Protection is an important service level agreement (SLA) index of a small-granularity slice private line. However, in the case where both a primary path and a backup path of a small-granularity slice fail, a service cannot be forwarded to a destination node. SUMMARY

[0016] The second tunnel is configured for each SPN small-particle slice service; wherein

[0017] The priority of the second tunnel is higher than the priority of the first tunnel.

[0018] The second tunnel of the same SPN small-particle slice service comprises a primary channel and a backup channel.

[0019] In the above scheme, the first command carries information of the source node and information of the destination node corresponding to the source node.

[0024] Both the primary channel and the backup channel of the small-particle slice channel have not failed; wherein

[0025] The second tunnel represents a tunnel with high priority in a tunnel group corresponding to an out-interface of the first packet.

[0026] In the above scheme, one tunnel group is bound to one or more out-interfaces, and one tunnel group comprises tunnels with different priorities.

[0027] In the above scheme, one tunnel group comprises tunnels of different types, and the priorities of the tunnels of different types are different.

[0028] In the above scheme, one tunnel group comprises a multi-protocol label switching (MPLS) tunnel and a segment routing (SR) tunnel, and the priority of the MPLS tunnel is higher than the priority of the SR tunnel.

[0029] In the above scheme, the first information is determined by the server according to service requirements of the SPN small-particle slice service.

[0044] MTN is a new type of transport network technology system defined by the International Telecommunication Union-Telecommunication Sector (ITU-T) for new service requirements (for example, the requirement of network slicing), which can realize effective integration of TDM and packet switching; MTN is composed of a Section layer and a Path layer, and the Path layer is also referred to as a passage layer. The Section layer of MTN reuses a Flexible Ethernet (FlexE) logical support port binding, is compatible with an Ethernet underlying protocol stack and a standard Ethernet optical module; the Path layer of MTN supports TDM switching based on a 66-byte (B) code block, has a perfect end-to-end Operation Administration and Maintenance (OAM) mechanism, and supports cross-multiplexing of any Nx5G channelized customer signals.

[0045] With the development of services, MTN is also developing smaller granularity TDM channels, for example, 10-megabit per second (Mbps) granularity channels. Specifically, a Fine Granularity Unit (FGU) is used to further time slot division and multiplexing of a 5Gbps granularity channel of a Slicing Packet Network (SPN) Path layer, to form a small granularity channel with a bandwidth granularity of 10 Mbps.

[0046] Protection is an important SLA index of a small granularity slicing private line, and the MTN fine granularity Path (MTN FG Path) layer supports Automatic Protection Switching (APS). APS is a linear protection mechanism, and an APS protocol message is carried by an APS code block of the layer. The APS protection mechanism supports one-way / double one-way 1+1 path protection, and the 1+1 path can be understood as a main path and a backup path. Currently, only 1:1 or 1+1 protection can be provided when a small granularity slicing private line is established, but in the case that both the main path and the backup path of the small granularity slicing are faulty, the existing technical solution cannot provide protection for the small granularity slicing private line, and cannot forward the service to the destination node.

[0047] Based on this, in various embodiments of the present application, the source node of the SPN forwards the first packet by using a first tunnel in the case that the primary and backup channels of the small-granularity slice both fail; wherein the first tunnel represents a tunnel with a low priority in a tunnel group corresponding to an out-interface of the first packet. The above scheme can still forward the packet to the destination node in the case that the primary and backup channels of the small-granularity slice both fail, thereby improving the communication reliability. In addition, the above scheme only selects the tunnel for forwarding the packet according to the priority of the tunnel in the tunnel group corresponding to the out-interface of the packet at the source node, and has small network changes, so that the multi-point failure protection of important services can be implemented at a minimum cost.

[0048] The present application will be further described in detail below in combination with the drawings and embodiments.

[0049] The present application provides a packet processing method, which is applied to a source node of an SPN small-granularity slice service, and can also be referred to as a source node of the SPN. The source node of the SPN small-granularity slice service and the source node of the SPN are both SPN devices. As shown in the figure, the method comprises the following steps. Figure 1

[0050] Step 101: In the case that the primary and backup channels of the small-granularity slice both fail, a first tunnel is used to forward a first packet.

