[0003] Currently, the RFC (Request for Comments) standard also specifies some IOAM methods. For example, in the passport method, each hop in the message forwarding path needs to collect and carry OAM metadata.

[0004] However, the passport method cannot monitor packet loss and packet loss position, nor can it perform periodic performance measurement of packet loss, delay, etc. Moreover, the above-mentioned IOAM method has the problem of low flexibility of traffic message processing. SUMMARY

[0087] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0088] Figure 1 This is a schematic diagram illustrating the implementation environment of a message processing method provided in an embodiment of this application.

[0089] The message forwarding path includes multiple nodes: such as Figure 1 The message encapsulation node and the pass-through node shown are... Figure 1 Two pass-through nodes and a message decapsulation node are illustrated exemplarily. The message encapsulation node and its connected pass-through nodes communicate via a network; interconnected pass-through nodes communicate via a network; the message decapsulation node and its connected pass-through nodes also communicate via a network; and the message encapsulation node, message decapsulation node, and pass-through node each communicate with the receiving entity via a network.

[0090] Of course, in other possible implementations, the message forwarding path may also include only message encapsulation nodes and message decapsulation nodes, which communicate with each other over a network.

[0091] Wherein, the message encapsulation node, the penetration node, the message decapsulation node and the receiving entity can be servers, and the servers can be single servers or a server cluster composed of multiple servers.

[0092] In the passport mode, each hop in the message forwarding path needs to collect and carry OAM metadata in the traffic message, and then deliver the traffic message carrying the OAM metadata to the next node, and the next node continues to collect the OAM metadata and carries the OAM metadata in the received traffic message and then continues to deliver downward. However, this mode has the problem that the node collects IOAM data and carries it in the message to deliver downward, and once a message is lost, the IOAM trace monitoring is interrupted, resulting in low flexibility of traffic message processing. Moreover, the passport mode cannot monitor packet loss and packet loss position, and cannot perform periodic packet loss, delay and other performance measurements.

[0093] Based on the above-mentioned conventional technology, the embodiments of the present application provide a message processing method, which defines an indication field, and indicates the node in the message forwarding path to report IOAM data to the receiving entity through the IOAM trace type field in the indication field. In this way, the node can directly report IOAM data to the receiving entity, avoiding the problem that in the conventional technology, the node collects IOAM data and carries it in the message to deliver downward, and once a message is lost, the IOAM trace monitoring is interrupted, resulting in low flexibility of traffic message processing. The embodiments of the present application improve the flexibility of traffic message processing. In addition, the indication field also includes a packet loss measurement field and a delay measurement field. Based on the packet loss measurement field and the delay measurement field, the node in the message forwarding path can perform packet loss measurement and delay measurement, etc., to integrate network performance measurement into the IOAM method.

[0094] It should be noted that the beneficial effects or technical problems solved by the embodiments of the present application are not limited to this, but also other implicit or related problems. For specific descriptions, please refer to the descriptions of the following embodiments.

[0095] In one of the embodiments, as shown in Figure 2 , a message processing method is provided. Taking the message encapsulation node in the message forwarding path of the method applied to Figure 1 as an example, the method includes the following steps:

[0096] Step 201, the message encapsulation node encapsulates an indication field for the forwarded traffic message.

[0097] Please refer to Figure 1In the transmission process of the service flow, each traffic message in the service flow first reaches a message encapsulation node in the message forwarding path, and then, for each traffic message, the message encapsulation node needs to encapsulate the traffic message. Exemplarily, the message encapsulation node needs to encapsulate a message header for the traffic message.

[0098] For example, in an IPv6 (Internet Protocol Version 6) network environment, the message encapsulation node needs to encapsulate an IPv6 message header for each traffic message; in an IPv4 (Internet Protocol Version 4) network environment, the message encapsulation node needs to encapsulate an IPv4 message header for each traffic message.

