The task processing method of the embodiment can be applied to network equipment. FIG. 2 is a system architecture diagram of a task processing method application according to an embodiment of the present invention; as shown in fig. 2, the system may include a terminal device 11 and a network device; the terminal device 11 may also be referred to as a client. Each network device can have computing resources, network resources and storage resources; wherein, the computing resources can also be called computing functions, the network resources can be called network transmission functions, and the storage resources can be used for storing data. It can be understood that each network device in this embodiment has a certain computing function, and can perform corresponding computing function for data; each network device in this embodiment may also have a network transmission function, and data transmission may be performed between network devices or between the terminal device 11 and an access network device; each network device in this embodiment also has a storage function, and can store specific data.
In this embodiment, the network device may be divided into an access node device 12 and a service node device 13 according to functional division; there may be one or more functional modules in the service node device 13, each of which may be used for processing a function. As an embodiment, the functional module may include a computer program, and the corresponding function is realized by executing the computer program. For example, a certain service node 13 has a functional module, which includes a face recognition algorithm, and can be used for recognizing a face image through executing the face recognition algorithm. Of course, the function of the functional module in the present embodiment is not limited to the above example, and any other functions are within the protection scope of the present embodiment.
In this embodiment, the function of the function module in the service node device 13 may be referred to as a computing function, or may be referred to as computing power, that is, the service node device 13 may have computing capabilities of various functions. The computing capability may be preset in the service node device 13, that is, the function module is preset in the service node device 13; alternatively, the computing capability may be provided in an external device connected to the service node device 13, that is, the function module may be provided in an external device connected to the service node device 13.
In this embodiment, the functional modules in the service node device 13 may be at least partially the same or different. For example, as shown in fig. 2, one service node device 13 has a function module 1(Func1) and a function module 2(Func 2); the other service node device 13 has a function module 3(Func3) and a function module 4(Func 4); wherein, the function module 1(Func1) and the function module 2(Func2) have different functions; function module 3(Func3) and function module 4(Func4) have different functions; the function modules 1(Func1) and 2(Func2) are completely different functions from the function modules 3(Func3) and 4(Func4), or have partially the same function, for example, the function module 2(Func2) and the function module 3(Func3) have the same function.
The task processing method of this embodiment is applied to the access node device 12, that is, the access node device 12 receives a task request of the terminal device 11, where the task request includes a first Service identifier (Service ID) or a first Function identifier (Function ID). As an implementation manner, the terminal device may determine a service identifier or a function identifier according to a service type of data to be transmitted (the determined service identifier is denoted as a first service identifier, and the determined function identifier is denoted as a first function identifier). Wherein the service identification and the function identification are related to the service type. In practical application, a mapping relationship between a service type and a service identifier may be preset in the terminal device, or a mapping relationship between a service type and a function identifier may be set, and after the service type corresponding to the data packet is determined, the corresponding first service identifier or first function identifier may be determined based on the service type.

Illustratively, the mapping relationship between the service identifier and the function identifier and the mapping relationship between the function identifier and the network address, which are sent by the service network node, may be obtained through the routing table update message.
In an optional embodiment of the present invention, in a case that the task request includes the first function identifier, the first network address corresponding to the first function identifier may be determined based on a mapping relationship between the function identifier and the network address, so as to determine the network device corresponding to the first network address.

Wherein the determining at least one target network device corresponding to the at least one first function identifier includes: determining at least one first network address corresponding to at least one first function identifier based on a mapping relation between the function identifiers and the network addresses obtained in advance; and determining at least one target network device corresponding to the at least one first network address.
In an optional embodiment of the invention, the method further comprises: obtaining the mapping relation between the service identifier and the function identifier and/or the mapping relation between the function identifier and the network address in the network equipment through the routing table updating message; the network address is a network address of the network device.
In this embodiment, any network device (for example, the service node device 13) may broadcast a routing table update message to surrounding network devices in a broadcast manner, where a specific field or a reserved field in the routing table update message carries a mapping relationship between a service identifier and a function identifier in the service node device and/or a mapping relationship between a function identifier and a network address; the network device receiving the routing table updating message can add the mapping relation between the service identifier and the function identifier of the network device and/or the mapping relation between the function identifier and the network address in the routing table updating message to generate a new routing table updating message and further broadcast the routing table updating message; the access node device 12 receives the routing table update message broadcast by other network devices, and may sort the mapping relationship between the service identifier and the function identifier and/or the mapping relationship between the function identifier and the network address carried in the received routing table update message, to obtain the mapping relationship between the service identifier and the function identifier and/or the mapping relationship between the function identifier and the network address corresponding to the surrounding service node devices.
As an embodiment, the mapping relationship between the service identifier and the function identifier and/or the mapping relationship between the function identifier and the network address in the network device may be obtained through a Border Gateway Protocol (BGP) message. As an example, the mapping relationship between the service identifier and the function identifier and/or the mapping relationship between the function identifier and the network address may be carried in a TLV format in a path attributes (path attributes) field in a BGP update (BGP update) message shown in table 1 below; wherein T in TLV represents a type of data (Tag), L represents a Length of data (Length), and V represents a Value of data (Value). As another example, the service identifier and/or the function identifier may also be carried in a TLV format in a path attributes (path attributes) field in a BGP update (BGP update) message; the network equipment receiving the BGP upgrade (BGP update) message can determine the mapping relation between the service identifier and the function identifier according to the service identifier and the function identifier carried in the message; determining a mapping relation between the function identification and the network address based on the source network address corresponding to the message; or, the network device that receives the BGP update (BGP update) message may determine, according to the service identifier carried in the message, a mapping relationship between the function identifier and the network address based on a mapping relationship between the service identifier and the function identifier that are configured in advance, and the source network address corresponding to the message.
