Method and apparatus for transmitting data frame

우선순위가 높은 데이터 프레임을 우선적으로 전송하여 데이터 프레임의 전송 효율을 향상시키기 위한 데이터 프레임 전송방법 및 장치가 개시된다. 데이터 프레임 전송방법은 수신된 복수개의 데이터 프레임의 충돌 발생 여부를 판단하고, 판단결과 충돌이 발생한 데이터 프레임의 우선순위를 판단하며, 우선순위에 따른 백오프 타임을 산출하고, 산출된 백오프 타임에 따라 충돌이 발생된 데이터 프레임을 전송한다. 따라서, 데이터 프레임의 우선순위에 따라 백오프 타임을 다르게 설정하여, 상대적으로 우선순위가 높은 데이터 프레임의 백오프 타임을 짧게 하고, 상대적으로 우선순위가 낮은 데이터 프레임의 백오프 타임을 길게 하여, 우선순위가 높은 데이터 프레임을 우선적으로 전송할 수 있다. Disclosed are a data frame transmission method and apparatus for firstly transmitting a high priority data frame to improve transmission efficiency of the data frame. The data frame transmission method determines whether a collision of a plurality of received data frames has occurred, and as a result of the determination, determines a priority of a data frame in which collision has occurred, calculates a backoff time according to the priority, and calculates the backoff time based on the calculated backoff time. Therefore, a collision-causing data frame is transmitted. Therefore, by setting the backoff time differently according to the priority of the data frame, the backoff time of the relatively high priority data frame is shortened, and the backoff time of the relatively low priority data frame is long, Higher priority data frames can be transmitted first.

Method of determining request transmission priority subject to request channel and transmitting request subject to such request transmission priority in application of fieldbus communication framework

A method of determining request transmission priority subject to request channel and transmitting request subject to such request transmission priority in application of Fieldbus communication framework in which the communication device determines whether the request channel from which the received requests came have the priority right and whether there is any logical operation condition established, and then the communication device transmits the received external requests to the connected slave device as an ordinary request or priority request, preventing the slave device from receiving an important external request sent by the main control end or manager at a late time.

Method for transmitting data via a serial communication bus, bus interface, and computer program

An extension of the existing CAN FD data transmission protocol. The extension enables the use of the IPv6 protocol for the CAN bus. The CAN FD protocol is further developed in an incompatible way. One modification measure relates to the lengthening of the Data Field, which is positioned in the transmission frame after an Arbitration Field. An arbitrary number of bytes can be entered in the extended Data Field within a specified upper limit. Since the Data Field is transmitted at a higher bit rate field than the Arbitration Field, the data throughput is increased dramatically.

Network system

Improved random access channel protocol

The present invention provides an improved random access channel protocol, wherein different user elements may be associated with different priority levels. Based on relative priority, the user elements may have different probabilities for deciding when to retransmit a previously transmitted packet upon receiving information from an access point indicating that the packet needs to be retransmitted. A buffer is provided for storing a packet to transmit, and the buffer is associated with a stack counter, which is incremented or decremented to or from a nominal value to determine when to transmit or retransmit the packet stored in the buffer. Based on the relative priority, feedback information from the access point may cause the stack counter for a packet needing to be retransmitted to stay at the nominal value, wherein retransmission will occur at the next available time slot, or it may increase the stack counter by one or more levels.