[0099] In the embodiment of the present application, when it is needed to simultaneously perform network performance measurement and IOAM trace monitoring on a certain service flow forwarded by the message encapsulation node, the message encapsulation node must correspondingly insert an indication field corresponding to each traffic message in each traffic message in the service flow. That is, in the process of encapsulating each traffic message in the service flow, the message encapsulation node encapsulates the indication field corresponding to each traffic message together with the traffic message. Exemplarily, the message encapsulation node can encapsulate the indication field corresponding to the traffic message in the message header of the traffic message.

[0100] The determination of whether a service flow needs to simultaneously perform network performance measurement and IOAM trace monitoring can be determined by the controller, and then the controller sends the flow identifier of the service flow that needs to simultaneously perform network performance measurement and IOAM trace monitoring to the message encapsulation node, and the message encapsulation node can determine the service flow according to the flow identifier. Of course, the message encapsulation node can also determine whether a service flow needs to simultaneously perform network performance measurement and IOAM trace monitoring by itself, and take the service flow that simultaneously performs network performance measurement and IOAM trace monitoring as the service flow.

[0101] Step 202, the message encapsulation node sends the traffic message encapsulated with the indication field.

[0102] After the message encapsulation node encapsulates the indication field for each traffic message, the message encapsulation node sends the traffic message encapsulated with the indication field to the next node connected with the message encapsulation node in the message forwarding path.

[0103] As described above, the next node connected with the message encapsulation node can be a penetrating node as shown in FIG. 1, of course, in the case that the message forwarding path only includes the message encapsulation node and the message decapsulation node, the next node connected with the message encapsulation node can also be the message decapsulation node, which is not specifically limited herein. Figure 1

[0104] ​The indication field includes an IOAM trace type field, a packet loss measurement field, and a delay measurement field.

[0105] In other possible embodiments, the indication field further includes an extension flag field, a namespace identification field, a flag field, and a reserved field.

[0106] Referring to Figure 3 , Figure 3 is a schematic diagram of an exemplary indication field. As shown in Figure 3 , the IOAM-Trace-Type field is the IOAM trace type field, the L field is the packet loss measurement field, the D field is the delay measurement field, the Extension-Flags field is the extension flag field, the Namespace-ID field is the namespace identification field, the Flags is the flag field, and the Reserved is the reserved field.

[0107] Each field included in the indication field has a corresponding meaning and function. Hereinafter, the meaning and function of each field in the indication field are introduced.

[0108] 1) The IOAM trace type field is used to instruct the node in the packet forwarding path to report IOAM data to the receiving entity according to the indication of the IOAM trace type field.

[0109] First, the node in the packet forwarding path mentioned herein is introduced. In the embodiments of the present application, the meaning of the node in the packet forwarding path is different based on different measurement modes. For example, in the hop-by-hop measurement mode, the node in the packet forwarding path refers to all nodes in the packet forwarding path, such as the packet encapsulation node, the penetration node, and the packet decapsulation node shown in Figure 1 ; in the end-to-end measurement mode, the node in the packet forwarding path refers to the head node (i.e., the packet encapsulation node) and the tail node (i.e., the packet decapsulation node) in the packet forwarding path.

[0110] The determination of the above two measurement modes will be introduced in the embodiments below and will not be described in detail here. The IOAM trace type field is further described herein.

[0111] In the embodiments of the present application, the IOAM data includes one or more of a node ID, an ingress interface ID of the packet in the node, an egress interface ID, and a timestamp, for example.

[0112] Thus, after receiving the traffic packet encapsulated with the indication field sent by the packet encapsulation node, the packet receiving node in the packet forwarding path (i.e., the node in the packet forwarding path except the packet encapsulation node, and it can be understood that the steps performed by the packet receiving node in the embodiments of the present application can also be performed by the packet encapsulation node) reports the IOAM data to the receiving entity according to the indication of the IOAM trace type field in the packet. For example, the packet receiving node reports the node ID, the ingress interface ID and the egress interface ID of the packet in the node.

[0113] As an implementation, the IOAM trace type field includes a plurality of bits. For example, the IOAM trace type field includes 24 bits. Different bits correspond to different IOAM data types, and the values of different bits are used to indicate whether the nodes in the packet forwarding path report the IOAM data to the receiving entity.

