second count value, second count value from the start time For the test packet sum that the receiving device is received from the start time to the finish time from the transmission equipment.

Transmission equipment starts to send test packet to receiving device from the beginning of time, due to receiving device in advance clearly The start time of bandwidth test is how many, therefore the number of the test packet that receiving device can be in start time to receiving enters Row statistics, is carved into when reaching when finished, and transmission equipment stops sending test packet to receiving device, and now receiving device also stops Count, be carved in section this period finish time from the outset, the number of the test packet of receiving device statistics is from transmission The sum of the test packet that equipment is received, can be using the sum as the second count value.

It should be noted that S203 and S204 have no the restriction on sequencing, two steps can be carried out simultaneously, from opening Moment beginning starts transmission equipment and sends test packet to receiving device, and receiving device starts to count the test packet for receiving.

S205：The transmission equipment sends the first count value to the receiving device, and first count value is described The test packet sum for sending equipment to send from the start time to finish time to the receiving device.

Transmission equipment starts to send test packet to receiving device from the beginning of time, stops sending test report to finish time Text, the sum for being carved into the test packet that transmission equipment is sent to receiving device in the time period of finish time from the outset can be made For the first count value.

The determination mode of the first count value can have multiple, can by send device statistics draw the first count value, for example, Send device statistics to be carved in the time period of finish time from the outset, the number of the test packet sent to receiving device, system The number that counts out is the first count value.First count value can also be calculated by transmission equipment, and generally, transmission sets For when under set rate to receiving device transmission test packet, the number of the test packet of transmission equipment transmission per second can be Changeless, the time for being carved into finish time experience from the outset is dependent on, transmission equipment can be calculated from the beginning of time The sum of the test packet sent to receiving device to finish time, for example, sends that equipment is per second can send to receiving device Test packet number be 10, that is, send equipment send test packet number speed be 10/second, be carved into knot from the outset The time of bundle moment experience is 100 seconds, then send the test report that equipment is carved into finish time from the outset and sends to receiving device Sum, i.e. first count value of text is 10*100=1000.The embodiment of the present invention is not done to the determination mode of the first count value Limit.

S206：The receiving device obtains the first count value that the transmission equipment sends.

In embodiments of the present invention, can be dependent on the first count value and the second count value carries out the calculating of packet loss, by It is to be drawn by different device statisticses respectively in the first count value and the second count value, when the calculating for needing to carry out packet loss, Need the two count values to be got by same equipment, then lost according to the first count value and the calculating of the second count value by the equipment Bag rate.In the present embodiment, the first count value can be sent to receiving device by transmission equipment, carry out packet loss by receiving device Calculating.

Transmission equipment sends the sending method of the first count value to receiving device, and the embodiment of the present invention is not limited, permissible Be finish time reach after, transmission equipment directly by the first count value that determines be sent to receiving device, or by The message for the first count value of acquisition request that receiving device is sent to the equipment of transmission, sends equipment upon receiving the message First count value is sent to receiving device.

S207：The receiving device calculates the packet loss of the bandwidth test according to the first count value and second count value Rate.

Packet loss can be used to indicate that the quantity of the test packet that loses in bandwidth test is total in the transmission of test packet Shared ratio in amount.Packet loss can explicitly indicate that the bearing capacity of channel, when packet loss is too high, represents and send test report The set rate of text, represents at the set rate for sending test packet when packet loss is relatively low beyond the bearing capacity of channel Among the bearing capacity of channel.In embodiments of the present invention, the transmission total amount of test packet can be transmission equipment to reception Quantity, i.e. first count value of the test packet that equipment sends.The quantity of the test packet of loss can be sent by the equipment of transmission The quantity of test packet deduct quantity, i.e. first count value of the test packet that receiving device is received with the second count value Difference.Packet loss can be represented by the form of decimal or percentage that a kind of specific computational methods can first calculate first Count value and the difference of the second count value, the difference are counted divided by first and are worth to a numerical value, and the numerical value is packet loss, The numerical value is multiplied by 100% form that can be converted to percentage.For example, when bandwidth test is carried out, in stipulated time section Interior, the sum of the test packet that the equipment of transmission is sent to receiving device is 1000, and receiving device receives the transmission of transmission equipment Test packet sum be 980, then packet loss can be (1000-980)/1000=0.02, packet loss can also be with hundred Fractional form represents, i.e. 0.02*100%=2%.

