Method and device for controlling network

Abstract

The present invention provides a method and a device for controlling a network that enable efficient and flexible transmission of user traffic through the network. Network control devices (100) collect internal network states of a network (WAN (10)) through edge devices (300), and traffic transmitted from user sites (20) is directed to a specific route or a specific receiving end within the network through the edge devices on the basis of the network states.

Description

[0001] This application is based on and claims priority from Japanese Patent Application No. 2012-092798 filed on April 16, 2012, the entire disclosure of which is incorporated herein by reference in its entirety. technical field [0002] The invention relates to network control technology, in particular to a network control method and equipment for controlling user services. Background technique [0003] In this technical field, users who receive communication services via a wide area network (WAN) generally aggregate communication traffic volumes of various application software used by the users themselves, and conclude a contract with a communication service provider on the use of a frequency band based on the aggregation value. [0004] For example, a company having a plurality of bases estimates the amount of communication traffic between the respective bases, and uses a dedicated line service or a virtual private network (VPN) service of a communication service provider...
