Embodiment

For the application's above-mentioned purpose, feature and advantage can be become apparent more, below in conjunction with the drawings and specific embodiments, the application is described in further detail.

With reference to Fig. 1, it shows a kind of network condition test flow chart of looking networking described in the embodiment of the present application.

Step 101, the first test lead are connected into looks networking, and by connecting depending on networking and the second test lead.

In the embodiment of the present invention, by testing between the first test lead and the second test lead, adopt depending on the situation of networking transmission data network condition is tested, first depending on networking and second depending between networking by depending on networking connect, particularly, the first test lead is connected into looks networking, and by connecting depending on networking and the second test lead, the second test lead can be connected into and look networking before or after the first test lead is connected into.

In concrete realization, the first test lead and the second test lead can be all Set Top Box, Set Top Box as the first test lead is Set Top Box client (Client end), Set Top Box as the second test lead is server end (server end), and the first test lead and the second test lead also can be connected into the equipment of looking networking for other.

Step 102, described the first test lead generate the test packet that comprises socket information, and according to described socket information through depending on networking to described the second test lead, send described test packet, described socket information identifies described test data and wraps in the transmission path transmitting depending on the data link layer of networking.

After the first test lead and the second test lead connect, to the second test lead, send test packet, by transmission or the reception condition of test packet, network condition is tested.The relevant environment of the Set Top Box of one of application scenarios is Linux environment, will be from the direct transceiving data frame of link layer (MAC) in linux environment, in the embodiment of the present invention, test packet is through looking networking transmission, be with the transmission means difference of traditional Ethernet: when Ethernet transmission data, transfer of data is application layer (network layer) the 3rd layer of ISO, by IP address, the transmitting terminal of data and receiving terminal are identified, during data packet transmission, carried the IP address of transmitting terminal and receiving terminal; When looking networking transmission data, transfer of data is link layer at the second layer of ISO, by link layer information, the transmitting terminal of data and receiving terminal is identified, and carries link layer information during data packet transmission.

In linux environment, can complete respectively and receive and the work of sending out by libpcap and two dynamic base of libnet.Although it is widely used, in requiring to carry out the software of cross-platform transplanting, uses and still have a lot of drawbacks; Because of the video depending on networking, all by two layers (link layers), carry out transceiving data again, simultaneously in order to reduce the usage space of flash.The embodiment of the present invention used a kind of more directly, the mode from link layer transceiving data frame in other storehouse need not be installed, the socket by definition link layer completes.Be packet socket, packet socket for receiving and dispatching initial data frame on MAC layer, and so just permission completes realization at all levels on link layer at user's space, develops or test job bringing great convenience property all.

In the embodiment of the present invention, adopt socket information as the information of link layer.The first test lead adds socket information when generating test packet in test packet, while sending test packet to the second test lead, according to transmitting depending on networking data link layer transmission path of identifying in socket information, socket information can comprise one or more in protocol number, interface index number, header type, packet type, physical layer address and the physical layer address length of the physical layer of data link layer.

Concrete, it is described that according to described socket information, the step through sending described test packet depending on networking to described the second test lead comprises:

Sub-step S11, basis default test bandwidth and default test pack are big or small, determine the number of the test packet of transmission per second;

Sub-step S12, the transmission path identifying according to described socket information, according to the number of the test packet determine sending within default cycle testing time through look networking one by one even bag to the second test lead transmission test packet, wherein, each test packet carries corresponding packet sequence number, and last test packet also carries transmission end mark.

Test packet can comprise a plurality of, can calculate according to the size of default test bandwidth value and test pack the number num_per_sec of the packet of transmission per second, the time cycle of num_per_sec and test, (period) multiplied each other, can obtain total number of test pack, be designated as num=num_per_sec * period, the socket information that then can comprise according to test packet is given out a contract for a project to the second test lead by the action of giving out a contract for a project.Wherein, can according to the size of video packets in unified video, determine the size of test packet, general test packet is fixed as the size of video packets, is all 1084bit.

When sending each test packet, each test packet carries corresponding packet sequence number, and last test packet also carries and sends end mark end, if surpass 2S, does not still receive end, and notice client resends last bag.

All test datas wrap in time cycle of test and send, and can also obtain the theoretical time of each Packet Generation according to the number of default cycle testing time and test packet, can be used as the foundation of follow-up test network condition.