[0051] The first tunnel represents a tunnel with a low priority in a tunnel group corresponding to an out-interface of the first packet.

[0052] ​Here, the source node of the SPN small-granularity slice service acquires the first packet, detects whether the primary and backup channels of the small-granularity slice channel have failed, in the case where the primary and backup channels of the small-granularity slice channel have both failed, the tunnel of high priority in the tunnel group corresponding to the out interface of the first packet is invalid, a tunnel of low priority in the tunnel group corresponding to the out interface of the first packet is determined, a first tunnel is obtained, and the first tunnel is used to forward the first packet, so that the first packet is sent out through the out interface of the first packet; the first tunnel is in a normal working state, that is, the first tunnel is valid or the first tunnel has not currently failed, and can be used to forward a packet. The source node of the SPN small-granularity slice service can determine the tunnel group corresponding to the out interface of the first packet according to the following method: the out interface of the first packet is determined according to a forwarding table, or the out interface of the first packet is determined according to the destination address carried by the first packet; the tunnel group corresponding to the out interface of the first packet is determined according to a first relationship; the first relationship at least includes a corresponding relationship or a mapping relationship between the out interface and the tunnel group, and specifically, the first relationship can include a corresponding relationship or a mapping relationship between the identifier of the out interface and the number or identifier of the tunnel group. The first relationship can be stored in the source node of the SPN small-granularity slice service, or obtained by the source node of the SPN small-granularity slice service from a management and control system or a server corresponding to the management and control system.

[0053] The small-granularity slice channel can be understood as a channel of a small-granularity slice, and the primary and backup channels of the small-granularity slice channel can be understood as primary and backup channels of a small-granularity slice. The small-granularity slice can be understood as an SPN small-granularity slice, one small-granularity slice can have one primary channel and one backup channel, and one service with a hard isolation requirement corresponds to at least one small-granularity slice. The primary and backup channels of the small-granularity slice channel refer to the primary channel and the backup channel of the small-granularity slice channel, the primary channel of the small-granularity slice channel is also referred to as a small-granularity slice primary channel, and the backup channel of the small-granularity slice channel is also referred to as a small-granularity slice backup channel; the primary and backup channels can also be understood as primary and backup links or primary and backup paths. The first packet can be understood as any packet or any service packet or any management and control packet, and the first packet includes an SPN related packet, such as an SPN service packet or an SPN small-granularity slice service packet.

[0054] In an embodiment, one tunnel group corresponds to binding one or more out interfaces, and one tunnel group includes tunnels of different priorities.

[0055] Here, the source node of the SPN small-granularity slice service can select a tunnel for forwarding a packet according to the priority of the tunnel in the tunnel group corresponding to the out interface of the packet (service packet), so as to improve the communication reliability.

[0056] On the basis that one tunnel group corresponds to bind one or more outgoing interfaces, in an embodiment, one tunnel group contains different types of tunnels, and the priorities of different types of tunnels are different.

[0057] Here, different types of tunnels in the same tunnel group are distinguished by priority. The number of tunnels of the same type in the same tunnel group can be one or at least two, which can be established according to actual needs, and is not limited here. Different types of tunnels may support different transmission protocols, so that the appropriate tunnel can be selected in the tunnel group corresponding to the outgoing interface of the service message to forward the service message according to the transmission protocol supported by the service data or the service message, so as to improve the data transmission reliability. The service message carries service data.

[0058] On the basis that one tunnel group corresponds to bind one outgoing interface, in an embodiment, one tunnel group contains MPLS tunnels and SR tunnels, and the priority of the MPLS tunnel is higher than that of the SR tunnel.

[0059] Here, the SR tunnel can be a dynamic SR tunnel. The first tunnel can be a dynamic SR tunnel. That is, in the case that both the primary and standby channels of the small-grain slice channel fail, the first message can be forwarded by using the effective dynamic SR tunnel in the tunnel group corresponding to the outgoing interface of the first message. When forwarding the message by using the SR tunnel, the message is forwarded according to the packet forwarding mechanism. The effective dynamic SR tunnel can be understood as an SR tunnel in a normal working state and can be used to forward the message.

