It should be noted that, in the present disclosure, the embodiments and features of the embodiments may be combined with each other without conflict.

Referring to fig. 1, a flow diagram of one embodiment of a network packet delay detection method according to the present disclosure is shown. As shown in fig. 1, the network message delay detection method includes the following steps:

step 101, in response to detecting that the message transmission time length from the first server to the second server is greater than a preset time length, acquiring time information corresponding to message transmission.

To accommodate the needs of cloud computing, multiple servers are typically provided for the same task. The server here may be a physical server. Information interaction can be carried out among a plurality of servers which finish the same task.

The message is a data unit exchanged and transmitted in the network, and is also a unit transmitted by the network. The message contains complete data information to be sent, and the lengths of the data information may be different. The message is continuously encapsulated into packets, packets and frames for transmission during the transmission process. The encapsulation method can add some headers composed of control information, namely, headers in the messages.

The message may include a plurality of critical transfer nodes in a transfer path between the first server and the second server. Each key transport node may receive a packet forwarded from a last key transport node. Then, a key transmission node may forward the packet to a next key transmission node of the key transmission node in the transmission path that may lead to the destination address according to the destination address information in the packet header. The key transmission node at least comprises the following nodes: the system comprises an application program of a first server, a network protocol stack of the first server, a network card of the first server, a network bridge of the first server, a switch, a network bridge of a second server, a network card of the second server, a network protocol stack of the second server and an application program of the second server.

A transmission sub-path may be formed between two adjacent critical transmission nodes in a transmission path between a first server and a second server. The message transmission path from the first server to the second server may include a plurality of transmission sub-paths.

In some application scenarios, a user may set up a network protocol in a message. Information acquisition instructions may be set in the network protocol. The information may be, for example, time information. If the information is time information, the step 101 may include: and acquiring time information corresponding to message transmission by using a pre-configured network protocol for acquiring time information.

The network protocol can define the port number of a sending port used by a source end and the port number of a destination port when a message is sent from the source end to the destination end; when a message is replied from a destination end to a source end, the port number of a sending port used by the source end, the port number of the destination port and the like; the port numbers can be set according to the requirements of users. And are not limited herein. In addition, a message sequence number field can be set in the network protocol; an extension field. The field of the time information returned by each key transmission node, and the like. The source may be a first server and the destination may be a second server, or the source may be a second server and the destination may be a first server.

In addition, a function (or instruction) for acquiring information corresponding to the key transmission node may be set in the network protocol of the packet. When the message is transmitted to a key transmission node, the information corresponding to the key transmission node can be acquired according to an instruction which is set in the message and used for acquiring the relevant information of the key transmission node.

After each key transmission node receives the message forwarded by the previous key transmission node, the current time information can be read according to the time information acquisition instruction in the message. In some application scenarios, the time information may include a time displayed by an internal clock system of a server where the key transmission node is located when the key transmission node receives the upper packet.

In some optional implementations, the time information corresponding to each key transmission node is collected based on the following steps:

first, a port in a network protocol carried by a message is read.

And secondly, in response to the fact that the port is determined to be a preset port, matching the information of the key transmission node with a preset field of the network protocol, if the matching is successful, calling a preset time acquisition instruction to acquire the value of a timestamp counter corresponding to the key transmission node, and taking the acquired value of the timestamp counter as the time information corresponding to the key transmission node.

The port number may be preset in the network protocol carried in the message. The port number is used to identify different application processes located in the same server. The ports may include a source port and a destination port. Source port: the source port and the IP address serve to identify the return address of the message. Destination port: the destination port indicates an application program interface on the receiving server.

For example, the source end sends a packet to the destination end, and the source end uses the port 4 as a sending port and the port 6 as a destination port. Replying a message from a destination end to a source end, wherein the source end uses a port 6 as a sending port; port 4 serves as the destination port.

For each key transport node, for a packet transmitted to the key transport node, it may be first determined whether a port number set in a network protocol is a preset port number. If the number is the preset port number, the information of the key transmission node can be matched with the preset field of the network protocol. The information of the key transmission node may be, for example, an identifier of the key transmission node. The identification here serves to distinguish between different critical transmission nodes. The identity of the key transport node may for example comprise numbers and/or characters etc. And if the matching is successful, calling a time preset time acquisition instruction to acquire the time indicated by the clock system corresponding to the key transmission node.

In some optional implementation manners, the invoking a preset time acquisition instruction to acquire a value of a timestamp counter corresponding to the key transmission node includes: calling a time acquisition instruction included in a preset code segment in a system kernel corresponding to the key transmission node to acquire the value of a timestamp counter; or dynamically injecting a preset code segment including a time acquisition instruction into a system kernel corresponding to the key transmission node to dynamically acquire the value of the timestamp counter.

