    摘要: In a token bus system a node with the token can transmit on the bus a packet (90) that contains two destination addresses. One address specifies the node that should receive the data component (payload) of the transmitted packet. The other address specifies the node that should receive the token. The network protocol specifies that a node with the token must immediately transmit a packet (80) containing just the token or a packet (90) with token and data if it has data to send. When no data is being passed from one node to another on the network, the token may be passed from one node to the next in order. Each node will pass the token to the next highest node number. If a node has the token has some data for sending it transmits a packet with the token for the next node and data for any of the nodes. The bus system requires every node to receive all packets and process them to determine whether the token or the data (or both) is destined for that node.

    摘要: A communication circuit comprises a first communication section having a first transmitting section and a first receiving section, a second communication section having a second transmitting section and a second receiving section, a communication control section controlling communication at the first communication section and the second communication section, receiving processing section performing receiving process based on received communication data, wherein the first communication section and the second communication section distinguishes predetermined communication data, and in case either the first communication section or the second communication section receives the predetermined communication data alternatively, the communication control section controls to input the communication data received by the communication sections receiving the predetermined communication data into the receiving processing section, and to input the communication data into other communication sections so as to input communication data received by other communication sections into the transmitting section of the communication sections receiving the predetermined communication data without inputting it into the receiving processing section.

    摘要: The present invention is directed to a system, method, computer program in a node within a network comprising a transport layer protocol providing end to end data transfer, for multicasting datagrams on a virtual ring, each node on the virtual ring being logically connected according to the network transport layer protocol to two and only two neighbor nodes through virtual connections, an upstream neighbor node and a downstream neighbor node. The method comprises the steps of: • sending a virtual ring datagram to the downstream neighbor node on the virtual ring; said virtual ring datagram comprising a virtual ring identifier, means for identifying the node originator of the virtual ring datagram, and data; receiving a token, identifying the virtual ring and forwarding the token to the downstream neighbor node on the identified virtual ring; if the received datagram is a virtual ring datagram: identifying the virtual ring and checking the node originator of the received virtual ring datagram; if the received virtual ring datagram has not been locally originated: • processing data comprised in said virtual ring datagram; • forwarding said virtual ring datagram to the downstream neighbor node on the identified virtual ring; if the received virtual ring datagram has been locally originated: removing the virtual ring datagram from the virtual ring.
