The hierarchical routing and wavelength assignment problem in Automatic Switched Optical Network (ASON) is researched. Based on our analysis, three adaptive algorithms called MLLR (Multi-Layer Least Loaded Routing Algorithm), WMLCR (Wavelength-graph-based Multi-Layer Least Congestion Routing Algorithm) and BMR (Backtracking-based Multi-Layer Routing Algorithm) are proposed. A platform named AHORSP...
This paper considers the consensus of the leader-following systems with a discrete-time model. The velocity of the active leader is unknown in real time. This paper designs the control laws and observers based on the neighbors to solve the consensus problem. The Lyapunov approach has played an important role in the leader-following systems. It is shown that all agents asymptotically move with the...
Firstly, we give the definition of an L-bifuzzy Scott closed subset and prove its related properties, then, we give the definition of an L-bifuzzy Scott co-topological space, study its properties and equivalently characterize it which is a generalization of the Scott co-topological space in the classical topology theory. Finally, we establish the relationships of L-bifuzzy domain, L-bifuzzy lower...
A novel multi-domain L1VPN provisioning architecture is proposed based on service plane of the adaptive multi-services provisioning platform. Moreover, the architecture we proposed was experimentally demonstrated in our AMSON testbed.
Firstly, we present some characterizations of L-fuzzy poset and their corresponding proofs. Then, we give the definition of L-fuzzy upper set and prove its related properties. Next, we define the concept of L-fuzzy Co-Alexandrov topological space on an L-fuzzy poset (X, e). We further study the properties of L-fuzzy Co-Alexandrov topological space and equivalent characterizations, which are generalizations...
