Provided is a method in which a management server provides wireless LAN security policy by participating in multiple APs. The method includes a step of receiving terminal information of a terminal, which is acquired in a process of scanning broadcasting information of multiple APs, from each of the multiple APs, a step of issuing and storing a token for opening a wireless LAN data channel to each of the multiple APs on the basis of reception time points of the terminal information, a step of receiving a token request for opening a wireless LAN data channel to an AP to be accessed, selected by a terminal among the multiple APs, and a step of distributing, to the terminal, a token of the AP to be accessed corresponding to the token request.

Provided is a matching system including a policy and rule processing unit configured to extract SC units for each application service required, combine the SC units, configure a transaction unit, and determine an amount to be charged for a transaction according to a charging rule; a matching processing unit configured to match the extracted SC units to NC units; and an NC combination processing unit configured to combine the NC units used for the matching and deliver the combination of the NC units and detailed operating conditions to the networking management system.

Network operation system and method

A method of controlling congestion of network equipment that connects networks with each other, includes determining a type of congestion based on a location of the network equipment; and identifying a network connection section having a strong possibility of occurrence of congestion based on the type of congestion, and setting a critical congestion bandwidth that is used to determine the occurrence of congestion. Further, the method includes identifying users required for equal distribution of traffic upon occurrence of congestion based on the critical congestion bandwidth; and equally distributing traffic to the identified users based on the critical congestion bandwidth, and then dropping an excess of arriving traffic over the equally distributed traffic, thereby performing avoidance of the congestion.

Method and apparatus for controlling congestion of network equipment

A method and an apparatus for fairly allocating resources to network users are provided. The method for fair resource allocation to network users allows the resource allocation apparatus to collect flow information between a user terminal and a service server and aggregates the flow information based on at least one of a user terminal address, a service server address, a user terminal, a service server address, and a service. The allocation resource of the user is controlled to the predetermined recommended bandwidth by using the ratio of the aggregated flow information.