In these alternative implementations, a preset code segment, which may include a time acquisition instruction, is embedded in the system kernel corresponding to the key node. The key transmission node can read the port in the network protocol carried by the message transmitted to the key transmission node by executing the preset code segment. And if the port carried by the message is determined to be a preset port, acquiring the value of the timestamp counter by using the time acquisition instruction embedded in the preset code segment in the system kernel associated with the key transmission node.

In addition, before the message is used for detecting the network between the first server and the second server, a Kprobe technology, a bpf technology and the like can be used for injecting a preset code segment including a time acquisition instruction into a system kernel corresponding to each key transmission node, so that the time information can be acquired dynamically. Specifically, when a packet is transmitted to a key transmission node, the key transmission node may run the dynamically injected preset code segment to read a port in a network protocol carried in the packet transmitted to the key transmission node, and determine whether the port is a preset port. If the port carried by the message is determined to be a preset port, the value of the timestamp counter can be acquired by using a time acquisition instruction which is injected into the preset code segment of the key transmission node in advance.

And 102, determining the message transmission duration used for transmitting the message on each transmission sub-path according to the time information.

In this embodiment, the time information is analyzed and processed, so as to obtain the message transmission duration used for transmitting the message in each transmission sub-path.

The message transmission duration may be time information corresponding to a timestamp counter corresponding to a message received by a previous key transmission node on the same message transmission sub-path, and time information corresponding to a timestamp counter corresponding to a message received by a next key transmission node in the message transmission sub-path.

Step 103, determining a target transmission sub-path causing message delay based on the message transmission duration used for transmitting the message in each transmission sub-path.

In this embodiment, since the message transmission duration used by each transmission sub-path to transmit the message is obtained, a target transmission sub-path causing message delay can be determined.

For example, the transmission sub-path that takes the longest time may be determined as the target transmission sub-path.

In some optional embodiments, at least one transmission sub-path with a message transmission duration greater than a preset duration may be determined as the target transmission sub-path.

In the method provided by this embodiment, in response to detecting that the message transmission duration from the first server to the second server is greater than the preset duration, time information corresponding to the message transmission is obtained; the time information comprises the time information of forwarding the message by each key transmission node in a transmission path from the first server to the second server, the transmission path comprises a plurality of key transmission nodes, and each two adjacent key transmission nodes form a transmission sub-path; then, determining the message transmission duration used for transmitting the message in each transmission sub-path according to the time information; and finally, determining a target transmission sub-path causing message delay based on the message transmission duration used by the message in each transmission sub-path. And related key transmission nodes causing message delay are accurately positioned for research and development personnel to analyze, and the network service quality is favorably improved.

With continuing reference to fig. 2, fig. 2 shows a flow of another embodiment of a network packet delay detection method according to the present disclosure, including the following steps:

step 201, in response to detecting that the message transmission duration from the first virtual server to the second virtual server is greater than a preset duration, acquiring time information corresponding to message transmission.

In this embodiment, at least one of the servers is a virtual server.

A virtual server is an emulation of a computer system, the virtual server providing the functionality required to execute the entire operating system based on the computer architecture. On a physical server, virtualization technology (such as KVM/XEN) allows multiple virtual servers to be simulated, and the CPU, RAM, DISK, network, etc. of the physical server are shared among the multiple virtual servers.

In this embodiment, the first server and the second server may be both virtual servers. The first virtual server and the second virtual server may be provided in the same physical server, or may be provided in different physical servers.

In some application scenarios, the first virtual server may be considered as a source virtual server and the second virtual server may be considered as a destination virtual server. The network message is generated from a source end virtual server to a destination end virtual server to be received, and the whole process is as follows: the system comprises an application program of a source end virtual server, a network protocol stack of the source end virtual server, a virtual network card of the source end virtual server, a virtual network bridge of a source end physical server, a network protocol stack of the source end physical server, a network card, a switch of the source end physical server, a network card of a destination end physical server, a network protocol stack of the destination end physical server, a virtual network bridge of the destination end physical server, a network card of the destination end virtual server, a network protocol stack of the destination end virtual server, an application program of the destination end virtual server and the like.

The application program of the source end virtual server, the network protocol stack of the source end virtual server, the virtual network card of the source end virtual server, the virtual network bridge of the source end physical server, the network protocol stack of the source end physical server, the network card of the source end physical server, the switch, the network card of the destination end physical server, the network protocol stack of the destination end physical server, the virtual network bridge of the destination end physical server, the network card of the destination end virtual server, the network protocol stack of the destination end virtual server, and the application program of the destination end virtual server can be regarded as a key transmission node included in a transmission path from the source end server to the destination end server.

Each two adjacent key transmission nodes in the transmission path form a transmission sub-path. For example, a transmission sub-path is formed between an application program of the source end virtual server and a network protocol stack of the source end virtual server; and a transmission sub-path formed between the virtual network card of the source end virtual server and the virtual network bridge of the source end physical server, and the like.

