Abstract
Description
Technical Field
[0001] This specification relates to the field of communication technologies, and in particular, to a method for sending packets and a network device. Background Art
[0002] As Figure 1 shown, in an EERN (Enhanced Ethernet Ring Network), all services share the bandwidth resources of the same physical ring network and cannot be dynamically adjusted according to the priorities and requirements of services, resulting in low resource utilization. The traffic between different services is mixed, and there is no effective isolation mechanism. The congestion or failure of one service may affect the normal operation of other services. As the network scale expands, the scalability of a single physical ring network is limited. When adding new services or devices, the entire network needs to be re-planned, increasing the operation and maintenance complexity. Summary of the Invention

[0035] The enhanced Ethernet Ring technology is a new technology developed based on the standard IEEE802.17 protocol, integrating the intelligence of IP, the economy of Ethernet, and the high bandwidth and high reliability of SONET / SDH, providing an efficient and flexible IP network solution.
[0036] The enhanced Ethernet Ring is an Ethernet transmission technology operating at Layer 1.5. It integrates the full-stack Ethernet in its architecture, naturally inherits Ethernet services, and provides a highly reliable transparent transmission platform for full-stack Ethernet services. The enhanced Ethernet Ring supports sub-millisecond slicing performance, is completely decoupled from services, and provides enhanced functions such as ring-level QoS and load balancing.
[0037] Currently, as Figure 1 shown, the enhanced Ethernet Ring adopts a reverse dual-ring structure, and data is forwarded between stations along the ring. Among them,
[0038] Ring 0: In the dual-ring of the enhanced Ethernet Ring, the ring in which the data frame transmission direction is clockwise is called Ring 0, also known as the Outer Ring.
[0039] Ring 1: In the dual-ring of the enhanced Ethernet Ring, the ring in which the data frame transmission direction is counterclockwise is called Ring 1, also known as the Inner Ring.
[0040] Station: The device on the enhanced Ethernet Ring, responsible for receiving and forwarding data frames.
[0041] Link: A unidirectional channel connecting adjacent stations.
[0042] Span: The link between two adjacent stations on the enhanced Ethernet Ring, consisting of two links with opposite directions.
[0043] West interface: The physical interface that receives data frames on Ring 0 and sends data frames on Ring 1.
[0044] East interface: The physical interface that sends data frames on Ring 0 and receives data frames on Ring 1.
[0045] Edge: When a segment or the station adjacent to the segment fails, the segment cannot forward data and becomes an edge.
[0046] Ring state: Divided into closed loop and open loop. A ring without edges is a closed loop, and a ring with edges is an open loop.
[0047] Currently, since all services share the bandwidth resources of the same physical ring network, dynamic adjustment cannot be performed according to the priorities and requirements of services, resulting in low resource utilization. The traffic between different services is mixed, and there is no effective isolation mechanism. The congestion or failure of one service may affect the normal operation of other services. As the network scale expands, the scalability of a single physical ring network is limited. When adding new services or devices, the entire network needs to be re-planned, increasing the operation and maintenance complexity.
[0048] To solve the above technical problems, embodiments of the present disclosure provide a method for sending a message. The method is applied to an Enhanced Ethernet Ring Network (EERN), as Figure 2 shown. The method includes:
[0049] S201 Obtain the message to be sent, and obtain the first attribute information of the message to be sent;
[0050] S202 Use the first attribute information to match the corresponding relationship, and obtain the first slice forwarding interface corresponding to the first attribute information;
[0051] S203 Send the message to be sent through the first slice forwarding interface;
[0052] Wherein, the corresponding relationship records the corresponding relationship between each attribute information and the slice forwarding interface.
[0053] In this embodiment, the administrator can first configure the corresponding relationship between the attribute information of the message and the slice forwarding interface. In this embodiment, the attribute information of the message can be the forwarding information of the message. For example, it can be one or a combination of VLAN information, VSI information, VXLAN information, and DSCP information.
[0054] In this embodiment, the administrator can use the main interface corresponding to the EERN logical sub-interface as the slice base interface for the encapsulation and forwarding of network slice messages. The EERN logical sub-interface is used as the slice forwarding interface for the forwarding of specific network slice channels. That is, the physical ring of the EERN is sliced into multiple logical rings, and each logical ring independently allocates bandwidth resources according to requirements. The services between each logical ring are isolated from each other, realizing the integrated deployment of multiple service rings.
[0055] The soft slice function is supported on the EERN logical sub-interface, and the sliced bandwidth and network slice channel ID are configured. Each sub-interface configures a network slice channel, and each channel corresponds to a corresponding Slice Id. Bandwidth resources are independently allocated between each channel to achieve service isolation.