S208：The receiving device sends the packet loss to the transmission equipment.

Transmission equipment is the originating end of bandwidth test, and transmission equipment can be dependent on the concrete numerical value of packet loss and judge this Whether the bandwidth that is tested in bandwidth test can represent the actual bandwidth of special line one-way channel.Therefore, receive in S207 and set For after calculating packet loss, the packet loss is sent to receiving device by needs.

As receiving device is only that the packet loss for calculating is sent to transmission equipment, can't take from receiving device to The bandwidth of the one-way channel in this direction of transmission equipment, that is to say, that for dissymmetric network, the transmission process will not be subject to from Receiving device is to the impact of the speed of the one-way channel in this direction of transmission equipment, therefore can effectively be applied to dissymmetric network The bandwidth test of middle special line.

S209：The transmission equipment obtains the packet loss of the bandwidth test from the receiving device.

When carrying out bandwidth test to an one-way channel of special line, packet loss sends test with the equipment of transmission to receiving device Set rate during message is relevant, and in S203, the bandwidth calculation that is tested according to needed for bandwidth test obtains corresponding speed, The set rate of test packet is sent as the equipment of transmission to receiving device.Transmission equipment sends test report according to the set rate Wen Shi, if the set rate is within the bearing capacity of the one-way channel, when transmitting test packet under the set rate, Packet loss or number of dropped packets will not occur in the error range for allowing, i.e., packet loss belongs to normal range (NR)；If the set rate surpasses Gone out the bearing capacity of the one-way channel, then, when test packet is transmitted under the set rate, can produce serious packet loss phenomenon, I.e. packet loss can exceed normal range (NR).

It follows that when the packet loss for calculating belongs to normal range (NR), then illustrate to be tested in this bandwidth test Bandwidth is within the actual bandwidth of the one-way channel；When the packet loss for calculating exceedes normal range (NR), then this sub-band is described The bandwidth that is tested in wide test is beyond the actual bandwidth of the one-way channel.

In embodiments of the present invention, whether normal range (NR) can be belonged to packet loss and is judged by arranging threshold value.Threshold Value can be default fixed numbers, and threshold value can also be changed, adjust accordingly according to specific demand.For example, to special The bandwidth of one one-way channel of line is tested, and the threshold value of setting is 0.05, when the packet loss for calculating is 0.10, packet loss Threshold value, i.e. packet loss are exceeded and have exceeded normal range (NR), then illustrated that the bandwidth that is tested in this bandwidth test cannot represent the list Actual bandwidth to channel.

When above-mentioned packet loss exceedes normal range (NR), illustrate that the bandwidth that is tested in this bandwidth test cannot table Show the actual bandwidth of the one-way channel of special line, in order to the higher limit of the actual bandwidth of the one-way channel is determined, the equipment of transmission can To pass through adjust automatically set rate, bandwidth test is re-started.Specifically, obtain from the receiving device in the transmission equipment After taking the packet loss of the bandwidth test, also include：

Packet loss is higher, illustrates that the actual bandwidth of the one-way channel of the bandwidth and special line that is tested in this bandwidth test is inclined Higher from degree, and set rate is directly proportional to the bandwidth that is tested, it follows that packet loss is higher, illustrates that this bandwidth is surveyed Set rate actual transfer rate corresponding with the actual bandwidth of the one-way channel of the special line deviation of the transmission test packet in examination Degree is higher, then, when the adjustment of set rate is carried out, packet loss is higher, and the adjustment amplitude of corresponding set rate is also bigger.

The embodiment of the present invention is not limited to the concrete adjustment mode for adjusting set rate according to the size of packet loss, permissible It is that the packet loss of bandwidth test and the data of set rate in historical operation are dependent on, counts between packet loss and set rate Corresponding relation, when needing to re-start bandwidth test, then the corresponding relation can be searched according to the packet loss for calculating, Adjust the set rate.For example, threshold value is set to 0.02, when packet loss is 0.05, searches packet loss corresponding with set rate Relation, then set rate can be adjusted to the 80% of former set rate, when packet loss is 0.10, searches packet loss and make a reservation for The corresponding relation of speed, then set rate can be adjusted to the 70% of former set rate.

