[0050] In the related technologies known to the inventors, an Underlay network is a physical network responsible for transmitting data packets, composed of devices such as switches and routers, and driven by protocols such as Ethernet, routing protocols, and VLANs. All network components within an Underlay network must determine IP connections using routing protocols such as IGP. An Overlay network is a logical network that establishes connections on top of the physical infrastructure using network virtualization, achieving separation of the control plane and the forwarding plane.

[0051] Underlay networks use routing protocols for service scheduling and management, making it impossible to schedule computing resources like those in overlay networks. GRE (Generic Data Environment) is a protocol for traversing networks, encapsulating data packets from one network protocol within data packets from another for transmission between different networks. GRE consists of a header and a payload; the header stores information about the data packet, and the payload stores the data to be transmitted. GRE can be used to build Virtual Private Networks (VPNs) to improve network security. GRE uses IP as its transport layer protocol, encapsulating other network layer protocols on top of IP to enable communication between different network layers.

[0052] Existing computing power networks typically schedule computing resources based on traditional three-layer networks (Underlay), which is not suitable for overlay networks using the GRE protocol (GRE network). Furthermore, existing computing power networks usually employ a controller to orchestrate and schedule nodes; this controller cannot automatically synchronize and schedule information based on network information, making it unsuitable for GRE networks. Therefore, this disclosure proposes a technical solution for computing power processing based on the GRE protocol in overlay networks.

[0053] Figure 1 This is a flowchart illustrating an embodiment of the computing power provision method according to the present disclosure, which is applied to a first tunnel endpoint device, such as... Figure 1 As shown:

[0054] Step 101: Send a GRE protocol computing power notification message to the second tunnel endpoint device; wherein, the GRE protocol computing power notification message carries computing power information.

[0055] In one embodiment, a tunnel endpoint device is deployed in a GRE network (a GRE network being an overlay network using the GRE protocol) to perform packet encapsulation and decapsulation. One or more tunnels can be established between the first tunnel endpoint device and the second tunnel endpoint device. The GRE protocol computing power notification message sent by the first tunnel endpoint device to the second tunnel endpoint device is a computing power notification message encapsulated using the GRE protocol and sent within the GRE tunnel. The GRE protocol can be IPv6 GRE, etc. The IPv6 GRE protocol can encapsulate different network layer protocols within the IPv6 protocol, enabling communication between different network layers. Encapsulating the computing power notification message using the IPv6 GRE protocol allows the encapsulated GRE protocol computing power notification message to be transmitted within the IPv6 network.

[0056] Computing power information includes information about computing resources, which include at least one of the following: Central Processing Unit (CPU) resources, Graphics Processing Unit (GPU) resources, Data Processing Unit (DPU) resources, and memory resources. The computing power information carried in the GRE protocol computing power notification message includes information about CPU resources, GPU resources, DPU resources, and memory resources. For example, CPU resource information includes information such as the CPU frequency.

[0057] Step 102: Provide computing power services based on the received computing power service request message sent by the second tunnel endpoint device.

[0058] In one embodiment, the first tunnel endpoint device uses various existing methods to provide computing power services to devices connected to the second tunnel endpoint device, enabling these devices to utilize resources such as servers connected to the first tunnel endpoint device. Upon receiving a computing power service request message from the second tunnel endpoint device, the first tunnel endpoint device determines the computing power services required by the second tunnel endpoint device based on the request message.

[0059] For example, a computing power service request might be a request to perform facial recognition on an image. The request message carries the image, a facial recognition request code, and the IP address of the device connected to the second tunnel endpoint device. Upon receiving the computing power service request, the first tunnel endpoint device sends the image to resources such as a server connected to it for facial analysis.

[0060] The first tunnel endpoint device returns the face recognition result to the second tunnel endpoint device based on computing power routing. The second tunnel endpoint device then returns the recognition result to the devices connected to it. The face recognition result includes the face recognition result and the IP address of the device connected to the second tunnel endpoint device. Computing power routing is the data forwarding route determined by the second tunnel endpoint device when selecting a path, taking into account computing power information, and then sends it to the first tunnel endpoint device.

[0061] The computing power provision method in the above embodiments transmits computing power information through GRE protocol messages, enabling tunnel endpoint devices to perform computing power scheduling based on the computing power information carried in the GRE protocol messages, thereby meeting the computing power scheduling requirements in the GRE network.

