[0035] The following will describe the technical solutions in the embodiments of the present application in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0036] It should be noted that in the embodiments of the present application, the term "and / or" is only a description of the association relationship of the associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the embodiments of the present application, the character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0037] In the description of the embodiments of the present application, the term "corresponding" may indicate a direct or indirect correspondence between two items, or an association relationship between the two items, or a relationship between indication and being indicated, configuration and being configured, and the like.

[0038] To facilitate understanding of the technical solutions of the embodiments of the present application, the relevant technologies of the embodiments of the present application are described below. The following related technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all belong to the protection scope of the embodiments of the present application.

[0039] In related technologies, networking is done in the following three ways:

[0040] The first one: Infiniband. Infiniband networking is the optimal solution for high-performance networks. It uses ultra-high bandwidth and a credit-based mechanism to ensure zero congestion and ultra-low latency. The dedicated network protocol stack tailored by IBTA for RDMA can ensure the reliability of data transmission at the hardware level, relying on the data link layer (IB Link Layer) to achieve flow control and reliable low-latency transmission. A dedicated IB network card and IB switch are required.

[0041] The second type: frame cluster. It is a network device with independent main control board, business board, power module, fan module, etc., and comes with an external frame. Each device is connected in a cluster to form a multi-level and multi-plane system, enabling it to work together.

[0042] The third type: DDC. DCC is a distributed decoupled chassis device solution. The service line card acts as the front end and becomes the NCP (Network Cloud Packet (Line card in Chassis)) role, and the switching network board acts as the back end and becomes the NCF (Network Cloud Fabric (Fabric card in Chassis)) role. The original connector components between the two are now replaced by optical fiber cables, and forwarding supports cell switching.

[0043] However, the above-mentioned related technologies still have the following technical problems:

[0044] 1. IB Network

[0045] Using ultra-high bandwidth and a credit-based mechanism to ensure zero congestion and ultra-low latency is several times more expensive than traditional Ethernet networking at the same bandwidth. It is costly, slow to evolve, and difficult to maintain.

[0046] 2. Frame Cluster

[0047] The expansion capability is limited, the frame size limits the maximum number of ports, the equipment consumes a lot of power, the cabinet power requirements are high, the number of ports on a single device is large, and the fault domain is large.

[0048] 3. DDC

[0049] DDC technology is closed, and line cards and switching network boards must use Broadcom chips, which makes it impossible for end users to have a second source of supply. In addition, DDC requires line cards and switching network cards to support cell switching, which has high cost and technical requirements.

[0050] Figure 1 Schematic diagram of the implementation process of the networking method provided in the embodiment of the present application Figure 1 ,like Figure 1 As shown, an embodiment of the present application provides a networking method, which is applied to a line card, and the method includes the following steps:

[0051] Step 101: Receive multiple first data packets; the multiple first data packets are data packets sent by a first device to a second device.

[0052] In actual application, the first device and the second device may be virtual machines or other devices, and this application does not limit this.

[0053] In actual application, the line card can be an independent box switch or router device, or other devices, which is not limited in this application.

[0054] Step 102: Assemble the multiple first data packets to obtain at least one first data packet group, each of which includes one or more first data packets.

[0055] The messages in the data packet group are only virtually reassembled, so the order of the messages remains unchanged.

[0056] The message in the data packet group carries at least one of the following information: first information, second information and third information; wherein,

[0057] The first information represents the number of the data packet group to which the data packet belongs;

[0058] The second information indicates whether the data packet is the starting data packet of the data packet group to which the data packet belongs;

[0059] The third information indicates whether the data packet is the end data packet of the data packet group to which it belongs.

