Abstract: PROBLEM TO BE SOLVED: To reduce reception error of response data and an overflow rate by setting a delay value inside request data and transmitting it on a request data transmission side and calculating the delay time by the delay value and a random number value, performing delay for the delay time and then transmitting the response data from the reception side. SOLUTION: In the case that a communication equipment A1 performs the multi-cast or broadcast transmission of the request data to the communication equipments B2-the communication equipment E5 connected on the same transmission communication path 6, the maximum delay time value of the response data is stored inside the request data and transmitted. In an application processing part 30 which receives it through a communication control part 10 and a protocol processing part 20, a data reception processing part 31 takes out the delay value D inside the data and takes out a random number R from a random number generation part and the delay time T is calculated in a delay time computing part 34. It is defined that T=R%D*t (meaning that the residual value of R/D is stored in T) and (t) is unit time. A delay part 44 commands response transmission after the delay time.