In the above-described embodiments, the second count value, namely the test to receiving are counted to get for S204 receiving device The number of message is counted, and in this process, not only may only test report in the message received by receiving device Text, it is also possible to receive other types of message, but the sum of receiving device only statistical test message, can't count other The number of the message of type, namely receiving device need have identify which is the energy of test packet from the message for receiving Power, and which is counted.

In order that receiving device can identify which message is test packet, can before bandwidth test is carried out, Transmission equipment and receiving device clearly and set the type of test packet in advance.The embodiment of the present invention also provides a kind of mode Identification of the receiving device to test packet is realized, can be when bandwidth test is carried out, send to receiving device in the equipment of transmission Before test packet, the notice message of the type that include test packet is first sent to receiving device, and receiving device can be according to connecing The notice message for receiving is configured, so as to, in the message for receiving, receiving device can be according to the identification of the information of configuration Go out test packet.Specifically, before the equipment of transmission sends test packet to receiving device, can increase and send to receiving device The correlation step of notice message, as shown in figure 3, the step of increasing includes：

S301：The transmission equipment sends notice message to the receiving device, and the notice message includes the test The type of message.

S302：The receiving device obtains the notice message that the transmission equipment sends.

Illustrate, the type of test packet described here can include the species of message, for example, UDP message, TCP Message etc., feature or feature that the type of test packet can also have including message, the such as destination address of message, source address Etc., can specifically include specific source MAC and target MAC (Media Access Control) address, or specific source IP address and purpose IP address, or The source port number of person's TCP/UDP message and destination slogan, or particular mac address, the end of IP address and TCP/UDP message Combination of slogan etc..When the message with this feature or feature can both be identified the test packet.

The notice message for carrying the type of test packet is sent to receiving device by transmission equipment, and receiving device can be according to According in the type of the test packet, configured, during in order to subsequently received message, can be identified from the message for receiving Test packet.

S303：The receiving device is configured according to the type of the test packet, to realize recognizing the test report Text the function of counting.

When receiving device is configured according to the type of test packet, can be configure corresponding with the type of test packet Message characteristic, in subsequent operation, after receiving device receives message, just can according to configuration message characteristic to receive To message be identified, if the message characteristic of the message for receiving with configuration message characteristic differ, the message is described It is not test packet, then receiving device is not counted；If the message characteristic of the message for receiving and the message characteristic phase for configuring With, then illustrating that the message is test packet, then receiving device is counted, and records the number of test packet.

When receiving device is configured according to the type of test packet, it is also possible to by arranging access control list (Access Control List, ACL), to realize the identification to test packet.

S304：The receiving device is returned to the transmission equipment and confirms message, and the confirmation message is described for identifying Receiving device has completed the configuration for the test packet.

S305：The transmission equipment receives the confirmation message that the receiving device is returned.

Confirm that message can be used for identifying receiving device and configuration for test packet has been completed, having carried out carries out bandwidth The preparation of test.After the configuration that receiving device completes to test packet, can send to the equipment of transmission and confirm message.

Embodiment two

Next, the method that the bandwidth test provided by the embodiment of the present invention is discussed in detail.Fig. 4 is carried for the embodiment of the present invention For a kind of bandwidth test method flow chart, two equipment being applied on special line, described two equipment include that transmission sets Standby and receiving device, the method include：

S401：The transmission equipment sends test information, the test information by the special line to the receiving device Start time and finish time including bandwidth test.

S402：The receiving device obtains the test information that the transmission equipment sends.

S403：The transmission equipment was sent to the receiving device according to set rate and surveys from the start time Examination message is till the finish time.

S404：The receiving device carried out counting to get the second count value, second count value from the start time For the test packet sum that the receiving device is received from the start time to the finish time from the transmission equipment.