In concrete realization, described default test bandwidth can for add up the actual bandwidth depending on networking that the number of the test packet that repeatedly described in bandwidth test, the second test lead receives obtains, described in depending on the standard bandwidth of networking or described in depending on networking at the maximum available bandwidth not occurring under packet loss situation.Described method can also also comprise, described in adding up by following steps depending on networking at the maximum available bandwidth not occurring under packet loss situation:

Sub-step S21, when the unusual condition of the transmission generation data-bag lost of described test packet, using half of default maximum bandwidth and default minimum bandwidth as described maximum available bandwidth;

Sub-step S22, when there is not the unusual condition of data-bag lost in the transmission of described test packet, by half of described default maximum bandwidth and described default minimum bandwidth or the preset ratio of described default minimum bandwidth, as described maximum available bandwidth.

Default test bandwidth can be also the standard bandwidth of looking networking, for known bandwidth, for example, the special line that has a 10M bandwidth, can do test by 10M bandwidth, but test time packet loss, test next time can be done according to demand the test of another one bandwidth, for example 5M, if also there will be the problems such as packet loss dislocation, can arrange less the testing than 5M.

In the embodiment of the present invention, can carry out repeatedly bandwidth test, obtain in each bandwidth test, the number of the test packet that the second test lead receives is added up the actual bandwidth of looking networking, for example, bandwidth for 20M, once in statistics, adopting 20M as test bandwidth, send 13836 packets, show that packet loss number is 0, sending out a theoretical real time of bag is 433.612610 μ s, explanation test bandwidth is less than or equal to actual bandwidth, actual bandwidth=(size * 8 of the number of the test packet that the second test lead receives * each bag)/(the first test lead is given out a contract for a project institute's time spent)=19.999418Mbps, take 30M as test bandwidth, send 20754 packets, the packet receiving is 14098, illustrate that test tape is wider than actual bandwidth, draw thus, actual bandwidth=(size * 8 of the number of the test packet that the second test lead receives * each bag)/(the first test lead is given out a contract for a project institute's time spent)=20.38Mbps.

The in the situation that of unknown bandwidth, default test bandwidth can be depending on networking at the maximum available bandwidth not occurring under packet loss situation, avoids the own test of doing bandwidth blindly.When default test bandwidth is that while there is not the maximum available bandwidth under packet loss situation depending on networking, the concrete condition that can send according to current data packet is obtained maximum available bandwidth, is similar to binary chop convergence of algorithm algorithm.Particularly, a preset maximum bandwidth and minimum bandwidth, in current test during the unusual condition of test packet generation data-bag lost, can be by half of maximum bandwidth and minimum bandwidth, when there is not the unusual condition of data-bag lost in the transmission of test packet, by half of maximum bandwidth and minimum bandwidth, as maximum available bandwidth, or by the preset ratio of maximum bandwidth and minimum bandwidth, as maximum available bandwidth, in concrete realization, when can be 0 in the value of maximum bandwidth variable, the minimum bandwidth that default test bandwidth equals 3/2, when it is not 0 words, default test bandwidth equals half of minimum bandwidth and minimum bandwidth.

In concrete realization, can obtain default test bandwidth according to concrete environment and application demand.

Step 103, described the first test lead or the second test lead judge whether the transmission of described test packet unusual condition occurs, and the corresponding parameter that characterizes described unusual condition of statistics, so that the described network state depending on networking is diagnosed, described unusual condition comprises data-bag lost, packet dislocation, forward delay interval or sends at least one in shake.

In the embodiment of the present invention, can judge whether the transmission of test packet unusual condition occurs by the first test lead, also can judge whether test packet unusual condition occurs by the first test lead.

Test packet sends to the process of the second test lead from the first test lead, and contingent unusual condition comprises data-bag lost, packet dislocation, forward delay interval or sends the situations such as shake.Abnormal conditions can characterize by corresponding parameter, whether the transmission of determining test packet by judging occurs after unusual condition, can further add up can characterize abnormalities situation various parameters, by these parameters, can further to network condition, diagnose.

In a kind of preferred exemplary of the embodiment of the present invention, in the time of can being judged network condition by the first test lead, when test packet comprises when a plurality of, and when unusual condition comprises data-bag lost and/or packet dislocation, the parameter that characterizes described unusual condition should be bursts dropping ratio and/or packet dislocation rate mutually.