[0114] For example, for a traffic packet, the packet encapsulation node sets the second highest bit (the first bit, and the highest bit is the 0th bit) in the IOAM trace type field encapsulated by the packet encapsulation node to "1", indicating that the nodes in the packet forwarding path need to output the IOAM data of the ingress interface ID and the egress interface ID of the node to the receiving entity, and so on.

[0115] In a possible implementation, for IOAM trace monitoring, the traffic packets in the service flow all need to be subjected to IOAM trace monitoring. Thus, for each traffic packet in the service flow, when the packet encapsulation node encapsulates the indication field, it needs to mark the bit corresponding to the IOAM data type in the IOAM trace type field as the first value, for example, "1", and mark the other bits in the IOAM trace type field as the second value "0".

[0116] In another possible implementation, for IOAM trace monitoring, the IOAM encapsulation node only needs to select a subset of the traffic packets to be forwarded, i.e., only part of the traffic packets in the service flow need to be subjected to IOAM trace monitoring. The packet encapsulation node selects part of the traffic packets from the traffic packets in the service flow through a preset packet selection strategy, and then, for each selected traffic packet, when the packet encapsulation node encapsulates the indication field, it needs to mark the bit corresponding to the IOAM data type in the IOAM trace type field as "1" and mark the remaining bits as "0"; and for the unselected traffic packets in the service flow, when the packet encapsulation node encapsulates the indication field for each unselected traffic packet, it needs to mark all 24 bits in the IOAM trace type field as "0", so that the nodes in the packet forwarding path do not need to generate the IOAM data of the traffic packet and output it to the receiving entity.

[0117] In this way, when the receiving node reports the IOAM data to the receiving entity according to the indication of the IOAM trace type field, for each traffic packet, the receiving node can first determine the type of IOAM data that needs to be reported to the receiving entity according to the value of each bit in the IOAM trace type field. If a bit is marked as "1", it means that the IOAM data of the IOAM data type corresponding to the bit needs to be reported for the traffic packet. If a bit is marked as "0", it means that the IOAM data of the IOAM data type corresponding to the bit does not need to be reported for the traffic packet. If all bits in the IOAM trace type field of a traffic packet are marked as "0", it means that no IOAM data of any type needs to be reported for the traffic packet. Then, the receiving node reports the IOAM data of the corresponding IOAM data type to the receiving entity.

[0118] In the prior art, a postcard mode of IOAM is also defined. In the postcard mode, each hop in the traffic forwarding path needs to generate an OAM metadata for each packet and report the OAM metadata to the centralized controller, and the OAM metadata generated by each hop is not attached to the traffic packet.

[0119] However, in this IOAM mode, each hop in the traffic forwarding path needs to generate an independent OAM packet for each packet in the monitored traffic flow. For example, if there are 1000 packets in the monitored traffic flow, each hop needs to generate 1000 OAM packets for the traffic flow and report the OAM packets to the centralized controller, which consumes a large amount of network and centralized controller resources.

[0120] In the embodiments of the present application, as described above, for IOAM trace monitoring, the IOAM encapsulation node only needs to select a subset of the traffic packets, i.e., only part of the traffic packets in the traffic flow need to be monitored for IOAM trace monitoring, so that the number of packets for IOAM trace monitoring can be greatly reduced, the amount of IOAM data can be reduced, and the network resources of the network and the centralized controller can be saved.

[0121] 2) The packet loss measurement field is used to indicate that the nodes in the traffic forwarding path perform packet loss measurement according to the indication of the packet loss measurement field.

[0122] For network performance measurement, the IOAM encapsulation node must mark the packet loss measurement field in the indication field of each packet.

[0123] In the embodiments of the present application, the packet loss measurement field includes one bit. In combination with the value of the bit in the packet loss measurement field of each traffic packet, the nodes in the traffic forwarding path can also determine a measurement period and perform packet loss measurement according to the measurement period.