[0056] In this embodiment, the administrator can also add a Slice Id identifier, which corresponds to different slice interfaces through the Slice Id identifier. It can also be understood that different slice interfaces are represented by the SliceId identifier.
[0057] Finally, the administrator can configure the correspondence between the attribute information of each message and the SliceId identifier.
[0058] In one example, the ATD frame in the EERN control frame can broadcast multiple attributes of the local site at the same time. Define the following attributes in the custom field of the ATD frame:
[0059] The slice bandwidth of each logical sub-interface and the corresponding SliceId, and establish the corresponding relationship.
[0060] Specifically, (1) Configure the slice bandwidth information for each logical sub-interface and broadcast it through the ATD frame.
[0061] (2) After the device receives the ATD frame, parse the slice bandwidth and Slice Id information in it, and update the local slice bandwidth table.
[0062] (3) The device adds up the bandwidths of the sites with the same Slice Id according to the Slice Id attribute in the received ATD frame to obtain the total bandwidth of the slice ring.
[0063] (4) Notify the total bandwidth of the slice ring to the corresponding EERN logical sub-interface as the slice queue rate limit and use the A0 bandwidth.
[0064] (5) The remaining bandwidth on the ring is used as the default slice bandwidth for forwarding through the default slice channel.
[0065] For example, in one example, the bandwidth occupied by slice ring 1 is 1G + 2G + 4G = 7G; the bandwidth occupied by slice ring 2 is 1G + 1G + 3G = 5G; the bandwidth occupied by slice ring 3 is 1G + 5G + 4G = 10G; the remaining bandwidth on the ring is used as the default slice bandwidth.
[0066] In this embodiment, when the network device receives a message to be forwarded, it obtains the first attribute information of the message to be sent through step S201. For example, obtain the VLAN information of the message to be forwarded (in other embodiments, it can also be other attribute information, which is defined according to the administrator's requirements here), query the above corresponding relationship through the VLAN information, and obtain the first SliceId corresponding to the first attribute information.
[0067] In this embodiment, after obtaining the first Slice Id according to the above method, when encapsulating in EERN, encapsulate the first SliceId attribute of the message.
[0068] The network device looks up the MAC address table according to the destination MAC address of the packet, and the EERN logical interface of the destination site matched is the slice basic interface.
[0069] When querying whether there is a network slice channel corresponding to the SliceId carried in the network slice packet on the slice forwarding interface of the slice basic interface, the following two situations may occur.
[0070] One: If the corresponding slice forwarding interface is not found or there is no corresponding network slice channel on the slice forwarding interface, the device defaults to ignoring the first SliceId carried in the packet and routes through the default slice channel.
[0071] Two: If the corresponding slice forwarding interface is found, that is, the first Slice Id carried in the packet is the same as the network slice channel ID configured on the slice forwarding interface, the network slice packet will be forwarded through the network slice channel on this slice forwarding interface.
[0072] Based on the above embodiments, the present disclosure also provides an example of packet forwarding, as Figure 3 shown:
[0073] The network device of EERN receives the upper-ring packet, queries the corresponding relationship according to the first attribute information (VLAN / VSI / VXLAN / DSCP) of the data packet, obtains the corresponding Slice Id, and encapsulates the Slice Id into the EERN packet.
[0074] Find the destination site according to the destination MAC address of the EERN packet. When a forwarding interface of the slice is found, check whether the channel ID of the slice interface matches the Slice Id carried in the EERN of the packet. If it matches, forward through the network slice channel on this slice forwarding interface; if it does not match, forward through the default slice channel.
[0075] It can be seen from the above embodiments that by slicing a physical ring into multiple logical rings and corresponding different slices through Slice Id, different packets can be forwarded through the slices corresponding to the Slice Id, realizing independent allocation of bandwidth resources for each logical ring, isolation of services between each logical ring, and realizing the integrated deployment of multiple service rings.
[0076] Based on the above method embodiments, the embodiments of the present disclosure also provide a network device. The network can be a routing device, a switching device, etc. The network setting enables the enhanced Ethernet ring network EERN. The network device includes:
[0077] An obtaining module, configured to obtain a packet to be sent and obtain the first attribute information of the packet to be sent;

[0080] Wherein, the corresponding relationship records the corresponding relationship between each attribute information and the slice forwarding interface.
[0081] Wherein, the first attribute information includes one or a combination of the following: VLAN information, VSI information, VXLAN information, and DSCP information.

[0084] Wherein, the matching module is specifically configured to obtain a first SliceId corresponding to the first slice forwarding interface.
[0085] Wherein, the sending module is specifically configured to encapsulate the obtained first SliceId in the message to be sent, and send the message to be sent encapsulated with the first SliceId through the first slice forwarding interface corresponding to the first SliceId.
