Overlay mapping provides a flexible and effective means of application deployment by
selecting a subset of nodes and links from the substrate-hosting network to meet, or even …

In this paper, we investigate the issue of how to map an application request upon a substrate
network in such a way that the selected hosting node and link sets can provide not only …

The problem of overlay mapping with enhanced resilience and QoS is NP-hard and
previous heuristics are oblivious to substrate topology information and thus cannot provide …

We describe QoSMap, a novel approach for mapping overlay networks with stringent QoS
requirements. QoSMap computes high quality overlay paths by utilizing direct underlay …

A network defines its own Quality-Of-Service (QoS) class and has QoS support mechanisms.
So, effectively to support end-to-end QoS in heterogeneous networks, a certain unified …

Each network has its own distinct quality of service (QoS) class. To support end-to-end QoS
QoS class interwoking between different network technologies is very important function …

We describe QoSMap, an overlay construction mechanism which computes high quality
overlay networks for applications having stringent constraints on hop-degrading QoS metrics …

Overlay networks are being increasingly used to deploy new services on the Internet. As
opposed to peer-to-peer overlays, these infrastructure or service overlays offer the …

We describe QoSMap, an efficient and flexible mechanism for constructing virtual networks
on a shared Internet substrate for applications having stringent QoS and resiliency …

This paper proposes a Resilient Overlay for Mission Critical Applications (ROMCA); a novel
operator-independent overlay architecture providing a resilient and reliable service across …
