Abstract
A node apparatus of such a ring communication network including buffers capable of improving a performance of the ring communication network and yet maintaining a global fairness in use of a ring communication network bandwidth among nodes, and a method for controlling the node apparatus. The node apparatus includes a receiver unit for receiving packets and slots from a ring, an ordering buffering unit for ordering the packets, a receiving queuing unit for temporarily storing messages of the packets to be sent to a host, a trunk buffering unit for temporarily storing packets to be transmitted to other nodes and then relaying the stored packets, a transmitting queuing unit for storing messages to be transmitted to the ring, and a transmitter unit for transmitting packets and messages in a medium access control manner. The control method includes the first step of checking about a destination node for a packet received to a node, the second step of processing the packet when the destination node corresponds to the packet-received node, the third step of processing the packet in a manner different from the second step when the destination node corresponds to a node other than the pack…