It should be noted that S403 and S404 have no the restriction on sequencing, two steps can be carried out simultaneously, from opening Moment beginning starts transmission equipment and sends test packet to receiving device, and receiving device starts to count the test packet for receiving.

S405：The transmission equipment obtains the first count value, and first count value is opened from described for the transmission equipment The test packet sum that moment to finish time beginning is sent to the receiving device.

The acquisition modes of the first count value can have multiple, can by send device statistics draw the first count value, for example, Send device statistics to be carved in the time period of finish time from the outset, the number of the test packet sent to receiving device, system The number that counts out is the first count value.First count value can also be calculated by transmission equipment, and generally, transmission sets For when under set rate to receiving device transmission test packet, the number of the test packet of transmission equipment transmission per second can be Changeless, the time for being carved into finish time experience from the outset is dependent on, transmission equipment can be calculated from the beginning of time The sum of the test packet sent to receiving device to finish time, for example, sends that equipment is per second can send to receiving device Test packet number be 10, that is, send equipment send test packet number speed be 10/second, be carved into knot from the outset The time of bundle moment experience is 100 seconds, then send the test report that equipment is carved into finish time from the outset and sends to receiving device Sum, i.e. first count value of text is 10*100=1000.The embodiment of the present invention is not done to the determination mode of the first count value Limit.

S406：The receiving device returns second count value to the transmission equipment.

S407：The transmission equipment obtains the second count value that the receiving device is returned.

In embodiments of the present invention, can be dependent on the first count value and the second count value carries out the calculating of packet loss, by It is to be drawn by different device statisticses respectively in the first count value and the second count value, when the calculating for needing to carry out packet loss, Need the two count values to be got by same equipment, then lost according to the first count value and the calculating of the second count value by the equipment Bag rate.In the present embodiment, the second count value can be returned to transmission equipment by receiving device, carry out packet loss by transmission equipment Calculating.

Receiving device returns the echo plex mode of the second count value to the equipment of transmission, and the embodiment of the present invention is not limited, permissible Be finish time reach after, receiving device directly by the second count value for counting to get return to transmission equipment, or The message for the second count value of acquisition request sent to receiving device from the equipment of transmission, receiving device are receiving the message Afterwards second count value is returned to transmission equipment.

As receiving device is only will to count to get the second count value transmission equipment is returned to, can't take from reception and set The bandwidth of the standby one-way channel to this direction of transmission equipment, that is to say, that for dissymmetric network, the transmission process will not be received The impact from receiving device to the speed of the one-way channel for sending this direction of equipment is arrived, therefore effectively can be applied to asymmetric The bandwidth test of special line in network.

S408：The transmission equipment calculates losing for the bandwidth test according to first count value and the second count value Bag rate.

Transmission equipment is the originating end of bandwidth test, and transmission equipment can be dependent on the concrete numerical value of packet loss and judge this Whether the bandwidth that is tested in bandwidth test can represent the actual bandwidth of special line one-way channel.Packet loss can be used to indicate that The shared ratio in the transmission total amount of test packet of the quantity of the test packet that loses in bandwidth test.Packet loss can be clear and definite Represent the bearing capacity of channel, when packet loss is too high, represent the carrying for the set rate of test packet being sent beyond channel Ability, when packet loss is relatively low, represents the set rate for sending test packet among the bearing capacity of channel.In the present invention In embodiment, the transmission total amount of test packet can be the quantity of the test packet that transmission equipment is sent to receiving device, i.e., One count value.The quantity of the test packet that the quantity of the test packet of loss can be sent by transmission equipment deducts receiving device and connects The quantity of the test packet for receiving, i.e. the first count value and the difference of the second count value.Packet loss can be by decimal or percentage Several forms represent that a kind of specific computational methods can be the difference for first calculating the first count value and the second count value, should Difference is counted divided by first and is worth to a numerical value, and the numerical value is packet loss, and the numerical value is multiplied by 100% can be converted to The form of percentage.For example, when bandwidth test is carried out, in stipulated time section, the survey that the equipment of transmission is sent to receiving device The sum of examination message is 1000, and it is 980 that receiving device receives the sum of the test packet of transmission equipment transmission, then packet loss Rate can be (1000-980)/1000=0.02, and packet loss can also be represented with percents, i.e. 0.02*100%=2%.

