" Or " in response to determination ".

It proposes that a kind of network quality detection method, this method can be applied to local terminal server in the embodiment of the present application, joins It as shown in Figure 1, is the flow diagram of the network quality detection method, this method may include:

Step 101, the first connection is established using the first QP resource of local terminal server and opposite end server.

Specifically, local terminal server can use the first QP resource and at least two opposite end servers point of local terminal server The first connection is not established, that is to say, that the same first QP resource can be used in local terminal server and at least two opposite ends service Device establishes the first connection respectively.For example, establish the first connection using QP resource 1 and opposite end server A, using QP resource 1 with it is right End server B establishes the first connection, and so on.

In the above-described embodiments, the first QP resource may include: the QP resource for carrying out network quality detection.Example Such as, the first QP resource that network quality detection can be carried out for the distribution of local terminal server, so that local terminal server can use this First QP resource and at least two opposite end servers establish the first connection respectively.

In the above-described embodiment, first connection can also include but is not limited to: based on UD (Unreliable Datagram, corrupt data transmission) connection, this connection can also be referred to as UD connection.

It wherein, is to utilize this when the first QP resource using local terminal server establishes the first connection with opposite end server 2nd QP resource of the first QP resource and opposite end server of holding server establishes the first connection.Moreover, the 2nd QP resource is The QP resource for being used to carry out network quality detection of opposite end server.

Step 102, the detection messages for carrying the identification information of the first QP resource are sent by the first connection.

In one example, local terminal server can connect to opposite end server by first and send detection messages, the inspection The identification information (such as QP number) of the first QP resource of local terminal server can be carried by observing and predicting text.In addition, the detection messages are also The identification information of the 2nd QP resource of opposite end server can be carried.

In one example, which can include but is not limited to ping detection messages.

In one example, the detection messages for carrying the identification information of the first QP resource are sent by the first connection, it can be with Including but not limited to: local terminal server generates the detection messages for carrying the identification information of the first QP resource, and by the detection messages Store the transmit queue to the first QP resource；Then, local terminal server can read from the transmit queue of the first QP resource and detect Message, and the detection messages are sent by first connection.

In one example, the protocol type that detection messages carry can be UD type, and UD type is for servicing opposite end The processing of device progress corrupt data transmission.That is, after opposite end server receives detection messages, if knowing what detection messages carried Protocol type is UD type, then carries out the processing of corrupt data transmission.

Step 103, the response message for being directed to the detection messages is received by the first connection；Wherein, which is pair End server is sent according to the identification information of the first QP resource to local terminal server.

Wherein, after opposite end server receives detection messages, the first QP resource can be got from the detection messages Identification information, and response message is sent to local terminal server according to the identification information of the first QP resource.

Step 104, message determines the network quality between local terminal server and opposite end server according to response.

Wherein, message determines the network quality between local terminal server and opposite end server according to response, may include but It is not limited to: obtaining the identification information of the first QP resource from the response message, and deposited the response message according to the identification information Store up the receiving queue to the first QP resource；Response message is read from the receiving queue of the first QP resource, and message is true according to response Determine the network quality between local terminal server and opposite end server.

In one example, after establishing the first connection using the first QP resource of local terminal server and opposite end server, Local terminal server can also receive the detection messages that opposite end server is sent by the first connection, wherein can in the detection messages To carry the identification information of the 2nd QP resource of opposite end server；Then, local terminal server can be according to the mark of the 2nd QP resource Know information and sends response message to opposite end server.

Further, the identification information of the first QP resource of local terminal server can also be carried in the detection messages；According to The identification information of 2nd QP resource to opposite end server send response message, can include but is not limited to: local terminal server according to The detection messages are stored the receiving queue to the first QP resource by the identification information of the first QP resource；It is then possible to from the first QP The receiving queue of resource reads the detection messages, and generates the response message for being directed to the detection messages, which can take Identification information with the 2nd QP resource；Then, which is stored to the transmit queue to the first QP resource；It is then possible to The response message is read from the transmit queue of the first QP resource, and connects by first to opposite end server and sends the response report Text.

