[0031] To make the objectives, technical solutions, and advantages of this disclosure more apparent, exemplary embodiments according to this disclosure will now be described in detail with reference to the accompanying drawings.

It should be understood that this disclosure is not limited to the exemplary embodiments described herein.
[0032] Figure 1a schematically illustrates an environmental application diagram according to an embodiment of the present disclosure.
[0033] As shown in Figure 1a, the data center network 100 may include a first network device 101 and a second network device 102. The first network device 101 and the second network device 102 can perform real-time data transmission.
[0034] The first network device 101 can generate data and send it to the second network device 102. The first network device 101 can also receive data, such as data sent by the second network device 102. The first network device 101 can include any type of electronic device, such as mobile devices, servers, routers, tablets, laptops, workstations, virtual reality devices, gaming devices, set-top boxes, digital streaming media devices, vehicle terminals, smart TVs, etc. No limitations are imposed.
[0035] The second network device 102 can generate data and send it to the first network device 101. The second network device 102 can also receive data, such as data sent by the first network device 101. The second network device 102 can include any type of electronic device, such as mobile devices, servers, routers, tablets, laptops, workstations, virtual reality devices, gaming devices, set-top boxes, digital streaming media devices, vehicle terminals, smart TVs, etc. No limitations are imposed.
[0036] In some embodiments, the first network device 101 can send data information to the second network device 102 via relevant protocols. For example, the first network device 101 can send a neighbor request message to the second network device 102 according to a neighbor discovery protocol. The second network device 102 can receive the neighbor request message and send a neighbor advertisement message in response. The first network device 101 can receive the neighbor advertisement message. Thus, information communication between the first network device 101 and the second network device 102 can be realized.
[0037] Figure 1b schematically illustrates another environmental application diagram according to an embodiment of the present disclosure.
[0038] As shown in Figure 1b, it includes Host device 103, Access device 104, Spin device 105, and Core device 106.
[0039] Host device 103 may be configured with a location identifier (SRv6 Locator) and / or capability information (SRv6 Capability). Access device 104 may also be configured with an SRv6 Locator and / or SRv6 Capability. In some embodiments, Host device 103 and Access device 104 may transmit SRv6 Locators and / or SRv6 Capabilities to each other via a first network protocol, so that the other can obtain its own SRv6 Locator and / or SRv6 Capability.
[0040] In some embodiments, Spin device 105 can learn the SRv6 Locator and / or SRv6 Capability of Host device 103 via Access device 104 through Interior Gateway Protocol (IGP). Core device 106 can learn the SRv6 Locator and / or SRv6 Capability of Host device 103 through Border Gateway Protocol (BGP). This achieves the effect of dynamically publishing the routing information of Host device 103 throughout the network.
[0041] Figure 2 schematically illustrates a flowchart of a data transmission method according to an embodiment of the present disclosure.
[0042] As shown in Figure 2, the data transmission method of this embodiment is applied to a first network device and includes step S201:
[0043] S201. Send first information through a first network protocol; wherein the first information carries at least network address information and / or network performance information of the first network device, and the first network protocol includes at least a network layer protocol and / or a link layer protocol.
[0044] In this embodiment of the disclosure, the first network device can send the first information at the link layer via a link protocol, and / or at the network layer via a network layer protocol. Therefore, the first information can be sent simultaneously or separately according to existing network deployment protocols, thereby ensuring the timely and dynamic publication of the first network device's network address information and / or network performance information.
[0045] In this embodiment of the disclosure, the first information includes the network address information of the first network device. The network address information can be a unique identifier for the first network device across the entire network. This network address information allows for accurate location of the first network device within the network. Alternatively, the network address information can be routing information for the first network device. The first network device can use this routing information to guide the routing and forwarding of data packets within the network.
[0046] In this embodiment of the disclosure, the first information includes network performance information of the first network device. This network performance information can be used to indicate the device functions of the first network device. For example, it can identify the SRv6 capability supported by the first network device. Through the network performance information, the first network device can indicate to other devices in the network whether it supports SRv6 technology and the specific SRv6 functionalities it supports.
[0047] In this embodiment of the disclosure, a first network device sends first information using network layer protocols and / or link layer protocols. This allows other network devices to obtain the network address information and / or network performance information of the first network device from the first information based on the network layer protocols and / or link layer protocols. Consequently, the network address information and / or network performance information of the first network device can be dynamically published to other network devices.
