摘要： PROBLEM TO BE SOLVED: To provide a dual port Ethernet communication device which allows data received via any one communication port to be bypassed to the other communication port. SOLUTION: Since this Ethernet communication device directly performs such a bypass operation, the communication data is transmitted to a mating terminal even if the terminal equipped with the Ethernet communication device can not operate normally due to a cause such as a failure. In particular, when the Ethernet communication device is used in each terminal forming a closed loop in a normally-closed loop system of a power system, the communication on the closed loop is maintained, and thereby the adjacent terminal promptly performs a backup interrupt function even if a trouble happens in a specific terminal forming the closed loop.

摘要： PROBLEM TO BE SOLVED: To provide a hardware protocol stack capable of processing a protocol directly declared by a user at a high speed by developing an automatic interpretation function fixed in each different type of a protocol.SOLUTION: A hardware protocol stack (20) relating to this invention stores header information of an analysis target protocol in a register part (21), and compares whether the information recorded in a header of an inputted frame and the header information stored in the register part are mutually matched to thereby extract data.
摘要翻译：要解决的问题：提供一种能够通过开发固定在每种不同类型的协议中的自动解释功能来高速处理由用户直接声明的协议的硬件协议栈。解决方案：一种硬件协议栈（20），涉及本发明将分析目标协议的报头信息存储在寄存器部分（21）中，并且比较记录在输入帧的报头中的信息和存储在寄存器部分中的报头信息是否相互匹配，从而提取数据。

摘要： PROBLEM TO BE SOLVED: To provide a switching device of dual-port Ethernet(R) capable of solving a conflict due to a dual port in an Ethernet(R) system having the dual-port. SOLUTION: The switching device of the dual-port Ethernet(R) includes: a media controller for controlling transmission and reception of a frame through Ethernet(R); a transceiver buffer for transmitting and receiving a data frame to and from an upper layer device, the transceiver buffer being connected to the upper layer device through certain buses; a data distributor for receiving a frame from the media controller and transferring the frame to at least one of the transceiver buffer and a switch buffer; the switch buffer for receiving a reception frame from the data distributor and deciding whether to transmit the frame to a data selector of another media controller; and the data selector for receiving a frame from each of the transceiver buffer and the switch buffer and transmitting the frame to the media controller, the data selector selecting any one of the data frame inputted from the transceiver buffer and the data frame inputted from the switch buffer by determining a priority of the frame and transferring the selected frame to the media controller.
