Data stream optimization device and method for realizing multi-ISP (internet service provider) access in local area network

Abstract

The invention relates to a data stream optimization device for realizing the multi-ISP (internet service provider) access in a local area network. The data stream optimization device comprises a flow acquisition module, a flow analysis module, a network detection module, a detection result analysis module and a configuration management module which are connected sequentially, wherein the flow acquisition module is respectively connected with a DNS (domain name server) arranged outside the data stream optimization device and a network interface of a routing device, and the configuration management module is respectively connected with the DNS and a configuration management interface of the routing device. The invention also relates to a data stream optimization method for realizing the multi-ISP (internet service provider) access in a local area network, which comprises the following steps: firstly, acquiring network data streams, and judging whether the network data streams are required to be optimized; then, detecting the network data streams required to be optimized, and analyzing and determining an optimal ISP access port according to the obtained detection results; and finally, configuring the DNS and the routing device. By using the device and method provided by the invention, an ISP access port with optimal connection performance can be selected, and the automatic optimization of data streams can be realized.

Description

technical field [0001] The present invention relates to the field of network technology, in particular to the technical field of multi-operator access in a local area network, in particular to a data flow optimization device and method for realizing multi-operator access in a local area network. Background technique [0002] At present, in order to speed up access to the Internet for local area networks (such as enterprises, institutions, data centers, etc.) that need to access the Internet, interfaces of multiple operators (ISPs) are often used. and other operators’ WAN, its multi-operator access structure is as follows: figure 1 shown. When multiple operators are connected, there are two main types of applications: one type is mainly for accessing WAN resources (for example, enterprises and institutions), and this type of application is used in figure 1 Indicated by a dotted line; the other type mainly provides services for the wide area network (for example, data center...

Problems solved by technology

Most of the routing configuration strategies come from the introduction of existing technologies related to the Internet and the accumulation of LAN’s own operation and maintenance experience. Such routing configuration strategies cannot achieve overall real-time optimization for the connection status of the local area network, and are very time-consuming and laborious.

In response to this problem, there are currently some dedicated multi-ISP access optimization devices on the market. These optimization devices either cannot provide an integrated solution for the above two types of access at the same time; Other access means that the overall safe and stable operation of the LAN introduces a potential point of failure, which has an adverse effect on the stable operation of the LAN