Corresponding described step 103 can comprise:

Sub-step S31, receive the protocol package that expression that described the second test lead returns receives described test packet;

Sub-step S32, extract the receiving and counting parameter in described protocol package, it is poor that described receiving and counting parameter and the test packet number sending within described cycle testing time are done, obtain data-bag lost number, the test packet number of described data-bag lost number and transmission is divided by, obtains described bursts dropping ratio;

And/or, sub-step S33, extract the dislocation statistical parameter in described protocol package, obtain packet dislocation number, the test packet number of described packet dislocation number and transmission is divided by, obtain described packet dislocation rate.

Because line bandwidth takies too highly, the way of packet transmission from one end to other one end, can produce loss.Packet loss is an important indicator of network link, once produce packet loss, the network bandwidth deficiency be described, causes video conference, issues the situations such as Ka Dun or shake, download menu be unsuccessful that there will be such as live.Out of order when occurring, may there is the situation that card pauses in video conference.

In the embodiment of the present invention, the first test lead is after sending test packet, the second test lead corresponding situation to the test packet receiving after receiving test packet is added up, and the parameter of statistics is added in protocol package, and return to the first test lead, the first test lead can determine that the second test lead has received test packet after receiving protocol package (8704 protocol package), and concrete reception condition need to be according to data analysis entrained in protocol package.

Particularly, when statistical data packet loss situation, the parameter of adding up in protocol package can comprise receiving and counting parameter, receiving and counting reference record the number (rcv_num) of the test packet that receives, it is poor that the number (num) of the test packet that receiving and counting parameter and the first test lead are sent is done, further just can obtain the number (loss_pack) of test data packet loss, there is the situation of packet loss in poor non-vanishing explanation, and then further the number of the number of test data packet loss and test packet is divided by, can obtain the Loss Rate of packet, when statistical data packet receives misalignment, the parameter of the statistics in protocol package can comprise dislocation statistical parameter, dislocation statistical parameter has recorded the received test packet of the second test lead the number misplacing has occurred, there is the situation of packet dislocation in the non-vanishing explanation of dislocation statistical parameter, and then further by sniffing bit rate.

In a kind of preferred exemplary of the embodiment of the present invention, in the time of can being judged network condition by the second test lead, when test packet comprises when a plurality of, and when unusual condition comprises data-bag lost and/or packet dislocation, the step whether transmission that accordingly, judges described test packet unusual condition occurs can comprise:

Sub-step S41, described the second test lead, when receiving each test packet, compare the packet sequence number of the current test packet receiving and default reception variable;

If sub-step S42 is inconsistent, determine the situation that data-bag lost and/or packet dislocation occur.

The second test lead receives a plurality of test packets that the first test lead sends, when receiving certain test packet, because test packet carries packet sequence number, therefore, can arrange one and receive variable, receive variable along with the packet receiving increases and changes, the value after variation is identical with the sequence number of the packet that expection should receive under normal circumstances, that is to say that the value of reception variable is the sequence number of the current packet that should receive.The value and the packet sequence number that receive variable are compared, whether normal to determine the current packet receiving, because all may causing the sequence number of the packet that receives, the situation of data-bag lost and packet dislocation is different from the value that receives variable, therefore, when packet sequence number and default reception variable are when inconsistent, may there is at least one situation among data-bag lost and packet dislocation.

For example, receive the packet that the first test lead sends, obtain Bao Xu and end mark position end, Bao Xu is deposited to an array disor_num the inside, obtain maximum bag order max simultaneously; The number rcv_num of the bag receiving in the process receiving is from increasing 1, when current Bao Xuyu receives as occurred bag order is different, be a packet loss number total_loss_pack from increasing 1 action, and a packet loss flag bit is set, shown to occur the situation of packet loss or dislocation.

Further, if when needing the unusual condition of judgement to comprise data-bag lost and packet dislocation simultaneously, after determining the step of the situation that data-bag lost and/or packet dislocation occur, also need further to determine concrete situation, that data-bag lost has occurred actually, or packet dislocation, still either way has.

