Method and device for realizing business connection

Abstract

The invention provides a method for realizing business connection. The method is applied to network gateways. Wide area network ports of the network gateways are respectively connected with differentservice providers. The method comprises the steps of accessing a resource management server when it is detected that network delay of the WAN (Wide Area Network) ports connected with a first service provider is greater than a set threshold, and confirming an idle network gateway of which WAN port connected with the first service provider is in an idle state; sending bandwidth rent request information to the idle network gateway; and sending a to-be-sent business request data packet to the idle network gateway through the WAN port connected with a second service provider when bandwidth rent acknowledgment information sent by the idle network gateway is received, thereby enabling the idle network gateway to send the to-be-sent business request data packet to a target server through the WAN port connected with the first service provider. According to the technical scheme, the regional load balancing of the network gateways is realized, the business load of congesting network gateways is reduced, and user business requirements are guaranteed.

Description

Technical field [0001] The present invention relates to the technical field of computer networks, in particular to a method and device for realizing service connection. Background technique [0002] In a home network, a router is generally used as a home network gateway, and is connected to an Internet Service Provider (ISP) network through a wide area network (WAN) port of the router to realize a business connection between a user terminal and an external network. When a user initiates multiple parallel services, due to the limitation of the export bandwidth, the network gateway, that is, the WAN port of the router is congested, which affects the user's service connection. [0003] In order to improve the service access capability of the network gateway, a dual WAN port router is proposed in the industry, and the two WAN ports of the router are connected to different ISP networks. When a user initiates a service connection through the above-mentioned dual WAN port router, the use...

AI Technical Summary

Problems solved by technology

[0004] For a single WAN port of a router, although the traffic it undertakes becomes less when the traffic initiated by the user remains unchanged, due to reasons such as the ISP infrastructure, when the traffic initiated by the user is relatively large, the bandwidth of the inter-network link may decrease. It still cannot meet the user's business needs. At this time, the business response time will still be long, or the business cannot be connected.