[0060] refer to Figure 2 , Figure 2 The schematic diagram of the combination and restoration of Packet groups provided in the embodiment of the present application. Packet groups are based on the virtual reorganization and restoration technology of data packets. The incoming line card needs to support combination, and the outgoing line card needs to support restoration. The incoming line card LC side implements the assembly of messages, and the outgoing line card LC side implements the separation of messages. Packet group is a logical fixed-length message, such as 10000, which can be uniformly agreed upon according to the chip and device conditions. Packet group1, Packet group2 and Packet group3 are three data packet groups, Figure 2 Packet group 1, Packet group 2 and Packet group 3 can be arranged to be sorted and restored with sequence numbers. The sorting and restoration can be done with the help of the original message. For example, refer to Figure 3 , Figure 3 The schematic diagram of the location of the Packet group information in the VXLAN message provided in the embodiment of the present application, taking the VXLAN message as an example, the reserved bits in the VXLAN header can store the Packet group number, the start and end information of the Packet group message. By querying the Packet group number of the message, the order of the entire large packet can be obtained. The First of group and Last of group can be used to determine whether the message is the start message and the end message in the package; wherein the Packet group number corresponds to the first information, and the First of group and Last of group correspond to the second information and the third information respectively. Reference Figure 4 , Figure 4The schematic diagram of the location of the Packet group information in the SRv6 message provided in the embodiment of the present application, the reserved bit in the SRv6 header can store the Packet group number, the start and end information of the Packet group message. The order of the entire large packet can be obtained by querying the Packet group number of the message. The First of group and Last of group can be used to determine whether the message is the start message and the end message in the package; wherein the Packet group number corresponds to the first information, and the First of group and Last of group correspond to the second information and the third information respectively.

[0061] Step 103: Distribute the at least one first data packet group to at least one first switching device through a load balancing algorithm, so that the at least one first data packet group is forwarded to at least one second line card through the at least one first switching device.

[0062] In some optional implementations, distributing the at least one first data packet group to at least one first switching device through a load balancing algorithm includes:

[0063] Obtain the load connection diagram of the line card and the switching equipment;

[0064] selecting a distribution link for the at least one first data packet group based on the load condition connection map;

[0065] According to the distribution link, the at least one first data packet group is distributed to at least one first switching device.

[0066] In actual application, the line card can obtain the load connection diagram between the line card and the switching device by itself; it can also obtain the load connection diagram between the line card and the switching device through an external control device. By obtaining the load connection diagram between each line card and each switching device through an external control device, energy consumption and resources of the line card can be saved.

[0067] In some optional embodiments, the load condition connection diagram is obtained by traffic marking the connections between the line card and the switching device in the first connection diagram based on the traffic interval and the first traffic, wherein the first connection diagram is drawn based on the connection relationship between the line card and the switching device, and the first traffic includes the traffic from the line card to the switching device and / or the traffic from the switching device to the line card.

[0068] The second line card is one of the at least one second line card connected to the second device.

[0069] Exemplary, reference Figure 5 and Figure 6 , Figure 5 The network diagram provided in the embodiment of the present application Figure 1 , Figure 6 A schematic diagram of data forwarding provided in an embodiment of the present application. Figure 6 In the example, Ingress LC is an incoming line card connected to the first device, and EgressLC is an outgoing line card connected to the second device. After the incoming line card receives the data packet sent by the first device, it obtains the connection relationship between each line card and each switching device, and draws a connection diagram based on the connection relationship between each line card and each switching device to count the bidirectional traffic between each line card and each switching device; sets a traffic interval, and based on the traffic interval and the bidirectional traffic between each line card and each switching device, marks the connection between each line card and each switching device in the connection diagram to generate a load condition connection diagram between each line card and each switching device; selects the distribution link of at least one data packet group based on the load condition connection diagram, and distributes the at least one data packet group to the switching device on the distribution link. The switching device then forwards the data packet to the outgoing line card corresponding to the second device, and the outgoing line card restores the data packet and sends it to the second device.

[0070] In some implementations, the load conditions are divided into three levels, with a green line for message volume below 60%, a yellow line for message volume between 60% and 80%, and a red line for message volume above 80%.