[0060] It should be noted that the MPLS tunnel can also be referred to as an MPLS-TP (MPLS-Transport Profile) tunnel; the SR tunnel or the dynamic SR tunnel can also be referred to as an SR-TP tunnel, and the SR-TP tunnel is suitable for SR-TP (MPLS-TP and SR combined) networking mode.

[0061] Table 1 gives an example of a tunnel group, which contains MPLS tunnels and SR tunnels in the same tunnel group.

[0062] Table 1

[0063]

[0064] Among them, the outgoing interface bound with the tunnel group 001 is port1; the MPLS tunnel in the same tunnel group is bound with the small-grain slice channel MTN-001, and the SR tunnel is not bound with the small-grain slice channel. The priority of the MPLS tunnel is higher than that of the SR tunnel.

[0065] In order to enable the source node of the SPN small-granularity slice service to select a suitable tunnel for packet forwarding according to the priority of the tunnels in the same tunnel group, in an embodiment, before the first tunnel is used to forward the first packet, the method further comprises:

[0066] receiving the first information and / or the second information issued by the server; wherein,

[0067] the first information is used to indicate the priority of the tunnels;

[0068] the second information is used to indicate that the source node of the SPN small-granularity slice service selects a tunnel for forwarding a packet according to the priority of the tunnels included in the tunnel group.

[0069] Here, the server can be understood as a management system or a server running the management system. The first information can indicate the priority of each tunnel established by the source node of the SPN small-granularity slice service, or indicate the priority of each type of tunnel established by the source node of the SPN small-granularity slice service. In actual application, an enumeration value can be used to define the priority of the tunnel, for example, enumeration values 00-07 are used to represent the priority of the tunnel, and the smaller the enumeration value, the lower the priority of the tunnel. The first information can be used to indicate that the priority of the MPLS tunnel is 07 and the priority of the SR tunnel is 01.

[0070] In the case where the first information and the second information are received, when the source node of the SPN small-granularity slice service receives any packet, it determines the tunnel group corresponding to the out-interface of the packet, and selects a tunnel with a higher priority to forward the packet according to the tunnels in the tunnel group corresponding to the out-interface of the packet that are in a normal working state. It should be noted that in the case where both the primary and backup channels of the small-granularity slice fail, the high-priority tunnel is disabled.

[0071] In an embodiment, the first information is determined by the server according to the service requirement of the SPN small-granularity slice service.

[0072] Here, the server can determine the priority of the tunnel according to the service requirement of the SPN small-granularity slice service, generate the first information according to the priority of the tunnel, and issue the first information to the source node of the SPN small-granularity slice service. The service requirement of the SPN small-granularity slice service can be understood as the SLA requirement or SLA demand of the service.

[0073] For example, the SPN small-granularity slice service includes a first service and a second service, in a case where the SLA requirement of the first service is higher and the SLA requirement of the second service is lower, the server can indicate, by the first information, a source node of the SPN to establish a tunnel group for the first service, establish a small-granularity slice channel corresponding to the service bearer, set a second tunnel bound with the small-granularity slice channel corresponding to the first service as a high priority, and set a first tunnel corresponding to the first service as a low priority. The second service does not establish a tunnel group, and only uses the corresponding small-granularity slice channel and / or the tunnel corresponding to the second service to bear the second service. The first service can be a premium class service, and the premium class service can include a control class service and / or a production class service, etc. The second service can be a high-class service, and the second service does not bind a tunnel group.

[0074] Before the server issues the first information and / or the second information, the source node of the SPN small-granularity slice service also needs to be instructed to establish a tunnel between the source node and the sink node. Based on this, in an embodiment, before the server issues the first information and / or the second information, the method further includes:

[0075] receiving a first command issued by the server, the first command being used to instruct to establish a tunnel group between the source node and the sink node of the SPN small-granularity slice service;

[0076] According to the first command, a tunnel group between the source node and the corresponding sink node is established.

[0077] In an embodiment, the first command is determined by the server according to the service requirement of the SPN small-granularity slice service.

