[0058] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are used to explain the present application and are not used to limit the present application.

[0059] With the widespread application of cloud computing, more and more applications are deployed on cloud networks, showing two trends: 1) The networking of cloud networks is becoming more and more complex. In addition to the most basic virtual machine intercommunication across hosts through the Overlay network, there is also intercommunication across Subnets, across VPCs, across Available Zones, across Regions, virtual machines and bare metal interconnection (non-intelligent network cards, based on hardware switch encapsulation vxlan network virtualization), on-cloud networks and off-cloud networks through dedicated lines, virtual machines accessing the public network through SNAT, external requests accessing virtual machines through DNAT, four-layer load balancing, seven-layer load balancing, and virtual machines accessing public services in the management area, etc. The forwarding paths for different target addresses are different; 2) As more and more virtual machines are placed on cloud networks, the forwarding routing table is also getting larger.

[0060] The cloud network of some cloud platforms is implemented through SDN of hardware switches. However, hardware SDN is more friendly to simple forwarding scenarios of communication between virtual machines, but it cannot adapt to the many complex scenarios mentioned above. In addition, due to the current memory status of the hardware, it cannot carry the storage of such large-scale forwarding routing tables.

[0061] Another part of the cloud platform's cloud network is implemented through software SDN (Software Defined Network). Software SDN is more flexible and can handle more complex scenarios. The forwarding routing table is stored in memory and can carry a relatively large amount of storage. The mainstream software SDN network in the industry uses Openvswitch or similar Openvswtich principles to implement the data plane, or puts similar forwarding logic on the smart network card to implement it. It mainly stores the forwarding routing table through the five-tuple (source address, source port, destination address, destination port, protocol) flow table. The control plane uses Openflow or similar Openflow principles to implement the routing table from control to forwarding logic, or it is issued through self-developed protocols. However, this model has certain problems. For example, the aforementioned complex forwarding scenarios are all implemented using a unified five-tuple, so the control plane cannot distinguish these scenarios, nor can it efficiently save, compress, retrieve and eliminate routing tables for different scenarios. For another example, the volume of routing tables is very large, which poses great challenges to the latency and volume of the transmission. Therefore, the efficiency of data forwarding based on routing tables is extremely low.

[0062] To this end, the present application provides a data forwarding method. During the whole process, the routing update operation of the cloud network networking is responded to, the newly added cloud network segment information is obtained, and the target shared memory area matching the cloud network segment information is detected from the preset memory resource pool. Based on the cloud network segment information, the routing forwarding information in the target shared memory area is updated, wherein the routing forwarding information is stored in different shared memory areas of the preset memory resource pool, which solves the problem that the routing forwarding information is too large and consumes a large amount of host memory. Moreover, by dividing different shared memory areas based on the target address, it also solves the problem that the routing forwarding table is managed uniformly with a five-tuple and cannot be quickly queried due to different scenarios; further, through the target network control protocol, it can be ensured that the update of the target shared memory area will be updated to the target network forwarding node in real time, which solves the problem that a large amount of routing forwarding information can be sent down in real time, and improves the efficiency of routing information processing. Furthermore, it can achieve efficient control of the target network forwarding node to perform the forwarding operation of the network packet to be forwarded.

[0063] The data forwarding method provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown. Among them, the terminal 102 communicates with the server 104 through the network. The data storage system can store the data that the server 104 needs to process. The data storage system can be integrated on the server 104, or it can be placed on the cloud or other network servers. A management and control node 106 is deployed on the server 104, and a shared memory resource pool can be established in the server 104 where the management and control node is located.

