A Load Balancing-Supported ID assignment method is the foundation to implement and maintain DHT overlays
realized constant degree DHTs usually use simple pure centralized or distributed ID management strategies
which cannot resolve the contradiction between cost of maintaining topologies' information and topologies' balance.Analyzing the universal tree structures in the topologies
an ID Assignment method RFIDAM based on the internal structure Routing Forest is proposed
which regularly aggregates local balancing information to guide new nodes' joining for overall balance.The experimental results show
with low maintenance and routing message overhead
the system's loading balance is efficiently ensured with the length of IDs differ by at most 2.
