论文摘要
多播（几乎）与互联网一样古老，已经成为提高网络效率的工具，但在许多关键用例中也可以实现目的地发现，尽管未对准经济利益已将其部署限制在域本地使用情况下。但是，多播技术的最新进展以及对IP多播可能不合适但网络级支持的新用例的识别可能是可取的动力，可以重新考虑对多播的旧观念及其在互联网上的使用。为此，我们回到了原始问题，该问题似乎是正确的答案，根据我们概述了多播打算要实现的新答案。这样做的关键是重新编制多播问题，以试图在语义和建筑上与不同的答案保持一致，为通过多播解决方案提供更多用例的机会，从而促进了在该领域进行更多研究的需求。我们的论文为多播提供了这种新的愿景，并研究了现有和新兴的多播解决方案的对齐方式，使我们为将来的研究制定了一条途径。
Multicast is (almost) as old as the Internet, having become a tool for increasing network efficiency but also enabling destination discovery in a number of key use cases, although misaligned economic interests have limited its deployment to domain-local usages. But recent advances in multicast technologies as well as the identification of new use cases for which IP multicast may be ill fitted yet network-level support may be desirable motivate to re-think old perceptions of multicast and its use in the Internet overall. For this, we return to the original question to which multicast is seemingly the right answer, based on which we outline emerging new answers to what multicast intends to achieve. Key to this is to re-formulate the multicast question in an attempt to semantically and architecturally align different answers, opening opportunities for more use cases to be served through multicast solutions, thus also driving the need for more research in this space. Our paper poses this new vision for multicast and investigates the alignment of existing and emerging multicast solutions with it, leading us to formulate a path for future research.