[0062] In one embodiment, the computing power information is the computing power information of a server connected to the first tunnel endpoint device. When the server starts up and connects to the first tunnel endpoint device, a GRE protocol computing power notification message is sent to the second tunnel endpoint device. For example, in a GRE tunnel between the first and second tunnel endpoint devices, the first tunnel endpoint device sends a GRE protocol computing power notification message to the second tunnel endpoint device.

[0063] GRE can be used as a Layer 3 tunneling protocol for VPNs, providing a transparent transmission channel for VPN data. The GRE protocol provides a mechanism for encapsulating packets for protocols such as IPv6, enabling packets to be transmitted across heterogeneous networks. The channel for heterogeneous packet transmission is called a tunnel. A tunnel is a virtual point-to-point connection. Encapsulated data packets can be transmitted within the tunnel, and packets are encapsulated and decapsulated at both ends of the tunnel.

[0064] The system can assign an interface number to the GRE tunnel and send information such as the source address, destination address, and interface number to the first tunnel endpoint device and the second tunnel endpoint device. The first tunnel endpoint device and the second tunnel endpoint device can use various existing methods to establish a GRE tunnel between the first tunnel endpoint device and the second tunnel endpoint device. The GRE tunnel can be an IPv6 GRE tunnel, etc.

[0065] In one embodiment, the first tunnel endpoint device receives a GRE protocol computing power service request message sent by the second tunnel endpoint device within the GRE tunnel. The computing power service request message can be various types of request messages. For example, it may include a GRE protocol computing power service request message, which is a computing power service request message encapsulated using the GRE protocol. The computing power service request message can be various IP messages, carrying information including computing power request information and the IP address of the device connected to the second tunnel endpoint device. The computing power request information may include facial recognition information, etc.

[0066] If the resources corresponding to the computing power information become unavailable or are migrated, the first tunnel endpoint device sends a GRE protocol computing power revocation notification message to the second tunnel endpoint device. Situations where the resources corresponding to the computing power information become unavailable or are migrated include server downtime or migration of the server providing the computing power service. The computing power revocation notification message carries information such as service termination information. The GRE protocol computing power notification message sent by the first tunnel endpoint device to the second tunnel endpoint device is a computing power revocation notification message encapsulated using the GRE protocol. For example, in a GRE tunnel, a GRE protocol computing power revocation notification message is sent to the second tunnel endpoint device.

[0067] In one embodiment, computing power information can be carried in the extended fields of the GRE header in the GRE protocol computing power notification message; and revocation notification information can be carried in the extended fields of the GRE header in the GRE protocol computing power revocation notification message.

[0068] Computing power information is transmitted through extended GRE protocol fields, including information on CPU resources, GPU resources, DPU resources, memory resources, etc. When selecting a route at the second tunnel endpoint device, the computing power information sent by the first tunnel endpoint device is used as one of the reference bases for determining the route (computing power routing).

[0069] The reserved fields in GRE packets are defined and extended to generate extended fields without changing the original packet structure. These extended fields are used for advertising computing power information. A GRE packet consists of a header and a payload, with the header including the GRE header itself. When the system receives data from a network layer protocol (such as IPv4 or IPv6) that requires encapsulation and routing, it adds a GRE header to the data, making it a GRE packet, and then encapsulates it within another protocol (such as IPv4 or IPv6). Forwarding this packet can then be entirely handled by the IP protocol.

[0070] The format of the GRE message header is as follows: Figure 2 As shown, C is the checksum verification bit, Reserved0 is a reserved field, Ver is the version field, Protocol Type is the message protocol before encapsulation, and Checksum is the checksum field for the GRE message header and its payload. Reserved1 is a reserved field, which has been redefined as an extended field for the announcement of computing power information.

[0071] For example, Reserved1 can define fields for CPU resources, GPU resources, DPU resources, and memory resources, each field consisting of 4 bits, used to carry information about CPU resources, GPU resources, DPU resources, and memory resources, respectively. Reserved1 can also be redefined as an extended field for announcing revocation notifications. For instance, the first 6 bits of Reserved1 can be used as a revocation notification field. If the revocation notification information carried through this field is "111111", then this message is identified as a GRE protocol computing power revocation notification message.

[0072] Figure 3 A schematic diagram illustrating the process of providing computing power services from the first tunnel endpoint device to the second tunnel endpoint device, as shown below. Figure 3 As shown:

[0073] Step 301: Establish a GRE tunnel between the first tunnel endpoint device and the second tunnel endpoint device.

