CPVNF:Cost-efficient Proactive VNF Placement and Chaining for Value-Added Services in Content Delivery Networks [article]

Mouhamad Dieye, Shohreh Ahvar, Jagruti Sahoo, Ehsan Ahvar, Roch Glitho, Halima Elbiaze, Noel Crespi
2018 arXiv   pre-print
Apart from cost minimization, the support for large-scale CDNs with a large number of servers and end-users is an important feature of the proposed algorithm.  ...  We formulate it as an Integer Linear Program (ILP) and propose a cost efficient Proactive VNF placement and chaining (CPVNF)algorithm.  ...  First, the services must be delivered to end-users with high QoS (e.g., reduced service delay). It is in fact desirable to provide the service with a strict QoS guarantee.  ...
