Embodiment 1

[0020] In the existing IPTV system, due to the need to deploy an independent configuration server VCDS, and the client needs to perform complex interactions with the configuration server through the DHCP server and DNS server to obtain the information of the network service server, such as the address information of the network service server , so it not only introduces a new point of failure, but also needs to modify the equipment already deployed in the network, which increases the investment cost and operation cost of the IPTV system. In the embodiment of the present invention, a simplified DHCP device is provided, which can directly provide the information of the network service server to the client, thereby greatly simplifying the deployment of the IPTV system. The simplified DHCP device is an independent network device or is added to an existing network device, for example, a network device supporting a fast channel switching server function. Preferably, it is attached t...

Embodiment 2

[0040] figure 2 A schematic flowchart of a method according to an embodiment of the present invention is shown.

[0041] figure 2 Steps 110, 120 in figure 1 The steps are the same as in , so I won't repeat them here.

[0042] In step 130, the client acquires the information of the network service server according to the first response of the simplified DHCP device. In the first embodiment, the detailed information about the network service server is carried in the first response, so the client can use the detailed information to directly start the IPTV service interaction with the network service server. In this embodiment, the first response may also only carry simple information about the network service server, and the client may select the network service server according to the simple information and further obtain detailed information about the selected network service server. For example, the first response includes the IP address and identification information of...

Embodiment 3

[0047] image 3 A schematic flowchart of a method according to an embodiment of the present invention is shown.

[0048] It can be seen that the method according to this embodiment includes the following steps:

[0049] 310. The simplified DHCP device receives a DHCP Discover broadcast request sent by the client, where the broadcast request includes a request for information about the network service server. As mentioned in the previous embodiment, the client can indicate the request for the information of the network service server through the agreed option (Option) in the broadcast request, and can also use a new Option to indicate the request for the information of the network service server, Or other ways that those skilled in the art can think of can also be used to indicate the request.

[0050] 320. The simplified DHCP device sends the first response including the information of the network service server to the client, so that the client obtains the information of th...

Abstract

The embodiment of the invention discloses a method for obtaining information of a network business server. The method comprises the following steps: a client sends a DHCP (dynamic host configuration protocol) discovery broadcast request, wherein the broadcast request includes a request for the IP (Internet protocol) address of the client and a request for the information of the network business server; the client receives a DHCP offer message sent by the DHCP server, and obtains the IP address of the client according to the IP address information of the client included in the DHCP offer message; and the client receives the simplified first response sent by the DHCP device, and obtains the information of the network business server according to the information of the network business server, which is contained in the first response.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a method for obtaining server information in network services (such as Internet Protocol Television (IPTV) services), a client and an automatic host configuration protocol (Dynamic Host Configuration Protocol) , DHCP) device. Background technique [0002] In network services, in order to improve the service experience of users, it is usually necessary to deploy network service servers, such as network service servers for providing fast channel switching, packet loss retransmission servers for solving packet loss and retransmission problems, and so on. Taking the IPTV service as an example, a Video Quality Experience Server (Video Quality Experience Server, VQE Server) is set in the prior art. In order to enable the user to obtain a good video experience, it is necessary for the user to know the address of the network service server in advance. [0003] In the pri...
