Load and Proximity Aware Request-Redirection for Dynamic Load Distribution in Peering CDNs [chapter]

Mukaddim Pathan, Christian Vecchiola, Rajkumar Buyya
2008 Lecture Notes in Computer Science  
Peering between Content Delivery Networks (CDNs) endeavors to ensure that each user is served by an optimal Web server in terms of network cost, even under heavy load conditions.  ...  Therefore, a dominant factor for the success of peering between CDNs is to perform load distribution to handle highly skewed loads.  ...  This work is supported in part by the Australian Research Council (ARC), through the discovery project grant and Department of Education, Science and Training (DEST), through the International Science  ...

Multi-mode energy management for multi-tier server clusters

Tibor Horvath, Kevin Skadron
2008 Proceedings of the 17th international conference on Parallel architectures and compilation techniques - PACT '08  
Moreover, we rigorously investigate selection of the optimal number of spare servers for each power state, a problem that has only been approached in an ad-hoc manner in current policies.  ...  We develop a theoretical analysis of the corresponding power optimization problem and design an algorithm around the solution.  ...  Software The cluster is set up as a 4-tier Web server consisting of the following tiers: 1. A front load balancer tier with 1 machine statically allocated.  ...

Optimal server allocations for streaming multimedia applications on the Internet

Padmavathi Mundur, Poorva Arankalle
2006 Computer Networks  
The objective function in the TP is to minimize the cost of serving a video request from user population x using server y as measured by network distance.  ...  Server selection issues for Web-based applications in such an environment have been widely addressed; the selection is mostly based on proximity measured using packet delay.  ...  Limited resource availability at the central server can also be an overhead under high load. On the other hand, they have the advantage of a simple implementation.  ...
