It is a widely accepted notion that the native layer of the current Internet has begun to
stagnate in terms of the services offered. Consequently, overlay networks have gained …

In the past ten years of the Internet's evolution, we have seen a tremendous increase in
complexity and processing power of end-systems, leading to a higher level of collaboration …

Overlay networks create virtual topologies on top of the existing networking infrastructure
and come as a middle layer between end-user applications and the basic network services …

Nowadays, a very useful platform is becoming widely used to deploy new services and
applications in the Internet: the overlay networks. These networks create a virtual topology …

The Achilles heel of the otherwise extremely successful Internet infrastructure has been its
rigidity, which has primarily stemmed from the ossification of shortest-path routing in the …

Recently, overlay networks have emerged as a means to enhance end-to-end application
performance and availability. Overlay networks attempt to leverage the inherent redundancy …

An emerging generation of mission-critical networked applications is placing demands on
the Internet protocol suite that go well beyond the properties they were designed to …

One can verify in the literature dealing with overlay networks that there exists a lot of overlay
networks with a lot of different purposes and applications such, file indexing/sharing …

The lack of infrastructural functionality in IP-based networks has led to the creation of many
overlay network algorithms where application-level nodes self-organize, forming an overlay …

Network-overlay construction today assumes two-way communication capability-each host
can initiate outgoing connections as well as accepting incoming connections. This is often …
