Embodiment Construction

[0055] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0056] Apply the intelligent route selection method for computer network links of the present invention to the communication between the internal network and the external network (Internet) of a unit that rents both the telecommunication link and the Netcom link, to realize the intelligent routing of message sending route. The unit's network equipment is deployed as figure 1 As shown, the intelligent routing device 2 is set at the internal network exit and the external network interface, and all external network lines are connected to the intelligent routing device 2 . By registering a callback function at the message forwarding hook point of the intelligent route selection device 2, the messages for accessing the external network can be intercepted, and then routed to the selected network interface to realize intelligent route selec...

Abstract

The invention discloses an intelligent routing method for computer network links, comprising the following steps of: intercepting a message for requesting outside access by a smart link selector, and if the message is a new assess request message, searching a main Hash table according to the target address of the massage; if the main Hash table includes the target address, marking a link corresponding to the target address and transmitting data according to the information of a link interface corresponding to the mark; if the Hash table does not include the target address, putting the target address into a pool for addresses to be found by the smart link selector, searching the pool for addresses to be found by a search processor, firstly performing static routing to rapidly obtain a primary routing result, and providing the primary routing result to the smart link selector for use; and then amending the static routing result according to dynamic routing, updating the main Hash table, marling the link according to the routing result and transmitting the data. The routing method for computer network links has the advantages of high dispatching speed, high accuracy and low consumption for system resources.

Description

technical field [0001] The invention relates to the field of computer networks, in particular to a method for selecting routes of computer network links. Background technique [0002] With the rapid development of the Internet, enterprises, schools, government departments, etc. have an increasing demand for the Internet. China's major ISPs (Internet Service Providers, Internet Service Providers) include: China Telecom, China Netcom, and Railcom. Objectively speaking, the interconnection between ISPs has problems such as slow speed and easy disconnection. For example: Telecom users access Netcom's server, or Netcom users access Telecom's server, the connection is often slow, dropped, or even the service cannot be accessed, which affects the service quality and user experience. This phenomenon is common across the country, so that many websites can only take a step back and list different entrance links for different ISPs used by users on the website, allowing users to choos...
