This application relates to the communication field, and more specifically, to a measurement reporting method and a network node.
With the development of the internet, internet protocol version 6 (Internet Protocol version 6, IPv6) is a next generation IP protocol designed by the Internet Engineering Task Force to replace internet protocol version 4 (Internet Protocol version 4, IPv4). Internet protocol version 6 segment routing (Internet Protocol version 6 Segment Routing, SRv6) is a method designed based on a concept of source routing to forward an IPv6 packet on a network. In segment routing SR based on an IPv6 forwarding plane, a segment routing header (Segment Routing Header, SRH) is inserted into an IPv6 packet, an explicit IPv6 address stack is pushed into the SRH, and transit nodes continuously update destination addresses and offset address stacks, to implement hop-by-hop forwarding. In SRv6, one tunnel may include a plurality of paths to expand network bandwidth, increase a throughput, and improve network flexibility and availability. In an actual network, congestion statuses of paths are different. When congestion statuses of corresponding paths are measured, for a plurality of paths of a same tunnel, measurement results cannot be reported in a timely manner. As a result, measurement reporting precision is low.
This application provides a measurement reporting method and a network node, to improve measurement reporting precision, so that a congestion degree of a corresponding path can be adjusted based on a measurement result of each path.

The following describes the technical solutions of this application with reference to the accompanying drawings.
Therefore, a method for improving measurement packet reporting precision urgently needs to be provided.
The method provided in the embodiments of this application is described in detail below with reference to the accompanying drawings.
In the embodiments shown below, optionally, the first network node and the second network node may be router devices. The first network node may be a sink end (receive end), and the second network node may be a source end (transmit end).
The method is performed in a communication system including the first network node and the second network node, and a plurality of paths are configured for one tunnel between the first network node and the second network node.
The second network node continuously sends a measurement packet to the first network node on each of the plurality of paths at a periodicity of a first time interval. After receiving the measurement packet on each of the plurality of paths, the first network node generates a measurement result of each of the plurality of paths at a periodicity of the first time interval.
The following describes in detail the embodiments of this application by using interaction between the first network node and the second network node as an example.
Step 310: The first network node sets a measurement time interval of each of a plurality of paths as a first time interval.
The first network node may set the measurement time interval of each of the plurality of paths in the following two manners.
Manner 1
The first network node receives a setting packet sent by the second network node, where the setting packet is used to indicate the measurement time interval of each of the plurality of paths, and the setting packet includes the first time interval.
Optionally, that the measurement time interval of each of the plurality of paths is the first time interval may be understood as that measurement time intervals of the plurality of paths are a same time interval. For example, as shown in
The first network node sets the measurement time interval of each of the plurality of paths as the first time interval based on the setting packet. For example, when the first time interval in the setting packet may be 1 ms, the first network node sets the measurement time interval of each of the plurality of paths as 1 ms based on the first time interval in the setting packet. For another example, when the first time interval in the setting packet may be 2 ms, the first network node sets the measurement time interval of each of the plurality of paths as 2 ms based on the first time interval in the setting packet.
Optionally, the setting packet may be further used to indicate a quantity of paths, and the first network node sets the quantity of paths based on the setting packet.
Optionally, the measurement time interval of each of the plurality of paths and the quantity of paths may be indicated by using one setting packet. Alternatively, the measurement time interval of each of the plurality of paths and the quantity of paths may be indicated by using two setting packets. This application sets no limitation on whether the measurement time interval of each of the plurality of paths and the quantity of paths in measurement parameters are indicated by using one setting packet or two setting packets.
Optionally, the first network node sets, based on the setting packet, a quantity of paths measured by the first network node. For example, when the quantity of paths indicated by using the setting packet may be 4, the first network node sets, based on the quantity of paths in the setting packet, the quantity of paths that need to be measured by the first network node as 4. For another example, when the quantity of paths in the setting packet may be 6, the first network node sets, based on the quantity of paths in the setting packet, the quantity of paths that need to be measured by the first network node as 6. This application sets no limitation on the quantity of paths in the setting packet.
