Embodiment Construction

[0039]Aiming at the problems existing in the prior art, an embodiment of the present invention provides a service access method, which is applied to a system including at least one terminal device, a load balancing device and at least two servers. The terminal device can be a PC on the intranet of the enterprise, and the PC accesses the services of the server through the domain name. In order to ensure business reliability and response performance, servers with the same business functions are deployed in different ISP networks, and the server IDs of the servers deployed in different ISP networks are different; load balancing devices are connected to different ISP networks through different Interact with servers in the ISP network through the ISP network respectively.

[0040] by figure 2 It is a schematic diagram of the application scenario of the embodiment of the present invention. In this application scenario, two ISP networks are taken as an example for illustration. In ...

Abstract

The present invention discloses a service access method and device. The method includes: when a load balancing device receives a DNS request message, it uses the domain name information carried in the DNS request message to query a DNS address table; if the DNS address If the domain name information is recorded in the table, the server identification corresponding to the domain name information is sent to the terminal device; when the service access message carrying the server identification is received, the service access message is sent to the corresponding server, and send the service response message from the corresponding server to the terminal device. In the embodiment of the present invention, it is possible to enable the load balancing device to determine the optimal ISP link, thereby improving user experience.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a service access method and equipment. Background technique [0002] Such as figure 1 As shown in the figure, it is a schematic diagram of a link load balancing network. When a terminal device (such as a PC) on an enterprise intranet accesses services of a server on the Internet through a domain name, such as accessing Sina mailbox services through email.sina.com.cn, the PC sends The DNS (Domain Name System, Domain Name System) request message is intercepted by the load balancing device, and according to the pre-configured strategy, it is sent from multiple ISPs (Internet Service Provider, Internet Service Provider, figure 1 Only one ISP link is selected in the two) links, assuming that ISP link 2 is selected, the load balancing device sends the DNS request message to DNS server 2 in the ISP2 network through ISP link 2, and DNS server 2 will Analyze the DNS reque...
