Abstract: The present invention is to notify a user of whether content streaming service will be provided well or not by obtaining information for transfer of a content to be provided from outside before traffic of the content starts to be transferred. In a method according to the present invention, a CP (Control Point) or a gateway at a home network obtains requests an external server to provide information for transfer of a content stored in the external server, a TD (Traffic Descriptor) is constructed based on the provided information for transfer, and a QoS (Quality of Service) manager invokes an action requesting permission of traffic requiring a bandwidth specified by the TD to devices to be involved in traffic transferring of the content.

Abstract: The present invention relates to a method for managing traffic transfer services on a network. One of the present methods determines priority reference ensuring to retrieve bandwidth greater than necessary bandwidth, if current available bandwidth is not sufficient for a new connection, and selected selects a combination of in-service connections whose priority is not higher than the determined priority reference such that the selected combination is able to return the necessary bandwidth and the number of connections in the selected combination is smallest as well. The connections pertaining to the selected combination are pre-empted to permit access of the new connection to the network.