When the parameter of the described unusual condition of sign is bursts dropping ratio, the corresponding step that characterizes the parameter of described unusual condition of the second test lead statistics comprises:

If there are all packet Bao Xu that receive in theory in the packet Bao Xuzhong that sub-step S51 receives successively, determine the situation that data-bag lost does not occur, if the packet Bao Xuzhong receiving successively does not exist one or more packet Bao Xu that receive in theory, determine the situation that data-bag lost occurs;

Sub-step S52, the packet Bao Xuzhong that receives successively of statistics the number of the non-existent packet Bao Xu receiving in theory, number as described data-bag lost, described data-bag lost number is divided by with determining the test packet number sending, obtains described bursts dropping ratio.

Data-bag lost refer to the number of packet of transmission and the number of the packet that receives inconsistent, packet dislocation refers to that the numeric order of a plurality of packets of transmission is different from the numeric order of a plurality of packets that receive, when the situation of data-bag lost and dislocation is distinguished, the Bao Xu of the packet that the Bao Xuyu of the packet receiving can be received in theory compares, if there are all packet Bao Xu that receive in theory in the Bao Xuzhong of the packet receiving, that is to say that the Bao Xu of the packet receiving and the Bao Xu of theoretic packet are consistent, illustrate that packet all receives, can determine the situation that data-bag lost does not occur, but there is the situation that packet misplaces, otherwise, there is the situation of data-bag lost.

Situation for data-bag lost, the further loss number of statistical data packet, the packet Bao Xuzhong receiving the number of the non-existent packet Bao Xu receiving be in theory the number of data-bag lost, in other words, the number of the number that the number of data-bag lost is the packet Bao Xu that receives in theory and the packet Bao Xu receiving poor, or the number of the number of the packet receiving in theory and the packet that receives is poor, data-bag lost number is divided by with determining the test packet number (that is to say the number of the packet receiving in theory) sending, can obtain Loss Rate.

When the parameter of the described unusual condition of sign is packet dislocation rate, the corresponding step that characterizes the parameter of described unusual condition of the second test lead statistics comprises:

Whether the packet Bao Xuzhong that sub-step S61, judgement receive successively there are all packet Bao Xu that receive in theory, if exist, determines the situation that packet dislocation occurs;

Sub-step S62, the packet bag order that receives is successively formed and receives array, by each packet bag order formational theory array receiving successively in theory;

Sub-step S63, two arrays are compared, number using the number of the different Bao Xu of same position in two arrays as described packet dislocation, described packet dislocation number is divided by with determining the test packet number sending, obtains described packet dislocation rate.

By sub-step S41 and sub-step S42, determine the situation that data-bag lost and/or packet dislocation have occurred, if there are all packet Bao Xu that receive in theory in the packet Bao Xuzhong that further judgement receives, illustrate that packet do not lose, but the situation of packet dislocation has occurred.When the number of concrete definite packet misplacing, the Bao Xu of the packet receiving can be formed to an array (reception array) according to the order receiving, the bag order bag of the data that should receive in theory also forms an array (theoretical array) according to the order that should receive in theory, contrast the difference of these two arrays, if the situation that does not have dislocation and lose, two arrays should be identical, when judgement dislocation, two arrays can be compared, same position in two arrays, when Bao Xu is not identical, this packet dislocation is described, the number of adding up the different Bao Xu of same position in two arrays that is to say the number of dislocation packet, dislocation number is divided by with determining the test packet number (that is to say the number of the packet receiving in theory) sending, can obtain dislocation rate.

As above in example, the theory bag order expected_no (being generally 1) of a current hope is set, the judgement of carrying out the differentiation of packet loss and dislocation is a while circulation (condition is rcv_num and end).Particularly, when certain element of disor_num equates with expected_no, expected_no is put in an array order_num, expected_no is from increasing 1, obtain element that the next one is to be judged the position of array num_dis (be mainly do for optimized algorithm according to), when expected_no is greater than max, jump out while, determine the situation that there is no packet loss but dislocation has occurred.After jumping out while circulation, again disor_num and two arrays of order_num are compared, if disor_num[n] unequal to order_num[n], dis_num++, out of order number is dis_num, and out of order rate is the number that disorderment=(float) ((lose_pack*100)/((float) rcv_num)) % just can obtain the dis_num of dislocation.When certain element of disor_num and the unequal words of expected_no, while goes to 20 elements after num_dis or is greater than the words of total_loss_pack-1, just think that this bag of expected_no lost, err_count is from increasing 1, the Bao Xu that simultaneously records err_count packet loss is expected_no, and which bag demonstrates what specifically lose is.When expected_no is greater than max, jump out while, determine the situation that packet loss has occurred, Loss Rate losepacket_rate=(float) ((lose_pack*100)/((float) send_ptk_num)) %.

