Multiprotocol label switching (MPLS)-based networks are gaining popularity with service providers because they retain the flexibility of Internet protocol (IP) while providing support for quality of service (QoS) through differentiated services (DiffServ). The deployment of such networks requires service providers to ensure that service-level agreements (SLAs) with their customers are being met while guaranteeing cost-effective utilization of their network. The key to achieving these objectives is an efficient monitoring system that tracks QoS metrics such as bandwidth utilization, delay, and packet loss. These metrics can be tracked at multiple granularities, such as per customer, per MPLS tunnel, and per physical network pipe. SEQUIN is a simple network management protocol (SNMP)-based monitoring system capable of tracking QoS metrics in near real time. Some of the challenges addressed by SEQUIN are synthesis of end-to-end QoS using polled data from different network elements, visualization of these metrics across the network, identification of performance problems by correlating the monitored parameters, and design of scalable polling strategies to minimize management traffic. © 2003 Lucent Technologies Inc. |