[0064] The user issues a routing update request for the cloud network networking in the cloud network networking operation interface of the terminal 102, for example, to create other networks with which the cloud network communicates. The terminal 102 sends the routing update request for the cloud network networking to the server 104, and the management and control node 106 in the server 104 receives the request, responds to the routing update operation for the cloud network networking, and obtains the newly added cloud network segment information; detects the target shared memory area that matches the cloud network segment information from the preset memory resource pool, and updates the routing forwarding information in the target shared memory area based on the cloud network segment information; detects the target network forwarding node corresponding to the target shared memory area, and when the target network forwarding node receives the network packet to be forwarded, controls the target network forwarding node to read the updated routing forwarding information in the target shared memory area through the target network control protocol; wherein the target network control protocol is used to load the target shared memory area to the target network forwarding node; based on the updated routing forwarding information, controls the target network forwarding node to perform the forwarding operation of the network packet to be forwarded.

[0065] The terminal 102 may be, but is not limited to, various personal computers, laptops, smart phones, tablet computers, IoT devices, and portable wearable devices. IoT devices may be smart speakers, smart TVs, smart air conditioners, smart vehicle-mounted devices, projection devices, etc. Portable wearable devices may be smart watches, smart bracelets, head-mounted devices, etc. Head-mounted devices may be virtual reality (VR) devices, augmented reality (AR) devices, smart glasses, etc.

[0066] In an exemplary embodiment, Figure 2 As shown, a data forwarding method is provided, which is applied to Figure 1 The server 104 in FIG. 1 is used as an example for explanation. Among them:

[0067] S200, responding to the routing update operation for the cloud network networking, and obtaining the newly added cloud network segment information.

[0068] Among them, a cloud network is a computer network that includes at least some cloud network links. Networking technology refers to the technology of connecting multiple devices or systems to form a network in some way for data transmission and communication. When the cloud network is redefined, the routing information corresponding to the cloud network will also be updated. For example, if there are virtual machines in the original cloud network, when a new virtual machine is added to the original cloud network, the corresponding routing information will also be added. When a virtual machine is deleted from the original cloud network, the corresponding routing information will also be reduced. Routing refers to the network-wide process that determines the end-to-end path when a packet goes from source to destination.

[0069] Specifically, the network server on the cloud is divided into a management and control node and a data forwarding node. The user issues a routing update request for the cloud network in the cloud network operation interface of the terminal, for example, to create other networks for communication with the cloud network. The terminal sends the routing update request for the cloud network to the management and control node. The management and control node receives the request, responds to the routing update operation for the cloud network, obtains the routing update information, and extracts the target address from the routing update information. Alternatively, when the user performs a routing update operation for the cloud network through the API (Application Programming Interface), the management and control node responds to the routing update operation for the cloud network and obtains the newly added cloud network segment information.

[0070] For example, the original cloud network includes virtual machine a and virtual machine b, and its routing information is the routing mapping relationship information between virtual machine a and virtual machine b. When the user requests to create a new virtual machine c in the cloud network, the newly added cloud network segment information can be the routing mapping relationship information between virtual machine c and virtual machine b, as well as the routing mapping relationship information between virtual machine c and virtual machine a.

[0071] S400, detecting a target shared memory area that matches the cloud network segment information from a preset memory resource pool, and updating routing forwarding information in the target shared memory area based on the cloud network segment information.

[0072] The memory resource pool is a shared resource pool that can reach the TB (Terabyte) level and store massive routing and forwarding information. The routing and forwarding information can be represented in the form of a table, such as a routing forwarding table.

[0073] Specifically, a memory resource pool is established on the management and control node, and a shared memory area is allocated in the shared memory pool for routing forwarding information with different target addresses. That is, the routing forwarding information is stored in the shared memory area, the target address of the routing forwarding information in each shared memory area is the same, and the target addresses of the routing forwarding information in different shared memory areas are different.

[0074] Therefore, the corresponding target address can be extracted from the cloud network segment information, and the target shared memory area matching the target address can be detected from multiple shared memory areas in the memory resource pool. Then, the original routing forwarding information in the target shared memory area can be updated through the newly added cloud network segment information.

[0075] S600, detecting a target network forwarding node corresponding to the target shared memory area, and when the target network forwarding node receives a network packet to be forwarded, controlling the target network forwarding node to read updated routing forwarding information in the target shared memory area through a target network control protocol.