[0078] Here, the source node of the SPN determines the sink node corresponding to the source node and establishes a tunnel group between the source node and the corresponding sink node in a case where the first command is received. One tunnel group can include tunnels of different priorities. One source node can correspond to one sink node, or can correspond to at least two sink nodes. In the SPN, the source node represents the starting point of service transmission, and the sink node represents the end point of service transmission.

[0079] One source node has at least one port, and the sink node also has at least one port, therefore, there is at least one tunnel group between one source node and one corresponding sink node, one tunnel group can correspond to the port of one sink node, each tunnel group has a tunnel group ID, and the tunnel group IDs of different tunnel groups are different, that is, different tunnel groups are distinguished by the tunnel group ID. The same tunnel group can include different tunnels, and when forwarding a packet, a suitable tunnel can be selected from different tunnels in the same tunnel group for packet forwarding according to the priority of the tunnel.

[0080] In actual application, the service and the tunnel group are one-to-one corresponding, and a tunnel group does not need to be established for all services, only a tunnel group needs to be established for a service with high SLA requirement, therefore, the server needs to determine the first command according to the service requirement of the SPN small-granularity slice service, and the service requirement of the SPN includes the SLA requirement.

[0081] Considering that the service with high SLA requirement has a corresponding relationship with the small-granularity slice channel, in actual application, the source node of the SPN small-granularity slice service can determine whether to bind the tunnel in the established tunnel group with the small-granularity slice channel corresponding to the service according to the SLA requirement of the service, in the case that the tunnel group between the source node and the corresponding sink node is successfully established. For example, in the case that the SLA requirement of the first service requires high quality of service, the high-priority tunnel in the established tunnel group can be bound with the small-granularity slice channel corresponding to the first service; in the case that the SLA requirement of the second service indicates that low quality of service can meet the requirement of the second service, the small-granularity slice channel corresponding to the second service can not be bound with a tunnel.

[0082] In order to facilitate the source node of the SPN small-granularity slice service to determine the corresponding sink node and improve the efficiency of the source node of the SPN small-granularity slice service to establish a tunnel group, in an embodiment, the first command carries the information of the source node and the information of the sink node corresponding to the source node.

[0083] Here, the source node of the SPN small-granularity slice service parses the first command to obtain the information of the source node and the information of the sink node corresponding to the source node carried by the first command, and establishes a tunnel group between the source node and the corresponding sink node based on the information of the source node and the information of the sink node corresponding to the source node.

[0084] In the case that the server respectively issues corresponding first commands to each source node in the SPN, the first command can carry the information of one source node in the SPN and the information of the sink node corresponding to the source node; the information of the source node carried in different first commands is different, and the sink nodes corresponding to different source nodes can be the same or different. The information of the source node includes the identifier of the source node, the Internet Protocol Address (IP address), etc.

[0085] In the case that the server broadcasts or group-sends the first command to multiple source nodes in the SPN, the broadcasted or group-sent first command carries the same content, at this time, the first command can carry the information of multiple source nodes in the SPN and the information of the sink node corresponding to each source node; the source node receiving the first command determines the information of the sink node corresponding to the source node from the first command, and establishes a tunnel group between the source node and the corresponding sink node.

[0086] To provide 1:1 or (1+1) protection for small-particle slices to improve the reliability of SPN small-particle slice services, in an embodiment, the method further comprises at least one of the following:

[0087] binding the second tunnel in the tunnel group established by the source node to a small-particle slice channel;

[0088] configuring a second tunnel for each SPN small-particle slice service; wherein,

[0089] the priority of the second tunnel is higher than the priority of the first tunnel;

[0090] the second tunnel for the same SPN small-particle slice service comprises a primary channel and a backup channel.

[0091] Here, in the case where the tunnel group established by the source node of the SPN small-particle slice service comprises the first tunnel and the second tunnel, the second tunnel in the tunnel group is bound to a small-particle slice channel corresponding to the out interface of the tunnel group. For example, in the case where the second tunnel is an MPLS tunnel, the MPLS tunnel can be bound to a small-particle slice channel after the MPLS tunnel is encapsulated with an MPLS label or an MPLS-TS label, such as being arranged in the small-particle slice channel. The small-particle slice channel can be understood as a channel of the small-particle slice service, including a primary channel of the small-particle slice service and / or a backup channel of the small-particle slice service.

