Then the environmental conditions, network requirements and critical technologies for the development of multimedia communication are depicted. After that, the present status and development trends of foreign multimedia communication are introduced. Finally, several points that should be paid attention to in the development of multimedia communication in China are proposed.
IP addresses of these computers behind NAT is unseen from Internet, and computers in Internet can't access these computers behind NAT actively. But the P2P network requires that any computer can exchange information directly, thus P2P applications must solve the problem of bidirectional communication across NAT.
This paper introduces the conceptions, protocol model and related standards of fieldbus, analyses and summarizes network demands for industrial control system and functon demands for electrical control system. An advanced scheme for integrated industrial control system and electrical control system are pointed out.
Our results suggest that the contraction of muscle fibres limits the severity of connective tissue damage, and that muscle damage accompanied by disruption of the muscle connective tissue network requires a relatively longer recovery time.
The network requires the proprioceptively mediated actual state variables (here angular velocity and position) of each arm segment.
Thus, computing such a function at one node of a distributed network requires this node to communicate with every other node in the network.
The complex nature of the process-network requires greater emphasis on interdisciplinary cooperation and alternative methods to the linear statistical model.
To determine maximum-likelihood magnitudes for a given seismological network requires estimates of the detection thresholds of short-period P for the individual stations.
