随着互联网提供单一的尽力而为的服务，已经有许多多样化的网络服务的建议，更好地配合不同的分布式应用程序的不同需求。这些创新架构未能获得广泛部署主要是由于经济和遗留问题，而不是技术缺陷。我们提出了一个新的模式，网络服务的差异化，设计原则明确考虑到互联网服务提供商和用户的多样性，以及他们的经济利益的环境中，部分部署的新服务。我们的核心理念是将服务差异化建立在性能本身，而不是价格上。所提出的RD（速率延迟）服务使得用户能够在拥塞的网络链路处在较高的传输速率或低的排队延迟之间进行选择。RD路由器通过在每个输出链路上维护两个队列来支持这两种服务，并通过简单的链路调度和动态缓冲区大小调整来实现预期的速率延迟差异。在分析得出RD路由器操作的具体规则后，我们进行了广泛的模拟，确认面向增量部署在互联网上的RD服务的有效性。
With the Internet offering a single best-effort service, there have been numerous proposals of diversified network services that align better with the divergent needs of different distributed applications. The failure of these innovative architectures to gain wide deployment is primarily due to economic and legacy issues, rather than technical shortcomings. We propose a new paradigm for network service differentiation where design principles account explicitly for the multiplicity of Internet service providers and users as well as their economic interests in environments with partly deployed new services. Our key idea is to base the service differentiation on performance itself, rather than price. The proposed RD (Rate-Delay) services enable a user to choose between a higher transmission rate or low queuing delay at a congested network link. An RD router supports the two services by maintaining two queues per output link and achieves the intended rate-delay differentiation through simple link scheduling and dynamic buffer sizing. After analytically deriving specific rules for RD router operation, we conduct extensive simulations that confirm effectiveness of the RD services geared for incremental deployment in the Internet.