In a kind of preferred exemplary of the embodiment of the present invention, in the time of can being judged network condition by the first test lead, when test packet comprises when a plurality of, and unusual condition is while comprising forward delay interval, and corresponding, described step 103 can comprise:

Sub-step S71, for each test packet, when sending each test packet, the transmitting time of record test packet and the Bao Xu of transmission;

Sub-step S72, receive the expression that described the second test lead returns and receive the response packet of described test packet, and judge whether the entrained packet sequence number of described response packet is the current value of described transmission recording parameters;

Sub-step S73, if not, extracts the entrained time of reception of described response packet, does poorly with described transmitting time, obtains forward delay interval time of each test packet.

The transmission range of time delay on the one hand and between transfer of data two places is relevant, and such as Beijing is to Guangdong, theoretical time delay is 50ms left and right at least; Time delay another one reason is the occupancy of the network bandwidth, if occupancy is high, time delay is also high; The other reasons of time delay may be that cpu processes and not catch up with etc., if time delay is excessive, will think that network is slow.The first test lead sends test packet to the second test lead, the second test lead returns to response packet (ACK) after receiving test packet, the first test lead receives response packet and shows that the second test lead has received test packet, if before sending next packet, receive on a response packet that packet returns, explanation sends normal, if after sending next or a plurality of packets, just receive on a response packet that packet returns, the forward delay interval of a packet is described.

When sending each packet, calculated but the number of transmission packet in default cycle testing time, therefore, can further draw the transmitting time of each packet, while sending packet, default transmission recording parameters is done and added 1 processing, after receiving the response packet returning, the Bao Xu that has the packet receiving that response packet carries, if the Bao Xu of response packet is identical with transmission recording parameters current value, there is not transmission lag in explanation, and the Bao Xu of response packet is the Bao Xu of the up-to-date packet sending, if different, there is transmission lag in explanation.

For example, sending recording parameters initial value can be 0, send after first packet, send recording parameters and be increased to 1, if there is not the situation of transmission lag, before sending second packet, can receive response packet, the Bao Xuwei 1 that response packet carries, recording parameters value is identical with sending, if there is the situation of transmission lag, for example, after sending second packet, just receive response packet, the numerical value that response packet carries is 1, owing to sending, send recording parameters after second packet can be increased to 2 be not 1, shown to occur the situation of transmission lag.

After the situation of specified data bag generation forward delay interval, can further calculate the time of forward delay interval, response packet also can carry the time of reception that the second test lead receives packet, the first test lead is also preserved the transmitting time of each packet, and time of reception and the first test lead transmitting time are done difference can obtain forward delay interval time (Round-Trip Time: round-trip delay).

For example, when the first test lead is doing that the action time of giving out a contract for a project obtains that a time send_time(who gives out a contract for a project comprises second and delicate), the second test lead is received the packet sending, when the number rcv_num that receives packet is from increasing after 1, send out a response packet to the first test lead, the statistics being postponed by the first test lead at once.In the response packet that the first test lead is received, Bao Xu is not current theoretical Bao Xu, by the time of reception recv_time in response packet, does difference obtain time delay (RTT) with send_time, is put into ptk_delay_sum array the inside.

Specific algorithm is as follows:

First bag: ptk_delay_sum[0]=t12 – t11

Second bag: ptk_delay_sum[1]=t22 – t21

…

Rcv_num bag: ptk_delay_sum[rcv_num-1]=t rcv_num2 – t rcv_num1

total_time=ptk_delay_sum[0]+ptk_delay_sum[1]+…+ptk_delay_sum[rcv_num]

RTT=(float)total_time/(float)rcv_num

It is the Bao Xu of test pack that the first test lead (client) obtained the time tn1(n that gives out a contract for a project by gettimeofday before this action of giving out a contract for a project away), be put into 1084 bag the insides, issue server end, itself and Bao Xu are put in a structure array S simultaneously.Whether the second test lead (server end) receiving 2012 o'clock, sends out an ACK and wraps the end to client, and ACK size is 72byte, mainly comprises Bao Xu, the end mark of giving out a contract for a project, statistics network time delay etc.

