This paper presents a new kind of Real-time Control Protocol to solve the problem of nondeterministic network traffics on Ethernet, expatiate to the basic theory of the protocol, prove that this protocol can help the Ethernet implement transmit real-time data by experiment and implement the protocol Stack in RTLinux OS

‘Ethernet over WDM’ is very promising as a next-generation network technology. After some prospective Ethernet-based services are introduced, a novel WDM-based wide-area access network, combined with a regional transport network, is introduced. This network enables the efficient deployment of such services. We show a detailed system configuration of the network and OAM information channels that are effective for it. We then present its management information model in reference to the architectural transport model. This model will be useful in building network management systems.

Based on the standard of EPON and the research results, this paper introduces the mechanism of multi-point control protocol and compares the Statistical bandwidth allocation (SBA) and Dynamic bandwidth allocation (DBA), according these, this paper proposes a new scheduling algorithm to support the quality of services (QoS) in EPON. Here, static bandwidth allocation for guaranteed bandwidth service and dynamic bandwidth allocation for on-demand, dynamic traffic services.

This paper studied an integrated protection device for the coal mining motor to monitor and protect the motor in real time when it experiences malfunction in cases such as overload, unbalanced current, blockage and starting timeout. The device utilizes the Cortex-M7, a core of the KV5x series chip, to ensure sampling efficiency and smooth operation speed. Due to the design and integration of hardware and software components, this device has high efficiency and stability, and strong anti-jamming ability. The experimental results demonstrate that the system has improved precision and stability.