For example,
Optionally, the time interval of the result measurement indicated by the measurement interval time field may be understood as that the measurement time interval of each of the plurality of paths is set as the first time interval.
Optionally, the quantity of paths indicated by the tunnel path quantity field may be understood as the quantity of paths that need to be measured by the first network node.
Manner 2
A communication protocol specifies the measurement time interval of each of the plurality of paths and a quantity of paths.
Optionally, the communication protocol specifies that the measurement time interval of each of the plurality of paths is the first time interval. The first time interval may be 3 ms, or the first time interval may be 2 ms.
Optionally, the first network node sets the measurement time interval of each of the plurality of paths as the first time interval according to the specification in the communication protocol. For example, when the first time interval specified in the communication protocol may be 3 ms, the first network node sets the measurement time interval of each of the plurality of paths as 3 ms based on the first time interval specified in the communication protocol. For another example, when the first time interval specified in the communication protocol may be 2 ms, the first network node sets the measurement time interval of each of the plurality of paths as 2 ms based on the first time interval specified in the communication protocol.
Optionally, the communication protocol may further specify the quantity of paths, that is, the communication protocol specifies the quantity of paths that need to be measured by the first network node. The quantity of paths may be 3, or the quantity of paths may be 4.
Optionally, the first network node sets, according to the specification in the communication protocol, the quantity of paths that need to be measured by the first network node. For example, when the quantity, specified in the communication protocol, of paths that need to be measured by the first network node may be 3, the first network node sets, based on the quantity, specified in the communication protocol, of paths that need to be measured by the first network node, the quantity of paths that need to be measured by the first network node as 3. For another example, when the quantity, specified in the communication protocol, of paths that need to be measured by the first network node may be 4, the first network node sets, based on the quantity, specified in the communication protocol, of paths that need to be measured by the first network node, the quantity of paths that need to be measured by the first network node as 4.
After the first network node sets the measurement time interval of each of the plurality of paths and the quantity of paths that need to be measured by the first network node, step 320 may be performed.
Step 320: The second network node receives an acknowledgment packet sent by the first network node, where the acknowledgment packet is used to indicate that the first network node has set the measurement time interval of each of the plurality of paths and the quantity of paths that need to be measured by the first network node.
For example,
When the first network node successfully performs setting based on the acknowledgment packet, and the accept field in the acknowledgment packet indicates 0, step 330 is performed.
Step 330: The second network node sends a first measurement packet, where the first measurement packet is used to indicate the first network node to report measurement results. Correspondingly, the first network node receives the first measurement packet.
Optionally, the first measurement packet is sent by the second network node to the first network node on one of the plurality of paths.
Optionally, in addition to sending the first measurement packet, the second network node may further send a measurement packet of each of the plurality of paths to the first network node at a periodicity of the first time interval. For example, four paths are configured between the first network node and the second network node, that is, a path 1, a path 2, a path 3, and a path 4. The second network node correspondingly sends measurement packets to the first network node on the path 1, the path 2, the path 3, and the path 4 at the first time interval.
Optionally, the first measurement packet is a measurement packet first received by the first network node on the plurality of paths. That is, the first measurement packet may be understood as a measurement packet first received by the first network node in measurement packets sent by the second network node on the plurality of paths. For example, the second network node correspondingly sends the measurement packets to the first network node on the path 1, the path 2, the path 3, and the path 4 at the first time interval. If the first network node first receives a measurement packet sent on the path 1, the first measurement packet is the measurement packet sent on the path 1. If the first network node first receives a measurement packet sent on the path 3, the first measurement packet is the measurement packet sent on the path 3.
Optionally, a moment at which the second network node sends the first measurement packet is different from a moment at which the first network node receives the first measurement packet, and the moment at which the second network node sends the first measurement packet is earlier than the moment at which the first network node receives the first measurement packet. For example, the second network node sends the first measurement packet at a moment of 1 ms, and the first network node receives the first measurement packet at a moment of 2 ms. For example, the second network node sends the first measurement packet at a moment of 1 ms, and the first network node receives the first measurement packet at a moment of 1.8 ms.
