2018 2018 4th IEEE Conference on Network Softwarization and Workshops (NetSoft)  
We formulate the problem as an Integer Linear Program (ILP) and propose a Pattern-based Cost-efficient Proactive VNF placement and chaining (PCPV) algorithm.  ...  Value-added services (VASs) are an integral part of todays Content Delivery Networks (CDNs). They can be implemented as a chain of Virtual Network Functions (VNFs).  ...  PATTERN-BASED COST-EFFICIENT PROACTIVE VNF PLACEMENT (PCPV) PCPV is run once for each SC which is accessed by a set of EUs.  ...