When an one-way channel to special line carries out bandwidth test, packet loss is sent to receiving device with the equipment of transmission and surveys Set rate during examination message is relevant, and in S403, the bandwidth calculation that is tested according to needed for bandwidth test obtains corresponding speed Rate, sends the set rate of test packet as the equipment of transmission to receiving device.Transmission equipment sends according to the set rate and surveys During examination message, if the set rate is within the bearing capacity of the one-way channel, transmission test report under the set rate Wen Shi, will not occur packet loss or number of dropped packets in the error range for allowing, i.e., packet loss belongs to normal range (NR)；If the pre- constant speed Rate can produce serious packet loss beyond the bearing capacity of the one-way channel when then transmitting test packet under the set rate Phenomenon, i.e. packet loss can exceed normal range (NR).

Packet loss is higher, illustrates that the actual bandwidth of the bandwidth and special line one-way channel that is tested in this bandwidth test deviates Degree is higher, and set rate is directly proportional to the bandwidth that is tested, it follows that packet loss is higher, this bandwidth test is described In transmission test packet set rate actual transfer rate corresponding with the actual bandwidth of the one-way channel of special line deviation journey Degree is higher, then when the adjustment of set rate is carried out, packet loss is higher, and the adjustment amplitude of corresponding set rate is also bigger.

By technique scheme as can be seen that before bandwidth test, the transmission in two equipment on special line sets The standby test information for carrying bandwidth test start time and finish time to receiving device transmission so that receiving device can be bright Test packet when is begun for really to be counted, when terminate to count.After the transmission for completing test packet, receiving device is also The test packet sum for being received can be issued transmission equipment so that send equipment and test report can be sent in conjunction with statistics Literary sum calculates packet loss, and transmission equipment can complete bandwidth test according to the concrete numerical value of packet loss.It can be seen that this bandwidth Test mode is independent of the channel width from receiving device to the equipment of transmission, can be effectively for unidirectional letter in dissymmetric network Road carries out bandwidth test.

In the above-described embodiments, the second count value, namely the test to receiving are counted to get for S404 receiving device The number of message is counted, and in this process, not only may only test report in the message received by receiving device Text, it is also possible to receive other types of message, but the sum of receiving device only statistical test message, can't count other The number of the message of type, namely receiving device need have identify which is test packet from the message for receiving, and The ability counted by which.

In order that receiving device can identify which message is test packet, can before bandwidth test is carried out, Transmission equipment and receiving device clearly and set the type of test packet in advance.The embodiment of the present invention also provides a kind of mode Identification of the receiving device to test packet is realized, can be when bandwidth test is carried out, send to receiving device in the equipment of transmission Before test packet, the notice message of the type that include test packet is first sent to receiving device, and receiving device can be according to connecing The advertised information for receiving is configured, so as to, in the message for receiving, receiving device can be according to the identification of the information of configuration Go out test packet.Specifically, before the equipment of transmission sends test packet to receiving device, can increase and send to receiving device The correlation step of notice message, as described in Figure 5, includes the step of increase：

S501：The transmission equipment sends notice message to the receiving device, and the notice message includes the test The type of message.

S502：The receiving device obtains the notice message that the transmission equipment sends.

S503：The receiving device is configured according to the type of the test packet, to realize recognizing the test report Text the function of counting.

When receiving device is configured according to the type of test packet, can be configure corresponding with the type of test packet Message characteristic, in subsequent operation, when receiving device receive transmission equipment transmission message after, just can according to configuration Message characteristic is identified to the message for receiving, if the message characteristic not phase of the message characteristic of the message for receiving and configuration With, then illustrating that the message is not test packet, then receiving device is not counted；If the message characteristic of the message for receiving with join The message characteristic that puts is identical, then illustrate that the message is test packet, then receiving device is counted, and records the individual of test packet Number.

S504：The receiving device is returned to the transmission equipment and confirms message, and the confirmation message is described for identifying Receiving device has completed the configuration for the test packet.
