This paper focuses on the concept of multi-path virtual concatenation as a key enabling technology to support the requirements of spectrum bandwidth of link mapping in the process of virtual network embedding (VNE). A dynamic VNE_MP algorithm for distributed data centers inter-connecting is proposed. Based on the multi-path virtual concatenation mechanisms, a virtual link is split into multiple smaller...
To measure the survivability of virtual optical network embedding, a novel metric named virtual optical network failure probability (VON-FP) is presented in elastic optical networks. We then develop a failure-probability-aware virtual optical network embedding (FPA-VONE) algorithm considering different line rates to decrease VON-FP of each VON. Simulation results show that FPA-VONE provides lower...
A compact L-shaped strip fed air-supported microstrip antenna with a simple structure is proposed at UHF band. This linear polarized microstrip antenna (LPMA) is miniaturized by bending both opposite sides of the antenna. To achieve the low profile, the L-shaped feeder, compensating the reactive of the antenna, has been designed. The dimensions of the proposed antenna are 200 mm×200 mm×15 mm (0.27λ...
The development of Smart Gird has higher demand on the support of electric power telecommunication network. Considering the “strong smart Grid construction and development mode, service modeling, bandwidth prediction and plan technology of electric power telecommunication network which covers the main parts of smart grid (Generation, Transmission and Power Dispatching) is studied in this paper. Then...
For realizing the multi-services optimal transmission in the generalized optical burst switching (G-OBS) network, this paper proposed an intelligent services-aware burst assembly mechanism to maximize burst utilization and enhance scheduling flexibility.