[0074] The first and second tunnel endpoint devices can establish a GRE tunnel using various existing methods based on the GRE protocol. For example, the first and second tunnel endpoint devices can establish a GRE tunnel based on configuration information (system-assigned source address, destination address, and interface number, etc.) and the GRE protocol. The GRE tunnel can be an IPv6 GRE tunnel, etc.

[0075] Step 302: When the server is started (online) and connected to the first tunnel endpoint device, the server reports computing power information to the first tunnel endpoint.

[0076] Step 303: Based on the computing power information reported by the server, the first tunnel endpoint device generates a GRE protocol computing power notification message and sends it to the second tunnel endpoint device in the GRE tunnel. The GRE protocol computing power notification message carries the computing power information reported by the server.

[0077] Step 304: The client starts up (goes online) and connects to the second tunnel endpoint device. The client can be various user devices.

[0078] Step 305: When the client starts up (goes online) and connects to the second tunnel endpoint device, the second tunnel endpoint device determines the computing power route based on the computing power information. This computing power route includes the client IP address, as well as the address information of the target first tunnel endpoint device and the second tunnel endpoint device. The second tunnel endpoint device encapsulates this computing power route information using the GRE protocol and sends it to the first tunnel endpoint device.

[0079] Step 306: The second tunnel endpoint device sends a GRE computing power service request message to the first tunnel endpoint device (target first tunnel endpoint device) according to the computing power routing to request computing power services. Based on the received computing power service request message sent by the second tunnel endpoint device, the first tunnel endpoint device provides computing power services through the server and returns the computing power service results to the client through the second tunnel endpoint device according to the computing power routing.

[0080] Step 307: When the computing power service provided by the first tunnel endpoint device becomes unavailable or is migrated, the first tunnel endpoint device sends a GRE protocol computing power revocation notification message to the second tunnel endpoint device; upon receiving the GRE protocol computing power revocation notification message, the second tunnel endpoint device determines a new computing power route based on the computing power information.

[0081] Figure 4 This is a flowchart illustrating an embodiment of the computing power request method according to the present disclosure. The computing power request method is applied to a second tunnel endpoint device, such as... Figure 4 As shown:

[0082] Step 401: Receive a GRE protocol computing power notification message sent by at least one first tunnel endpoint device; wherein the GRE protocol computing power notification message carries computing power information. For example, receive a GRE protocol computing power notification message sent by the first tunnel endpoint device in the GRE tunnel between the first tunnel endpoint device and the second tunnel endpoint device.

[0083] Step 402: Determine the computing power route based on computing power information.

[0084] In one embodiment, the second tunnel endpoint device can establish GRE tunnels with multiple first tunnel endpoint devices and receive GRE protocol computing power notification messages sent by the multiple first tunnel endpoint devices. When performing routing, the second tunnel endpoint device can use computing power routing as a basis in addition to existing routing selection. When determining computing power routing, computing power information is used as a reference condition for determining computing power routing.

[0085] The computing power routing determination rules can be varied. They can be based on information about at least one of the following resources sent by multiple first tunnel endpoint devices: CPU resources, GPU resources, DPU resources, and memory resources. From among the multiple accessible first tunnel endpoint devices, a target first tunnel endpoint device can be selected, and a computing power route corresponding to the target first tunnel endpoint device can be generated. For example, the maximum CPU frequency can be determined from among the CPU frequencies sent by the multiple accessible first tunnel endpoint devices. The first tunnel endpoint device corresponding to this maximum CPU frequency can be used as the target first tunnel endpoint device, and a computing power route can be generated between the client and the target first tunnel endpoint device. The computing power route includes the client's IP address, as well as the addresses of the target first tunnel endpoint device and the second tunnel endpoint device, among other information.

[0086] Step 403: Send a GRE computing power service request message to the target first tunnel endpoint device according to the computing power route to request computing power service.

[0087] In one embodiment, the computing power service request includes a GRE protocol computing power service request message, etc. For example, in a GRE tunnel between a target first tunnel endpoint device and a second tunnel endpoint device, a GRE computing power service request message is sent to the target first tunnel endpoint device.

[0088] When the client starts up and connects to the second tunnel endpoint device, a computing power route is determined based on computing power information. A GRE protocol computing power revocation notification message is received from the target first tunnel endpoint device and / or other first tunnel endpoint devices within the GRE tunnel between the target first tunnel endpoint device and / or other first tunnel endpoint devices and the second tunnel endpoint device. Upon receiving the GRE protocol computing power revocation notification message from the target first tunnel endpoint device and / or other first tunnel endpoint devices, a new computing power route is determined based on the computing power information.

