  • Patent number: 7324530
    Abstract: Provided is a routing method for determining a destination in a computer network having multiple interconnected nodes, the method for measuring packet delays among remotely located gateways and processing routing in application layers of the gateways using the packet delays. The routing method based on packet delay includes the steps of setting a re-routing interval and measuring one-way delays among gateways, exchanging the measured delays among the respective gateways and forming delay time tables, calculating an average one-way delay during the re-routing interval, and if a packet is received, applying the calculated average one-way delay to a predetermined algorithm and determining a path from a source gateway to a destination gateway, the path having the minimum delay. Therefore, an improved routing performance can be achieved in real time transmitting a packet by determining the minimum delay path to a destination by measuring packet delays among remotely located nodes in application layers thereof.

  • Patent number: 7263204
    Abstract: A blind watermarking method by grouping codewords for VQ-quantized images is disclosed. Especially there is provided a watermark insertion method in which a codebook is divided into three groups satisfying specific standards and a codeword is allocated based on the group to which the corresponding codeword belongs to insert watermark information, and a watermark extraction method for extracting the watermark inserted by the watermark insertion method. According to the present invention, watermark information can be uniformly inserted into an input vector space and the original image is not needed for extracting the watermark information.
