Data retrieval in Named Data Networking (NDN) is based on content names irrespective of their hosting location. The NDN architecture introduces original naming, forwarding and caching techniques to improve data delivery efficiency. These distinctive techniques make the TCP congestion control scheme not suitable for the NDN architecture. In particular, the in-network caching and the multi-path forwarding used in the NDN architecture lead to fluctuations in the Round Trip Time (RTT) measurements. This makes the Retransmission TimeOut (RTO) an unreliable congestion indicator. Thus, the congestion problem in Named Data Networks deserves to be reconsidered. In this paper, we present a new congestion control algorithm, called IRNA (Interest Rate Notification and Adjustment), to mitigate the congestion problem in Named Data Networks while maintaining per flow and per consumer fairness property. More specifically, IRNA is a hop-by-hop scheme where each router monitors the occupation level of its outgoing queues to detect in advance potential congestion events. When the queue size is above or below a preset threshold, the router sends explicit notifications to its downstream nodes to specify the appropriate interest rate. Hence, by cooperatively adjusting the Interest transmission rate of each node and for each flow, IRNA succeeded to provide a fair transmission. We evaluated the performance of our solution using ndnSIM simulations. We compared IRNA to state-of-the-art hop-by-hop congestion control solution and we proved that IRNA managed to provide a faster congestion reaction and to achieve per flow and per consumer throughput fairness while maintaining a good bandwidth usage.

公平的逐跳利率控制以缓解命名数据网络中的拥塞

命名数据网络(NDN)中的数据检索基于内容名称,而不管其托管位置如何。NDN体系结构引入了原始的命名,转发和缓存技术,以提高数据传递效率。这些独特的技术使TCP拥塞控制方案不适用于NDN体系结构。特别是,在NDN体系结构中使用的网络内缓存和多路径转发会导致往返时间(RTT)测量的波动。这使重传超时(RTO)成为不可靠的拥塞指示器。因此,命名数据网络中的拥塞问题值得重新考虑。在本文中,我们提出了一种新的拥塞控制算法,称为IRNA(利率通知和调整),在保持每个流和每个消费者公平性的同时减轻命名数据网络中的拥塞问题。更具体地说,IRNA是逐跳方案,其中每个路由器监视其传出队列的占用级别,以预先检测潜在的拥塞事件。当队列大小大于或小于预设阈值时,路由器会向其下游节点发送明确的通知,以指定适当的利率。因此,通过合作调整每个节点和每个流的兴趣传输速率,IRNA成功提供了公平的传输。我们使用ndnSIM仿真评估了我们解决方案的性能。
