Embodiment Construction

[0033] According to an exemplary embodiment of the present invention, a network control device collects network status information from edge devices of the network. Based on the network status, the network control device directs the service sent from the user side to a specific path or a specific receiving end in the network. Thereby, according to the network state, user traffic can be flexibly transmitted through the network, and the use of the frequency band of the WAN can be maximized. In addition, although the edge devices of the network are controlled, it is not necessary to control all the communication devices on the route, thereby greatly reducing the switching control time. Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

[0034] 1. System configuration

[0035] Such as figure 1 As shown, the network system of the present invention includes a wide area network (WAN) 10 and a plurality of use...

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...