[0089] When selecting a path, the second tunnel endpoint device adds a metric for computing power routing. When accessing the same service, it prioritizes the path with higher computing power. For example, it can determine the size of at least one of the CPU, GPU, DPU, and memory resources carried in the GRE protocol information, and select a path based on the determination result to achieve GRE forwarding based on computing power resources.

[0090] like Figure 5 As shown, the second tunnel endpoint device 43 establishes GRE tunnels with the first tunnel endpoint devices 41 and 42, which provide service A, respectively. It receives GRE protocol computing power notification messages from the first tunnel endpoint devices 41 and 42, and obtains computing power information of the servers connected to the first tunnel endpoint devices 41 and 42 from these messages. This computing power information includes at least one of the following resource information: CPU resources, GPU resources, DPU resources, and memory resources. For example, when selecting a path for service A, the second tunnel endpoint device 43 can select a path based on CPU frequency, prioritizing the path with higher computing power. In other words, it selects the first tunnel endpoint device 42, which has a higher CPU frequency, as the target first tunnel endpoint device.

[0091] The computing power provision method and computing power request method disclosed herein transmit computing power information through GRE protocol messages, enabling tunnel endpoint devices to perform computing power scheduling based on the computing power information carried in the GRE protocol messages, thereby meeting the computing power scheduling requirements in the GRE network; by determining computing power routes based on computing power information in the GRE network, the rationalization of computing power scheduling is achieved, effectively saving network resources.

[0092] In one embodiment, such as Figure 6 As shown, this disclosure provides a first tunnel endpoint device 60, including a computing power notification module 61 and a service provision module 62. The computing power notification module 61 sends a Generic Routing Encapsulation (GRE) protocol computing power notification message to a second tunnel endpoint device. The GRE protocol computing power notification message carries computing power information. The service provision module 62 provides computing power services based on the received computing power service request message sent by the second tunnel endpoint device.

[0093] In one embodiment, the computing power information is the computing power information of the server connected to the first tunnel endpoint device. When the server starts up and connects to the first tunnel endpoint device, the computing power notification module 61 sends a GRE protocol computing power notification message to the second tunnel endpoint device. The computing power notification module 61 sends the GRE protocol computing power notification message to the second tunnel endpoint device within the GRE tunnel between the first and second tunnel endpoint devices.

[0094] In one embodiment, the computing power service request includes a GRE protocol computing power service request message; the service providing module 62 receives the GRE protocol computing power service request message sent by the second tunnel endpoint device in the GRE tunnel. If the resource corresponding to the computing power information becomes unavailable or is migrated, the service providing module 62 sends a GRE protocol computing power revocation notification message to the second tunnel endpoint device. The service providing module 62 can send the GRE protocol computing power revocation notification message to the second tunnel endpoint device within the GRE tunnel.

[0095] In one embodiment, such as Figure 7 As shown, the first tunnel endpoint device may include a memory 71, a processor 72, a communication interface 73, and a bus 74.

[0097] In one embodiment, such as Figure 8 As shown, this disclosure provides a second tunnel endpoint device 80, including a computing power receiving module 81, a target determination module 82, and a service request module 83. The computing power receiving module 81 receives GRE protocol computing power notification messages sent by at least one first tunnel endpoint device; wherein the GRE protocol computing power notification message carries information including computing power information. The target determination module 82 determines a computing power route based on the computing power information, and the service request module 83 sends a GRE computing power service request message to the target first tunnel endpoint device according to the computing power route to request computing power services.

[0098] In one embodiment, the computing power receiving module 81 receives a GRE protocol computing power notification message sent by the first tunnel endpoint device in the GRE tunnel between the first tunnel endpoint device and the second tunnel endpoint device. The computing power service request includes a GRE protocol computing power service request message, and the service request module 83 sends the GRE computing power service request message to the target first tunnel endpoint device in the GRE tunnel between the target first tunnel endpoint device and the target second tunnel endpoint device.

[0099] When the client starts up and connects to the second tunnel endpoint device, the target determination module 82 determines the computing power route based on the computing power information. When the target determination module 82 receives a GRE protocol computing power cancellation notification message sent by the target first tunnel endpoint device and / or other first tunnel endpoint devices, it determines a new computing power route based on the computing power information.

[0100] In one embodiment, such as Figure 9 As shown, the first tunnel endpoint device may include a memory 91, a processor 92, a communication interface 93, and a bus 94.