[0048] In this embodiment of the disclosure, the network layer protocol includes a neighbor discovery protocol; the link layer protocol includes a link layer discovery protocol.
[0049] In this embodiment, the first network device can send data information at the network layer according to a neighbor discovery protocol. The second network device can receive the data information sent by the first network device according to a neighbor discovery protocol. Furthermore, the first network device can also receive data information sent by other network devices according to a neighbor discovery protocol. For example, the first network device sends data information to the second network device according to the neighbor discovery protocol. After receiving the data information sent by the first network device via the neighbor discovery protocol, the second network device sends response data information to the first network device according to the neighbor discovery protocol. Further, the first network device can receive the response data information sent by the second network device.
[0050] Therefore, through the neighbor discovery protocol, the first and second network devices can exchange information. This allows them to publish their own network address information and / or network performance information in real time, while also dynamically receiving network address information and / or network performance information from other network devices, ensuring the accuracy and timeliness of the information.
[0051] In this embodiment, the first network device can also send data information at the link layer according to the link layer discovery protocol. Furthermore, the first network device can also receive data information sent by the second network device through the link layer discovery protocol. Thus, the first network device can dynamically publish network address information and / or network performance information through the link layer discovery protocol.
[0052] Through the embodiments of this disclosure, the first network device and the second network device can communicate data at the network layer and / or link layer using corresponding protocols. The two different layer neighbor discovery protocols and link layer discovery protocols do not conflict with each other. This allows the network device to choose to discover the two protocols simultaneously or separately based on existing deployed protocols. Consequently, the network address information and / or network performance information of the network device can be published through multiple channels, thereby ensuring the dynamic publication of network address information and / or network performance information by the network device.
[0053] In this embodiment of the disclosure, the neighbor discovery protocol may include a neighbor request message. The neighbor request message carries the network address information and / or network performance information of the first network device.
[0054] In this embodiment of the disclosure, a first network device may send a neighbor request message. The neighbor request message carries the network address information and / or network performance information of the first network device. A second network device may receive the neighbor request message sent by the first network device, thereby obtaining the network address information and / or network performance information of the first network device.
[0055] Furthermore, the second network device can send a neighbor advertisement message to the first network device based on a neighbor request message. This neighbor advertisement message may carry the network address information and / or network performance information of the second network device. The first network device can receive the neighbor advertisement message to obtain the network address information and / or network performance information of the second network device.
[0056] In some embodiments, the first network device may also receive neighbor request messages. For example, it may receive a neighbor request message sent by a second network device. The neighbor request message sent by the second network device may carry the network address information and / or network performance information of the second network device. Therefore, the first network device can obtain the network address information and / or network performance information of the second network device based on the neighbor request message.
[0057] In some embodiments, the first network device may also send a neighbor advertisement message in response to a neighbor request message sent by another network device, such as a second network device. The neighbor advertisement message may carry the network address information and / or network performance information of the first network device. This allows other network devices to obtain the network address information and / or network performance information of the first network device based on the neighbor advertisement message.
[0058] In this embodiment of the disclosure, the network address information of the first network device includes the location identifier SRv6 Locator of the first network device; and the network performance information of the first network device includes the capability information SRv6 Capability of the first network device.
[0059] In this embodiment of the disclosure, the SRv6 Locator of the first network device can be used to identify the first network device, as well as routing information for identifying the first network device. In some embodiments, different network devices have different SRv6 Locators, and different SRv6 Locators are used to identify different network devices.
[0060] The SRv6 Locator can also identify routing information for network devices. For example, a second network device obtains the SRv6 Locator of a first network device and, based on the first network device's SRv6 Locator, retrieves its routing information. Furthermore, it can update its own SRv6 Locator routing table based on the received routing information, ensuring the accuracy and timeliness of routing.
[0061] It is understandable that the first network device can also obtain the SRv6 Locator of the second network device, and obtain the routing information of the second network device based on the SRv6 Locator of the second network device.
[0062] In this embodiment of the disclosure, the SRv6 Capability of the first network device can be used to identify whether the first network device supports SRv6 and the specific functions of SRv6 supported.
