Description
Technical Field
The present invention relates to the field of network communication technologies, and in particular, to a network performance monitoring method, device, and storage medium.
Background
In-band Network Telemetry (INT) is a process that monitors the Network status by collecting and reporting the status of the Network at the data plane, and this process does not require the participation of the control plane.
The operation and maintenance visualization process based on INT is as follows:
1. the service message enters a source INT transmission device (INTSource) on a transmission path, the service flow message is sampled in a sampling mode arranged on the transmission device, the INTSource encapsulates an INTheader in the message, defines an INTInstruction (instruction), adds INTMetadata (metadata) behind the INTheader, and fills information required to be collected by the transmission device into the INTMetadata.
2. And forwarding the message to a next Hop transmission device (INTTransit Hop) on the transmission path, wherein the INTTransit Hop continuously adds the INTMetadata information of the local device according to the INTMetadata content of the previous device.
3. And the message is forwarded to a target INT transmission device (INTsink) on a transmission path through all INTTransit Hops, the INTsink removes the INTHeader, and sends the path information to a monitoring server at the back end for analysis and presentation through a gPRC (remote procedure call) message.
As shown in fig. 1, it is a schematic diagram of traffic packet transmission between INTSource and INTSink, where MD represents a metadata information stack, and F1, F2, and Fn represent INT metadata stacks on a first Hop (Hop1), a second Hop (Hop2), and an nth Hop (Hop) forward (i.e., direction from INTSource to INTSink) transmission link on a traffic packet transmission path, respectively. The system comprises a PKT HDR, an INTMD SRC, an INTMD Fn and an INTTransit Hop, wherein the PKT HDR refers to a service message packet header, the PKT BODY refers to a service message packet BODY, the INTMD HDR refers to an INT data packet header, the INTMD SRC refers to a collected INTSource metadata stack, and the INTMD Fn refers to an INT metadata stack added by an nth INTTransit Hop on a transmission path.
As can be seen from fig. 1, as the number of transmission devices on the transmission path increases, each transmission device adds an INT metadata stack for representing the device state of the transmission device on the basis of the INT metadata stack of the previous transmission device, which results in a significant increase in the length of the entire service packet, which not only increases the transmission time of the service packet, but also consumes more link bandwidth, and also brings a new challenge to the network switching system, because the length of the data packet header plus the length of the INT metadata may exceed the length of the maximum data packet header that can be processed by the switch.

The INT is to collect Metadata data on each transmission device on the service packet transmission path, and accurately monitor the network state by analyzing the Metadata data.
As shown in fig. 2, it is a schematic diagram of the format of the INTMetadata message, where the INTMetadata message includes a message header of 8 bytes and a plurality of Metadata data, and each Metadata data is data information collected by each hop of device. The INTMetadata header contains the following key fields:
ver (2 bit): a version number;
flags (9 bit): the method comprises the steps of copying allowance, setting exceeding the maximum hop count and the like, and reserving 5-bit Reserved resources;
an Instruction Count (5bit) which is the number of data item instructions collected in Metadata;

The inventor finds that, in the process of transmitting a service message, each transmission device with an INT function on a transmission path needs to check an INT data header, and then inserts the data transmission performance parameters of the current transmission device into the top of an INT metadata stack until the service message reaches a target INT transmission device.
In view of the above, embodiments of the present invention provide a method, an apparatus, and a storage medium for monitoring network performance, according to an embodiment of the present invention, no matter how many hops between a source INT device and a destination INT device, a length of a metadata stack cannot exceed a fixed length, and in real time, the length of the metadata stack may be set according to needs, for example, may be set to 64 bytes. In the embodiment of the present invention, two metadata stacks may be included, where one metadata stack includes a sum of data transmission performance parameters, such as a sum of a hop delay, a queue length, a congestion state, a link utilization rate, and the like, of each transmission device on a service packet forwarding path from the source INT device to the destination INT device. The other metadata stack contains data transmission performance parameters of the worst performance one hop (i.e., bottleneck device) between the source INT device and the destination INT device. As shown in fig. 3a, which is a schematic diagram of a message structure of a service message transmitted by an INT device in the embodiment of the present invention, and as shown in fig. 3b, which is a schematic diagram of a message structure of a service message transmitted by an INT device in the prior art, it can be known from fig. 3a and fig. 3b that an INT message provided in the embodiment of the present invention only includes two data stacks, whereas an INT message provided in the prior art includes n +1 data stacks according to the number n of hop transmission devices in the INT, and each data stack has a length of 32 bytes.