In one example, local terminal server (can also be used for transmission industry using the 3rd QP resource of local terminal server Be engaged in message QP resource) with opposite end server establish the second connection, by second connect to opposite end server send service message. Wherein, different opposite end servers corresponds to the 3rd QP resource of difference of local terminal server；That is, can use a third QP resource and an opposite end server establish the second connection, and different Q P resource establishes the second connection from different opposite end servers.Example Such as, the second connection is established using QP resource 2 and opposite end server A, establishes the second connection using QP resource 3 and opposite end server B, And so on.

In the above-described embodiment, second connection can also include but is not limited to: based on RC (Reliable Connection, reliable data transmission) connection, this connection can also be referred to as RC connection.

In the above-described embodiment, the protocol type that service message carries can be RC type, and RC type is for making opposite end The processing of server progress reliable data transmission.That is, if knowing, service message is carried after opposite end server receives service message Protocol type be RC type, then carry out the processing of reliable data transmission.

In one example, local terminal server sends the detection for carrying the identification information of the first QP resource by the first connection Message can also include but is not limited to: local terminal server obtains the detection messages for carrying the identification information of the first QP resource；So Afterwards, it determines the priority of detection messages, and is stored the detection messages to priority query according to the priority of detection messages；So Afterwards, it is successively read the message in priority query according to the message sequence in priority query, and is reading the detection messages Afterwards, which is sent by the first connection.

Wherein it is determined that the priority of detection messages, can include but is not limited to: local terminal server determines the first QP resource pair The priority answered；The corresponding priority of first QP resource is determined as to the priority of detection messages.

In the above-described embodiment, for store the priority queries of detection messages with for the preferential of storage service message Grade queue can be same or different.That is, same priority query's storage detection messages and business report can be used Different priority query's storage detection messages and service message also can be used in text.

In one example, above-mentioned execution sequence is intended merely to facilitate description to provide example, in practical applications, Sequence is executed between can also changing the step, with no restrictions to this execution sequence.Moreover, in other embodiments, and it is different The fixed sequence for showing and describing according to this specification is come the step of executing correlation method, step included by method can be than this It is more or less described in specification.In addition, single step described in this specification, it in other embodiments may quilt Multiple steps are decomposed into be described；Multiple steps described in this specification may also be merged into other embodiments Single step is described.

Below in conjunction with concrete application scene, the above-mentioned technical proposal of the embodiment of the present application is described in detail.

Referring to fig. 2 shown in A, it is the application scenarios schematic diagram of the embodiment of the present application, is by taking three servers as an example in Fig. 2A It is illustrated, in practical applications, the quantity of server can also be more, without limitation.

In the present embodiment, server can obtain data from another server using RDMA technology, and RDMA technology is one Data can be transmitted directly to another server from the memory of a server by kind direct memory access technology, without double The intervention of square operating system, does not have any impact to operating system, can be bypassed by hardware realization zero-copy and kernel, nothing The participation for needing CPU is capable of providing high performance data access.

Wherein, the agreement of RDMA technology is supported to can include but is not limited to: IB (InfiniBand, infinite bandwidth), RoCE (RDMA over Converged Ethernet, RDMA cross fusion Ethernet), iWARP (Internet Wide Area RDMA Protocol, internet wide area rdma protocol) etc., it is without limitation.In the present embodiment, it is illustrated by taking RoCE as an example, and The processing mode of other agreements is similar.

RoCE is standard of the RDMA in Ethernet, may include two kinds of transmission modes, and a kind of transmission mode is the transmission side RC Formula, another transmission mode are UD transmission mode.RC transmission mode is connection-oriented reliable transmission technology, needs to pass through response Guarantee the reliability of transmission with mechanism such as order-preservings.UD transmission mode is non-connection-oriented data transmission technology, does not need to provide The mechanism such as response and order-preserving guarantee the reliability of transmission.