For example,
For example, the first network node may receive the first measurement packet at a first moment. If four paths are configured between the second network node and the first network node, when the first measurement packet is a measurement packet sent by the first network node on the path 2, the first moment may be a moment at which the first network node receives the measurement packet sent by the second network node on the path 2. If the moment at which the first network node receives the measurement packet sent by the second network node on the path 2 is 8:10, the first moment is 8:10. For another example, when the first measurement packet is a measurement packet sent by the first network node on the path 4, the first moment may be a moment at which the first network node receives the measurement packet sent by the second network node on the path 4. If the moment at which the first network node receives the measurement packet sent by the second network node on the path 4 is 8:30, the first moment is 8:30.
Step 340: The first network node sends a first result packet to the second network node, where the first result packet includes a result packet corresponding to a measurement result of each of the plurality of paths in the first time interval, and the first result packet is used to indicate the measurement result of each of the plurality of paths in the first time interval. Correspondingly, the second network node receives the first result packet sent by the first network node.
For example, the first network node may send the first result packet to the second network node at a second moment. A time interval between the first moment and the second moment may be the first time interval, that is, the first network node receives the first measurement packet at the first moment, and does not send the result packet at the first moment, but sends the first result packet to the second network node at the first moment plus an end moment of the first time interval. For example, as shown in
Optionally, the first result packet may further include a sequence number of the result packet corresponding to the measurement result of each of the plurality of paths in the first time interval, and the sequence number of the result packet is used to indicate a ranking of the result packet generated by the first network node.
Optionally, the sequence number of the result packet corresponding to the measurement result may be understood as a sequence number of measurement performed by the first network node on a corresponding path to obtain a measurement result of the result packet. Optionally, the first time interval is less than or equal to a first time offset, and the first time offset includes an offset between time at which the first network node generates measurement result packets with a same sequence number.
The same sequence number may be understood as a same transaction number.
The offset between the time at which the first network node generates the measurement result packets with the same sequence number may be understood as an offset between time at which the first network node generates measurement result packets with a same sequence number for different paths. For example, three paths (for example, the path 1, the path 2, and the path 3) are configured between the first network node and the second network node. For the three paths, details are as follows: If the first network node receives the first measurement packet at 1 ms, and the first measurement packet is sent on the path 1, the first network node generates a measurement result packet corresponding to the path 1 for the first time at 1.1 ms. If the first network node receives the 1st measurement packet corresponding to the path 3 at 2 ms, the first network node generates a measurement result packet corresponding to the path 3 for the first time at 2.1 ms. If the first network node receives the 1st measurement packet corresponding to the path 2 at 3 ms, the first network node generates a measurement result packet corresponding to the path 2 for the first time at 3.1 ms. The first time offset may be an offset between time at which the measurement result packet corresponding to the path 1 is generated for the first time, time at which the measurement result packet corresponding to the path 2 is generated for the first time, and time at which the measurement result packet corresponding to the path 3 is generated for the first time. That is, the first time offset may be 2 ms.
For example, if the first time offset is 2 ms, the first time interval needs to be less than or equal to 2 ms. To be specific, if the second network node sends a measurement packet corresponding to one path every 2 ms at most, the first network node generates a measurement result packet corresponding to one path every 2 ms at most. For another example, if the first time offset is 1.5 ms, the first time interval needs to be less than or equal to 1.5 ms. To be specific, if the second network node sends a measurement packet corresponding to one path every 1.5 ms at most, the first network node generates a measurement result packet corresponding to one path every 1.5 ms at most.
Optionally, the first network node sends a second result packet to the second network node at a periodicity of the first time interval, where the second result packet includes a result packet corresponding to a measurement result of each of the plurality of paths in the first time interval, and the second result packet is used to indicate the measurement result of each of the plurality of paths in the first time interval. Correspondingly, the second network node receives, at a periodicity of the first time interval, the second result packet sent by the first network node.