[0076] Among them, a target network control protocol is established between the control node and the network forwarding node, and the target network control protocol is used to load the target shared memory area to the target network forwarding node.

[0077] Specifically, each shared memory area corresponds to a network forwarding node. Each network forwarding node does not load all shared memory areas, but loads the shared memory area corresponding to the routing forwarding information that the virtual machine corresponding to the network forwarding node may access. In other words, each network forwarding node places the shared memory area where the routing forwarding information corresponding to the target address that it may go to on its own machine through the target network control protocol.

[0078] Among them, the target network control protocol is generally the CXL (Compute Express Link, high-speed connection protocol) 3.0 protocol. Among them, CXL 3.0 technology is a new open interconnection standard, based on the high-speed, low-latency CPU (Central Processing Unit) to device interconnection technology of the PCIe (peripheral component interconnect express, high-speed serial computer expansion bus standard) physical layer. Based on CXL 3.0, fine memory allocation (aggregation) and sharing can be achieved between multiple hosts to realize a shared memory pool. Applying this technology to the storage and distribution of routing tables can solve both the storage problem of routing tables and the problem of sending routing tables. CXL clusters can reach thousands of nodes and can cope with larger-scale cloud platforms.

[0079] Therefore, the target network forwarding node corresponding to the target shared memory area can be screened from multiple network forwarding nodes. When the target network forwarding node receives the network packet to be forwarded, the target shared memory area is loaded to the target network forwarding node due to the target network control protocol. At this time, the target network forwarding node can read the updated routing forwarding information in the target shared memory area in real time without the need for an additional delivery process, which is more efficient.

[0080] S800, based on the updated routing forwarding information, control the target network forwarding node to perform a forwarding operation of the network packet to be forwarded.

[0081] Specifically, when the target forwarding node obtains the updated routing forwarding information, it can control the target network forwarding node to perform the forwarding operation of the network packet to be forwarded, that is, the target network forwarding node queries the target forwarding address corresponding to the network packet to be forwarded from the updated routing forwarding information based on the updated routing forwarding information, and then forwards the received network packet to be forwarded to the target forwarding address.

[0082] In the above data forwarding method, in response to the routing update operation of the cloud network networking, the newly added cloud network segment information is obtained, and the target shared memory area matching the newly added cloud network segment information is detected from the preset memory resource pool, and the routing forwarding information in the target shared memory area is updated based on the cloud network segment information, wherein the routing forwarding information is stored in different shared memory areas of the preset memory resource pool, which solves the problem that the routing forwarding information is too large and consumes a large amount of host memory, and by dividing different shared memory areas based on the target address, it also solves the problem that the routing forwarding table is managed uniformly with a five-tuple and cannot be quickly queried due to different scenarios; further, through the target network control protocol, it can be ensured that the update of the target shared memory area will be updated to the target network forwarding node in real time, which solves the problem that a large amount of routing forwarding information can be sent down in real time, and improves the efficiency of routing information processing, and further, it can realize efficient control of the target network forwarding node to perform the forwarding operation of the network packet to be forwarded.

[0083] In an exemplary embodiment, detecting a target shared memory area matching cloud network segment information from a preset memory resource pool includes:

[0084] The routing type information matching the cloud network segment information is detected, and a target shared memory area matching the routing type information is detected from a preset memory resource pool.

[0085] Specifically, the shared memory area is used to store routing forwarding information, but the storage format of the routing forwarding information in the present application is not to use the existing five-tuple mode, but to store different types of routing forwarding information according to different target addresses. That is to say, the same type of routing forwarding information exists in each shared memory area, and different types of routing forwarding information exist in different shared memory areas, wherein the same type of routing forwarding information means that the target addresses of the routing forwarding information are consistent, and different types of routing forwarding information means that the target addresses of the routing forwarding information are inconsistent.

[0086] Therefore, the corresponding target address is extracted from the cloud network segment information, and the routing type information matching the target address is detected, and then the target shared memory area matching the routing type information is detected from multiple shared memory areas in the preset memory resource pool.