If for example, RC transmission mode, after 21 first time of server sends the message for carrying sequence number 1 to server 22, Second of message to the transmission carrying sequence number 2 of server 22 sends the message for carrying sequence number 3 to server 22 for the third time, And so on.After 22 first time of server receives the message for carrying sequence number 1, sequence number 3 is carried if receiving for the second time Message, due to being separated by sequence number 2 between sequence number 3 and sequence number 1, accordingly, it is determined that error of transmission, sends NAK to server 21 (denying) message, request server 21 retransmit the message for carrying sequence number 2, in this manner it is ensured that the reliability of transmission.

Obviously, after 21 first time of server sends the message for carrying sequence number 1 to server 22, second can only be to service Device 22 sends the message for carrying sequence number 2, cannot send the message for carrying sequence number 3.

If UD transmission mode, after 21 first time of server sends the message for carrying sequence number 1 to server 22, second The message for carrying sequence number 2 can be sent to server 22, and the message for carrying sequence number 3 can also be sent to server 22, it is right This is with no restrictions.After 22 first time of server receives the message for carrying sequence number 1, even if receiving carrying sequence number for the second time 3 message, server 22 will not verify sequence number, will not send NAK message, i.e. server 21 not to server 21 Need retransmission mechanism.

In one example, resource is very important resource to QP (Queue Pairs, queue to), is to send and receive The basic resources of message, QP resource include a transmit queue and a receiving queue, and each QP resource has unique mark Information (such as QP number), QP resource is distributed and is managed by network interface card hardware.

For example, with reference to shown in Fig. 2 B, some business between server 21 and server 22 can be known as business 1 (with For a business between server 21 and server 22, in practical application, number of services can be more, and each business is corresponding One QP resource), some business between server 21 and server 23 can be known as business 2, can by server 22 with Some business between server 23 is known as business 3.

For this purpose, needing to distribute QP resource 211 for business 1 in server 21, QP resource 212 is distributed for business 2；It is servicing Device 22, needs to distribute QP resource 221 for business 1, distributes QP resource 222 for business 3；In server 23, need for the distribution of business 2 QP resource 231 distributes QP resource 232 for business 3.

Wherein, QP resource 211 includes transmit queue 2111 and receiving queue 2112, and QP resource 212 includes transmit queue 2121 and receiving queue 2122, QP resource 221 includes transmit queue 2211 and receiving queue 2212, and QP resource 222 includes sending Queue 2221 and receiving queue 2222, QP resource 231 include transmit queue 2311 and receiving queue 2312, and QP resource 232 includes Transmit queue 2321 and receiving queue 2322.

In the above-described embodiments, above-mentioned QP resource 211, QP resource 212, QP resource 221, QP resource 222, QP resource 231, QP resource 232 is to be used for transmission the QP resource of service message.

Based on above-mentioned application scenarios, server 21 can use QP resource 211 and the QP resource 221 of server 22 establishes RC Connection 1；In the establishment process of RC connection 1, the identification information 211 of QP resource 211 is sent to server 22 by server 21, by Server 22 establishes the corresponding relationship of the identification information 221 of QP resource 221 and the identification information 211 of QP resource 211；Similarly, it takes The identification information 221 of QP resource 221 is sent to server 21 by business device 22, is believed by the mark that server 21 establishes QP resource 211 The corresponding relationship of breath 211 and the identification information 221 of QP resource 221.Certainly, the above process is the example for establishing RC connection 1, right The establishment process of this RC connection 1 is with no restrictions.In addition, server 21 can use the QP resource of QP resource 212 Yu server 23 231 establish RC connection 2；Server 22, which can use QP resource 222, to be established RC with the QP resource 232 of server 23 and connect 3；To this It is no longer repeated for process.

