Abstract
In a LAN relaying apparatus, a reception side control circuit receives a reception side write pointer from a reception side write control circuit and a reception side read pointer from a reception side read control circuit, and determines a reception side pointer difference between the side reception side write pointer and the reception side read pointer. Then, the control circuit controls the reception side read control circuit to start the second side read operation when the reception side pointer difference is equal to a reception side first threshold held therein. Subsequently, the reception side control circuit controls the reception side write control circuit and the reception side read control circuit such that the first side write operation or the second side read operation is carried out based on the reception side pointer difference, when the reception side pointer difference is not equal to the reception side first threshold after the start of the second side read operation.