[0087] In this embodiment, based on the target address in the routing update information, routing type information matching the target address can be detected, and then based on the routing type information, the target shared memory area can be accurately determined to accurately store the routing update information in the target shared memory area.

[0088] In an exemplary embodiment, based on the updated routing forwarding information, controlling the target network forwarding node to perform a forwarding operation of the network packet to be forwarded includes:

[0089] The target routing address corresponding to the network packet to be forwarded is obtained from the updated routing forwarding information, and based on the target routing address, the target network forwarding node is controlled to perform a forwarding operation on the network packet to be forwarded.

[0090] Specifically, when the routing forwarding information in the target shared memory area corresponding to the target network forwarding node changes, the target network forwarding node can read the updated routing forwarding information in the target shared memory area in real time. Furthermore, when the target network forwarding node receives a network packet to be forwarded, it can obtain the target routing address corresponding to the network packet to be forwarded from the updated routing forwarding information, and based on the target routing address, control the target network forwarding node to perform the forwarding operation of the network packet to be forwarded, so as to accurately send the network packet to be forwarded to the corresponding target routing address.

[0091] In this embodiment, through the target network control protocol, the target network forwarding network can read the updated routing forwarding information in the target shared memory area, and query the target routing address corresponding to the network packet to be forwarded from the updated routing forwarding information, thereby accurately implementing the forwarding operation of the network packet to be forwarded.

[0092] In an exemplary embodiment, the routing type information includes a cloud network routing type, a bare metal cloud network routing type, a dedicated line routing type, and a network service routing type; and obtaining a target routing address corresponding to a network packet to be forwarded from the updated routing forwarding information includes:

[0093] In the case where the routing type information includes a cloud network routing type, obtaining first virtual machine routing information corresponding to the network packet to be forwarded, and searching for first host machine routing information corresponding to the first virtual machine routing information from the updated routing forwarding information;

[0094] When the routing type information includes a bare metal cloud network routing type, obtaining access switch routing information corresponding to the network packet to be forwarded, and searching for bare metal server routing information corresponding to the access switch routing information from the updated routing forwarding information;

[0095] In the case where the routing type information includes a dedicated line routing type, obtaining the second virtual machine routing information corresponding to the network packet to be forwarded, and searching the network segment routing information in the off-cloud network corresponding to the second virtual machine routing information from the updated routing forwarding information, wherein the off-cloud network is connected to the cloud network through a dedicated line network;

[0096] In the case where the routing type information includes the network service routing type, the virtual routing information corresponding to the network packet to be forwarded is obtained, and the network server routing information corresponding to the virtual routing information is searched from the updated routing forwarding information.

[0097] The routing type information includes cloud network routing type, bare metal cloud network routing type, dedicated line routing type and network service routing type. Cloud network routing type includes same cloud network routing type and cross-cloud network routing type, and network service routing type includes public network service routing type and custom network service routing type.

[0098] Specifically, according to the route type information, the target route mapping relationship corresponding to the network packet to be forwarded is obtained from the updated route forwarding information, including the following situations:

[0099] The first one is for cloud network routing type:

[0100] When the cloud network routing type is the same cloud network routing type, there may be several virtual machines in the cloud network. The updated routing forwarding information includes the target routing mapping relationship information between the first virtual machine routing information corresponding to the cloud network and the first host machine routing information corresponding to the first virtual machine routing information. Therefore, the first virtual machine routing information corresponding to the network packet to be forwarded can be obtained, and based on the first virtual machine routing information, the first host machine routing information corresponding to the first virtual machine routing information is searched from the updated routing forwarding information.

