“…The work in [29] provides a mathematical framework to calculate the success rate of different tiers of virtualized CDNs taking into account the QoE of the subscribers and the resources used by the virtualized cache nodes. In [30] the authors propose a Big Data architecture fulfilling the ETSI NFV guidelines, allowing to control the virtualized components of a cloud-based CDN for minimizing the CDN costs while ensuring the highest quality on the service delivery.…”

The consumption of video contents is currently dominating the traffic observed in ISP networks. The distribution of that content is usually performed leveraging on CDN caches storing and delivering multimedia. The advent of virtualization is bringing attention to the CDN as use case for virtualizing the cache function. In parallel, there is a trend on sharing network infrastructures as a way of reducing deployment costs by ISPs. Then, an interesting scenario emerges when considering the possibility of sharing virtualized cache functions among ISPs sharing a common physical infrastructure, mostly considering that usually those ISPs offer similar content catalogues to final end users. This paper investigates through simulations the potential efficiencies that can be achieved when sharing a virtual cache function if compared to the classical approach of independent virtual caches operated per ISP.

“…At the time of deploying CDN caches as VNFs, further optimization 31 can be considered in terms of retrieval cost of contents as well as the number of VNFs. Moreover, the work in Bulkan et al 32 provides a mathematical framework to calculate the success rate of different tiers of virtualized CDNs considering the QoE of the subscribers and the resources used by the virtualized cache nodes. Finally, Ruiz et al 33 propose a Big Data architecture fulfilling the ETSI NFV guidelines, allowing control of the virtualized components of a cloud‐based CDN for minimizing the CDN costs while ensuring the highest quality of the service delivery.…”

Video content consumption is currently dominating the mix of traffic observed in Internet service provider (ISP) networks. The distribution of that content is usually performed by means of content delivery network (CDN) caches storing and delivering multimedia. The advent of virtualization is calling attention to the CDN providers as a use case for virtualizing the cache function. In parallel, there is a trend for sharing network infrastructures as a way of reducing deployment costs by ISPs. Then, an interesting scenario emerges when considering the possibility of sharing virtualized cache functions among ISPs which are sharing a common physical infrastructure, mostly considering that those ISPs offer similar video content catalogs to end users. Furthermore, when deciding to share the caches among ISPs, it is interesting to understand the impacts due to limiting the storage capacity at the edge sites. This paper investigates through simulations the potential efficiencies that can be achieved when sharing a virtual cache function if compared with the classical approach of independent virtual caches operated per ISP, as well as the implications of limiting the storage capacity of the caches at the edge.

With the continuous development of modern science and technology, artificial intelligence has entered an unprecedented period of rapid development. It is profoundly changing all social strata, and with further changes, artificial intelligence has developed rapidly. In recent years, artificial intelligence has been used in broadcasting and hosting field for many times, which has attracted the attention of domestic and foreign media. The anchor of artificial intelligence is still constantly updated and iterated, It is gradually replacing a lot of simple and highly repetitive work. The media industry and academic circles are worried whether the artificial intelligence anchor will replace the broadcasting and hosting profession? Based on this reason, under the background of artificial intelligence, this paper discusses the educational reform of broadcasting and hosting art in Colleges and universities. It is found that 54% of the students are willing to learn the second type of broadcasting and hosting subject, and act as their own, 10% of the students hold an attitude of unwillingness, and the remaining 36% are indifferent.
