Detailed ways

First, the principle of packet coloring involved in the embodiments of the present application is briefly described. In the standard RFC8321, a technology is provided to detect delay, packet loss and jitter along the flow by adding color bits in the packet. Please refer to FIG. 1 , which is a schematic diagram of an application scenario of packet detection. As shown in Figure 1, the dyeing technology specifies a dyeing cycle for the device. The number of packets included in each dyeing cycle is the same. Device 1 (the head node) alternately dyes the packets according to the cycle change. Affected by the network environment, the order in which the packets leave device 1 and the order in which they arrive at device 2 may be different during packet transmission. The packets are detected, and the number of packets included in the statistics period can be more than the number of packets in the dyeing period.

Device 2 can count the number of packets included in the same dyeing cycle in a statistical period, that is, perform packet statistics operation, and report the statistical results to the analyzer, so that the analyzer can determine the packet loss situation. As shown in FIG. 1 , device 2 detects three No. 1 packets in Rx[i+1]. The analyzer can know that packet loss occurs according to the fact that Tx[i+1] contains 4 No. 1 packets and Rx[i+1] contains 3 No. 1 packets.

When the device 1 dyes a certain message in a dyeing cycle, it can also record the time stamp of the message, that is, perform a time stamping operation, and report the operation result to the analyzer. Device 2 can also perform a time stamping operation on the packet when receiving the packet, and report the operation result to the analyzer. The analyzer can determine the delay of the packet according to the time corresponding to the two timestamps. The analyzer can also combine the time stamp information of multiple packets on different devices to analyze the jitter situation.

According to the packet structure of different forwarding layers, there are currently multiple coloring protocols to color different packets. The following briefly describes the existing packet processing methods.

Please refer to FIG. 2 , which is a schematic diagram of an application layer scenario of a packet processing method. As shown in Figure 2, there is a flow that flows into the wide area network (WAN) through the campus, and the WAN side uses SR tunnel encapsulation. Since the forwarding layer protocol used by device 1 to device 3 is IPv4, the coloring protocol corresponding to IPv4 is used. The forwarding layer protocol used by device 4 and device 5 is SRv6, and the iFIT coloring method is adopted. The device 4 needs to report the operation results to the analyzer twice according to the two dyeing methods. Based on this, the analyzer can only detect this traffic in the stage of transmission from device 1 to device 4 according to the information reported by device 1 and device 4 based on the coloring protocol corresponding to IPv4. And/or according to the information reported by the device 4 and the device 5 based on the iFIT dyeing protocol, the traffic is detected during the transmission stage of the device 4 and the device 5 . To put it simply, the analyzer can only perform segment detection on this traffic, and cannot implement end-to-end hop-by-hop quality diagnosis from device 1 to device 5.

In the packet processing method shown in Figure 3, although end-to-end hop-by-hop quality detection can be implemented, new problems will be introduced. As shown in FIG. 3 , in this packet processing method, whether IPv4 or SRv6 is used as the forwarding layer protocol, the packet is dyed by using a coloring protocol corresponding to IPv4. Since IPv4 packets enter the WAN, the packet will be encapsulated with an outer layer, so that the coloring information is located in the inner layer of the packet. When device 4 and device 5 obtain the coloring information, they need to parse the inner layer of the packet. layer, which reduces the forwarding efficiency.

The packet processing method provided by the embodiment of the present application can solve the above problem. The following briefly describes the system architecture of the packet processing method provided by the embodiments of the present application. Please refer to FIG. 4a. FIG. 4a is a schematic diagram of a system architecture of a packet processing method provided by an embodiment of the present application. As shown in Fig. 4a, the message processing system may include one analyzer and multiple network devices (device 1 to device 5). The forwarding layer protocol used by the network devices (device 1 to device 3) in the campus is IPv4, and the packets are dyed based on the dyeing protocol corresponding to IPv4. The forwarding layer protocol used by the network devices (device 4 and device 5) in the WAN is SRv6, and the iFIT-based coloring protocol is used to color packets. Optionally, device 4 and device 5 may serve as network-side edge devices (provider edge, PE).

For the traffic transmitted from the device 1 to the device 5, the device 4 can map the IPv4 coloring information corresponding to the selected traffic to the coloring bits defined by the iFIT protocol according to the policy. Similarly, corresponding to the traffic transmitted from device 5 to device 1, device 4 can map the SRv6 coloring information corresponding to the selected traffic to the coloring bits defined by the coloring protocol corresponding to IPv4 according to the policy.

Device 1 to Device 5 can also perform packet statistics operations and/or time stamping operations on the packets according to their respective dyeing protocols, and then report the operation results to the analyzer according to the unified data format, so that the analyzer can perform operations according to the operation results. Packet loss, delay and/or jitter detection of packets.

