Emerging paradigms, such as edge computing, require the geographical distribution of small-scale data centers that will use network functions virtualization (NFV) to provide new services with stringent demands related to throughput, latency, cost, innovation, and efficient orchestration. To tackle these demands, this paper proposes VirtPhy, a fully programmable architecture for NFV orchestration in...
This paper proposes, implements, and evaluates VirtPhy, a novel approach to build small-scale data centers network infrastructure for network functions virtualisation (NFV). VirtPhy is fully programmable to respond to NFV stringent demands related to throughput, latency, cost, rapid innovation, and efficient orchestration. An 8-node testbed demonstrates its key enabling mechanisms, which are programmed...
This paper proposes KAR (Key-for-Any-Route), a new intra-domain resilient routing system in which edge-nodes set a route ID to select any existing route as an alternative to safely forward packets to their destination. In KAR routing system, a route is defined as the remainder of the division between a route ID and a set of switch IDs along the path(s) between a pair of nodes. KAR-enabled switches...
