The Internet architecture has proven its worth by the vast array of applications it now
supports and the wide variety of network technologies over which it currently runs. Most …

Quality of Service Routing is at present an active and remarkable research area, since most
emerging network services require specialized Quality of Service (QoS) functionalities that …

PlanetLab is a geographically distributed overlay network designed to support the
deployment and evaluation of planetary-scale network services. Two high-level goals shape …

Today's Internet architecture provides only “best effort” services, thus it cannot guarantee
quality of service (QoS) for applications. Software Defined Network (SDN) is a new approach …

Recently, many overlay applications have emerged in the Internet. Currently, each of these
applications requires their proprietary functionality support. A general unified framework may …

Embedding of virtual network (VN) requests on top of a shared physical network poses an
intriguing combination of theoretical and practical challenges. Two major problems with the …

We argue that designing overlay services to independently probe the Internet--with the goal
of making informed application-specific routing decisions--is an untenable strategy. Instead …

We propose a novel application-level virtual network architecture called VIOLIN (Virtual
Internetworking on OverLay INfrastructure). VIOLINs are isolated virtual networks created on …

Providing end-to-end quality of service (QoS) support is essential for video delivery over the
next-generation wireless Internet. We address several key elements in the end-to-end QoS …

Many value-added and content delivery services are being offered via service level
agreements (SLAs). These services can be interconnected to form a service overlay network …
