Overlay networks are expected to operate in hostile environments where node and link failures are commonplace. One way to make overlay networks robust is to design self-stabilizing overlay networks, i.e., overlay networks that can handle node and link failures without any external supervision. In this paper, we first describe a simple framework, which we call the Transitive Closure Framework (T...

In the past few years, overlay networks have received much attention but there has been little study on the “interaction” of multiple, co-existing overlays on top of a physical network. In addition to previously introduced concept of overlay routing strategy such as selfish routing, we introduce a new strategy called “overlay optimal routing”. Under this routing policy, the overlay seeks to min...

Overlay networks have been used for adding and enhancing functionality to the end-users without requiring modifications in the Internet core mechanisms. Overlay networks have been used for a variety of popular applications including routing, file sharing, content distribution, and server deployment. Previous work has focused on devising practical neighbor selection heuristics under the assumpti...

Dynamic overlay routing has been proposed as a way to enhance the reliability and performance of IP networks. The major premise is that overlay routing can bypass congestion, transient outages, or suboptimal paths, by forwarding traffic through one or more intermediate overlay nodes. In this paper, we perform an extensive simulation study to investigate the performance of dynamic overlay routin...

Overlay journals are not a new concept but have been experiencing recent resurgence because of the increase in number preprint servers and preprints on coronavirus disease 2019 (COVID-19) related topics. This study examines overlay at various stages maturity for unique characteristics, including whether authors submitted their article to journal reviews published by journal. Whether they consid...