In conclusion server 21 is to establish RC connection using different QP resources, QP resource 211 and server are such as utilized 22 establish RC connection 1, establish RC with server 23 using QP resource 212 and connect 2.

Based on above-mentioned RC connection, then the transmission process of service message may include: for business 1, and server 21 is by business Message 1 stores the transmit queue 2111 of QP resource 211.It, can be from QP resource if receiving the service request of server 22 Service message 1 is read in 211 transmit queue 2111, and service message 1 is sent to by server 22, business by RC connection 1 Message 1 can carry the identification information 221 of QP resource 221.After server 22 receives service message 1, since service message 1 is taken Therefore service message 1 can be stored the receiving queue 2212 of QP resource 221 by the identification information 221 with QP resource 221；And And since the record of server 22 has the identification information 221 of QP resource 221 is corresponding with the identification information 211 of QP resource 211 to close System, hence, it can be determined that service message 1 derives from QP resource 211.

In one example, the protocol type that above-mentioned service message 1 carries can be RC type, and RC type is for making to service The processing of the progress reliable data transmission of device 22.Specifically, after server 22 receives service message 1, it can be from service message 1 Parsing protocol type is RC type, and therefore, server 22 carries out the processing of reliable data transmission.For example, server 22 detects Whether the sequence number carried in service message 1 and the sequence number that the service message that last time receives carries are continuous, if continuously, ACK (confirmation) message is sent to server 21, to indicate to have correctly received service message；If discontinuous, to server 21 NAK message is sent, request server 21 retransmits service message 1, to guarantee the reliability of transmission.Certainly, the above process is The example that server 22 carries out reliable data transmission processing is described, it is without limitation.

In above process, identification information 221, the protocol type of QP resource 221 can be carried by having introduced service message 1 For RC type, sequence number, in practical applications, service message 1 can also carry other contents.Moreover, the above process is only logical An example of 1 transmission services message 1 of RC connection is crossed, it is without limitation.

The process for sending service message to server 21 by RC connection 1 for server 22, with above-mentioned service message Transmission process is similar, and details are not described herein.Similarly, server 21 can send service message to server 23 by RC connection 2, Server 23 can send service message to server 21 by RC connection 2, and server 22 can be by RC connection 3 to server 23 send service message, and server 23 can send service message to server 22 by RC connection 3, and service message is transmitted across Journey repeats no more.

In one example, referring to fig. 2 shown in C, one or more priority query can also be configured for service message, In Fig. 2 C for for one priority query of each business configuration.For example, server 21 is 1 configuration preference level queue of business 1, and be 2 configuration preference level queue 2 of business.Based on this, then the transmission process of service message may include: for business 1, service Service message 1 is stored the transmit queue 2111 of QP resource 211 by device 21.If receiving the service request of server 22, from Service message 1 is read in the transmit queue 2111 of QP resource 211, the priority of service message 1 is determined, according to service message 1 The storage of service message 1 is arrived priority query 1 by priority.For example, priority query 1 includes service message 1,2 and of service message Service message 3, based on the priority of each service message, sequence is successively service message 2, service message 1 and service message 3, then Service message 2 is read from priority query 1, and service message 2 is sent to server 22, reads industry from priority query 1 Business message 1, is sent to server 22 for service message 1, and service message 3 is read from priority query 1, service message 3 is sent out Give server 22.

In one example, network quality is the important indicator of RDMA technology, can measure a series of fingers of network behavior Mark, be referred to as QoS (Quality of Service, service quality), network quality may include network connectivty, when Prolong, shake, rate, bandwidth etc..In order to detect network quality, it is complete that RDMA ping (hereinafter referred to as rping) tool can be used At rping tool can establish connection by QP resource, ping message be transmitted using the connection, based on ping message in net The transmission state of network determines network quality.

