“…The basic framework to dynamically construct the cloudbased CDN was proposed in [2], wherein replica servers used to store copies of original content are virtually created and modified on the cloud infrastructure. P. Frangoudis presented the design of a content-delivery-network-as-a-service architecture, which enables a telecom operator to open up its cloud infrastructure for content providers [6].…”

“…A content delivery network (CDN) is a prevalently used media distribution system, where content delivery components are interconnected and transmit data from broadcasting and telecommunications systems. It can provide high-quality and scalable media services, while reducing service response time and network congestion [2]. All these advantages make more and more service providers to adopt CDNs for their content distribution [3].…”

Abstract-Sharing Content Delivery Network (CDN) technologies such as CDN interconnection and cloud-based CDN have facilitated access to the huge volume of content in a cost-effective way. However, content distribution through shared CDN nodes is vulnerable to a wide variety of uncertainties, including unexpected node failure, intentional node disruption for maintenance or potential discrimination of content based on ownership. Trustworthiness can be considered as a key property to overcome the perception of uncertainty before delivering content through sharing CDN infrastructure and provide reliable broadcasting and telecommunications services. Establishing trustworthiness in sharing CDN infrastructure is a challenging task in the absence of the referenced framework. Therefore, we propose a trustworthiness management framework for sharing CDN infrastructure.

“…For example, it needs to be ensured that precise timestamps are collected when needed. Preliminary solutions have been proposed, for instance a CDN architecture in which a virtual manager is used to manage the network based on monitoring probes with the help of utility functions [29].…”

The ever-increasing network traffic and user expectations at reduced cost make the delivery of high Quality of Experience (QoE) for multimedia services more vital than ever in the eyes of Internet Service Providers (ISPs Appl (2017) 76:22243-22266 focus on the user, has become essential as the first step in cost-effective provisioning of high quality services. With the recent changes in the perception of user privacy, the rising level of application-layer encryption and the introduction and deployment of virtualized networks, QoE monitoring solutions need to be adapted to the fast changing Internet landscape. In this contribution, we provide an overview of state-of-the-art quality monitoring models and probing technologies, and highlight the major challenges ISPs have to face when they want to ensure high service quality for their customers.

“…Most solutions, however, are server layer. For instance, DotSlash [198] In this work, we focus on the server layer by proposing the virtualization of a VoD CDN (section 4.5), allowing programmatic modifications in a CDN infrastructure designed for video distribution, in order to quickly adapt it to new operating conditions [125]. Before, in section 4.4, we introduce the module that will be incorporated in proposed framework, aimed to detect flash crowds or any other significant changes in monitored metrics by using information from the CDN Monitor.…”
