摘要： An overlay network traffic detection system deploys traffic measurement units at multiple points on a network, creates profiles of the network traffic measured at each point, and then compiles the traffic profiles obtained at different points. The compiled profile of outbound traffic originating at a node is compared with the compiled profile of inbound traffic addressed to the same node. A strong correlation between the two profiles indicates that the node is relaying overlay network traffic. Further information can be gained by profile screening, by active interference in the traffic flow, by launching known information into the network at known times and observing its effect on the traffic profiles, and by observing keyword distributions in non-encrypted traffic.

摘要： An optical communication network for sheltering traffic by a simple processing when a communication path is dynamically changed. In the optical communication network system according to the present invention, the sufficiency of a resource for setting a new communication path is confirmed, and if the resource is insufficient, a communication path to be cancelled is selected from current communication paths of which priority is lower than the new communication path, so as to secure the resource, and the IP traffic of the current communication path to be cancelled is sheltered to another communication path, the current communication path is cancelled after this sheltering completes, and then the new communication path is set. When the current communication path is cancelled, the traffic of this current communication path is sheltered to another communication path before cancellation, so the loss of traffic can be prevented merely by a simple processing.

摘要： A method for setting a cut-through optical path in an optical network system is proposed. At first, a destination side edge node device which confirmed,the transfer of a packet to a terminal accommodated by the present node device or to an access system network notifies the open resource information of the present node device to a transmission side edge node device. Then the transmission side edge node device determines the optimum allocation of an optical path to be set on the transfer route based on the open resource information notified by the destination side edge node device and the core node device. Then, according to the allocation optical path determined in the previous step, the transmission side edge node device, the core node device, and the destination side edge node device set the optical path which omits the packet transfer processing (layer 2 and layer 3 processing) in transit nodes.

摘要： In subscriber units 0 to (N−1), a subscriber unit to be allocated to a bandwidth is defined as a subscriber unit K, where K is an integer from 0 to (N−1) inclusive. In a bandwidth allocating method, a free bandwidth in a communication channel ch(K−1) not used by the subscriber unit (K−1) is found, and a bandwidth requested by the subscriber unit K is allocated to the free bandwidth in the communication channel ch(K−1). A free bandwidth in the communication channel chK is found on the basis of a residual bandwidth requested by the subscriber unit K not allocated to the bandwidth in the communication channel ch(K−1), and the residual bandwidth requested by the subscriber unit K is allocated to the found free bandwidth in the communication channel chK. The operation is repeated for the subscriber units 0 to (K−1) and (K+1) to (N−1).

摘要： A dynamic bandwidth allocation method that can allocate bandwidth dynamically so as to guarantee communication in a minimum guaranteed bandwidth from each subscriber device and enable communication within a maximum communicable bandwidth from each subscriber device. A subscriber device asks a control functional unit at least once for bandwidth in which to transmit packets to switching office equipment, and the control function unit allows transmission in a minimum guaranteed bandwidth determined in advance for every subscriber device and generates control data for allocating to each subscriber device the bandwidth that it may use so as to maximize the bandwidth that can be used for packet transmission within the maximum transmittable bandwidth while maintaining fairness. The control functional unit transmits the control data to each subscriber device, thereby notifying each subscriber device of the bandwidth it can use, and each subscriber device transmits packets in the specified bandwidth.

摘要： A network system comprises nodes, a network management system and a plurality of user terminals. Each of the nodes established on the network system comprises an optical cross connect and a packet switch. The packet switch accommodates a plurality of terminals. Each of the nodes monitors traffic transferring in the packet switch thereof. Alternatively, each of the nodes monitors start and end of an application of each of the terminals included therein. Alternatively, each of the nodes measures delay time between the nodes. Then, each of the nodes reports the packet flow, the start and the end of the application, or the delay time between nodes to the network management system. The network management system establishes an optical path between each of the nodes based on the packet flow, the start and the end of the application, or the delay time between nodes monitored by each of the nodes.
