Quality of Service (QoS) has traditionally been used in connection-oriented ATM and Frame Relay networks to guarantee traffic delivery. In contrast, connectionless IP networks have addressed QoS by adding capacity as networks became congested. QoS mechanisms are required in MPLS-based networks to manage inevitable network congestion and guarantee applications sensitive to delay, jitter and packet loss. With QoS-enabled devices in MPLS networks, providers can offer differentiated services, guarantee bandwidth, increase control over network resources, classify and prioritize traffic and manage network congestion in networks that were previously limited to best-effort Internet service.
This session will provide an in-depth look at the fundamental issues QoS issues vendors must address and carriers require in MPLS networks including:
