[0050] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0051] Embodiment 1: This application discloses a method for acquiring network configuration parameters based on service type.

[0052] For details, please refer to Figure 1a , a method for obtaining network configuration parameters based on service type disclosed in this embodiment includes the following steps:

[0053] Step 101: Send a message including the client service type to request the server to allocate network configuration parameters.

[0054] In the method described in this embodiment, when the client starts up, it will send a message (DHCP-DISCOVERY message) in the form of broadcast to request the server to assign it Dynamic Host Configuration Protocol DHCP (Dynamic Host Configuration Protocol) information such as IP address and gateway.

[0055] As an optional method, the format of the DHCP message is as follows: Figure 1b As shown, op represents the operation type of the message, which can be divided into request messages (messages in which the client requests the allocation of network configuration parameters, such as DHCP-DISCOVERY messages) and response messages (messages in which the server provides network configuration parameters, such as the response messages in this application). This field can be specifically divided into request messages and response messages according to the value. For example, if the field is set to 1, it means a request message, and if the field is set to 2, it means a response message. htype and hl en respectively represent the hardware address type and length of the client. hops represents the number of DHCP relays (i.e., gateways) that the DHCP message passes through. Specifically, the value of the hops field will increase by 1 for each DHCP relay that the DHCP request message passes through.

[0056] xi d indicates the random number selected when the client initiates a request, which is used to identify an address request process. secs indicates the time after the client starts to request the allocation of network configuration parameters, which can be increased by default from 0. The first bit of flags is the broadcast response flag, which is used to identify whether the server responds to the message in unicast or broadcast mode. Specifically, this field can be set to 0 to indicate unicast mode, and set to 1 to indicate broadcast mode. c iaddr indicates the IP address of the client. Specifically, if the client has a legal and available IP address, it is added to this field, otherwise the field is set to 0. It should be noted that this field is not used by the client to apply for a specific IP address. yi addr indicates the IP address assigned by the server to the client. si addr indicates the server IP address from which the client obtains the startup configuration information. gi addr indicates the IP address of the first DHCP relay that the client passes through after sending the request message, that is, the gateway address. chaddr indicates the hardware address of the client. sname indicates the server name from which the client obtains the startup configuration information. file indicates the startup configuration file name and path information specified by the server for the client.

[0057] Options is an option field, which contains configuration information such as the service type and valid lease of the message. According to the definition of the options field in standards such as RFC2132, the 0-255 of this field represents different options, among which 224-254 can be modified and used by the user. In the method described in this embodiment, as an example, option 224 can be used to carry the service type, and its format includes: Option, Length, ServiceType and priority. Among them, Option occupies 1 byte and has a value of 224. Length is the length field, which occupies 1 byte and has a value of 2.

[0058] Among them, ServiceType represents the service type, which occupies 1 byte. Specifically, the value of this field can be set to distinguish different service types, for example, 0 is the default service, 1 is the voice service, 2 is the video service, etc., and a total of 256 service types can be set. Priority is the priority, which occupies 1 byte and represents the degree of matching between the service that the gateway configured by the server can handle and the service type. Specifically, the value of this field can be set to 255 to represent the highest matching degree, a value of 1 represents the lowest matching degree, and a value of 0 represents reservation, etc. In the method described in this embodiment, there is no specific limitation on the content of the field, which can be a value or a letter, for example, the letter H represents the highest matching degree, and the letter V represents the video service, etc. It can represent the field and implement the method described in this embodiment.

[0059] Step 102: Receive a response message from the server.

[0060] In the method described in this embodiment, the server receives a message from the client, parses it to obtain the ServiceType field, i.e., the client service type. It matches it with the services that the gateway configured by the server itself can handle, obtains the degree of match, writes it into a response message (DHCP-OFFER message), and sends it to the client. In the method described in this embodiment, the format of the DHCP-OFFER message refers to Figure 1b The format is where the degree of matching is the content of the priority field described above.

[0061] As an optional method, the matching degree is a numerical value. When the client service type is the same as the service that the gateway configured by the server can handle, the matching degree is set to a first numerical value. When the client service type is different from the service that the gateway configured by the server can handle, the matching degree is set to a second numerical value that is less than the first numerical value. For example, the client service type is a voice service, and when the service that the gateway configured by the server can handle is a voice service, the two are the same, and the matching degree can be set to 250. When the service that the gateway configured by the server can handle is a video service, the two are different, and the matching degree can be set to a value lower than 250, such as 10. When the service that the gateway configured by the server can handle is a general service, the two are different. However, in actual work, the gateway that handles general services also has the ability to handle voice services, but its adaptability to voice services is lower than that of the gateway that handles voice services. At this time, the matching degree can be set to a value lower than 250 but higher than 10, such as 100.

