With the expansion of optical networks, the failure probability of dual-link failure has also improved, so it is urgent to find novel protection structures to deal with dual-link failure. In this paper, we mainly focus the protection structures to solve the problem. Firstly, we describe the scenarios and the problem of dual-link failure. Then, theory of pre-configured polyhedron (p-Poly) is introduced...
Through-silicon via (TSV) could provide vertical connections between different dies in three-dimensional integrated circuits (3D ICs), but the significant silicon area occupied by TSVs may bring great challenge to designers in 3D clock tree synthesis (CTS) because only few whitespace blocks can be used for clock TSVs after floorplan and placement. Unlike most of the published previous works that ignore...
There are two causes of network congestion: one is the lack of network resources, and the other is the irrational allocation of network resources. While traditional congestion control methods such as rate control, window mechanism, queue control, etc. can be applied to solve the congestion problem, but for the later congestion case, the fundamental solution is to make more effectively use of the network...
A fast rerouting scheme is proposed to guarantee the QoS performance of rerouted path when handling link and node failures. The new scheme is based on deflection routing mechanism and improves on two aspects: first, it can promptly handle single node failure as well as single link failure, second, QoS metric is taken into accounted when calculating recovery routes. Simulation results show that the...
