设计了一种命名数据网络(NDN)下的分布式散列表(DHT)算法——ndnDHT,首次将 DHT 应用到NDN中;利用NDN的命名结构,提出了一种新的二进制命名方法,将key 空间映射到NDN 名字空间,以此实现DHT中的路由和转发等操作;设计了一种分配节点标识符的动态随机选择方法,使得ndnDHT算法的负载更加均衡;最后,基于NS-3和ndnSIM实现了ndnDHT算法,通过模拟实验验证了ndnDHT算法的可行性。
A novel distributed Hash table(DHT)algorithm under named data networking(NDN)
which was called ndnDHT
was proposed. The algorithm brings the DHT to NDN for the first time. A new binary method using the structure of NDN was designed. By mapping the key space to the space of NDN
the binary method solves the operations such as routing and retransmission. Besides
a dynamic selection method of node identifier distribution was proposed to balance the load of ndnDHT algorithm. Finally
ndnDHT algorithm based on NS-3 and ndnSIM was implemented. The experimental result shows that the ndnDHT algorithm is effective.
