    摘要： Provided is a routing method capable of expanding a conventional tree routing to perform the efficient and safe key management in a sensor network environment that requires the symmetric key based key management. Each sensor node transmits a Route Reverse message to a sink node to set a reverse tree routing path. Therefore, it is possible to provide efficient and safe key management mechanism and communication environment by providing a bidirectional communication between a sink node and sensor nodes through an expanded tree routing such that a user is provided with a safe sensor network.

    摘要： A distributed resources sharing method using weighting factors of sub-domains in an optical network includes connecting working paths to an optical network according to a request of a subscriber, and calculating weighting factors for measurement of concentration of the sub-domains including the working paths by using information on connected working paths. The method also includes 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. With this method, 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 by using a weight factor, the shared resources can be distributed, thereby maximizing efficiency of the resources.

    摘要： A multi protocol label switching (MPLS) apparatus and method are provided. The first forwarding method is a method of forwarding the packet based on the destination address of the packet, and the second forwarding method is a method of forwarding the packet based on a label. When an error has occurred at an LSP between a node and another node, information indicating that an error has occurred at the LSP is recorded in the forwarding table, and the first or second forwarding method is selected based on what is recorded in an error information field of the forwarding data. Accordingly, it is possible to considerably reduce node/network loads and guarantee the continuity of services provided in the MPLS network even when an error has occurred at an LSP in the MPLS network.

    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.
