Cost-Effective Resource Allocation of Overlay Routing Relay Nodes

Internet is the most popularly used application all over the world. The main aim of the Internet is to provide end to end services and a variety of information and communication facilities with high availability and faster response. Variety of work is done and continuously in progress to detect and reduce factors that affect Internet availability. The link and router failures along with some other factors mainly affect the Internet performance. One way to improve Internet behavior is to spread intelligent routers all over network those manage traffic through other intermediaries. Such intelligent nodes called as relay nodes or overlay nodes, and path travel through them called as overlay path whereas the resultant system is called overlay network. These nodes operate dynamically and provide an extra functionality to existing infrastructure. Different overlay networks offering different services may place on same substrate at same time and substrate must allocate resources fairly to them. The Overlay Routing Resource Allocation (ORRA) technique provides a general framework structure that can be used in variety of applications and offer low maintenance as compared to other overlay systems like Resilient Overlay Network (RON), Detour etc.
