在以内容为中心的网络中实现正确的兴趣转发和重传

Enabling Correct Interest Forwarding and Retransmissions in a Content Centric Network

J. J. Garcia-Luna-Aceves, Maziar Mirzazad-Barijough

摘要:

我们发现,在名称数据网络(NDN)和原来的内容为中心的网络(CCN)架构中使用的机制可能无法检测到兴趣循环,即使他们操作的网络是静态的,没有故障发生。此外,我们表明,没有正确的利益转发策略可以定义,允许兴趣聚合,并试图通过识别利益唯一检测兴趣循环。我们介绍SIFAH(策略与跳数的兴趣转发和聚合),第一个兴趣转发策略是正确的,在任何操作条件下的内容为中心的网络。SIFAH通过使转发信息库(FIB)存储到命名内容的下一跳和跳数,并且通过使每个兴趣声明所请求的内容的名称和从路由器转发兴趣到内容的跳数来操作。我们提出了使用ndnSIM模拟器比较CCN和NDN与SIFAH的模拟实验的结果。这些实验的结果说明了在CCN和NDN中聚合兴趣时未检测到的兴趣循环的负面影响,以及使用SIFAH的性能优势。

英文摘要:

We show that the mechanisms used in the name data networking (NDN) and the original content centric networking (CCN) architectures may not detect Interest loops, even if the network in which they operate is static and no faults occur. Furthermore, we show that no correct Interest forwarding strategy can be defined that allows Interest aggregation and attempts to detect Interest looping by identifying Interests uniquely. We introduce SIFAH (Strategy for Interest Forwarding and Aggregation with Hop-Counts), the first Interest forwarding strategy shown to be correct under any operational conditions of a content centric network. SIFAH operates by having forwarding information bases (FIBs) store the next hops and number of hops to named content, and by having each Interest state the name of the requested content and the hop count from the router forwarding an Interest to the content. We present the results of simulation experiments using the ndnSIM simulator comparing CCN and NDN with SIFAH. The results of these experiments illustrate the negative impact of undetected Interest looping when Interests are aggregated in CCN and NDN, and the performance advantages of using SIFAH.
