摘要： A system and method for exactly estimating a volume of traffic is provided when packets are transferred within the network. The system and method receive data packets from clients through a plurality of router-for-clients, and creating a flow information packet for estimating information about a flow, transfer the data packets and the created flow information packet to the destination router-for-client via a router-for-relay, calculate information about the traffic of a flow at the destination router-for-client through the flow information packets transferred from the router-for-clients, and estimate a volume of the traffic. Thus, the system and method can estimate the volume of the traffic on the network with respect to the aggregated flow defined by the router pair connected to the terminal or the external network when the traffic is actually introduced into the network, instead of the flows of each terminal and each destination.

摘要： A hybrid channel assignment method comprising the steps of negotiating among routers to select one router to act as a central server; collecting, at the selected router, information on an entire network transmitted from the other routers, and assigning channels based upon the information on the entire network; and reassigning channels of respective routers based upon dynamically-changing traffic characteristics. The hybrid channel assignment method can assign channels using both centralized processing and distributed processing in order to ensure optimally correct channel assignment consistent with present traffic characteristics. This as a result can prevent network resources from being wasted and also increase network capacity, thereby optimizing effective use of the network resources.

摘要： A method is provided for registering a mobile router in an Internet Protocol version 6 over Low power Wireless Personal Area Network (6LoWPAN) network. The mobile router detects movement into a wireless network through the reception of a beacon message, and sends a Router Solicitation (RS) message requesting registration in the wireless network to a gateway. The gateway acquires an address of the mobile router from the RS message, stores the acquired address, assigns a new address to be used in the wireless network to the mobile router, and sends a Router Advertisement (RA) message with assigned address information and gateway address information, to the mobile router. The mobile router acquires the assigned address information and the gateway address information from the RA message.

摘要： A method is provided for supporting mobility of a Mobile Node (MN) in a multi-hop Internet Protocol (IP) network, in which an MN that has moved from a source Personal Area Network (PAN) to a target PAN, sends a Router Solicitation (RS) message with an option for requesting its profile to a gateway of the target PAN, and receives a Router Advertisement (RA) message from the gateway in response to the RS message. The RA message includes a home prefix of the MN as the requested profile. The method supports mobility of MNs, enables unicast communication, and facilitates efficient use of the network.

摘要： In a queue management method and apparatus in a network processor, enqueue completed and de-queue completed messages are transmitted to a scheduler when a queue manager performs enqueuing and de-queuing operations in the network processor, so that the queue processing time is synchronized between the queue manager and the scheduler. The queue manager in the network processor performs the de-queuing operation, includes the packet size information extracted from de-queued packet identification information in the de-queue completed message, and transmits it to the scheduler, so that the scheduler calculates the correct quantum of the port and queue.

摘要： In a buffer switch and scheduling method thereof, conflict sensing and random selection logic configuration are not required. The buffer switch comprises: input buffer units for converting serial data inputted from respective input ports to parallel data; shift and comparison units for comparing currently stored data to parallel data aligned by the input buffer units, for determining paths to output the data depending on data validity, and for calculating a gating time needed to forward the data; output buffer units for outputting the data received via the input ports at the same speed as the speed at reception; a switching unit for gating paths between the shift and comparison units and the output buffer units; and a control unit for establishing the paths by enabling the input buffer units and the output buffer units for the gating time of relevant buffers depending on the establishment paths and the gating time from the shift and comparison unit.
