Abstract:
1. A device requiring address allocation, the device comprising: a storage unit configured to store address allocation flag information and address information; a contention signal output unit connected to the storage unit, and configured to output an address-contention signal to the device after a random duration in response to receiving a contention-start signal and when the address allocation flag information indicates that no address information is allocated; and an address configuration unit configured to: (i) determine whether pre-allocated address information is available in response to the contention signal output unit outputting the address-contention signal by determining whether other devices requiring address allocation with address allocation flag information indicating that no address information is allocated are already outputting address-contention signals, (ii) write the pre-allocated address information to the storage unit when the pre-allocated address information is available, and (iii) modify the address allocation flag information to indicate that address information is already allocated.