[0124] Exemplarily, the field values of the packet loss measurement fields of the traffic packets belonging to the same packet batch in the service flow are the same, and the traffic packets belonging to the same packet batch are multiple continuous traffic packets, in addition, the field values of the packet loss measurement fields of the traffic packets belonging to different packet batches in the service flow are different; the packet loss measurement field is specifically used to instruct a node in a packet forwarding path to determine the packet batch to which a packet belongs according to the field value of the packet loss measurement field, and report a packet count value corresponding to the packet batch to a receiving entity.

[0125] Exemplarily, referring to Figure 4 , Figure 4 is a schematic diagram of a node in a packet forwarding path reporting a packet count value. The packet batch can be used as a measurement period, and the node in the packet forwarding path reports a packet count value corresponding to the packet batch in each batch (i.e., each measurement period).

[0126] In combination with Figure 5 , Figure 5 is a schematic diagram of a field value of a packet loss measurement field (such as an L field shown in Figure 3 ) in an indication field of a traffic packet in a service flow. In the process of encapsulating the indication field of each traffic packet by the packet encapsulation node, the traffic packets are grouped according to batches (Batch) to obtain multiple packet batches: Batch1, Batch2, Batch3, etc., each packet batch includes multiple traffic packets, then the field values of the packet loss measurement fields of multiple continuous traffic packets belonging to the same packet batch are marked as the same value, and the field values of the packet loss measurement fields of the traffic packets of different packet batches are alternated between a first value (for example, 1) and a second value (for example, 0).

[0127] The packet encapsulation node can divide the traffic packets into multiple packet batches according to a fixed number of packets or a fixed timer. The fixed number of packets is, for example, every 1000 continuous traffic packets as a packet batch, and the fixed timer is, for example, multiple continuous traffic packets within 10s as a packet batch.

[0128] In this way, in the process of packet loss measurement according to the indication of the packet loss measurement field, for each traffic packet in the service flow, the receiving node determines the packet batch to which the traffic packet belongs according to the field value of the packet loss measurement field, for example, the field value of the first 1000 continuous traffic packets is 1, and the field value of the 1001th traffic packet is 0, so the first 1000 traffic packets are determined as Batch 1; the field value of the 1001th to 2000th continuous traffic packet is 0, and the field value of the 2001th traffic packet is 1, so the 1001th to 2000th traffic packet is determined as Batch 2, and so on. Then, according to the packet batch, the receiving entity reports the packet count value corresponding to the packet batch, that is, for Batch 1, the receiving node reports the number of packets it receives, 1000; for Batch 2, the receiving node reports the number of packets it receives, 1000, and so on.

[0129] The receiving entity can measure the packet loss between any nodes in each period by periodically comparing, that is, for each packet batch, comparing the packet count values reported by different nodes in the packet forwarding path, thereby realizing packet loss measurement of the service flow.

[0130] It should be noted that, compared with the postcard method in the prior art, each hop in the packet forwarding path needs to generate an OAM metadata for each packet and report it to the centralized controller, and the centralized controller analyzes the OAM metadata of each traffic packet to perform packet loss measurement, which has the problem of large data volume in the packet loss measurement process and excessive consumption of network resources.

[0131] However, in the delay measurement process, the node only reports the packet count value of the batch for packet loss measurement, thereby greatly reducing the data volume in the delay measurement process and reducing the consumption of network resources.

[0132] As an implementation manner, the node in the packet forwarding path reports the IOAM data to the receiving entity, which can also be reported according to the above packet batch, that is, for a packet batch, the node in the packet forwarding path reports the packet count value in the packet batch and the IOAM data of all or part of the traffic packets in the packet batch, while supporting network performance measurement and IOAM trace monitoring.

[0133] 3) The delay measurement field is used to indicate that the node in the packet forwarding path performs delay measurement according to the indication of the delay measurement field.

[0134] For network performance measurement, the IOAM encapsulation node needs to mark the delay measurement field in the indication field of a single traffic packet in each packet batch. As an implementation manner, the packet in the middle position of each packet batch can be selected as the single packet.

