[0063] 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 only used to explain the present application and are not used to limit the present application.

[0064] The following will specifically describe the technical solution of the present application and how the technical solution of the present application solves the above technical problems through embodiments and in conjunction with the accompanying drawings. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0065] In addition, the technical solutions described in the embodiments of the present application can be combined arbitrarily without conflict.

[0066] An embodiment of the present application provides a communication method, which is implemented through a client. Figure 1 A flow chart of a communication method provided in an embodiment of the present application Figure 1 .like Figure 1 As shown, in an embodiment of the present application, the communication method applied to the client mainly includes the following steps:

[0067] S101. Send a first message to a link network; the first message is used to find a first server, and the first server is a DHCP server or a DHCPv6 server.

[0068] In an embodiment of the present application, the client may send a first message to the link network to find a first server, that is, a Dynamic Host Configuration Protocol (DHCP) server or a Dynamic Host Configuration Protocol version 6 DHCPv6 server.

[0069] It should be noted that, in the embodiment of the present application, the first server may be a BRAS or an independent server, which is not limited in the embodiment of the present application.

[0070] It should be noted that in the embodiments of the present application, see Figure 2 If the first server that the client searches for is a DHCP server, the first message sent to the linked network may be a Discover message, see Figure 3 If the first server that the client searches for is a DHCPv6 server, the first message sent to the link network may specifically be a solicitation message, and the specific first message is not limited in the application embodiment.

[0071] S102, receiving a second message sent by the first server; the second message is used to provide a first option; wherein the first option includes: a service type of the client, a service identifier assigned to the service type, and a method of assigning the service identifier.

[0072] In an embodiment of the present application, the client sends a first message to find a first server, and the first server can receive the first message in response to a second message. Based on this, the client receives the second message sent by the first server.

[0073] It should be noted that, in the embodiment of the present application, as described in the above step S101, the first message may be a Discover message, and the first server to be found is a DHCP server. In this scenario, see Figure 2 , the second message may be an Offer message, and the first message may be a Solicit message, and the first server to be found is a DHCPv6 server. In this scenario, see Figure 2 The second message may correspond to an Advertise message, and the specific application embodiment of the second message is not limited.

[0074] In an embodiment of the present application, the newly added first option (Option) carried in the second message includes: the service type of the client, the service identifier corresponding to the service type, and the allocation method of the service identifier. If the first server is a DHCP server, the first option is specifically a DHCP Option. If the first server is a DHCPv6 server, the first option is specifically a DHCPv6 Option. Figure 4 The format of the first option shown also includes Option_ServiceID, that is, the option identifier, which is an option identifier reserved and unoccupied for the first server, Option-Len, that is, the option length, Func-Type indicates the allocation method of the service identifier, Func-Len indicates the length of the service identifier, Service-Type indicates the service type, ServiceID indicates the service identifier allocated corresponding to the service type, Preferred-lifetime indicates the preferred lifecycle, and Valid-lifetime is the validity period.

[0075] In an embodiment of the present application, after the client receives the second message sent by the first server, it can also perform the following steps: sending a third message to the first server if the first option is supported; the third message carries the first option; receiving a fourth message sent by the first server; the fourth message is used to indicate that the negotiation of the first option is successful.

[0076] It should be noted that in an embodiment of the present application, the client may not support the first option. If it does not support the first option, it will be ignored. If it does support it, it will send a third message to the first server during the request phase, carrying the first option, and then confirm the success of the negotiation of the first option by receiving the fourth message.

[0077] It should be noted that, in the embodiment of the present application, if the first server is a DHCP server, see Figure 2 , the third message may be a request message, and the fourth message may be an acknowledgment message. If the first server is a DHCPv6 server, see Figure 3 The third message may be a Request message, and the corresponding fourth message may be a Reply message. The specific third message and fourth message are not limited in the application embodiment.

[0078] In an embodiment of the present application, after negotiating a service identifier with the first server, the client may send a service message to the first server; wherein the service message carries service data, service identifier and service type.

[0079] It can be understood that in an embodiment of the present application, a service identifier is provided to the client through the first option. In this way, the service identifier is negotiated between the client and the first server, and the client can choose to provide the service identifier when sending a service message so that the first server can perform differentiated processing based on the service identifier.

[0080] In an embodiment of the present application, after negotiating the service identifier with the first server, the client may also renew the lease of the service identifier, which is described in detail below.

[0081] In an embodiment of the present application, after the client receives the fourth message sent by the first server, the method also includes: sending a fifth message to the first server when the first time is reached; the fifth message is used to request an extension of the time for using the service identifier and carries the service identifier, and the first time is one or more times from the start time to the end time of the service identifier; receiving a sixth message sent by the first server; the sixth message is used to indicate whether the extension of the time for using the service identifier is allowed.

