Optical switching

Bài này nhằm cung cấp cho học viên các kiến thức và kỹ năng về: vì sao mô hình chuyển mạch gói quang được đề xuất một số mô hình chuyển mạch gói quang tiêu biểu những cản trở đối với sự phát triển của mô hình chuyển mạch gói quang . Không giống như mạng kỹ thuật chuyển mạch kênh (circuit) WDM, chuyển mạch gói quang OPS (optical packet switching) vẫn đang giai đoạn phát triển. Mặc dù đã có các thực nghiệm được thực hiện ở một số dự án cấp đại học hay công ty [8]-[10], OPS vẫn phụ thuộc...

Transmission: the propagation of a signal, message, or other form of intelligence by any means such as optical fiber, wire, or visual means. Switching: selects the route to the desired destination that the transmitted signal travels by the closing of switches in either the space domain or the time domain or some combinations of the two.

Research and improve scheduling admission control mechanism to enhance QoS based on incoming burst rate prediction at core node to improve scheduling efficiency for low QoS bursts but still ensure a level of service quality for high QoS bursts. The effectiveness of the scheduling admission control mechanism was valued through simulation and mathematical analysis.

Research purpose: to build an analytical model representing the cross Kerr nonlinear coefficient of a four-energy quantum system in the inverse Y configuration in the presence of the Doppler effect. Apply the analytical results to the case of 87Rb at room temperature. Studying the ability to control and enhance the cross Kerr nonlinearity according to the parameters of the associated laser field and the temperature of the environment.

Practical TCP/IP and Ethernet Networking- P65: The transmitter encodes the information into a suitable form to be transmitted over the communications channel. The communications channel moves this signal as electromagnetic energy from the source to one or more destination receivers. The channel may convert this energy from one form to another, such as electrical to optical signals, whilst maintaining the integrity of the information so the recipient can understand the message sent by the transmitter....