[0101] In the case where the cloud network routing type is a cross-cloud network routing type, the updated routing forwarding information includes the target routing mapping relationship information between the first virtual machine routing information and the first host machine routing information corresponding to all cloud networks. For example, when the routing forwarding information is a VPC (Virtual Private Cloud) routing forwarding table, different VPC routing forwarding tables have VPCIDs, and VPCIDs are used as keys to identify different VPC routing forwarding tables. The VPC routing forwarding table stores the mapping relationship between the MAC (Media Access Control Address, LAN address) addresses of all virtual machines corresponding to the cloud network VPC and the IP address of the host machine where the IP (Internet Protocol Address, Internet Protocol address) address of the virtual machine is located. Among them, the MAC address, also known as the physical address or hardware address, is a unique identifier assigned to the network device when it is manufactured, usually embedded in the network interface card. The IP address is the logical address of the device in the network, which is assigned by the network service provider and is used to locate the device in the network. The virtual machine refers to multiple "virtual servers" running on a physical server. On the surface, these virtual machines are independent servers, but in fact, they share the CPU, memory, hardware, network card and other resources of the physical server. Therefore, the first virtual machine routing information corresponding to the network packet to be forwarded can be obtained, and based on the first virtual machine routing information, the first host machine routing information corresponding to the first virtual machine routing information can be searched from the updated routing forwarding information.

[0102] For example, for access to the same VPC, that is, the same cloud network routing type, the target VPCID and the target address are both within this VPC. You only need to read the VPC routing table, find the mapping relationship, put the corresponding virtual machine's MAC address and IP address in the inner layer of the Overlay network packet, and put the virtual machine's host machine's IP address in the outer layer of the Overlay network packet, and the network packet to be forwarded can be delivered.

[0103] For cross-VPC access, that is, cross-cloud network routing type, a peer connection needs to be established between the two VPCs. If the target VPCID and target address are in the peer VPC, it is necessary to read the peer VPC routing forwarding table, find the mapping relationship, and then perform Overlay encapsulation similar to access to the same VPC, so that the network packet to be forwarded can be delivered.

[0104] The second type is for bare metal cloud network routing types:

[0105] The bare metal cloud network routing type is the type of communication established between the bare metal server and the cloud network. The updated routing forwarding information includes the target routing mapping relationship between the access switch routing information corresponding to the cloud network, the virtual extended LAN routing information, and the bare metal server routing information. Therefore, the access switch routing information corresponding to the network packet to be forwarded can be obtained, and based on the access switch routing information, the bare metal server routing information corresponding to the access switch routing information can be found from the updated routing forwarding information.

[0106] For example, you can also create a VPC for a bare metal server, but the VPC is implemented on a physical switch through vxlan. On the RR (Route Reflector) on the bare metal networking side, you can obtain the mapping relationship between the access switch routing information, VTEP (Visual eXtensible Local Area Network Tunnel Endpoint) routing information, and the bare metal server routing information, and write the mapping relationship into the bare metal VPC routing table. The key of the bare metal VPC routing table is the VPCID of the bare metal VPC. If a virtual machine in the cloud network needs to access the bare metal server, after looking up the mapping relationship in this table, the MAC and IP of the virtual machine and the MAC and IP of the bare metal server are placed in the inner layer of the Overlay network packet, and the host IP and the IP address of the VTEP are placed in the outer layer, and the network packet to be forwarded can be delivered.

[0107] The third type is for dedicated line routing types:

[0108] The dedicated line route type refers to communicating with the cloud network in the cloud network through a dedicated line. At this time, the updated route forwarding information includes the target route mapping relationship between the second virtual machine routing information corresponding to the cloud network, the second host routing information, and the network segment routing information in the cloud network. Therefore, the second virtual machine routing information corresponding to the network packet to be forwarded can be obtained, and based on the second virtual machine routing information, the second host routing information corresponding to the second virtual machine routing information is searched from the updated route forwarding information, and then the network segment routing information in the cloud network corresponding to the second host routing information is searched.

[0109] For example, if there is a network segment under the cloud that needs to communicate with the VPC on the cloud, it is often sent to the dedicated gateway after being encapsulated as vxlan through a dedicated switch. The dedicated gateway can find the host where the virtual machine is located through the VPC routing table, encapsulate vxlan and forward it. If the virtual machine on the cloud wants to access the network segment under the cloud, it directly forwards the network packet to be forwarded to the dedicated gateway, and then sends it to the dedicated switch and decapsulates it.

