Adaptive traffic management system and method based on device-media context information matching in home network

摘要

Disclosed is an adaptive traffic management system and method based on terminal-media context information matching in a home network. The system recognizes a terminal existing in a home network using a service search technology and collects context information of each terminal. The home gateway limits the quality of transmitted content (bitrate of video data) by comparing the collected situation information with the media information stored by the content server, and classifies the traffic of each terminal to control priority-based packet scheduling and traffic Gateway; An HTTP server that stores contents; And an HTTP client that receives and plays the content requested by the HTTP server through the home gateway. In addition, the home gateway classifies each traffic being transmitted into classes using service and payload information, and adaptively allocates bandwidth to each terminal according to the characteristics of the classified class and schedules packets to be transmitted based on priority. It provides the optimal quality of service (QoS) to the user terminal.
