摘要:
Disclosed is a network bandwidth distribution device which includes an information collector which collects information associated with a connection environment; a controller which judges a state of a connection environment according to the collected information and collects information of each user to judge whether an occupied bandwidth of each user is exceeded; and a bandwidth allotter which limits an occupied bandwidth of each user based on the judged state of a connection environment and whether an occupied bandwidth of each user is exceeded.

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.

摘要:
A method of binding a network-based service flow is provided. The method binds a network-based service flow through notification of a terminal by allowing the terminal to notify a mobile access gateway (MAG) of binding information of a desired service flow at a specific moment by allowing intervention of the terminal, and allowing the MAG to again notify a local mobility anchor (LMA) of corresponding service flow binding information.

A touch device is provided that allows users to easily select text in an Electronic Book (e-book), based on a touch interaction. A method is also provided that operates an e-book function in the touch device which includes displaying e-book content, receiving an anchor interaction at a location in text of the e-book content, displaying a number of candidate anchors, based on the location where the anchor interaction is input, determining two selected candidate anchors as definite anchors, and forming a block of text in the definite anchors.
摘要:
Disclosed are a method and system for distributed denial of service (DDoS) attack detection and traffic mitigation using flow statistics. The method for DDoS attack detection and traffic mitigation using flow statistics includes: collecting first statistics for each flow based on flow information generated by traffic flow of a network connection device; and grouping the first statistics for each flow on a per-flow basis and processing the same into second statistics containing at least one of the number of bytes, the number of packets, and the number of flows per unit time.