[0063] In this embodiment of the disclosure, the SRv6 Locator and SRv6 Capability of the first network device are carried in the first network protocol. This first network protocol enables the first network device and the second network device to obtain each other's SRv6 Locator and SRv6 Capability. Therefore, dynamic publishing and timely updating of routing information can be achieved.
[0064] In this embodiment of the disclosure, network address information and / or network performance information of the first network device are configured.
[0065] In this embodiment of the disclosure, the SRv6 Locator and / or SRv6 Capability can be statically configured on the first network device. For example, the controller can assign the SRv6 Locator and / or SRv6 Capability to the host device via a network configuration protocol.
[0066] In this embodiment of the disclosure, the SRv6 Locator of the first network device includes one or more of the following: a type identifier of the SRv6 Locator of the first network device, a length of the SRv6 Locator of the first network device, a metric value of the SRv6 Locator of the first network device, a positioning length of the SRv6 Locator of the first network device, and a variable length identifier of the SRv6 Locator of the first network device.
[0067] In this embodiment of the disclosure, the SRv6 Locator includes a type identifier (Type), a length (Length), a metric (Metric), a location length (Locator Size, LOC Size), a variable length identifier (Locator), etc.
[0068] In this embodiment of the disclosure, Type is used to indicate the type of SRv6 Locator. The Type of the SRv6 Locator of the first network device can identify that the option information is SRv6 Locator information. In some embodiments, the specific value of the Type of the SRv6 Locator of the first network device can be assigned by the Internet Assigned Numbers Authority (IANA). In some embodiments, Type can occupy 8 bits.
[0069] In this embodiment of the disclosure, Length represents the total length of the SRv6 Locator. In some embodiments, Length may occupy 8 bits.
[0070] In this disclosure, the metric can be used to evaluate the quality of the SRv6 path. In some embodiments, the metric occupies 32 bits.
[0071] In this embodiment of the disclosure, LOC Size can be used to indicate the length of the portion of the SRv6 Locator used for positioning. In some embodiments, LOC Size occupies 8 bits.
[0072] In this embodiment of the disclosure, the Locator(variable) can be used to indicate the variable portion of the SRv6 Locator. For example, it can be used to identify the value of the SRv6 Locator.
[0073] In this embodiment of the disclosure, the SRv6 Capability of the first network device includes one or more of the following: the type identifier of the SRv6 Capability of the first network device and the length of the SRv6 Capability of the first network device.
[0074] In this embodiment of the disclosure, SRv6 Capability includes a type identifier (Type), a length (Length), etc.
[0075] In this embodiment of the disclosure, Type is used to indicate the type of SRv6 Capability. The Type of the SRv6 Capability of the first network device can identify that the option information is SRv6 Capability information. In some embodiments, the specific value of the Type of the SRv6 Capability of the first network device can be assigned by the Internet Assigned Numbers Authority (IANA). In some embodiments, Type can occupy 8 bits.
[0076] In this embodiment of the disclosure, Length represents the total length of the SRv6 Capability. In some embodiments, Length may occupy 8 bits.
[0077] Figure 3 schematically illustrates a flowchart of another data transmission method according to an embodiment of the present disclosure.
[0078] As shown in Figure 3, the data transmission method of this embodiment is applied to a second network device and includes step S301:
[0079] S301. Receive first information through a first network protocol; wherein the first information carries at least network address information and / or network performance information of the first network device, and the first network protocol includes at least a network layer protocol and / or a link layer protocol.
[0080] In this embodiment of the disclosure, the second network device can receive information from the first network device via a first network protocol.
[0081] In this embodiment of the disclosure, the second network device may receive the first information at the network layer via a network layer protocol, and / or at the link layer via a link layer protocol.
[0082] Through the embodiments of this disclosure, using a first network protocol, a second network device can obtain the network address information and / or network performance information of the first network device. This enables the dynamic publication of relevant information from the first network device.
[0083] In this embodiment of the disclosure, the second network device may also send second information via a second network protocol. The second information carries at least the network address information and / or network performance information of the second network device, and the second network protocol includes at least a network layer protocol and / or a link layer protocol.
[0084] In this embodiment of the disclosure, the second network device can send second information via a second network protocol. The first network device can receive the second information via the second network protocol and obtain the network address information and / or network performance information of the second network device from it.
