The deployment of micro-datacenters for network function virtualization (NFV) by Internet Service Providers creates opportunities for flow processing along the traffic path. On-path processing requires the discovery of the middleboxes that will be traversed by each flow and the assignment of network functions (NFs) to middleboxes, while preserving the order(More)
The migration of network functions (NFs) into virtualized network infrastructures brings significant benefits to enterprise networks, while creating opportunities for new cloud service models (i.e., NF-as-a-Service). Network service embedding (NSE) entails serious challenges, stemming from middle-box policies prescribed by network operators and the(More)
Universal access to Internet is crucial, and as such, there have been several initiatives to enable wider access to the Internet. Public AccessWiFi Service (PAWS) is one such initiative that takes advantage of the the available unused capacity in home broadband connections and allows Less-than-Best Effort (LBE) access to these resources, as advocated by(More)

Network function virtualization (NFV) brings significant benefits by outsourcing network functions (NFs) to virtualized datacenters and enabling new business models, e.g. NF as a service (NFaaS). In this respect, network service embedding (i.e., the mapping of service chains) raises significant challenges due to the need to preserve correctness and satisfy(More)
The advent of Network Function Virtualization (NFV) opens up new opportunities for scaling out network function (NF) instances to meet evolving demands. However, dynamic NF scaling in conjunction with the highly unbalanced Internet traffic can induce a high degree of processing load imbalance among the NF instances. In this respect, we present Distributed(More)