[0135] As an implementation, the time delay measurement field includes 1 bit. When the message encapsulation node encapsulates the indication field in the traffic message of the message forwarding path, the message encapsulation node determines the target traffic message from each message batch during the encapsulation of the time delay measurement field. As described above, for example, the traffic message in the middle position of each message batch is selected as the target traffic message. Then, the message encapsulation node sets the 1 bit position of the time delay measurement field of the target traffic message to a first value (e.g., 1), and sets the 1 bit position of the time delay measurement field of the other traffic messages in the message batch to a second value (e.g., 0), and the first value and the second value are different.

[0136] Exemplarily, referring to Figure 6 , Figure 6 FIG. 1 is a schematic diagram of a message timestamp reported by a node in a message forwarding path to a target traffic message according to an embodiment of the present application. In the figure, a message batch can be regarded as a measurement period, and the node in the message forwarding path reports the message timestamp of the target traffic message in each batch (i.e., each measurement period).

[0137] In combination with the packet loss measurement process, on the basis of Figure 5 , referring to Figure 7 , Figure 7 FIG. 2 is a schematic diagram of the field value of the packet loss measurement field L and the time delay measurement field D in the indication field of the traffic message according to an embodiment of the present application. During the process of encapsulating the indication field by the message encapsulation node in the nodes in the service flow, the traffic messages are grouped according to batches to obtain multiple message batches: Batch1, Batch2, Batch3, etc., and each message batch includes multiple traffic messages. Then, the field values of the packet loss measurement fields of the multiple continuous traffic messages belonging to the same message batch are marked as the same value, and the field values of the packet loss measurement fields of the traffic messages of different message batches are alternated between 1 and 0. Then, the message encapsulation node determines the target traffic message from each message batch. Then, the message encapsulation node sets the 1 bit position of the time delay measurement field of the target traffic message to 1, and sets the 1 bit position of the time delay measurement field of the other traffic messages in the message batch to 0.

[0138] The time delay measurement field set to the first value is specifically used to instruct the node in the message forwarding path to report the message timestamp of the target traffic message to the receiving entity. The time delay measurement field set to the second value is specifically used to instruct the node in the message forwarding path to prohibit reporting the message timestamp of other messages to the receiving entity.

[0139] In this way, during the process of delay measurement by the message receiving node according to the indication of the delay measurement field, for each message batch, the target traffic message with the delay measurement field set to the first value can be determined from each traffic message in the message batch, and the message timestamp (i.e., the reception timestamp) of the target traffic message is recorded. The message receiving node reports the message timestamp of the target traffic message to the receiving entity, and prohibits reporting the message timestamps of other messages in the message batch with the delay measurement field set to the second value to the receiving entity.

[0140] The receiving entity can measure the latency of traffic packets between any nodes by periodically comparing the timestamps of the same traffic packets reported by different nodes in the packet forwarding path for each packet batch.

[0141] In the traditional postcard method, the centralized collector collects OAM metadata reported by each node and performs correlation analysis on the OAM data reported by all nodes to monitor packet loss and packet loss location. However, this IOAM method cannot periodically monitor key performance indicators such as packet loss, latency, and jitter of the business flow.

[0142] The embodiments of this application define an indication field in the manner described above to support IOAM's periodic measurement function of indicators such as packet loss and latency.

[0143] 4) The extended flag field includes multiple bits and is used to indicate the flow identifier and message sequence identifier in the message forwarding path. For example, the extended flag field includes 8 bits, and when each bit of the extended flag field is set to "1", it indicates that there is a corresponding optional 4-byte field in the indication field.

[0144] For example, when the 0th bit among multiple bits is set to the first value, it indicates that an optional flow identifier field, Flow ID (Optional), exists in the indication field. This optional 4-byte field is used to encapsulate the flow identifier and includes 32 bits. The 0th bit is used to indicate the flow identifier of the service flow in the packet forwarding path.

[0145] For example, see Figure 8 , Figure 8 This is a schematic diagram illustrating an example of a field.

