以内容为中心的网络（CCN）倡导一种新的传输模型，专门针对命名数据通信。CCN传输与TCP/IP模型有三个不同之处：接收方的唯一端点、以点到多点方式进行的基于拉取的数据检索以及路径内缓存。传输控制机制的定义在CCN架构设计中以及更广泛的以信息为中心的网络范围内具有根本的重要性。在这项工作中，我们提出了一个联合逐跳和接收器驱动的兴趣控制协议（HR-ICP），以调节用户的请求（兴趣）无论是在接收器和中间节点通过兴趣整形。我们证明了HR-ICP是稳定的，并收敛到一个有效的和最大最小的公平均衡。与仅在接收端控制流量相比，HR-ICP加速了拥塞反应并降低了丢失率，正如我们通过CCN分组级模拟所示。在不同的网络场景中，我们强调了我们的解决方案在更快地收敛到最佳吞吐量，对行为不端的接收器和延迟敏感的应用程序的流保护的鲁棒性方面的优势。
Content-centric networking (CCN) advocates a new transport model tailored to named-data communication. Three features distinguish CCN transport from the TCP/IP model: unique endpoint at the receiver, pull-based data retrieval in a point to multi-point fashion and in-path caching. The definition of transport control mechanisms is of fundamental importance within the CCN architectural design and beyond, in the broader scope of information-centric networks. In this work, we propose a joint Hop-by-hop and Receiver-driven Interest Control Protocol (HR-ICP) to regulate user requests (Interests) either at the receiver and at intermediate nodes via Interest shaping. We prove that HR-ICP is stable and converges to an efficient and max-min fair equilibrium. Compared to controlling traffic only at the receiver, HR-ICP accelerates congestion reaction and reduces the loss rate, as we show by means of CCN packet-level simulations. In different network scenarios, we highlight the advantages of our solution in terms of faster convergence to the optimal throughput, robustness against misbehaving receivers and flow protection of delay-sensitive applications.