[0071] Exemplary, reference Figure 5 , Figure 5In the figure, LC1, LC2, LC3, and LC4 are line cards, and FE1, FE2, FE3, and FE4 are switching devices. Exemplarily, VM1 is connected to LC1, and VM2 is connected to LC2. When VM1 wants to send data to VM2, VM1 sends multiple first data packets to LC1, and LC1 stores the first data packets. LC1 obtains a load condition connection diagram. In this embodiment, the paths of data sent from LC1 to LC2 include LC1-FE1-LC2, LC1-FE2-LC2, LC1-FE3-LC2, and LC1-FE4-LC2. LC1 selects a link to send a first space request message through a load balancing algorithm. Exemplarily, if the selected sending link is LC1-FE1-LC2, the first space request message is forwarded to LC2 via FE1. After LC2 receives the first space request message, LC2 calculates whether VM2 has cache space to process the data that VM1 wants to send to VM2. If VM2 has The cache space processes these data, LC2 sends a first space request response message to FE1 to inform VM2 that it has cache space to process the data, FE1 forwards the first space request response message to LC1, after LC1 receives the first space request response message, LC1 assembles the first data packet sent by VM1 to obtain at least one first data packet group, and selects a distribution link for at least one first data packet group through a load balancing algorithm. Exemplarily, the paths LC1-FE1-LC2, LC1-FE2-LC2, and LC1-FE3-LC2 are selected to distribute at least one first data packet group, FE1, FE2, and FE3 forward one or more first data packet groups sent by LC1 to LC2. Schematically, if FE1 receives a first data packet group sent by LC1, FE1 forwards the first data packet group to LC2, and if FE1 receives two first data packet groups sent by LC1, FE1 forwards the two first data packet groups to LC2. In this embodiment, the second device is connected to only one line card LC2, so at least one first data packet group is forwarded to LC2 through three switching devices. LC2 restores one or more first data packet groups received from FE1, FE2 and FE3 to obtain multiple first data packets, stores the first data packets in the buffer of each port, and forwards the first data packets to VM2.

[0072] refer to Figure 7 , Figure 7 The network diagram provided in the embodiment of the present application Figure 2 , and networking diagram Figure 1The difference is that an external control device is added. The control device is a control line card. The control device collects the topological connection relationship of the entire system, and collects the bidirectional traffic of each FE and LC through message statistics, and forms an overall load connection diagram. When WMA sends a message to VMB, the LC1 line card can use the control device to obtain the load situation from LC1 to each FE node and from each FE node to LC3 node, and then decide on the route selection.

[0073] It should be noted that Figure 5 , Figure 6 and Figure 7 The networking connection method shown in is only an example. When the present application is actually applied to a specific networking connection method, other networking connection methods can be used for networking. For example, in order to improve transmission efficiency or facilitate backup, a virtual machine is connected to multiple line cards.

[0074] In some optional implementations, after receiving the plurality of first data packets, the method further includes:

[0075] storing the plurality of first data packets;

[0076] Sending a first space request message to a switching network board, wherein the switching network board includes the at least one first switching device;

[0077] receiving a first space request response message sent by the switching network board, where the first space request response message is used to indicate whether the second device has a cache space for processing the first data packet;

[0078] The step of assembling the plurality of first data packets to obtain at least one first data packet group includes:

[0079] If the first space request response message indicates that the second device has cache space for processing the first data packet, the multiple first data packets are assembled to obtain at least one first data packet group.

[0080] Due to the easy scalability of switching equipment, each device involved in data forwarding can be elastically expanded, and interactive devices suitable for different business scenarios can be added to the switching network board to meet different business scenarios. For example, switching devices suitable for real-time and high-speed business scenarios can be added to the switching network board to meet real-time and high-speed business scenarios.

[0081] The line card receives data packets from the network and classifies them into the VOQ of the line card for storage. Before sending the data packets, a space request control message is sent to determine whether the second device has enough buffer space to process the messages.

[0082] If the first space request response message is not received or the second device is temporarily unable to process the message, the message will be temporarily stored in the storage of the first device, where the line card has on-chip and off-chip caches, which can cache data for a period of time. The message will only be sent when the second device confirms that it can be received, avoiding the problem of packet loss caused by direct forwarding to the second device.

[0083] In some optional implementations, the sending the first space request message to the switching network board includes:

[0084] selecting a link for sending the first space request message based on the load condition connection diagram;

[0085] According to the sending link, a first space request message is sent to the switching network board.

