“…For video services, operators, and broadcasters, QoE has become a service differentiator next to the number of channels or the content they offer [10]. Moreover, QoE has become a key factor in routing mechanisms and resource management schemes for network operators and IPTV providers [11].…”

“…The proposed approach, called PG 2 BR (Parameterized Green Gradient Based Routing), extends from our original Parameterized Gradient Based Routing (PGBR) [4]. The strength of PG 2 BR is the ability to adaptively modify the topology without prior knowledge of the traffic demand, by including a new functionality that monitors and powers routers on/off (two-phase mechanism) to adapt to the traffic demand.…”

This paper proposes a distributed routing protocol that minimizes the energy consumption of communication networks. The proposed protocol, called PG 2 BR (Parameterized Green Gradient Based Routing) contains a dual process, which includes i) a two-phase mechanism that gradually powers devices on/off in a decentralized manner, depending on the traffic condition, and ii) a distributed gradient based routing that quickly adapts to topology changes while maximizing resource usage and maintaining QoS requirements. Simulation work on a number of different types of topologies, have shown that PG 2 BR is highly adaptive to any traffic and network conditions while proposing the best energy savings-QoS trade-off.

“…IPTV's deployment investment to address this opportunity is two-fold, consisting of both improvements in the underlying infrastructure as well as provisioning and managing the vast data centers needed to provide IPTV [3]. Recent work has explored strategies for coordinating the allocation of resources for multiple virtual IPTV providers to maximize revenue [4] and routing strategies to manage network resources when multiple IPTV services are overlaid on the same network [5]; however, the fundamental problem -indeed an integral part of satisfying customer expectation-lies in evaluating the quality of the IPTV service being provided and then giving guidance on how delivery can be improved. In this paper, we take a first systemic view of IPTV monitoring: we consider what metrics should be collected, where metrics should be collected, and how these metrics should be presented to a Network Manager (NM) in a semantically enriched way via standard Real-Time Control Protocol (RTCP) reports.…”

Increasing and variable traffic demands due to triple play services pose significant Internet Protocol Television (IPTV) resource management challenges for service providers. Managing subscriber expectations via consolidated IPTV quality reporting will play a crucial role in guaranteeing return-on-investment for players in the increasingly competitive IPTV delivery ecosystem. We propose a fault diagnosis and problem isolation solution that addresses the IPTV monitoring challenge and recommends problem-specific remedial action. IPTV delivery-specific metrics are collected at various points in the delivery topology, the residential gateway and the Digital Subscriber Line Access Multiplexer (DSLAM) through to the video Head-End. They are then pre-processed using new metric rules. A semantic uplift engine takes these raw metric logs; it then transforms them into World Wide Web Consortium (W3C)'s standard Resource Description Framework (RDF) for knowledge representation and annotates them with expert knowledge from the IPTV domain. This system is then integrated with a monitoring visualization framework that displays monitoring events, alarms, and recommends solutions. A suite of IPTV fault scenarios is presented and used to evaluate the feasibility of the solution. We demonstrate that professional service providers can provide timely reports on the quality of IPTV service delivery using this system.Neither the entire paper nor any part of its content has been published or has been accepted for publication elsewhere.