When client receives that server holds the ACK sending, call network delay Processing Interface, the t1 that uses for circulation to find each bag ordered pair to answer from S, then by gettimeofday, obtain a time tn2, do difference, be put into an array ptk_delay_sum the inside, ask max and min value simultaneously, when receiving when giving out a contract for a project end mark, according to ptk_delay_sum array, obtain the total total_time of time delay, do the processing of a mean value, be given to statistics interface, demonstrate RTT value.

In a kind of preferred exemplary of the embodiment of the present invention, when unusual condition comprises transmission shake, on the basis of sub-step S71-S73, described step 103 can also comprise:

Sub-step S74, add up the mean value of the forward delay interval time of each test packet, carry out the poor calculating of smoothed average of transmission continuously according to the forward delay interval time of described mean value and each test packet, as the jitter parameter that sends shake.

If time delay is unstable, neglect fast neglecting slowly, just there is shake in network.Shaking this index, in occasions such as VOIP, video conferences, is a very important index, if produce shake, often sound and image also can be shaken, and cannot catch or see clearly.

According to the method for sub-step S71-S73, can obtain the forward delay interval time of each test packet, at a plurality of test packets, send to prolong to produce and send shake, can first calculate the mean value of the forward delay interval time of each test packet, then done to the poor calculating of smoothed average of continuous transmission the forward delay interval time of mean value and each test packet, the variance obtaining is the jitter parameter that sends shake.

Client end obtained a time tn1 by gettimeofday before this action of giving out a contract for a project away; be put into bag the inside; issue server end; server end receive 2012 time, do the processing of shaking: obtain a time tn2, it is poor that tn1 and tn2 do; obtain tn3; wherein having a last_transit(initial value is 0), if being not equal to 0, delta_t, it equals the absolute value that t3 deducts last_transit; Calculating jitter value jitter(initial value is 0), jitter equals delta_t and deducts jitter, simultaneously t3 assignment to last_transit.Finally jitter is issued to client by 8a07 and hold, computing formula is as follows:

First bag: T13=T11 – T12

Last_transit=T13 (initial value is 0)

Second bag: T23=T21 – T22

delta_t2=T23-last_transit(T13)

Jitter2+=(delta_t2 – 0)/16 (initial value is 0)

last_transit=T23

The 3rd bag: T33=T31 – T32

delta_t3=T33-last_transit(T23)

jitter3+=(delta_t3–jitter2【delta_t2/16】)/16

jitter3+=((T33-T23)–(T23-T13)/16)/16

last_transit=T33

Obtain by that analogy the value of jitter.

Further preferably, the method for the embodiment of the present invention can also comprise:

For example, if test at certain bandwidth packet loss not, represents that network is stable, and network can bear this bandwidth, and if there is no the dislocation of bag, represent that video is very smooth, there is no the situation appearance such as Ka Dun or mosaic; If there is packet loss, network may hold can't stand this bandwidth, if time delay and shake difference are little, represents that network is still more steady, it is so large that the network bandwidth is not tested, and can further add up the problem that " maximum available bandwidth under 0 packet loss " carrys out Sampling network bandwidth.

In concrete realization, can be under set-top box environment, the method of the embodiment of the present invention can be made to corresponding apparatus module moves and carries out test network situation in Set Top Box, for doing depending on the size of its audio frequency and video bag of networking dedicated network Imitating the test of giving out a contract for a project, as shown in Figure 3, provided the system architecture diagram of the network condition test of looking networking of applying the embodiment of the present invention under set-top box environment, Set Top Box A sends and connects to Set Top Box B by looking networking, and reception feedback is determined successful connection, then to Set Top Box B, send packet for test, and according to the protocal analysis packet receiving result of returning, the loss that comprises packet, dislocation, time delay, the situations such as shake, by the analysis to these parameters, diagnose from local terminal the attend a meeting network state of terminal of certain far-end, when video conference or menu etc. goes wrong, other need to know that the technical staff of network condition can be used as the foundation of investigation problem.

In order to make those skilled in the art understand better the present invention, below by a concrete example explanation, describe, wherein, the first test lead is client end, the second test lead is server end.

If a bandwidth depending on networking is 20M, whether truely test bandwidth, can use actual bandwidth to test.