In conventional manner, it in order to realize the detection of network quality, is illustrated in conjunction with Fig. 2 B, server 21 can configure Two are built for carrying out the QP resource of network quality detection, subsequent title QP resource 213 and QP resource 214, and by QP resource 213 It is vertical to be connect with the RC of server 22, it is established by QP resource 214 and is connect with the RC of server 23.Based on the RC of server 22 company Connect, server 21 can transmit ping message, based on ping message the transmission state of network come determine server 21 and service Network quality between device 22；Based on connecting with the RC of server 23, server 21 can transmit ping message, be reported based on ping Text determines the network quality between server 21 and server 23 in the transmission state of network.

Obviously, in the above method, with the increase of number of servers, need to carry out the QP resource of network quality detection Quantity can also dramatically increase, and therefore, when using aforesaid way, need to waste QP resource, Ke Nengyou using a large amount of QP resource Lead to not the detection for carrying out network quality in QP inadequate resource.

Unlike aforesaid way, in the embodiment of the present application, referring to fig. 2 shown in D, in server 21, can only be Network quality detects business (i.e. rping) and distributes a QP resource 213, rather than distributes at least two QP resources；Similarly, it is taking Business device 22 only can detect one QP resource 223 of traffic assignments for network quality；It can only be network quality in server 23 Detect one QP resource 233 of traffic assignments.

Wherein, QP resource 213 includes transmit queue 2131 and receiving queue 2132, and QP resource 223 includes transmit queue 2231 and receiving queue 2232, QP resource 233 includes transmit queue 2331 and receiving queue 2332.Moreover, in above-described embodiment In, it is for carrying out that above-mentioned QP resource 213, QP resource 223, QP resource 233, which are to be used for transmission the QP resource of detection messages, The QP resource of network quality detection.

Based on above-mentioned application scenarios, server 21 can use QP resource 213 and the QP resource 223 of server 22 establishes UD Connection 1；In the establishment process of UD connection 1, the identification information 213 of QP resource 213 can be sent to server by server 21 22, in this way, server 22 establishes the corresponding relationship of the identification information 223 of QP resource 223 and the identification information 213 of QP resource 213； Similarly, the identification information 223 of QP resource 223 can be sent to server 21 by server 22, in this way, server 21 establishes QP money The corresponding relationship of the identification information 223 of the identification information 213 and QP resource 223 in source 213.Certainly, the above process only establishes UD One example of connection 1, with no restrictions to the establishment process of this UD connection 1.In addition, server 21 continues to use QP resource 213 UD is established with the QP resource 233 of server 23 and connect 2, and server 22 continues to use the QP resource of QP resource 223 Yu server 23 233 establish UD connection 3.

In conclusion UD connection 1, which connects 2 with UD, to be taken using the same QP resource 213 for server 21 Business device 21, which can use the same QP resource 213 and establish UD respectively with server 22 and server 23, to be connect, in this way, this QP money Source 213 is corresponding with the QP resource 223 of server 22, moreover, QP resource 213 is corresponding with the QP resource 233 of server 23.Similarly, Server 22, which can use the same QP resource 223, to be established UD with server 21 and server 23 respectively and connect, and server 23 can It is connect with establishing UD respectively with server 21 and server 22 using the same QP resource 233.

Based on above-mentioned UD connection, then the transmission process of detection messages (such as ping detection messages) may include:

Server 21 generates detection messages 1, and will test the transmit queue 2131 that message 1 stores QP resource 213.So Afterwards, server 21 can read detection messages 1 from the transmit queue 2131 of QP resource 213, and will test report by UD connection 1 Text 1 is sent to server 22.Wherein, which can carry the identification information 213 and QP resource 223 of QP resource 213 Identification information 223.