The message may set the network protocol used. The network protocol can define the port number of a sending port used by a source end and the port number of a destination port when a message is sent from the source end to the destination end; when a message is replied from a destination end to a source end, the port number of a sending port used by the source end, the port number of the destination port and the like; the port numbers can be set according to the requirements of users. And are not limited herein. In addition, a message sequence number field can be set in the network protocol; an extension field. The field of the time information returned by each key transmission node, and the like.

In addition, a function (or an instruction) for acquiring information corresponding to a key transmission node may be set in a network protocol of a packet, and when the packet is transmitted to a key transmission node, information corresponding to the key transmission node may be acquired according to the instruction for acquiring related information of the key transmission node, which is set in the packet. The information may be, for example, time information.

After each key transmission node receives the message forwarded by the previous key transmission node, the current time information can be read according to the time information acquisition instruction in the message.

first, a port in a network protocol carried by a message is read.

After reading the port in the network protocol carried by the packet, it may be determined whether the port is a preset port. The preset port may be a port number stated in advance here. For example port number 4, or port number 6.

And secondly, responding to the fact that the determined port is a preset port, matching the information of the key transmission node with a preset field of a network protocol, if the matching is successful, calling a preset time acquisition instruction to acquire the value of a timestamp counter corresponding to the key transmission node, and taking the acquired value of the timestamp counter as the time information corresponding to the key transmission node.

For each key transport node, for a packet transmitted to the key transport node, it may be first determined whether a port number set in a network protocol is a preset port number. If the number is the preset port number, the information of the key transmission node can be matched with the preset field of the network protocol. The information of the key transmission node may be, for example, an identifier of the key transmission node. The identification here serves to distinguish between different critical transmission nodes. The identity of the key transport node may for example comprise numbers and/or characters etc. And if the matching is successful, calling a time preset time acquisition instruction to acquire time information corresponding to the key transmission node.

Further, the invoking of the preset time acquisition instruction to acquire the time information corresponding to the key transmission node includes:

and calling a preset time acquisition instruction to acquire the value of the timestamp counter corresponding to the key transmission node, and taking the acquired value of the timestamp counter as the time information corresponding to the key transmission node.

Since each virtual server runs a complete operating system, there is a clock system internally. A complete operating system runs on the physical server, and the internal clock system and the clock systems of different operating systems are asynchronous.

The timestamp counter (TSC) is a 64-bit register that exists on all x86 processors since pentium. It records the number of clock cycles since reset. The method is a method for acquiring CPU time information by a high-resolution and low-overhead program. The rdtsc instruction may be used to measure the execution time of a certain piece of code. The precision of the execution time of a certain section of code obtained by the method can reach nanosecond level.

Since the virtual machine servers run on the physical server, they use the same timestamp counter, and the difference in timestamps read on the virtual server and on the physical server has a constant offset (TSC offset).

Step 202, determining the message transmission duration used for transmitting the message on each transmission sub-path according to the time information.

In step 201, the value of the timestamp counter corresponding to each key transmission node is obtained, so that the message transmission duration for transmitting the message in each transmission sub-path can be determined.

For example, the timestamp counter corresponding to the message received from the first key transfer node has a value of Q1, and the timestamp counter corresponding to the message forwarded by the second key transfer node has a value of Q2. If the Q1 and the Q2 are both read from the virtual machine server or the physical server, the message transmission time length for transmitting the message on the first transmission sub-path is (Q2-Q1)/K; if Q1 and Q2 are respectively read from the virtual machine server and the physical server, the message transmission time length for transmitting the message on the first transmission sub-path is (Q2-Q1-TSC offset)/K, wherein Q1 and Q2 are integers greater than 1, and K is the CPU clock rate of the physical server corresponding to the first transmission sub-path. Similarly, the message transmission duration for transmitting the message on each transmission sub-path can be obtained. Where TSC offset is the difference between the timestamps read on the virtual server and the physical server with a constant offset.

Step 203, determining a target transmission sub-path causing message delay based on the message transmission duration used for transmitting the message in each transmission sub-path.

In this embodiment, step 203 may be the same as or similar to step 103 in the embodiment shown in fig. 1, and is not described herein again.

As can be seen from fig. 2, compared with the embodiment corresponding to fig. 1, the flow of the network packet delay detection method in this embodiment highlights that the server is a virtual server, and the step of collecting the time information corresponding to the virtual server. Therefore, the scheme described in this embodiment can accurately locate the node where information delay occurs when information is transmitted between the virtual servers, which is beneficial to improving the performance of the virtual servers.

Referring to fig. 3, a schematic structural diagram of an embodiment of a network packet delay detection apparatus according to the present disclosure is shown.

As shown in fig. 3, the network packet delay detection apparatus is applied to packet transmission from a first server to a second server, where a transmission path of the packet transmission includes a plurality of key transmission nodes, and each two adjacent key transmission nodes form a transmission sub-path; the device includes: an acquisition unit 301, a first determination unit 302, and a second determination unit 303.
