PROJECT TITLE :

Utility-Centric Networking: Balancing Transit Costs With Quality of Experience - 2018

ABSTRACT:

This Project is concentrated on techniques for maximizing utility across all users within a total network transit price budget. We have a tendency to gift a replacement method for selecting between replicated servers distributed over the Internet. Initial, we introduce a unique utility framework that factors in quality of service metrics. Then we have a tendency to style an optimization algorithm, solvable in polynomial time, to allocate user requests to servers primarily based on utility while satisfying network transit value constraints, mapping service names to service instance locators. We have a tendency to then describe an economical, low overhead distributed model which only needs knowledge of a fraction of the info required by the worldwide optimization formulation. Next, a load-balancing variant of the algorithm is explored that substantially reduces blocking caused by congested servers. Extensive simulations show that our method is scalable and ends up in higher user utility compared with mapping user requests to the closest service duplicate, whereas meeting network traffic cost constraints. We have a tendency to discuss several choices for real-world deployment that need no changes to end-systems based on either the employment of SDN controllers or extensions to the current DNS system.
