Summary
The Time Shared Optical Network (TSON) offers a novel metro mesh architecture for guaranteed services. This approach enhances network utilization and speeds up service delivery in optical transport networks.
Area of Science:
- * Computer Science
- * Electrical Engineering
- * Telecommunications Engineering
Background:
- * Existing metro mesh network architectures often struggle to provide guaranteed, statistically-multiplexed services efficiently.
- * The need for flexible and granular service delivery in optical transport networks is increasing.
Purpose of the Study:
- * To introduce and evaluate the Time Shared Optical Network (TSON) as a metro mesh architecture.
- * To demonstrate TSON's capability for guaranteed sub-wavelength and multi-granular services.
- * To assess the implementation complexity of TSON.
Main Methods:
- * Development of a flexible and tunable time-wavelength assignment mechanism.
- * Implementation of a one-way tree-based reservation and node architecture.
- * Simulation of the TSON architecture on a contention-free sub-wavelength optical transport network.
Main Results:
- * Achieved high network utilization.
- * Demonstrated fast service delivery with low end-to-end delay.
- * Evaluated Layer 2 aggregation, grooming, and optical switching implementation complexity.
Conclusions:
- * TSON provides a viable solution for guaranteed, statistically-multiplexed services in metro mesh networks.
- * The proposed architecture efficiently delivers sub-wavelength and multi-granular services without complex optical components.
- * TSON shows promise for high-performance optical transport networks.

01:27Transformers in Distribution System
Transformers in distribution systems can be broadly categorized into distribution substation transformers and other distribution transformers. They are crucial for stepping down high transmission voltages to levels suitable for distribution and end-user applications.
Distribution substation transformers come in various ratings and typically use mineral oil for insulation and cooling. To prevent moisture and air from entering the oil, some transformers use an inert gas like nitrogen to fill the...

01:22Fiber Reinforced Concrete
Fiber-reinforced concrete significantly enhances the structural and nonstructural properties of traditional concrete by incorporating fibers like steel, glass, and polymers. These fibers, varying from natural ones such as sisal and cellulose to manufactured ones like polypropylene and Kevlar, are mixed into hydraulic cement with aggregates. Steel fibers, often preferred for their robustness, contribute to improved ductility, toughness, and post-cracking performance. The concrete is classified...
02:12Short-distance Transport of Resources
Short-distance transport refers to transport that occurs over a distance of just 2-3 cells, crossing the plasma membrane in the process. Small uncharged molecules, such as oxygen, carbon dioxide, and water, can diffuse across the plasma membrane on their own. In contrast, ions and larger molecules require the assistance of transport proteins due to their charge or size. Transport across membranes also occurs within individual cells, playing a variety of essential roles for the plant as a whole.