[0146] It can be understood that, in the case that the 0th bit of the extension flag field is set to the first value, the field value of the optional flow identifier field in the indication field is the same for each traffic message in the service flow, i.e., the flow identifiers are all the flow identifier of the service flow. When the 0th bit of the extension flag field is set to the first value when the indication field of each traffic message is parsed, the message receiving node uploads the flow identifier of the service flow when reporting the IOAM data, the message count value and the message timestamp, so that the receiving entity performs IOAM trace monitoring and network performance measurement on the flow identifier.

[0147] In the case that the 1st bit in the plurality of bits is set to the first value, it indicates that there is an optional message sequence identifier field Sequence Number (Optional) in the indication field, i.e., the optional 4-byte field is the sequence identifier field. The optional sequence identifier field is used to encapsulate the message sequence identifier belonging to the same service flow, and the optional sequence identifier field includes 32 bits. Among them, the 1st bit is used to instruct the nodes in the message forwarding path to report the message sequence identifier of the message in the service flow to the receiving entity.

[0148] In addition, in the indication field of the embodiment of the application, the namespace identifier field includes 16 bits, the flag field includes 8 bits, and the reserved field includes 6 bits.

[0149] In one of the embodiments, based on Figure 2 As shown in the embodiment, referring to Figure 9 The embodiment relates to an implementation of an exemplary message encapsulation node encapsulating an indication field for a traffic message in a service flow corresponding to a message forwarding path. As shown in Figure 9 The step 201 includes:

[0150] The step 901: The message encapsulation node encapsulates the indication field in the first message header in the traffic message to instruct the nodes in the message forwarding path to perform hop-by-hop IOAM data reporting; or the message encapsulation node encapsulates the indication field in the second message header in the traffic message to instruct the nodes in the message forwarding path to perform end-to-end IOAM data reporting on the traffic message.

[0151] As described above, based on different measurement modes, the meaning of the nodes in the message forwarding path is different. For example, in the hop-by-hop measurement mode, the nodes in the message forwarding path refer to all the nodes in the message forwarding path, such as the message encapsulation node, the penetrating node and the message decapsulation node shown in Figure 1 In the end-to-end measurement mode, the nodes in the message forwarding path refer to the head node (i.e., the message encapsulation node) and the tail node (i.e., the message decapsulation node) in the message forwarding path.

[0152] In the embodiments of the present application, if the packet encapsulation node determines that the current measurement mode is the hop-by-hop measurement mode, the indication field is encapsulated in the first packet header in the traffic packet when the traffic packet in the service flow is encapsulated. In this way, the node in the packet forwarding path identifies that the indication field is encapsulated in the first packet header, and determines that it is the hop-by-hop measurement mode. Therefore, each node in the packet forwarding path needs to report IOAM data and measure network performance based on the indication of the indication field.

[0153] If the packet encapsulation node determines that the current measurement mode is the end-to-end measurement mode, the indication field is encapsulated in the second packet header in the traffic packet when the traffic packet in the service flow is encapsulated. In this way, the node in the packet forwarding path identifies that the indication field is encapsulated in the second packet header, and determines that it is the end-to-end measurement mode. Therefore, the intermediate penetrating node in the packet forwarding path does not need to report IOAM data and measure network performance based on the indication of the indication field, and only the packet encapsulation node and the packet decapsulation node need to report IOAM data and measure network performance based on the indication of the indication field.

[0154] The process of reporting IOAM data and measuring network performance based on the indication of the indication field can be referred to the description of the embodiments above, and will not be repeated here.

[0155] In one of the embodiments, the process of reporting IOAM data and measuring network performance based on the indication of the indication field comprises the following steps. Figure 2 As shown in the embodiment, the present embodiment relates to a process of reporting IOAM data and measuring network performance by the packet encapsulation node according to the indication field in the traffic packet encapsulating the indication field. The process comprises the following step A1.

[0156] In step A1, the packet encapsulation node reports IOAM data to the receiving entity according to the indication of the IOAM trace type field, performs packet loss measurement according to the indication of the packet loss measurement field, and performs delay measurement according to the indication of the delay measurement field.

