Abstract: The invention is to provide an STM-16 Network-Node Interface(NNI) which is capable of exactly checking whether a fault is generated on any station when the VC-4 AU received from a remotely located station has the fault, by checking the incoming data streams and communication with the remote node using the still unused values of APS bytes, thereby further enhancing the reliability thereof, which comprising duplicate physical layer processing blocks for processing a physical layer to provide a plurality of simplex ATM layers, and an ATM layer controller for controlling the processing condition of each of the ATM layers processed by the ATM layer processing means, to thereby processed information to the microprocessor; and ATM layer processing block for processing the ATM layers to a plurality of ATM cells.

Abstract: An STM-16 Network-Node Interface (NNI) is capable of checking whether a fault is generated on any station when the VC-4 AU received from a remotely located station has the fault, by checking the incoming data streams 17 and communication with the remote node using the still unused values of APS bytes. The interface comprises duplicate physical layer processing blocks 10 for processing a physical layer to provide a plurality of simplex ATM layers, an ATM layer controller 40 for controlling the processing condition of each of the ATM layers processed by the ATM layer processing means, a controlling microprocessor 15; and ATM layer processing block 20 for processing the ATM layers to a plurality of ATM cells.

Abstract: Disclosed herein is a resource allocation method for providing load balancing and fairness for a dual ring. The resource allocation method includes the step of determining whether a bandwidth allocation request message is received from one of other nodes. If the bandwidth allocation request message is received, it is determined whether one or more of two rings of the dual ring fulfill a request of the bandwidth allocation request message. If the rings fulfill the request, a path is allocated to one of the rings having a lower weighted cost. A resource allocation information notification message is provided to other nodes. If the rings cannot fulfill the request, the process ends.

Abstract: In a dual ring network, a resource allocation method includes the step of determining at a network node whether a bandwidth allocation request message is received from one of the other nodes. If the request is received, it is determined whether one or more of two rings of the dual ring fulfill the request. If the rings fulfill the request, a path is allocated to one of the rings having a lower weighted cost. A resource allocation information notification message is provided to the other nodes. If the rings cannot fulfill the request, the process ends. According to an alternative resource allocation method, each of the nodes are provided with a primary and secondary transit queue (PTQ and STQ) and the allowed data rate is adjusted in dependence upon congestion and the size of backlogged packets in the STQ. The dual ring network may be a Resilient Packet Ring (RPR), SONET, Fibre Distributed Data Interface (FDDI), token ring, or the like.

Abstract: PURPOSE: A human body communication system, medium access control bridge, bridge apparatus, and operation method thereof are provided to reinforce the stability of communication by reducing restrictions on a transmission distance between apparatuses which have two different transmission methods. CONSTITUTION: A data traffic manager receives packets from a first human body related network(S101). A connection establishment manager confirms a connection establishment state for the packet(S113). The connection establishment manager confirms the receiver address of the packet through the connection establishment state. In case the receiver address of the packet belongs to a second human body related network, the connection establishment manger transmits the packet to a second human body related network through a second communication protocol(S119,S121).
