Robust CDN Replica Placement Techniques

Download Now Free registration required

Executive Summary

Creating replicas of frequently accessed data objects across a read-intensive Content Delivery Network (CDN) can result in reduced user response time. Because CDNs often operate under volatile conditions, it is of the utmost importance to study replica placement techniques that can cope with uncertainties in the system parameters. The authors propose four CDN replica placement heuristics that guarantee a robust performance under the uncertainty of arbitrary CDN server failures. By robust performance they mean the solution quality that a heuristic guarantees given the uncertainties in system parameters.