Optionally, the second result packet may further include a sequence number of the result packet corresponding to the measurement result of each of the plurality of paths in the first time interval, and the sequence number of the result packet is used to indicate a ranking of the result packet generated by the first network node.
Optionally, the sequence number of the result packet corresponding to the measurement result may be understood as a sequence number of measurement performed by the first network node on a corresponding path to obtain a measurement result of the result packet.
Optionally, the first network node receives the first measurement packet at the first moment, and does not send the second result packet at the first moment plus an end moment of the first time interval, but periodically sends the second result packet to the second network node at the first moment plus an end moment of N first time intervals, where N is greater than or equal to 2. For example, as shown in
The offset between the time at which the first network node generates the measurement result packets with the same sequence number may be understood as an offset between time at which the first network node generates the measurement result packets with a same sequence number for different paths. For example, three paths (for example, the path 1, the path 2, and the path 3) are configured between the first network node and the second network node. For the three paths, details are as follows: If the first network node receives the first measurement packet at 1 ms, and the first measurement packet is sent on the path 1, the first network node generates the measurement result packet corresponding to the path 1 for the first time at 1.1 ms and generates the measurement result packet corresponding to the path 1 for the second time at 1.2 ms. If the first network node receives the 1st measurement packet corresponding to the path 3 at 2 ms, the first network node generates the measurement result packet corresponding to the path 3 for the first time at 2.1 ms and generates the measurement result packet corresponding to the path 3 for the second time at 2.2 ms. If the first network node receives the 1st measurement packet corresponding to the path 2 at 3 ms, the first network node generates the measurement result packet corresponding to the path 2 for the first time at 3.1 ms and generates the measurement result packet corresponding to the path 2 for the second time at 3.2 ms. The first time offset may be an offset between time at which the measurement result packet corresponding to the path 1 is generated for the first time, time at which the measurement result packet corresponding to the path 2 is generated for the first time, and time at which the measurement result packet corresponding to the path 3 is generated for the first time. The first time offset may alternatively be an offset between time at which the measurement result packet corresponding to the path 1 is generated for the second time, time at which the measurement result packet corresponding to the path 2 is generated for the second time, and time at which the measurement result packet corresponding to the path 3 is generated for the second time. That is, the first time offset may be 2 ms.
For example,
Optionally, the first result packet includes a first-type result packet and a second-type result packet, or the first result packet includes a second-type result packet. A data field in the first-type result packet indicates a first threshold, and the first threshold is used to indicate that the first network node does not generate a measurement result of a corresponding path in the first time interval. A data field in the second-type result packet indicates data of the corresponding path measured by the first network node in the first time interval.
Optionally, the second result packet includes a first-type result packet and a second-type result packet, or the second result packet includes a second-type result packet. A data field in the first-type result packet indicates a first threshold, and the first threshold is used to indicate that the first network node does not generate a measurement result of a corresponding path in the first time interval. A data field in the second-type result packet indicates data of the corresponding path measured by the first network node in the first time interval.
The first-type result packet may be understood as that the first network node does not generate a measurement result of a corresponding path in a corresponding time interval, and the data field in the first-type result packet indicates the first threshold. The second-type result packet may be understood as that the first network node generates a measurement result of a corresponding path in a corresponding time interval, and the data field in the second-type result packet indicates the data of the corresponding path measured by the first network node in the first time interval.
Optionally, the first threshold may be 0.
When the first threshold is 0, if the data field in the result packet indicates 0, the first network node does not generate the measurement result of the corresponding path in the corresponding time interval; if the data field in the result packet indicates other data, the first network node generates the measurement result of the corresponding path in the corresponding time interval. For example, as shown in
Optionally, in the method 300, step 350 may be further performed.
Step 350: The second network node adjusts bandwidth utilization of each path based on the result packet.
The second network node extracts, based on the result packet, the measurement result that is of each of the plurality of paths and that is in the result packets with the same sequence number. When measurement results corresponding to at least two of the plurality of paths include measurement data, the second network node adjusts bandwidth utilization of a corresponding path based on the measurement results corresponding to the at least two of the plurality of paths.
