    Content Delivery Networks (CDN) play a key role in multimedia distribution in today's Internet in order to achieve more efficient bandwidth management, reliability, and Quality of Service (QoS). This paper proposes an advanced CDN solution for enhancing the delivery and caching of adaptive HTTP-based video streaming that dominates consumer video service distribution today. The paper also presents a testbed implementation of the proposed system, utilizing open source components and a standardized MPEG-DASH based video streaming solution. The proposed CDN management features and the associated signaling are inspired by the upcoming MPEG standard for Server and Network assisted DASH (SAND). The paper also presents selected results obtained from an experimental evaluation. The results attest the benefits of the proposed solution in enhancing MPEG-DASH delivery in CDNs for the selected test cases.
