Fast Spanning Tree Reconnection (FSTR) is a newly proposed restoration method by us to handle single link failures in Metro Ethernet networks. Compared with other methods existing in the literature, FSTR has the advantages of lower signalling overhead, faster recovery and lesser rerouted traffic. In this work, we propose to use partial spatial protection (PSP) mechanism to provision differentiated...
Ethernet is becoming a preferred technology to be deployed in metro domain due to its low cost, simplicity and ubiquity. However, traditional spanning tree based Ethernet protocol does not meet the requirement for metro area networks in terms of network resilience. In the work of Qiu et al. (2009), we proposed a fast spanning tree reconnection (FSTR) mechanism for metro Ethernet networks to handle...
A 16bit audio SigmaDelta modulator is designed, with only 360 muw power dissipation under 0.9 V supply. A feedforward third-order single loop architecture is adopted to decrease the power dissipation. A novel double-boost switch is proposed in the design to decrease the on-resistance. A low power class-AB operational transconductance amplifier (OTA) with proposed self-adapted bias circuit is applied...
