以内容为中心的网络（CCN）通过其基于名称的传输模型利用网内缓存、多路径转发和多播交付，为高效的内容分发提供了一个有前途的平台。与与应用分离的IP传输不同，CCN中的接收器驱动的传输允许应用灵活地确定它们偏好的传输功能。为了实现高吞吐量和最小化延迟，最近已经提出了一对使用各种类型的请求消息的传输控制方法，但是仍然不清楚它们如何在应用需求和网络性能方面支持大规模应用。在这篇文章中，我们研究了三种类型的请求的有效性：“管道”，“符号兴趣”和“任何下一个数据包”，当它们被用作CCN网络中的传输控制方案时。我们对延迟、带宽开销和转发状态减少进行了几次性能评估，并确定了每种请求的特征和最佳用例以及潜在的挑战。
Content-centric networking (CCN) offers a promising platform for efficient content dissemination through its name-based transport model exploiting in-network caching, multipath forwarding, and multicast delivery. Unlike IP transport, which is separated from applications, the receiver- driven transport in CCN allows applications to flexibly determine the transport functionalities they prefer. To achieve high throughput and minimize latency, a couple of transport control methods using various types of request messages have recently been proposed, but it is still unclear how they can support massive applications in terms of both the application requirements and network performance. In this article, we investigate the effectiveness of three types of requests: "pipeline," "symbolic interest," and "any next packet," when they are used as the transport control scheme in a CCN network. We carry out several performance evaluations regarding the latency, bandwidth overhead, and forwarding state reductions, and identify the characteristics and best use cases of each type of request as well as the potential challenges.
