Paper Abstract

In the environment that a lot of control equipments are connected discretely to offer those equipments additional flexibility, the network is required to be high speed, high reliability, and real-time responsibility. IEEE 13941-3 is preferable as the underlying data transport technology to meet such requirements. IEEE 1394 is an interface that can support Plug and Play between the control equipments without a host device, and guarantee real-time stream and data transmission. Using the technology as a backbone network is suitable for control network due to its characteristics. However, in the current IEEE 1394 specification, there are some issues: band shortage when a lot of devices are connected and the reliability decrease in the communication when the network topology changes. By using the new technology, the bus bridge for IEEE 1394, some of the problems can be handled. Nevertheless, some issues still remain even if the bus bridge technology is applied. In this paper, to address these issues, we have proposed the message-type service discovery method. The message-type service discovery can achieve the efficiency of forwarding communication by transmitting service information of the equipment as a set of messages. The proposed method enables to transmit service information of the equipments at high speed. Then, we actually measured the time required for the service discovery of the proposed method and discussed about the basic characteristics.