Based on this, an embodiment of the present invention provides a network performance measurement method, as shown in fig. 4, which is a schematic implementation flow diagram of the network performance measurement method provided in the embodiment of the present invention, and includes the following steps:
and S41, receiving the service message.
The service message comprises an INT (in-band network telemetry) data packet header, a first data stack and a second data stack, wherein the first data stack comprises the sum of data transmission performance parameters of each transmission device on a service message transmission path, and the second data stack comprises the data transmission performance parameters of bottleneck devices on the service message transmission path.
The bottleneck device is determined according to the data transmission performance parameter, namely, the transmission device with the worst data transmission performance. In specific implementation, if the data transmission performance parameter includes one, the data transmission performance parameter can be directly determined according to the data transmission performance parameter; if the data transmission performance parameters include a plurality of data transmission performance parameters, in one embodiment, the priority of each data transmission performance parameter may be preset, and the data transmission performance parameter with the highest priority may be compared according to the set priority.
S42, adding the number of the data transmission performance parameters of the current transmission device to the sum of the data transmission performance parameters in the first data stack.
And the transmission equipment currently receiving the service message adds the data transmission performance parameters of the transmission equipment in the first data stack.
And S43, comparing the data transmission performance parameter of the current transmission equipment with the data transmission performance parameter in the second data stack, determining whether to modify the data transmission performance parameter in the second data stack according to the comparison result, and recording the ID of the bottleneck equipment.
In specific implementation, after any transmission node on the transmission path of the service message receives the service message, if the first transmission node on the transmission path has an INT function and is a transmission device, i.e., an INTSource, an INTheader needs to be packaged in the message, an intmeasurement needs to be defined, and a data transmission performance parameter of the current transmission device (i.e., the INTSource) is added in the first data stack and the second data stack.
If the data transmission performance parameter is better than the data transmission performance parameter contained in the second data stack, the data transmission performance parameter contained in the current second data stack is kept unchanged, otherwise, the data transmission performance parameter contained in the second data stack is replaced by the data transmission performance parameter of the current transmission device, and the ID of the bottleneck device is recorded.
When data transmission performance parameters are compared, if one data transmission performance parameter is included, the data transmission performance parameter can be directly determined according to the data transmission performance parameter; if the data transmission performance parameters include a plurality of data transmission performance parameters, in one embodiment, the priority of each data transmission performance parameter may be preset, and the data transmission performance parameter with the highest priority may be compared according to the set priority.
If the last transmission equipment with INT function on the transmission path is the target INT equipment, removing the INT data packet header, the first data stack and the second data stack from the received service message; the sum of the data transmission performance parameters of each transmission device accumulated in the first data stack and the data transmission performance parameters of the transmission bottleneck device in the second data stack are sent to the INT server. And forwarding the service message with the INT data header, the first data stack and the second data stack removed to a final destination of the service message.
Fig. 5 is a schematic diagram of an INT device transmitting a service packet according to an embodiment of the present invention.
In a possible implementation manner, the INT device provided in the embodiment of the present invention may further support backhaul operation (loopback), that is, when a service packet arrives at a designated transmission device supporting an INT function, the device removes a first data stack and a second data stack in the service packet and sends the first data stack and the second data stack to the source INT device in a direction opposite to an original transmission direction of the service packet, and the source INT device may obtain fine-grained traffic congestion information according to the received first data stack and second data stack so as to send feedback of instant traffic control, so as to perform effective congestion control on delay and packet loss sensitive services such as rock (rdma switched ethernet).