[0085] In this embodiment of the disclosure, the second network device can send the second information at the network layer via a neighbor discovery protocol. And / or, the second network device can send the second information at the link layer via a link layer discovery protocol.
[0086] In this embodiment of the disclosure, the second network device can send a neighbor advertisement message via a neighbor discovery protocol. In some embodiments, the neighbor advertisement message includes the network address information and / or network performance information of the second network device. The first network device can receive the neighbor advertisement message and obtain the network address information and / or network performance information of the second network device from it.
[0087] In this embodiment of the disclosure, the network address information of the second network device includes the SRv6 Locator of the second network device. The network performance information of the second network device includes the SRv6 Capability of the second network device.
[0088] In this embodiment of the disclosure, the first network device may send a neighbor request message and / or a link layer discovery protocol, carrying its SRv6 Locator and SRv6 Capability. The second network device may receive the neighbor request message and / or link layer discovery protocol sent by the first network device and obtain its SRv6 Locator and SRv6 Capability from it.
[0089] The second network device can also send neighbor advertisement messages and / or link layer discovery protocols. It carries the second network device's SRv6 Locator and SRv6 Capability in the neighbor request message and / or link layer discovery protocol. The first network device can receive the neighbor advertisement message and / or link layer discovery protocol sent by the second network device and obtain the second network device's SRv6 Locator and SRv6 Capability from them.
[0090] In some embodiments, the second network device may also send a neighbor request message. The neighbor request message carries the second network device's SRv6 Locator and SRv6 Capability. It sends its own SRv6 Locator and SRv6 Capability to other devices via the neighbor request message.
[0091] Figure 4 schematically illustrates a flowchart of another data transmission method according to an embodiment of the present disclosure.
[0092] As shown in Figure 4, the data transmission method further includes step S401:
[0093] S401. Send the first information to the third network device through the second network protocol, so that the first information can be sent to the fourth network device via the third network device.
[0094] In this embodiment of the disclosure, the second network device sends the first information to the third network device via a second network protocol. The first information is then sent to the fourth network device via the third network device. Alternatively, the second network device can also send the first information to the fourth network device via the second network protocol.
[0095] In some embodiments, the second network protocol may be an interior gateway protocol, the third network device may be a backbone device, and the fourth network device may be a core device.
[0096] For example, after the second network device acquires the SRv6 Locator and SRv6 Capability of the first network device, the backbone devices can learn the SRv6 Locator and SRv6 Capability of the first network device through the Interior Gateway Protocol (IGP). The core devices can learn the SRv6 Locator and SRv6 Capability of the first network device through the Border Gateway Protocol (BGP). This allows the entire network to learn the SRv6 Locator and SRv6 Capability of the first network device.
[0097] In this embodiment of the disclosure, the third network device may also be a host device or an access device. The fourth network device may also be a host device or an access device. In this embodiment of the disclosure, the first network device may be a host device or an access device. The second network device may be a host device or an access device.
[0098] For example, the first network device, the second network device, the third network device, and the fourth network device can all be host devices. Then, the first network device can send first information to the second, third, and fourth network devices via the first network protocol. The second, third, and fourth network devices receive the information via the first network protocol and learn the first network device's SRv6 Locator and SRv6 Capability from it.
[0099] Furthermore, the second network device can also send second information to the first network device, the third network device, and the fourth network device via the first network protocol. The first, third, and fourth network devices can learn the SRv6 Locator and SRv6 Capability of the second network device based on the second information sent by the second network device.
[0100] Understandably, a host device can be a device connected to an access device in the network. For example, in an enterprise network, if a user terminal is connected to an access device through a switch, then both the user terminal and the switch can be considered host devices. Alternatively, if a user terminal is connected to a switch, then the user terminal can be a host device, and the switch can be an access device.

[0107] As shown in FIG7, a computer program product 700 according to an embodiment of the present disclosure includes a computer program 701, which implements the data transmission method described above when executed by a processor.
[0108] The above description, with reference to the accompanying drawings, illustrates a data transmission method, network device, storage medium, and computer program product according to embodiments of the present disclosure. The first network device transmits first information at the network layer via a network layer protocol. And / or, the first network device transmits first information at the link layer via a link layer protocol. This allows other network devices to learn the SRv6 Locator and SRv6 Capability of the first network device based on the first information.
