“…The cacheability in data volume drops further due to the viewing pattern for large size content, such as videos. Detailed analysis of YouTube video [5] and various other internet user generated content (UGC) [6] show most of users finish less than 10% of the length of the video they view.…”

An explosive growth of the use of the public internet by mobile phones along with new high speed data technologies increases the challenge of mobile data delivery. The owners of popular media typically use content delivery networks (CDN) to distribute their content. Currently there is no collaboration between the CDNs and the mobile networks.In this paper we present a novel method for caching at the edge of small cell wireless networks. Our solution allows the small cell network operator to control and manage the access to the storage system at the edge of the small cell network while delegating to the CDN provider the task of managing the content placement.We define a managed caching architecture that consists of new components deployed in the mobile core networks and within the small cell network. These components are interconnected amongst themselves and with an external CDN using newly defined interfaces which are designed using existing OpenAPI and TR-69 standards.

“…In a bid to deal with unmanaged content and improve average response time for their customers and reduce the traffic on expensive international links, several operators deployed TIC (Transparent Internet Caching). However, its utilization is impacted by cache-ability and homogeneity of the content [3].…”

Transparent Internet Caching is a solution that enables the service provider to offload a significant amount of content in a cached copy of the popular content close to the edge of the network, which is delivered to an end-user directly from the edge of the network rather than from the source. We propose state-driven TIC service orchestration over the decomposed service functions based on NFV and SDN technologies.

“…The results from the studies [10], [11], [12] illustrate the exponential increase in video traffic redundancy and also state that in the year 2018 79% of global IP traffic will be video. In 2018, the sheer amount of VOD on the internet will be equivalent to 6 billion DVDs per month.…”

Statistics show that 79% of the Internet traffic is video and mostly "redundant". Video-On-Demand in particular follows a 90/10 access pattern, where 90% of the users access the same 10% of all video content. As a result, redundant data are repeatedly transmitted over the Internet. In this paper, we propose a novel traffic deduplication technique to achieve more efficient network communication between video sources (video servers or proxy servers in a CDN) and clients. The proposed SMART (Small packet Merge-Able RouTers) overlay network employs an opportunistic traffic deduplication approach and allows each SMART router to dynamically merge independent streams of the same video content, forming a video streaming tree (VST). The merged streams are tunneled through the overlay together with TCP sessions information before eventually being de-multiplexed and delivered to the clients fully compatible with the TCP protocol. We present theoretical analysis findings on the merging strategy between the video source and clients, the efficiency of the SMART router to save traffic during a merge process, and the overall performance of implementing a SMART overlay topology between a video source and clients. Finally, we prototyped SMART in the PlanetLab environment. We illustrate that performance evaluation results are consistent with our theoretical analysis and significant bandwidth saving is achieved.
