Optimal orchestration of virtual network functions [PDF]
Computer Networks, 2018 -The emergence of Network Functions Virtualization (NFV) is bringing a set of novel algorithmic challenges in the operation of communication networks. NFV introduces volatility in the management of network functions, which can be dynamically orchestrated, i.e., placed, resized, etc. Virtual Network Functions (VNFs) can belong to VNF chains, where nodes

Generalized virtual networking: An enabler for service centric networking and network function virtualization [PDF]
2014 16th International Telecommunications Network Strategy and Planning Symposium (Networks), 2014 In this paper we introduce the Generalized Virtual Networking (GVN) concept. GVN provides a framework to influence the routing of packets based on service level information that is carried in the packets. It is based on a protocol header inserted between the Network and Transport layers, therefore it can be seen as a layer 3.5 solution.