[0157] The process of reporting IOAM data and measuring network performance by the packet receiving node according to the indication field in the traffic packet encapsulating the indication field can be referred to the process of reporting IOAM data and measuring network performance by the packet receiving node according to the indication field in the traffic packet encapsulating the indication field in the above, and will not be repeated here.

[0158] In one of the embodiments, referring to Figure 10 A packet processing method is provided for a packet receiving node in a packet forwarding path. As described above, the packet receiving node refers to a node other than the packet encapsulation node in the packet forwarding path. In the hop-by-hop measurement mode, the node other than the packet encapsulation node in the packet forwarding path can be Figure 1The illustrated penetration node and the message decapsulating node; in the end-to-end measurement mode, the nodes in the message forwarding path except the message encapsulating node can be the message decapsulating node.

[0159] Of course, the method for the message receiving node in the message forwarding path in the embodiments of the present application can also be used for the message encapsulating node, which is not repeated here.

[0160] The message processing method comprises:

[0161] Step 1001, the message receiving node receives the traffic message encapsulated with the indication field sent by the message encapsulating node in the message forwarding path.

[0162] The indication field comprises an IOAM trace type field, a packet loss measurement field, and a delay measurement field.

[0163] Step 1002, the message receiving node reports the IOAM data to the receiving entity according to the indication of the IOAM trace type field, performs packet loss measurement according to the indication of the packet loss measurement field, and performs delay measurement according to the indication of the delay measurement field.

[0164] In one of the embodiments, the indication field further comprises an extension flag field, and the message processing method further comprises: the message receiving node reports the flow identifier and the message sequence identifier in the message forwarding path to the receiving entity according to the indication of the extension flag field.

[0165] In one of the embodiments, the extension flag field comprises a plurality of bit positions, and the reporting of the flow identifier and the message sequence identifier in the message forwarding path to the receiving entity according to the indication of the extension flag field comprises: if the 0th bit position of the plurality of bit positions is set to a first value, the message receiving node reports the flow identifier to the receiving entity; if the 1st bit position of the plurality of bit positions is set to the first value, the message receiving node reports the message sequence identifier to the receiving entity.

[0166] In one of the embodiments, the IOAM trace type field comprises a plurality of bit positions, different bit positions correspond to different IOAM data types, and the reporting of the IOAM data to the receiving entity according to the indication of the IOAM trace type field comprises: the message receiving node determines the type of the IOAM data to be reported to the receiving entity according to the values of the bit positions in the IOAM trace type field; and the message receiving node reports the IOAM data corresponding to the type of the IOAM data to the receiving entity.

[0167] In one of the embodiments, the packet loss measurement is performed according to the indication of the packet loss measurement field, including: the packet receiving node determines the packet batch to which the traffic packet belongs according to the field value of the packet loss measurement field; and the packet receiving node reports the packet count value corresponding to each packet batch to the receiving entity according to the packet batch; wherein the field values of the packet loss measurement fields of the multiple continuous traffic packets belonging to the same packet batch are the same, and the field values of the packet loss measurement fields of the traffic packets belonging to different packet batches are different.

[0168] In one of the embodiments, the time delay measurement is performed according to the indication of the time delay measurement field, including: the packet receiving node determines the target traffic packet in which the time delay measurement field is set to the first value from the packet batch; and the packet receiving node reports the packet timestamp of the target traffic packet to the receiving entity, and prohibits reporting the packet timestamp of the other traffic packet in which the time delay measurement field is set to the second value to the receiving entity.

[0169] The implementation manners and beneficial effects of the packet processing method for the packet receiving node in the packet forwarding path described above can refer to the related descriptions in the implementation manners of the packet processing method for the packet encapsulating node, which will not be repeated here.

[0170] Next, the packet loss measurement and time delay measurement processes of the embodiments of the present application are exemplarily described.

[0171] 1) Packet loss measurement process

[0172] In the IPv6 network environment, in the process of encapsulating each traffic packet of the service flow by the packet encapsulating node based on different measurement modes, the indication field defined in the embodiments of the present application can be carried in the Hop-by-Hop option header or the Destination option header.