[0062] Step 103: Select the server corresponding to the response message whose matching degree meets the preset requirement as the target server.

[0063] In the method described in this embodiment, there may be multiple servers, and the client will receive response messages from multiple servers. The client parses these response messages, obtains multiple matching degrees, and selects the server corresponding to the response message with the highest matching degree value. For example, the client receives three DHCP-OFFER messages, compares the priority field in option 224 in the three DHCP-OFFER messages, selects the DHCP-OFFER message with the largest field value, and uses the server corresponding to it as the target server.

[0064] Step 104: Acquire the network configuration parameters from the target server.

[0065] In the method described in this embodiment, after the client selects the target server, it sends a request message (DHCP-REQUEST message) including the target server identifier in the form of a broadcast. Upon receiving the request message, the target server interacts with the client so that the client can obtain network configuration parameters, and all subsequent messages sent by the client are directly sent to the target server. When other servers except the target server receive the request message, they stop interacting with the client. As an optional method, the target server identifier in the DHCP-REQUEST message can be the IP address, gateway and other network configuration parameters provided by the target server, or it can be the IP address of the target server. Its content can serve to indicate that the target server has been selected, and the specific content of the target server identifier is not limited here.

[0066] In the method described in this embodiment, Figure 1c This is a timing diagram of data transmission between the client and the server disclosed in the embodiment of this application. As an optional method, Figure 1c As shown in the figure, the client first sends a DHCP-DISCOVERY message containing a ServiceType field with a value. After receiving it, the server processes it, fills in the value of the priority field, and sends a DHCP-OFFER message containing the priority field to the client. After receiving it, the client compares the values ​​and sends a DHCP-REQUEST message containing the target server identifier. After receiving the DHCP-REQUEST message, the server determines whether the target server is itself.

[0067] In the method described in this embodiment, the server knows the types of services that its configured gateway can handle, and the processing adaptability of the gateway to each service is usually preset during network planning and deployment. For example, a router connected to the Internet via a mobile network has limited bandwidth but low latency, which is suitable for processing language services. The network bandwidth of broadband connection to the Internet is large, but the latency cannot be guaranteed, which is suitable for big data services such as video. The server and gateway in the method described in this embodiment can be deployed together or separately. This application does not make specific limitations on this, and it is sufficient to be able to implement the method described in this application.

[0068] The method described in this embodiment supports the client to carry its own service type in the message through the content of the custom field, so that the server can judge the degree of service adaptation between the client and the configured gateway through the service type. The server is supported to return a message carrying the degree of adaptation, so that the client can flexibly select a server according to service requirements in a multi-server scenario and obtain network configuration parameters from the server. In this way, the services of the client and the server gateway are highly adapted to each other and the service experience is improved.

[0069] Embodiment 2: This application discloses another method for obtaining network configuration parameters based on service type, please refer to Figure 2 , the method described in this embodiment introduces the whole process of obtaining network configuration parameters.

[0070] Step 201: A client whose service type is voice service sends a message including the service type in a broadcast form to request to obtain network configuration parameters.

[0071] Step 202: Server A configured with a gateway that is good at processing video services, server B configured with a gateway that is good at processing general services, and server C configured with a gateway that is good at processing voice services all receive the message.

[0072] Step 203: Server A parses the message, obtains the matching degree between the voice service and the video service, writes the matching degree into a response message in the form of a value of 5, and sends it to the client.

[0073] Step 204: Server B parses the message, obtains the matching degree between the voice service and the general service, writes the matching degree into a response message in the form of a value of 150, and sends it to the client.

[0074] Step 205: Server C parses the message, obtains the matching degree between the voice service and the voice service, writes the matching degree into a response message in the form of a value of 250, and sends it to the client.

[0075] Step 206: The client parses the three response messages, compares the values ​​of the matching degrees therein, and obtains the server C corresponding to the matching degree with the largest value.

[0076] Step 207: The client writes the identifier of server C into the request message and sends it in the form of broadcast.

[0077] Step 208: Server A and server B receive the request message and stop interacting with the client.

[0078] Step 209: Server C receives the request message, interacts with the client, and receives all subsequent messages from the client.