[0092] The source node of the SPN small-particle slice service can correspondingly configure a second tunnel for each SPN small-particle slice service, and bind a pair of primary and backup channels to each second tunnel, so that the second tunnel for the same SPN small-particle slice service comprises a primary channel and a backup channel, thereby achieving primary and backup protection or providing FGU 1:1 / 1+1 protection for the SPN small-particle slice service. That is, one SPN small-particle slice service corresponds to one second tunnel, and one second tunnel has one primary channel and one backup channel. For example, in the case where the second tunnel is an MPLS tunnel, a pair of primary and backup channels is bound to one MPLS tunnel. In this way, even if the primary channel or the backup channel in the second tunnel fails, the second tunnel can still forward packets.

[0093] It should be noted that there is a one-to-one correspondence between SPN small-granularity slice services and tunnel groups. A tunnel group includes a first tunnel and a second tunnel. The first tunnel can be an SR tunnel, and the second tunnel can be an MPLS tunnel. The high-priority second tunnel corresponds to the small-granularity slice channel, and the high-priority second tunnel is configured with primary and backup protection. The low-priority first tunnel is not bound to a small-granularity slice channel. The primary channel can be understood as the primary channel for small-granularity slices, the primary small-granularity slice channel, the primary channel for small-granularity slice services, or the primary channel for the small-granularity slice channel corresponding to the small-granularity slice service. The backup channel can be understood as the backup channel for small-granularity slices, the backup small-granularity slice channel, the backup channel for small-granularity slice services, or the backup channel for the small-granularity slice channel corresponding to the small-granularity slice service.

[0094] It should be noted that the source node of the SPN small-granularity slice service can also bind MPLS tunnels and SR tunnels in the same tunnel group to the same small-granularity slice service. In this case, the MPLS tunnel of the same small-granularity slice service has a higher priority than the SR tunnel.

[0095] To ensure communication reliability, a second tunnel can be preferentially selected for message forwarding. Based on this, in one embodiment, the method further includes:

[0096] The first message is forwarded using a second tunnel if at least one of the following conditions is met:

[0097] The main channel for small particle slicing was not malfunctioning;

[0098] The primary channel of the small particle slicing channel failed, while the backup channel of the small particle slicing channel did not fail.

[0099] Neither the primary nor backup channels of the small particle slicing channel experienced any malfunctions; among them...

[0100] The second tunnel represents the high-priority tunnel in the tunnel group corresponding to the outgoing interface of the first message.

[0101] Here, as Figure 2 As shown, if the primary channel of the small-granularity slice channel does not fail, and / or the backup channel of the small-granularity slice channel does not fail, the source node of the SPN small-granularity slice service determines the available high-priority tunnel in the tunnel group corresponding to the outgoing interface of the first packet, obtains the second tunnel, and uses the second tunnel to forward the first packet, so that the first packet is sent out through the outgoing interface of the first packet. In this way, small-granularity slice channel layer protection can be achieved.

[0102] In a case where the primary channel of the small-particle slice channel fails and the backup channel of the small-particle slice channel does not fail, the source node of the SPN small-particle slice service performs APS, the primary channel of the small-particle slice channel fails, and the backup channel of the small-particle slice channel takes effect, at this time, the second tunnel can be bound to the backup channel of the small-particle slice service, or can not be bound to the backup channel of the small-particle slice service.

[0103] In a case where the primary channel of the small-particle slice channel does not fail, the primary channel of the small-particle slice channel takes effect, and the backup channel of the small-particle slice fails, the second tunnel can be bound to the primary channel of the small-particle slice service, or can not be bound to the primary channel of the small-particle slice service.

[0117] The priority of the second tunnel is higher than that of the first tunnel.

[0118] The second tunnels for the same SPN small-granularity slice service include a primary channel and a backup channel.
