Question

rcular DHT. The node IDs are shown in the figure below. Assume that e DHT only knows two peers, its immediate successor and its immediate Considering a circular Di each node in the DH predecessor. [10 points] (a) If Node 13 query message vode 13 wants to know who is responsible for Key 1. how many hops does its ry message will be transmitted before reaching the peer that is responsible for Key 1? What is an important disadvantage of this approach, given the messages are routed according to the ring topology of the overlay? Describe a method to improve the above disadvantage. N 15 13

Answer 1

Page 1 Ansurir 13 a) Q hops : b) All data being transfered over the network must pass through cach work station on the network which can make is slower than a star to Pology. Scarined with si camScanner