After server 22 receives detection messages 1, since detection messages 1 carry the identification information 223 of QP resource 223, because This, can will test the receiving queue 2232 that message 1 stores QP resource 223.But due to the QP resource 223 of server 22 The QP resource 213 of corresponding server 21 and the QP resource 233 of server 23, therefore detection report can not be determined based on QP resource 223 Text 1 derives from QP resource 213, is also derived from QP resource 233.For this purpose, detection messages 1 can also carry the mark of QP resource 213 Information 213 is known, so that server 22 determines that detection messages 1 derive from QP resource 213 based on identification information 213.

Due in traditional approach, will not message carry sender QP resource identification information, therefore, the present embodiment In, the format of detection messages can be improved, the mark of the QP resource of sender is added in the extended field of detection messages Information is known, such as the identification information 213 of the QP resource 213 of server 21, in this way, server 22 can be from the extension word of detection messages The identification information 213 of QP resource 213 is read in section.

In one example, the protocol type that above-mentioned detection messages 1 carry can be UD type, and UD type is for making to service The processing of the progress corrupt data transmission of device 22.Specifically, server 22 after receiving detection messages 1, can be reported from detection It is UD type that protocol type is parsed in text 1, and therefore, server 22 carries out the processing of corrupt data transmission.For example, server Whether 22 not need the sequence number carried in analysis detection message 1 continuous, do not need to send to server 21 yet ACK message or NAK message, therefore, server 22 do not need 21 transmission message of request server, are not necessary to guaranty that the reliability of transmission.

Wherein, server 22 from parsed in detection messages 1 protocol type be UD type after, can be from detection messages 1 Extended field in read QP resource 213 identification information 213, it is without limitation.

The above process has introduced the identification information that detection messages 1 carry the identification information 213 of QP resource 213, QP resource 223 223, protocol type is UD type, and in practical application, detection messages 1 can also carry other contents.The above process simply by The example of detection messages 1 is transmitted in UD connection 1, without limitation.

After server 22 will test the receiving queue 2232 that message 1 stores QP resource 223, server 22 can be from QP Detection messages 1 are read in the receiving queue 2232 of resource 223, and generate the response message 1 for being directed to detection messages 1, and will response Message 1 stores the transmit queue 2231 of QP resource 223.Wherein, due to QP resource that server 22 is carried based on detection messages 1 213 identification information 213 determines detection messages 1 from QP resource 213, and therefore, response message 1 carries the mark of QP resource 213 Know information 213.

Further, server 22 is after the transmit queue 2231 that response message 1 is stored to QP resource 223, service Device 22 can read response message 1 from the transmit queue 2231 of QP resource 223, due to carrying QP resource 213 in response message 1 Identification information 213, and the corresponding UD connection 1 of QP resource 213, therefore, server 22 can be by UD connections 1 by response message 1 It is sent to server 21.

After server 21 receives response message 1 by UD connection 1, since response message 1 carries the mark of QP resource 213 Information 213, therefore the identification information 213 of QP resource 213 can be obtained from response message 1, and will ring according to identification information 213 Message 1 is answered to store the receiving queue 2132 of QP resource 213.

Then, server 21 can also read response message 1 from the receiving queue 2132 of QP resource 213, and according to sound Message 1 is answered to determine the network quality between server 21 and server 22, for example, network connectivty, time delay, shake, rate, band Width etc., with no restrictions to the method for determination of this network quality.

In the above process, the network quality between the determining server 21 of server 21 and server 22 has been discussed in detail, For the network quality determination process of other links, similar with the above process, details are not described herein.

In the above-described embodiments, server 21 is after the transmit queue 2131 of QP resource 213 reading detection messages 1, In It will test before message 1 is sent to server 22 by UD connection 1, server 21 can also determine the priority of detection messages 1, And the storage of message 1 will test to priority query according to the priority of detection messages 1；Then, server 21 is according to priority team Message sequence in column is successively read each message in priority query, and after reading detection messages 1, is connected by UD 1 sends detection messages 1.