[0173] If it is the hop-by-hop measurement mode, the Hop-by-Hop option header is used, so that each hop node in the packet forwarding path needs to perform corresponding processing on the indication field; and if it is the end-to-end measurement mode, the Destination option header is used, so that only the packet encapsulating node and the packet decapsulating node in the packet forwarding path need to perform corresponding processing on the indication field.

[0174] Next, in the encapsulation process of the indication field, the Flow ID is allocated to the service flow. Exemplarily, the packet encapsulating node can randomly allocate the Flow ID or the centralized controller can uniformly allocate the Flow ID, wherein the random allocation of the Flow ID can cause the Flow ID repetition conflict, and the uniform allocation by the centralized controller is preferred.

[0175] The packet encapsulation node records the Flow ID field of the service flow, and for each traffic packet in the service flow, the bit value of the "L" field of each traffic packet is exchanged between 0 and 1 according to a fixed packet quantity or a fixed timer.

[0176] In this way, the receiving node only reads the marked value of the encapsulation to identify which batch the flow packet belongs to, all nodes in the packet forwarding path count the packets of each batch and report the packet count value of each batch to the receiving entity, and carry the Flow ID of the service flow, and the receiving entity can measure the packet loss occurring between any nodes by comparing the packet count values reported by different nodes in the packet forwarding path.

[0177] Please refer to Figure 5 Suppose that the traffic packets of a batch of measured service flow (measured service, i.e. service flow, assuming its Flow ID = 100) are counted in a certain measurement period, the packet encapsulation node and the first penetration node report the same packet count value, both 1000, but the second penetration node reports a packet count of 980, and the packet decapsulation node reports a packet count value of 970, then the receiving entity can accurately calculate the packet loss rate of the measurement period as: (1000-970) / 1000 = 3%, and determine that 20 packets are lost at the second penetration node and 10 packets are lost at the packet decapsulation node.

[0178] 2) Delay measurement (or called jitter measurement) process

[0179] As described above, the packet encapsulation node uses the "L" bit mark to generate alternating batch packets, and uses the "D" bit to generate single packet delay measurement in the batch. For each batch of packets, the packet encapsulation node determines the target traffic packet from each batch of packets, and then the packet encapsulation node sets the 1-bit position of the target traffic packet delay measurement field to 1, and sets the 1-bit position of the delay measurement field of the other packets in the packet batch to 0.

[0180] The receiving node identifies the target traffic packet with the D bit set in each batch, and records the time stamp of the target traffic packet as the packet time stamp, and the receiving node reports the packet time stamp of the D bit set to "1" packet of each batch to the receiving entity, and carries the Flow ID information of the service flow; the receiving entity can measure the delay value of the packet between any nodes by comparing the packet time stamps of the same packet reported by different nodes on the packet forwarding path.

[0181] It should be noted that the measurement of the delay requires that each node in the packet forwarding path maintains time synchronization. Please refer toFigure 7 Suppose that during a certain measurement period, the message encapsulation node performs a test on a certain batch of the service flow (the service flow being tested is the business flow itself). In a packet with ID=100, if the D bit is set to "1", the packet encapsulation node reports the packet to the receiving entity at a timestamp of 8:30:10:5 (hours:minutes:seconds:milliseconds). The intermediate traversing node reports the received packet with the D bit set to "1" at a timestamp of 8:30:10:7.5 (hours:minutes:seconds:milliseconds). The packet decapsulation node reports the received packet with the D bit set to "1" at a timestamp of 8:30:10:13.8 (hours:minutes:seconds:milliseconds). Using the timestamps reported by all nodes in the packet forwarding path associated with FlowID 100, the end-to-end latency for this measurement period can be accurately calculated as 13.8 - 5 = 8.8 milliseconds, and the latency from the packet encapsulation node to the traversing node is 7.5 - 5 = 2.5 milliseconds.

[0182] It should be understood that although the steps in the flowchart above are shown sequentially as indicated by the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowchart above may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the steps or stages in other steps.
