Overlay networking: applications and research challenges
摘要
<正>Overlay networking is one of the perspective solutions to today’s Internet challenges. At basic service level
overlay networks can serve as a supplement and enhancement of existing services
such as routing and addressing. At high application level
overlay networks can be used for applications
which are difficult to deploy in existing IP architecture with some specific reasons
e.g.
they need high-level information
which is hard to obtain by underlying layers. To address the heterogeneity of today’s Internet
overlay networks provide ways to service availability and desirable performance while retaining scalability. In contrast to changing the existing network layer
overlay networks allow bootstrapping
which is most important in the development of Internet infrastructure. Various applications of overlay networking are clarified in this paper. Research challenges including routing and searching in overlay networking are also identified.
