Virtual Content Delivery Network (vCDN) orchestration is necessary to optimize the use of resources and improve the performance of the overall SDN/NFV-based CDN function in terms of network operator cost reduction and high streaming quality. It requires intelligent and enticed joint SDN/NFV orchestration algorithm due to the evident huge amount of traffic to be delivered to end customers of the network. In this paper, a global vCDN architecture and an exact approach for finding the optimal path…

Virtual functions orchestration costs : from identification to prediction
TLDR
This work utilizes a well-known container platform to perform a series of experiment to assert the associated cost posed by the orchestration of virtualized functions, and results indicate that predictions can be accurate within reasonable range, and therefore future orchestration algorithms may benefit from considering such predictions when defining the best orchestration plan available.

An orchestrated 5G‐enabled deep vCDN system
TLDR
A novel orchestration framework for deep and 5G‐enabled vCDN services is proposed, and builds on two main capabilities: a) the dynamic provisioning of v CDN Edge nodes, enabling content placement at the network Edge based on nearby user's presence, and b) Preemptive video content placement, for users rapidly moving between different edge regions.
Application, Workload, and Infrastructure Models for Virtualized Content Delivery Networks Deployed in Edge Computing Environments
TLDR
It has been shown that leveraging edge resources for the deployment of caches of content greatly benefits CDNs, and the models are described from an edge computing perspective and intended to be integrated in network topology aware application orchestration and resource management systems.
Multi-Tier Caching Analysis in CDN-Based Over-the-Top Video Streaming Systems

This paper proposes a model for video streaming systems, typically composed of a centralized origin server, several CDN sites, and edge-caches located closer to the end user, and comprehensively considers different systems design factors.
Virtual CDN Providers: Profit Maximization through Collaboration
TLDR
The overall problem of content placement for multiple vCDN providers that employ collaboration as an overall social-welfare maximization problem is formulated and a distributed algorithm for content placement is devised by exchanging limited information among them.
Content Delivery Networks - Q-Learning Approach for Optimization of the Network Cost and the Cache Hit Ratio
TLDR
A Content Delivery Network model is proposed that allows us to choose the best trade-off between costs and cache hit ratio and it is shown that the current model is inadequate.
