... successor(k), which is the node whose identifier is equal to or follows the identifier of k. If there are N nodes and K keys, then each node is responsible for roughly K / N keys. When a new node joins or leaves the network, responsibility for O(K / N) keys changes hands. If each node knows only the ...
