前向纠错（FEC）编码技术的最新进展集中于解决多播和广播递送的挑战。然而，FEC方法也可以用于单播内容递送，以便解决在无线网络中发现的传输控制协议问题。在本文中，我们利用Raptor码的错误恢复特性，提出基于Raptor的内容传输协议（RCDP）-一种新的解决方案，用于在有损链路中进行可靠的双向单播通信，可以提高无线网络成为瓶颈的情况下的内容传输。RCDP已经过设计、验证和优化，并在吞吐量和资源效率方面对其性能进行了分析。实验结果表明，RCDP是一个高效的解决方案，其特点是高延迟和数据包丢失的环境，使其非常适合面向智能传输系统的应用程序，因为它实现了显着的性能改善时，相比传统的传输层协议。
Recent advances in forward error correction (FEC) coding techniques were focused on addressing the challenges of multicast and broadcast delivery. However, FEC approaches can also be used for unicast content delivery in order to solve transmission control protocol issues found in wireless networks. In thispaper, we exploit the error resilient properties of Raptor codes by proposing Raptor-based content delivery protocol (RCDP) — a novel solution for reliable and bidirectional unicast communication in lossy links that can improve content delivery in situations where the wireless network is the bottleneck. RCDP has been designed, validated, optimized, and its performance has been analyzed in terms of throughput and resource efficiency. Experimental results show that RCDP is a highly efficient solution for environments characterized by high delays and packet losses making it very suitable for intelligent transport system oriented applications since it achieves significant performance improvements when compared to traditional transport layer protocols.