[0110] The fourth type is for network service routing type:

[0111] The network service routing type is the communication between the virtual machines in the cloud network and other network servers. The updated routing forwarding information includes the target routing mapping relationship between the virtual routing information corresponding to the cloud network and the server routing information of the network server. Therefore, the virtual routing information corresponding to the network packet to be forwarded can be obtained, and the network server routing information corresponding to the virtual routing information can be found from the updated routing forwarding information.

[0112] For example, when the network service routing type is the public network service routing type, if you want to access public management services such as NTP, yum and OpenAPI on the cloud, a virtual address VPCip will be assigned to these services by default in the VPC. When accessing these virtual addresses, the underlay address of the management network (corresponding to the VPC ip) of these services is obtained from this routing forwarding table, and the network packet to be forwarded is sent after decapsulation.

[0113] When the network service routing type is a custom network service routing type, it is similar to the public service routing table, but it is not assigned by default, but requires manual binding by the user, such as accessing object storage and databases in the underlay network. When the user manually binds, a mapping relationship between the VPC IP and the underlay IP will be created in this routing table. When accessing these VPC IPs, the management network underlay addresses of these services are obtained from this routing table, and the network packets to be forwarded are sent after decapsulation.

[0114] In this embodiment, multiple shared memory areas are set to store different types of routing forwarding information respectively, so that in the forwarding process based on routing forwarding information, each forwarding node will not obtain all routing forwarding information, but will obtain the shared memory corresponding to the routing forwarding information that the local machine may access. Enjoy Memory area. For example, when the routing information is represented in a table, the VPC routing table belonging to this VPC will be obtained; if this VPC is peered with another VPC, the VPC routing table of the peer VPC will also be obtained; if this VPC is connected to the cloud network through a dedicated line, the dedicated line routing table will be obtained; all public service routing tables will be obtained; if this VPC needs to access the underlay service and has made a mapping, the underlay service routing table will be obtained. Once the forwarding node creates these peers, Enjoy After the memory area, when the control node accepts user requests and updates these routing tables, the network forwarding nodes will be updated synchronously according to the CXL protocol, realizing the real-time delivery of routing tables.

[0115] In an exemplary embodiment, before controlling the target network forwarding node to read the updated routing forwarding information in the target shared memory area through the target network control protocol, the method further includes:

[0116] A communication connection is established between the target network forwarding node and the control node where the target shared memory area is located, and the target shared memory area is loaded to the target network forwarding node by using the established communication connection through the target network control protocol.

[0117] Specifically, a communication connection is established between the control node and multiple network forwarding nodes so that the shared memory area can be loaded into the network forwarding node. Furthermore, the communication connection established between the control node and multiple network forwarding nodes does not mean that the network forwarding node can obtain all the routing forwarding information in the memory resource pool in the control node. Instead, the shared memory area in the control node is loaded into the network forwarding node corresponding to the shared memory area through the communication connection. For example, the target network forwarding node is the network forwarding node corresponding to the target shared memory area. Therefore, the target shared memory area can be loaded into the target network forwarding node through the target network control protocol using the communication connection established between the target network forwarding node and the control node, so as to realize the real-time acquisition of the updated routing forwarding information in the target shared memory area by the target network forwarding node.

[0118] In this embodiment, by establishing a communication connection between the target network forwarding node and the management and control node where the target shared memory area is located, the target shared memory area can be accurately loaded into the target network forwarding node through the communication connection, so that the subsequent target network forwarding node can obtain the updated routing forwarding information in the target shared memory area in real time without the need for an additional delivery process, thereby improving the efficiency of obtaining routing information.

[0119] In an exemplary embodiment, Figure 3 As shown, before S200, it also includes:

[0120] S120: In response to the creation operation for the cloud network, a cloud network identifier is allocated to the created cloud network.