Optionally, device 1 to device 5 may also report traffic identifiers to the analyzer, so that the analyzer can perform path restoration according to the traffic identifiers.

Optionally, there are various situations in the park. It can be an office building or a factory. In addition, it can also be other scenarios, such as an orchard, a campus, etc., which are not limited here.

Device 1 to Device 5 are devices capable of forwarding IP packets, which can be routers or switches. In addition, they can also be other devices capable of forwarding IP packets, such as firewalls, which are not described here. limited. Each device may be the same device or different devices, which are not specifically limited here.

Optionally, in this embodiment of the present application, there may be multiple devices capable of mapping dyeing information in the message processing system. As shown in FIG. 4b , devices 4 to 8 can map dyeing information.

The packet processing method provided in this embodiment of the present application may be applied to the system architecture shown in FIG. 4a or 4b. Next, the packet processing method provided by the embodiment of the present application will be described. Please refer to FIG. 5 . FIG. 5 is a schematic flowchart of the packet processing method provided by the embodiment of the present application, including:

501. Obtain coloring information of a first packet, where the first packet corresponds to a first forwarding layer protocol.

The packet processing method provided in the embodiment of the present application is applied to a network device connecting two different forwarding layer protocols, that is, the device 2 shown in FIG. 6 . Taking the traffic transmitted from the device 1 to the device 3, and the device 1 is the start node and the device 3 is the end node as an example, the packet processing method provided by the embodiment of the present application will be described.

As the starting node, the device 1 can color the first packet according to the first coloring protocol corresponding to the first forwarding layer protocol for the specified traffic. Specifically, according to the first coloring protocol, color bit coloring of packet loss and delay is performed on the first packet. The device 1 may also perform packet statistics and/or time stamping operations according to the dyeing information, and report the obtained operation results to the analyzer.

Optionally, there are multiple possibilities for the first forwarding layer protocol, which can be MPLS or GRE, or VxLAN or IPv4. In addition, it can also be other forwarding protocols that can define packet formats, such as IPv6 or SRv6. , which is determined according to actual application requirements, which is not specifically limited here.

Optionally, the first coloring protocol is related to the first forwarding layer protocol, and there are many possibilities. If the first forwarding layer protocol is any one of MPLS, GRE, VxLAN, IPv6, and SRv6, the first coloring protocol It may be iFIT or iOAM. Besides, it may also be other dyeing protocols applicable to the first forwarding layer protocol, such as INT, which is not specifically limited here. If the first forwarding layer protocol is IPv4, the first coloring protocol may be IPCA, or may be other coloring protocols applicable to IPv4, such as IPFPM, which is not specifically limited here.

In the embodiment of the present application, there are various first forwarding layer protocols, which can be selected according to the needs of practical applications. In the case where the first forwarding layer protocol is determined, there are various options for the first coloring protocol, which improves the technical solution of the present application. flexibility and achievability.

Exemplarily, when the first forwarding layer protocol is IPv4, a coloring protocol based on IPv4 (for example, the IPFPM coloring protocol) can be used for bit 0 (Bit0) in the Flag field, or No. 6 or No. 7 in the ToS field. Bits (Bit6/7) are colored. Figure 7 shows the packet header of the colored IPv4 packet. In practical applications, the IPFPM dyeing protocol may also dye other positions in the IPv4 packet header, for example, any of bits 4 to 6 in the ToS field, which is not specifically limited here.

Exemplarily, when the first forwarding layer protocol is MPLS or IPv6 and the like, which has a multi-layer protocol capable of flexibly adding information in the packet header, the newly added packet header can be colored based on the iFIT coloring protocol. As shown in FIG. 8 , a packet header IFIT may be added to the MPLS packet, and the fields in the packet header can be colored. After coloring, the bold L field is used for packet loss coloring marking; the bold D field is used for delay coloring and jitter analysis.

When receiving the first packet, the network device may determine the first coloring protocol corresponding to the first forwarding layer protocol based on the first forwarding layer protocol corresponding to the first packet, so as to obtain coloring information of the first packet.

Optionally, the network device may receive multiple packets corresponding to different traffic flows, and the network device may select the first packet corresponding to the traffic to be detected according to the traffic selection policy configured by the network device. Since the traffic selection strategy is not the focus of the present invention, it will not be described here.

502. Convert the first packet into a second packet, where the second packet includes coloring information, and the second packet corresponds to the second forwarding layer protocol.

After determining the coloring information of the first packet, the network device may convert the first packet into the second packet, and map the coloring information to the second packet. Specifically, the second coloring protocol corresponding to the second forwarding layer protocol may be determined according to the second forwarding layer protocol. Then, the second packet is constructed according to the second forwarding layer protocol, the coloring bit of the second packet is determined based on the second coloring protocol, and the coloring information of the first packet is mapped to the coloring bit of the second packet.

