摘要： A distributed resources sharing method using weighted sub-domain table of sub-domains in a GMPLS optical network is provided. The distributed resources sharing method includes; connecting working paths to an optical network according to a request of a subscriber; calculating a weighting factor for measurement of concentration of the sub-domains including the working paths by using information on connected working paths and information on backup paths; setting up the backup paths by using the weighting factors; and allocating resources in response to connection request at the time of setting up the backup path and sharing the allocated resources. Accordingly, it is possible to prevent a waste of idle resources caused from concentration of allocated resources. In addition, since the information of the idle resources in the network can be sensed at the time of selecting the backup paths for the previously allocated working paths by using a weight factor, the shared resources can be distributed, so that it is possible to maximize efficiency of the resources.

摘要： A high-speed content inspection apparatus for minimizing system overhead is provided. The high-speed content inspection apparatus extracts content in unit of sub-pattern by inspecting a payload of a packet in units of sub-pattern, and extract target content by inspecting a correlation between the extracted sub-patterns. If a sub-pattern present at the end of a payload is smaller than a predetermined unit of a sub-pattern, position information of the sub-pattern at the end of the payload is rolled back and the correlation is inspected. Accordingly, without having to add another hardware or high-performance hardware, target content can be efficiently detected in real time.