[0121] S140, based on the cloud network identifier, generating routing information matching the cloud network identifier in a preset memory resource pool.

[0122] S160, responding to the networking creation operation of the cloud network, obtaining the networking information of the cloud network, and based on the networking information, updating the routing information in the preset memory resource pool to obtain routing forwarding information.

[0123] Specifically, before responding to the routing update operation for the cloud network networking, it is also necessary to create the cloud network and the networking corresponding to the cloud network. The management and control node responds to the creation operation for the cloud network, allocates a cloud network identifier to the created cloud network, and at the same time, based on the cloud network identifier, creates a routing information with the cloud network identifier as the key in the memory resource pool corresponding to the management and control node, such as a routing forwarding table.

[0124] After the cloud network is created, the device networking in the cloud network is created, the management and control node responds to the networking creation operation for the cloud network, obtains the networking information in the cloud network, and based on the networking information, updates the routing information corresponding to the cloud network in the memory resource pool to obtain the routing forwarding information.

[0125] Taking the cloud network as VPC as an example, when a user request is accepted to create a VPC, a VPCID will be assigned. In addition to being saved in the database, a VPC routing table with VPCID as the key is also created in the CXL shared memory resource pool. When a user request is accepted to create a virtual machine in this VPC, the virtual machine is assigned to a host machine. The networking information obtained at this time can be the mapping relationship between the newly created virtual machine MAC address, virtual machine IP and host machine IP. The mapping relationship is added to the VPC routing table, and the updated routing information is then saved in the VPC routing table.

[0126] Furthermore, when responding to a cloud network creation operation, the cloud network identifier can be used to verify whether the network created is the corresponding cloud network. When responding to a cloud network routing update operation, the cloud network identifier can also be used to verify whether the network update is the corresponding cloud network.

[0127] That is to say, the first network identifier in the network creation request of the cloud network is obtained, and based on the first network identifier, the routing information corresponding to the first network identifier is queried in the preset memory resource pool, so as to update the routing information corresponding to the first network identifier in the preset memory resource pool based on the device networking information, and obtain the routing forwarding information.

[0128] When responding to the routing update operation of the cloud network networking, the second routing identifier in the routing update request of the cloud network networking can also be obtained. Based on the second network identifier, the routing forwarding information corresponding to the second network identifier is queried in the preset memory resource pool, and the routing forwarding information corresponding to the second network identifier is updated in the preset memory resource pool based on the routing update information to obtain the updated routing forwarding information.

[0129] In this embodiment, before updating the routes of the cloud network networking, it is necessary to first create a cloud network and a device networking in the cloud network, and then update the routes of the cloud network networking. By assigning a cloud network identifier to the created cloud network, the routing information corresponding to multiple cloud networks can be distinguished, so as to accurately update the routing forwarding information of the cloud network networking corresponding to the cloud network identifier.

[0130] In an exemplary embodiment, taking the routing forwarding information as a routing forwarding table as an example, the essence of this application is to optimize the data forwarding method of the cloud network based on the CXL 3.0 shared memory resource pool. Specifically:

[0131] like Figure 4 As shown in the figure, the cloud network is divided into control nodes and network forwarding nodes. A CXL network is built between the control nodes and the network forwarding nodes, and a memory resource pool is built on the control node based on the memory pool orchestrator and the CXL binding controller. In the memory resource pool, the storage format of the routing table is redesigned. The five-tuple mode is no longer used. Instead, different routing tables are stored according to different target addresses. Shared memory areas are allocated to different routing tables in the memory resource pool. Different routing tables include but are not limited to: VPC routing table 1, VPC routing table N, bare metal VPC routing table 1, bare metal VPC routing table N, dedicated line routing table N, public service routing table N, custom service routing table N, etc.

[0132] When the user defines the cloud network through the API interface, the management and control node receives the request through the message queue and obtains the routing update information in the request. On the one hand, the routing update information is saved in the database, and based on the target address corresponding to the routing update information, on the other hand, the target shared memory area matching the target address is detected to update the corresponding routing forwarding table in the target shared memory area based on the routing update information and save it in the target shared memory area.

