Problems solved by technology

exist figure 1 In the described network structure, if the plurality of user equipments 14 connected to the access gateway device 13 are all set with the preferred DNS server being the DNS server 111 of ISP1, then all the user equipments 14 will access the network service through the ISP1 access link 113, At this time, the ISP1 access link 113 will be overloaded and congested, reducing the access speed of network services.

Embodiment Construction

[0022] The embodiment of the present invention provides a network service access method and an access gateway device, which can balance the load of the access links of different service providers and improve the access speed of the network service.

[0023] figure 2 It is a flowchart of a network service access method in an embodiment of the present invention. The network service access method in an embodiment of the present invention includes:

[0024] Step 101: Obtain the Internet protocol address of the local domain name resolution server of each Internet service provider that provides services;

[0025] Here, the access gateway device obtains in advance the Internet protocol address of the local domain name resolution server of each ISP providing the service, for example, figure 1 In the network structure shown, the ISPs that provide services include ISP1 and ISP2. The access gateway device 13 is connected to the access link 113 of ISP1 and the access link 123 of ISP2. The access...

Abstract

The embodiment of the invention provides a network service access method, which comprises the following steps of: forwarding a domain name resolution request to local domain name resolution servers of various internet service providers for providing service through access links which correspond to the internet service providers; receiving internet protocol addresses which are related to the domain name resolution request and returned by the local domain name resolution servers of various internet service providers through the corresponding access links; selecting an internet protocol address according to a line state of the access link of each internet service provider for providing service, and returning the selected internet protocol address to user equipment; and accessing network service through the access link of the internet service provider which returns the selected internet protocol address. Correspondingly, the embodiment of the invention also provides access gateway equipment. The embodiment of the invention can balance loads of the access links of different service providers and improve the network service access speed.

Description

Technical field [0001] The present invention relates to the field of communications, in particular to a method for accessing network services and access gateway equipment. Background technique [0002] At present, Internet users can use the access links of multiple Internet service providers (ISP) to access network services. Each ISP will provide users with its own Domain Name System (DNS) server and use DNS services. Convert domain names into Internet Protocol (IP) addresses. In addition, application service providers will also use multiple ISP links to publish their own network services, and use their own intelligent DNS server to take over the domain name resolution work, such as figure 1 As shown, the networks of two ISPs (marked as ISP1 and ISP2 here) used by the application service provider 15 (marked as 112 and 122 here) publish their own network services (such as WEB), and use their own smart DNS server 152 To resolve your own domain name, the domain name resolution rule ...