It should be noted that the second packet and the first packet correspond to the same traffic, but the forwarding layer protocol and the coloring protocol used are different. That is to say, the first packet and the second packet are a traffic Packets in different formats corresponding to different forwarding layer protocols.

Optionally, there are multiple possibilities for the second forwarding layer protocol, which can be MPLS or GRE, or VxLAN or IPv4. In addition, it can also be other forwarding protocols that can define packet formats, such as IPv6 or SRv6. , which is determined according to actual application requirements, which is not specifically limited here.

Optionally, the second coloring protocol is related to the second forwarding layer protocol, and there are multiple possibilities. If the second forwarding layer protocol is any one of MPLS, GRE, VxLAN, IPv6, and SRv6, the second coloring protocol It can be iFIT or iOAM, and other dyeing protocols that can be applied to the second forwarding layer protocol, such as INT, are not limited here. If the second forwarding layer protocol is IPv4, the second coloring protocol may be IPCA, or may be other coloring protocols applicable to IPv4, such as IPFPM, which is not specifically limited here.

In the embodiment of the present application, there are various second forwarding layer protocols, which can be selected according to actual application needs. In the case where the second forwarding layer protocol is determined, there are various options for the second coloring protocol, which improves the technical solution of the present application. flexibility and achievability.

Optionally, in the relatively common interaction process of forwarding layer protocols, the strategy for mapping the coloring information by the network device may be preset. Among them, the common forwarding layer protocol interaction may be IPv4 and SRv6, or IPv4 and VxLAN, and other situations, such as IPv4 and IPv6, are not limited here.

503. Send the second message.

After constructing the second packet, the network device may send the second packet to the next-hop device.

Further, in different forwarding layer protocols, the packet uses a coloring protocol corresponding to the forwarding layer protocol, so that the network device can obtain the coloring information without parsing the packet memory, which improves the forwarding efficiency.

Optionally, in step 501, the network device may also acquire the traffic identifier corresponding to the first packet. In different forwarding layer protocols, network devices acquire traffic identifiers in different ways. Exemplarily, if the first packet is an IPv4 packet, the network device may determine the traffic identifier according to the quintuple information carried in the first packet. In addition, the network device may also determine the traffic identifier corresponding to the first packet based on other methods, for example, according to triplet information corresponding to the first packet. There is no specific limitation here. If the packet header of the first packet is an MPLS packet, the "Flow ID" field in the packet header can represent the flow identifier. In addition, the network device may also determine the traffic identifier of the first device according to other information carried in the MPLS packet, such as quintuple or triplet information carried in the MPLS packet, which is not specifically limited here. The manner in which the network device obtains the traffic identifier is related to the forwarding layer protocol, and can be selected according to the needs of the actual application, which is not specifically limited here.

Optionally, in step 501, the network device may perform a packet counting operation and/or a time stamping operation on the first packet according to the first coloring protocol to obtain the first operation result.

Optionally, in step 502, the network device may perform a packet counting operation and/or a time stamping operation on the second packet according to the second coloring protocol to obtain a second operation result.

It should be noted that which dyeing protocol the network device chooses to perform the packet statistics operation and/or the time stamping operation is related to the processing complexity of the dyeing protocol. In order to save computing resources, network devices often choose a dyeing protocol with simpler operations as the basis for packet statistics operations and/or time stamping operations. For example, in the SRv6 forwarding layer protocol, select the iFIT dyeing protocol, i.e. iFIT for SRv6; In the VxLAN forwarding layer protocol, select the iFIT dyeing protocol, i.e. iFIT for VxLAN; in addition, you can also choose other options, such as the IPCA dyeing protocol in the IPv4 forwarding layer protocol, which is not limited here.

Optionally, after step 502, the network device may also report at least one of the first operation result and the traffic identifier, or at least one of the second operation result and the traffic identifier to the analyzer, so that the analysis performs packet loss. At least one of detection, delay detection, jitter detection, and path restoration.

It should be noted that when each network device in the same packet processing system reports detection information to the analyzer, a unified format can be adopted, which is convenient for the analyzer to analyze and detect. The detection information includes at least one of an operation result and a traffic identifier, and the operation result includes a first operation result or a second operation result.

In this embodiment of the present application, the network device can report the operation result to the analyzer, so that the analyzer can perform packet loss, delay and jitter detection according to the operation result. At the same time, the network device can also report the traffic identifier, so that the analyzer can restore the forwarding path of the packet according to the traffic identifiers reported by the multiple network devices. In addition, the network device can select the coloring protocol based on which packet statistics and time stamping operations are performed on the packets, which improves the flexibility of the technical solution of the present application.