In a possible implementation, the source INT device may carry a backhaul transmission device identifier in the service packet, where the backhaul transmission device identifier may be represented by a hop count of the backhaul transmission device in the transmission path, for example, if the INT meta device specifies that the backhaul transmission device identifier is 5, that is, when the service packet reaches the 5 th hop on the transmission path, a backhaul operation is performed; based on this, after receiving the service packet to be forwarded, the backhaul transmission device may execute backhaul operation according to the flow shown in fig. 6:
s61, if the current transmission equipment is determined to be the return equipment according to the return transmission equipment identification, generating a return INT message.
In specific implementation, after any transmission device on the service message transmission path receives a service message to be forwarded, if the current transmission device is determined to be a backhaul device according to the backhaul transmission device identifier carried in the service message transmission path, a backhaul INT message is generated. The INT message carries the following information: the system comprises an exchanged original data packet header (namely, a destination in the original data packet header is changed to a source in the original data packet header, and a source in the original data packet header is changed to a destination in the original data packet header), an INT data packet header, a first data stack and a second data stack, but does not contain a packet body of a service message.
And S62, transmitting the INT message according to the reverse transmission path of the service message.
In specific implementation, the backhaul transmission device sends the backhaul INT message to the source INT device according to the reverse transmission path of the service message.
And then, the back transmission equipment removes the INT data packet header, the first data stack and the second data stack from the received service data packet, and forwards the service message to a final destination, namely, the service message after the INT data packet header, the first data stack and the second data stack are removed is transmitted to the next hop transmission equipment according to the transmission path of the service message.
In specific implementation, the source INT device may detect the performance of the service packet transmission link through backhaul operation, thereby providing finer congestion control for the data forwarding service.
Fig. 7 is a schematic diagram of service packet transmission in a single pass backhaul operation according to an embodiment of the present invention. Wherein, F1, F2 … … Fn represent INT metadata information collected from each transmission device with INT function on the forward transmission link of the service message; the hops 1, 2 … … represent medium-Hop transmission devices on the transmission path.
The above provides a one-way backhaul operation procedure, that is, in the process of reverse transmission, each transmission device only needs to directly forward the backhaul INT message sent by the backhaul transmission device, so that the INT information received by the source INT device is a data transmission performance parameter of the one-way transmission link in the direction from the source INT device to the backhaul transmission device.
In this embodiment, after each transmission device receives the backhaul INT packet, it needs to add a data transmission performance parameter of its own reverse transmission link, that is, a data transmission performance parameter of the reverse transmission link in a direction from the backhaul transmission device to the source INT device, so that the source INT device can obtain complete performance measurement information of the round-trip path.
Fig. 8 is a schematic diagram illustrating service packet transmission in a two-pass backhaul operation according to an embodiment of the present invention. Wherein, F1, F2 … … Fn represent INT metadata information collected from each transmission device with INT function on the forward transmission link of the service message; b1, B2 and … … Bn represent INT metadata information collected from each transmission device with INT function on the service message reverse transmission link; the hops 1, 2 … … represent medium-Hop transmission devices on the transmission path.
Correspondingly, the source INT device may specify a return operation mode in the service message, and in specific implementation, the source INT device may add a return operation identifier in the service message, so that, after the return transmission device receives the service message to be forwarded, if the return transmission device determines that the service message is a one-way return operation according to the return operation identifier, the return INT message is transmitted according to a reverse transmission path of the service message; if the two-pass return operation is determined according to the return operation identifier, increasing the number of data transmission performance parameters of a reverse transmission link of the service message on the sum of the data transmission performance parameters in the first data stack; and comparing the data transmission performance parameters of the reverse data transmission link of the current transmission equipment with the data transmission performance parameters in the second data stack, determining whether to modify the data transmission performance parameters in the second data stack according to the comparison result, and transmitting the back INT message according to the reverse transmission path of the service message.
In specific implementation, in order to support the improved INT function (XINT) provided by the present invention under the current INT framework, the present invention uses the reserved field in the INT message to carry the above information, as shown in fig. 9, which is a schematic diagram of an INT message structure provided by the present invention.