[0086] In networking, a line card can be used as both an inbound line card and an outbound line card.

[0087] In some optional implementations, the networking method further includes

[0088] receiving a second data packet group sent by a second switching device; the second data packet group includes one or more second data packets, and the second data packet is a data packet sent by the second device to the first device;

[0089] Restoring the received second data packet group to obtain the one or more second data packets;

[0090] The one or more second data packets are sent to the first device.

[0091] In actual application, the line card restores the second data packet group to one or more second data packets, stores the second data packets in the buffer of each port, and then forwards the second data packets to the first device.

[0092] In some optional implementations, the networking method further includes

[0093] receiving a second space request message sent by the second switching device, where the second space request message is used to determine whether the buffer space of the first device is greater than or equal to the buffer space required for processing the second data packet;

[0094] Based on the second space request message, obtaining a cache space of the first device;

[0095] When the cache space of the first device is greater than or equal to the cache space required for processing the second data packet, a second space request response message is sent to the second switching device, where the second space request response message is used to indicate that the first device has cache space for processing the second data packet.

[0096] Exemplary, reference Figure 8 , Figure 8 A schematic diagram of the message format header of the space request message and the space request response message provided in the embodiment of the present application, such as Figure 8 As shown, the DMAC position is the MAC of the outgoing line card, the SMAC position is the MAC of the incoming line card, the TYPE position is the message type, the DIP position is the IP of the outgoing line card, the SIP position is the IP of the incoming line card, the Command Type is the message type, exemplarily, 00 represents request, 01 represents response, and it can be set according to the actual situation in actual application, and this application does not limit this, the Space position is the requested space, the Free space or not position is the result of the response, exemplarily, 00 represents initialization, 01 represents no space, and 10 represents space. It can be set according to the actual situation in actual application, and this application does not limit this, and the Payload position is the load.

[0097] refer to Fig. 9 , Fig. 9 Schematic diagram of the implementation process of the networking method provided in the embodiment of the present application Figure 2 In this embodiment, the networking method is applied to a switching device, and the method includes the following steps:

[0098] Step 901: Receive a first data packet group sent by a first line card, where the first data packet group includes one or more first data packets, and the first data packet is one of multiple first data packets sent by a first device to a second device.

[0099] In actual application, the switching device may be an independent box switch or router device, or other device, and this application does not limit this.

[0100] Step 902: forward the first data packet group to a second line card; wherein the first line card is a line card to which the first device is connected, and the second line card is a line card to which the second device is connected.

[0101] In some optional implementations, the data packet carries at least one of the following information: first information, second information, and third information; wherein,

[0102] The first information represents the number of the data packet group to which the data packet belongs;

[0103] The second information indicates whether the data packet is the starting data packet of the data packet group to which the data packet belongs;

[0104] The third information indicates whether the data packet is the end data packet of the data packet group to which it belongs.

[0105] In some optional embodiments, the method further comprises:

[0107] Receive a first space request response message sent by the second line card, and send the first space request response message to the first line card; wherein the first space request response message is used to indicate whether the second device has a cache space for processing the first data packet.

[0108] The networking method provided in the embodiment of the present application adopts a high-performance network architecture solution with packet switching technology as a whole. The line card device and the switching network device adopt the control request message and space confirmation message format in the embodiment of the present application to confirm the space information. Multiple messages are combined into a group in the line card device. Packet group information is stored in the message and participates in the sorting of the group message. A control card or control device is added to form an overall load connection topology diagram, and a full-path load balancing solution is adopted.

[0109] The networking method provided in the embodiment of the present application adopts packet switching technology, with a large number of optional chips and product forms, and can be realized by simple transformation of existing equipment. At the same time, it can flexibly support larger-scale networks. There is no need to support cell switching. The adopted packet switching method is simple and convenient, and the network cost is lower. At the same time, since the message remains unchanged, the problem that the cell exchange is fragmented into small pieces and difficult to track and locate can be solved; the system packet loss can be reduced through simple message interaction; the packet group information can ensure the correct order of the message; the full-path load balancing solution makes the flow load more balanced on different paths when forwarding through multiple paths.
