Abstract: Disclosed herein is a quantum dot phosphor for light emitting diodes, which includes quantum dots and a solid substrate on which the quantum dots are supported. Also, a method of preparing the quantum dot phosphor is provided. Since the quantum dot phosphor of the current invention is composed of the quantum dots supported on the solid substrate, the quantum dots do not aggregate when dispensing a paste obtained by mixing the quantum dots with a paste resin for use in packaging of a light emitting diode. Thereby, a light emitting diode able to maintain excellent light emitting efficiency can be manufactured.

Abstract: Provided is a network resource provisioning method for bandwidth guarantee per flow in a differentiated service Internet in which bandwidth needed for each flow is individually requested. The method comprises setting an optimum path between a source node and a destination node based on a request for traffic for a specific period of time; performing static provisioning in which bandwidth is allocated to the optimum path according to a service class thereof; determining whether all of the bandwidth allocated to the optimum path by performing static provisioning are used up, and accepting connection admission according to the determination result; and when connection admission is not accepted, performing dynamic provisioning in which additional bandwidth is allocated to the optimum path based on a request for traffic from a new incoming flow. Accordingly, it is possible to efficiently provide a quality-guaranteed service by accepting a request for bandwidth per flow.

Abstract: In the adaptive connection admission control method of the present invention, a corresponding ingress edge node performs connection admission control for a new connection within the amount of bandwidth initially allocated to each of paths between the ingress and egress edge nodes. The amount of remaining bandwidth allocated to a specific path Pr is compared with an amount of bandwidth required for a call requesting new connection setup input to the corresponding ingress edge node. The amount of additional bandwidth to be requested from the bandwidth broker is predicted when the amount of the remaining bandwidth does not satisfy the amount of bandwidth required for the connection setup requesting call. The ingress edge node requests additional bandwidth from the bandwidth broker on the basis of the predicted amount of the additional bandwidth, changing bandwidth information of the corresponding path Pr, and performing connection admission control.
