We demonstrated a novel metro-embedded datacenter architecture with intra-datacenter optical burst switching ring and inter-datacenter optical burst switching over wavelength switched optical network interconnections, and virtual datacenter provisioning under the coordination of SDN control plane.
A bidirectional micro-actuator powered by electrothermal force is successfully demonstrated under both dc and ac operations, without the assistance of magnetic field, using MetalMUMPs process. To achieve small stiffness without buckling, which tends to occur in V-shaped actuators, a new Z-shaped electrothermal actuator is designed. With the actuation current from to ...
EMKC is an explicit congestion control algorithm which is designed for high bandwidth delay product (BDP) networks. Although delay-independence is an appealing characteristic, the EMKC system developed in exhibits undesirable equilibrium properties and slow fairness convergence behavior. To overcome these drawbacks, we propose a new method called AEMKC (Advanced Exponential Max-Min Kelly Control)...
To effectively avoid congestion and take full advantage of bandwidth inside a network, routing optimization is needed for path selection over a set of equal-cost-multi-paths. In this paper, a Link-Criticality-based ECMP routing optimization algorithm is proposed. As the traffic in the network overlaps on some links, LCER selects the path with least link average utilization and hops for the ECMPs....
Multi-nexthop routing mechanisms is the key point in network congestion, and the essential question is how to forward packets among multi-nexthop to reach equiponderant forwarding. This paper proposes an equiponderant forwarding strategy in multi-nexthop routing, which forwards the packets according to the actual capability of each node, and resolves the equiponderant forwarding problem of multi-nexthop...
Edge detection is arguably the most important operation in low level computer vision. Mean shift is an effective iterative algorithm widely used in edge detection. But the cost of computation prohibits Mean shift algorithm for high dimensions feature space. In this paper, a fast adaptive mean shift algorithm is proposed for edge detection. It makes use of one approximate nearest neighbors search method,...
