“…LRU, LFU), cache sizes should be large enough. For small caches, timing information in combination with sufficient upfront content request advertising [5] and recommendation based request overlap [13] can improve the cache performance dramatically. Though these mechanisms can also be applied on HTTP based content distribution, they introduce extra application state and algorithms, and don't result in a solution for our targets.…”

Abstract-In recent years, the networking community has put a significant research effort in identifying new ways to distribute content to multiple users in a better-than-unicast manner. Scalable delivery is more important now video is the dominant traffic type and further growth is expected. To make content distribution scalable, in-network optimization functions are needed such as caches. The established transport layer protocols are end-to-end, and do not allow optimizing transport below the application layer, hence the popularity of overlay application layer solutions located in the network. In this paper, we introduce a novel transport protocol, the Shared Content Addressing Protocol (SCAP) that allows in-network intermediate elements to participate in optimizing the delivery process, using only the transport layer. SCAP runs on top of standard IP networks, and SCAP optimization functions can be plugged-in the network transparently as needed. As such, only transport protocol based intermediate functions need to be deployed in the network, and the applications can stay at the topological end points. We define and evaluate a prototype version of the SCAP protocol using both simulation and a prototype implementation of a transparent SCAP-only intermediate optimization function.

“…In [3], we proposed an alternative approach to evaluate flow priority on the basis of the need-by time. Applying this approach to the semantic segmentation and late assembly paradigm, the assembly device-which is located close to the end user and reconstructs the video stream segment per segmentwill now add a delivery deadline per requested segment.…”

In the last decade, video distribution has evolved from analog broadcast to fully digital video. Today, users have the freedom to decide what to watch and when to watch it, using Internet video services. Recommendation and profiling systems are there to assist the user in creating a personalized content sequence. One step further, the content itself is personalized and enabled for interactive playout. Linear content such as daily news is analyzed, segmented, filtered, and reassembled per viewer based on his profile, preferences, and available time. The transport is typically performed in a unicast fashion from a central server, which places a high demand on the network since it prevents reuse. In this paper we introduce the paradigm of late assembly. Personalized and interactive videos are generated based on semantic segments and user profiles which are combined on intermediate nodes near the end user. Together with deadline scheduling and caching, an efficient transport is realized. An architecture and a prototype implementation of this system are presented. © 2011 Alcatel‐Lucent.
