In this paper, we present a design for implementing network-based virtual Ethernet switches (NVESs) on top of a physical substrate consisting of a software-defined networking (SDN) network. An NVES has the same capability as a real Ethernet switch. A user makes a request to provision an NVES by specifying the number of ports and the maximum bandwidth for each port. The substrate network considered...
Network-on-Chip (NoC) has been proposed as a solution for the communication challenges of Multi-Processor System-on-chip (MPSoC) design in nanoscale technologies and it has better reusability and scalability. However along with the advantages of any communication parameter follow its disadvantages. Most state-of-the-art NoC architecture and their design flows is optimized for a single application,...
In an OpenFlow network, the controller is responsible to control and manage the whole network. Although such central control paradigm is easier to achieve efficient network resources usage, the controller becomes the bottleneck when the network size is large. In this paper, we propose using pre-provisioned paths to mitigate the burden on a controller. The basic idea is to setup some background paths...
In this work, we address the Routing and Time slot Assignment (R&TA) problem in multi-hop PLC access networks. In our system, time is divided into fixed sized TDM cycles. Each cycle comprises a semi-dynamic bandwidth allocation period (SBAP) and a dynamic bandwidth allocation period (DBAP). The SBAP is used to provide each PLC CPE fixed bandwidth for providing bandwidth guaranteed services. It's...
Survivability and energy efficiency are in conflict with each other on network resources usage in IP networks. The basic principle to achieve high survivability is via provisioning backup paths over spare capacity. However, in designing an energy efficient network, the target is the opposite. In order to minimize energy consumption, routing and traffic engineering techniques are applied to aggregate...
In order to reduce the greenhouse effects and environmental pollution, energy saving has become important in designing next the generation networks. Shutting down the network devices carrying light loads and redirecting the traffic flows to other routes is a way to decrease network energy consumption. Since traffic demands among node pairs vary in different time periods, the energy efficient network...
As a failure occurs, the affected traffic is quickly switched to backup paths for a network performing a fast IP rerouting. However, the rerouted traffic may cause congestion along the backup paths that would result in more packet losses than purely discarded the affected flows. In this paper, we take the concept of interface specific forwarding (ISF) to provide more flexibility in determining load...
As a failure occurs, the affected traffic is quickly rerouted to backup paths for a network performing a fast protection scheme. Such a prompt reaction is aimed to reduce the damages caused by a failure. However, in some cases, the rerouted traffic may cause congestion along the backup paths which would lead to more packet losses than purely discarded affected flows. In this paper, we propose a load-balanced...
Network coding has been proven with the capability to improve the network bandwidth efficiency for multicast communications. Streaming based IPTV services provided by network operators match the paradigm of using network coding. However, the major research works in the literature focus on the selection of network codes under given routing paths. Few research work jointly considers routing and network...
In this paper, we propose a non-weighted load balanced fast local protection scheme for survivable IP networks. Unlike conventional shortest path based routing, we relax shortest path constraints in computing working and backup routes to achieve load balancing purposes. Once a failure occurs, those nodes adjacent to the failure point use their backup routing tables to achieve fast local failure recovery...