[0133] The network forwarding node corresponding to each virtual machine places the shared memory area where the forwarding table corresponding to the target address of its possible destination is located on the local machine through the CXL protocol. When the control node updates the shared memory area, all network forwarding nodes can obtain the changes in the shared memory area in real time through the CXL network, without the need for an additional delivery process. When forwarding the network packets of the virtual machine, the network forwarding node can directly read the data in the shared memory area. Among them, the CXL shared memory pool can reach the TB level and can store a large number of routing forwarding tables. The CXL cluster can reach thousands of nodes and can cope with larger-scale cloud platforms.

[0134] Furthermore, each forwarding node will not obtain all routing forwarding tables, but will obtain the shared memory area corresponding to the routing forwarding tables that the local machine may access. For example, the VPC routing table belonging to this VPC will be obtained; if this VPC and another VPC have a peer connection, the VPC routing table of the peer VPC will also be obtained; if this VPC is connected to the cloud network through a dedicated line, the dedicated line routing table will be obtained; all public service routing tables will be obtained; if this VPC needs to access the underlay service and has made a mapping, the underlay service routing table will be obtained. Once the forwarding node creates these memory regions, when the control accepts user requests and updates these routing tables, the forwarding node will be updated synchronously according to the CXL protocol to achieve real-time VXLAN encapsulation and delivery of network packets.

[0135] For example, in Figure 4 In the example, each computing node has a network forwarding node. Network forwarding node 1 can obtain VPC routing table 1, VPC routing table N, and bare metal VPC routing table N. Network forwarding node 2 can obtain VPC routing table 1. Network forwarding node 3 can obtain VPC routing table N1. Based on the routing table obtained in the computing node, network packets can also be encapsulated in VXLAN and forwarded to other computing nodes in real time. For example, if forwarding is based on bare metal VPC routing table N, the network packet can be forwarded to the physical switch of the bare metal server to access the bare metal server node.

[0136] like Figure 5 As shown, the data forwarding process of this application is described through a fact case based on OpenStack.

[0137] Specifically, the network management module of OpenStack is Neutron. Neutron-Server can be deployed on an ordinary server as a network service. Neutron can have a network plug-in, which can connect to a remote network control module. On the server where the network control module is located, a shared memory resource pool can be established through the CXL network control protocol. The memory resource pool includes multiple shared memory areas, and the shared memory areas store routing tables, such as VPC routing table 1, VPC routing table N, bare metal VPC routing table 1, bare metal VPC routing table N, dedicated line routing table N, public service routing table N, custom service routing table N, etc.

[0138] When OpenStack Neutron receives a user request to create a VPC through a message queue, it assigns a VPCID. This data is not only stored in the Neutron-Server database, but also creates a VPC routing table with the VPCID as the key in the CXL shared resource pool.

[0139] When OpenStack Nova accepts a user request to create a virtual machine in this VPC, the virtual machine is assigned to a host machine, and the mapping relationship between the virtual machine MAC, virtual machine IP, and host IP is saved in the VPC routing forwarding table.

[0140] The host where this virtual machine is located needs to obtain the shared memory area that stores this VPC routing table through the CXL protocol and load it locally.

[0141] Whenever a new virtual machine is created in this VPC, Neutron control will update the VPC routing table in this shared memory area, and the host will update the VPC routing table in real time through the CXL protocol. Then, this virtual machine can access the new virtual machine through VXLAN encapsulation through the mapping relationship in the VPC routing table.

[0142] The data forwarding method of the present application can also improve the richness of the cloud network networking of the cloud platform, as well as the performance and real-time nature of the cloud network forwarding of the cloud platform. Therefore, in the future, it can be applied to: 1. Fields where the cloud platform has relatively high requirements for network forwarding; 2. Fields where the cloud platform has relatively complex cloud network networking; 3. Fields where the cloud platform has a relatively large amount of cloud network forwarding table data.
