Abstract

Emerging Metro Ethernets create new opportunities to converge data and telephony services. However, to connect legacy telephony equipment, networks have to meet customary QoS requirements even at the presence of bursty data cross traffic. We show with analytical evaluation and simulation results that without appropriate mechanisms the QoS requirements cannot be met.