In one example, for storing the priority query of detection messages and the priority team for being used for storage service message Column can be same or different.That is, same priority query's storage detection messages and service message can be used, Different priority query's storage detection messages and service message can be used.

For example, if being used to store the priority query of detection messages and the priority query's phase for being used for storage service message Together, then it is illustrated by taking Fig. 2 C as an example, server 21 can will test packet storage when sending detection messages to server 22 To priority query 1, server 21 can will test packet storage to priority team when sending detection messages to server 23 Column 2.Based on this, server 21 determines the excellent of detection messages 1 after the transmit queue 2131 of QP resource 213 reading detection messages 1 First grade will test the storage of message 1 to priority query 1 according to the priority of detection messages 1.For example, priority query 1 includes industry Message 1, service message 2 and the detection messages 1 of being engaged in are sequentially successively service message 2, service message 1 based on the priority of each message With detection messages 1, then service message 2 is read from priority query 1, service message 2 is sent to server 22, from priority Service message 1 is read in queue 1, service message 1 is sent to server 22, and detection messages 1 are read from priority query 1, It will test message 1 and be sent to server 22.

In another example if being used to store the priority query of detection messages and being used for the priority query of storage service message not Together, then server 21 may be configured to storage detection messages priority query 3.Therefore, server 21 is from QP resource 213 After transmit queue 2131 reads detection messages 1, determines the priority of detection messages 1, will test according to the priority of detection messages 1 Priority query 3 is arrived in the storage of message 1.If priority query 3 includes detection messages 1 and detection messages 2, based on each detection messages Priority is sequentially detection messages 2 and detection messages 1, then reads detection messages 2 from priority query 3, will test message 2 It is sent to server 22, detection messages 1 are read from priority query 3, message 1 is will test and is sent to server 22.

Wherein, it is stored by will test message and service message to different priority queries, it can be with separate detection message And service message keeps respective independence so that detection messages and service message are not interfere with each other.

In the above-described embodiments, server 21 determines the priority of detection messages 1, can include but is not limited to: server 21 determine the corresponding priority of QP resource 213, and the corresponding priority of QP resource 213 is determined as to the transmission of the QP resource 213 The priority of the detection messages 1 stored in queue 2131.

Wherein, server 21 can be the corresponding priority of QP resource distribution, with no restrictions to this configuration process, and record The corresponding relationship of QP resource and priority is based on this, and the corresponding priority of QP resource can be determined as QP money by server 21 The priority of the detection messages stored in the transmit queue in source.

Based on the above-mentioned technical proposal, in the embodiment of the present application, in network quality detection process, it can use server 21 A QP resource establish UD with multiple opposite end servers and connect, rather than utilize multiple QP resources of server 21 with it is multiple right End server establishes RC connection, to avoid carrying out network quality detection using a large amount of QP resources, QP resource can be saved, big The occupancy to QP resource can be effectively reduced under the scene of scale cluster, improve the availability in large-scale cluster.Moreover, By carrying the identification information of the QP resource of server 21 in detection messages, so that opposite end server can use mark letter It ceases to server 21 and sends response message, is i.e. response message can be sent to correct server 21, avoided by opposite end server The error of transmission of response message.Moreover, server 21 can determine network quality by message according to response, so as to be network fortune Peacekeeping business side provides the ability of quickly investigation network failure；The detection that multiple paths can be carried out with network quality, provides more Comprehensive network quality data, and the influence to service traffics is smaller.

Furthermore, it is possible to the priority query of detection messages flexibly be specified, if specifying the priority for storing detection messages Queue is different from for the priority query of storage service message, then can be with prioritised transmission detection messages, and can reduce detection Influence of the message to service message, improves the accuracy of detection.Moreover, for due to UD transmit caused by unreliable transmission belt come Packet loss, be mapped directly into Network Packet Loss failure；The influence that delay increases is provided by setting baseline and calculating difference Evaluation to network quality variation tendency.