[0082] It should be noted that, in the embodiment of the present application, the first time is one or more times between the start time and the end time of the service identifier. The specific first time can be the middle (50%) time between the start time and the end time. At this time, the client can request the first server to extend the time of using the service identifier. If the request for extension fails, another time before the end time can be determined as the first time. For example, when 7 / 8 (87.5%) of the time between the start time and the end time is reached, the first server is requested to extend the time of using the service identifier again. The specific first time and the number of first times can be determined according to actual needs and application scenarios, and are not limited in the embodiment of the present application.

[0083] It should be noted that, in the embodiment of the present application, if the first server is a DHCP server, see Figure 5 , the fifth message may be a Request message, and the sixth message may be an Ack message. If the first server is a DHCPv6 server, see Figure 6 The fifth message may be a Renew message, and the sixth message may be a Reply message. If the Reply message indicates that the service identifier is not allowed to be extended, the client may send a Rebind message again to request again. In this case, the fifth message is Rebind, and the sixth message is a Reply message. The specific fifth message and the sixth message are not limited in the present application embodiment.

[0084] In an embodiment of the present application, after negotiating the service identifier with the first server, the client can also use the service identifier to release the service identifier. Specifically, after the client receives the fourth message sent by the first server, it can also perform the following steps: send a seventh message to the first server; the seventh message is used to request the release of the service identifier.

[0085] It should be noted that, in the embodiment of the present application, if the first server is a DHCP server, see Figure 7 , the seventh message can be a Release message. In this case, the client can also send a Decline message to the DHCP server, stating that the user address has been used or is invalid. When applying for address release, the service identifier will also be released. Then, the client receives an Ack message sent by the DHCP server. If the first server is a DHCPv6 server, see Figure 8 The seventh message may also be a Release message. In this case, the client may receive a Reply message sent by the DHCPv6 server, and then send a Decline message, and then receive an Ack message sent by the DHCPv6 server. The specific seventh message is not limited to the embodiment of the application.

[0086] An embodiment of the present application provides a communication method, which is applied to a first server, where the first server is a DHCP server or a DHCPv6 server. Fig. 9 A communication method according to an embodiment of the present invention is provided.

[0093] It should be noted that, in the embodiment of the present application, as described in the above-mentioned client-side method steps, if it supports the first option, a third message can be sent to the first server, and the first server can receive the third message sent by the client, and respond to the client with a fourth message. The relevant explanations of the third message and the fourth message are detailed in the above-mentioned client-side method steps, and will not be repeated here.

[0094] In an embodiment of the present application, after the first server sends the fourth message to the client, the following steps may also be performed: receiving a business message sent by the client; wherein the business message carries business data, business identification and business type; based on the business identification and business type, allocating a network channel for the business data; and forwarding the business data through the network channel.

[0095] It can be understood that in an embodiment of the present application, after the negotiation of the service identifier is realized, the service message carrying the service type and the negotiated service identifier is forwarded to the first server. The first server can distinguish the priority of the service data according to the service identifier and the service type, and forward the service data to the network channel of the corresponding service level to realize differentiated service for the service.

[0096] In an embodiment of the present application, after the first server sends the fourth message to the client, the following steps may also be performed: receiving the fifth message sent by the client; the fifth message is used to request an extension of the time for using the service identifier; sending a sixth message to the client; the sixth message is used to indicate whether the extension of the time for using the service identifier is allowed.

[0097] It should be noted that, in the embodiment of the present application, as described in the above-mentioned client-side method steps, the client can send a fifth message to the first server when it is necessary to delay the use of the service identifier, and the first server can receive the fifth message sent by the client and respond to the client with a sixth message. The relevant explanations of the fifth message and the sixth message are detailed in the above-mentioned client-side method steps, which will not be repeated here.

[0098] In an embodiment of the present application, after the first server sends the fourth message to the client, the following steps may also be performed: receiving the seventh message sent by the client; the seventh message is used to request the release of the service identifier; based on the seventh message, the service identifier is released.

[0099] It should be noted that in the embodiment of the present application, as described in the above client side method steps, when the client needs to release the service identifier, it can send a seventh message to the first server to request the first server to release the service identifier. The relevant explanation of the seventh message is detailed in the above client side method steps, which will not be repeated here.

[0100] Based on the communication method between the above-mentioned client side and the first server side, it can be known that the technical solution provided in the embodiment of the present application automatically negotiates the service identifier between the client and the DHCP server or DHCPv6 server, does not rely on end-to-end human management intervention, is simple to deploy, and is convenient for operation and maintenance. The DHCP server or DHCPv6 server automatically schedules traffic based on the service identifier, no longer relies on complex configuration, and the configuration does not need to be changed after the user goes online again and the address changes, so the service deployment is convenient and error-prone.
