초록 ▼

A frame relay system relays a received frame having a destination address and a frame TTL indicating a term of life of the received frame. The frame relay system includes a routing table having entries, each of the entries indicating a relationship between a destination address and a control information item, a retrieving unit for retrieving the routing table based on a destination address included in the received frame, and a frame control unit for carrying out a decrement calculation of the frame TTL of the received frame when a period of time has elapsed from a time at which an entry hit in retrieving of the routing table by the retrieving unit was formed or updated is not equal to or greater than a predetermined value and for not carrying out the decrement calculation of the frame TTL when the period of time period is equal or greater than the predetermined value.
