The performance analysis tasks were conducted in three stages: call route analysis, traffic flow analysis and network performance analysis. The call route analysis was to determine if the routes from the edge switch to the core switch took the optimal path. This analysis revealed several sub-optimal routes for the IISP protocol configuration. The traffic flow analysis is based on the need for traffic to flow from one ELAN to another ELAN through a virtual router. The analysis showed that several routes require additional hops to reach their respective primary and secondary routers. The performance analysis was conducted using the data collected through the SNMP management system for a two month period. By using several statistical analytical methods, the high utilization segments in the edge networks as well as in the core networks were identified. The results showed that the LAN segment can accommodate two times more bandwidth for the currently shared network users, and can accommodate 50% more traffic when these users are migrated to the switched ports. For outer cores, the current utilization remained at 20%, i.e., four times more than the current traffic can be handled. Finally, the inner core traffic stayed at about 16% of the network utilization for 80% of the time. This analysis demonstrated a systematic method of demonstrating current network utilization to the network manager for current network operation and future growth planning.","PeriodicalId":266412,"journal":{"name":"IEEE ATM Workshop '99 Proceedings (Cat.

Leon-Garcia","doi":"10.1109/ATM.1999.786851","DOIUrl":"https://doi.org/10.1109/ATM.1999.786851","url":null,"abstract":"VC merging allows VC to be mapped onto the same VC label. It provides a scalable solution for network growth. It enables features such as stream merging in MPLS and RSVP wildcard filter to be efficiently supported over ATM. It also plays an important role in providing multipoint-to-multipoint multicast and share-tree multicasting paradigm. VC merging involves distinguishing cells from an identical merged VC label. Various approaches have been proposed to help this identification process. However, most of them incur additional buffering, protocol overhead and/or variable delay. They make the provision of QoS difficult to achieve. In this paper, we propose a novel merge-capable scheduler to support VC merging. The proposed scheduler consists of a core scheduler and a number of sub-queue sequencers forming a 2-level hierarchical structure. Using the proposed merge-capable scheduler, we can uniquely identify incoming cells while: (1) allowing cell cut-through forwarding and interleaving; (2) maintaining per-flow QoS; and (3) requiring no additional buffer and protocol overhead. We show analytically that the scheduler can guarantee a worst-case fairness and deliver a worst-case delay bound. We further analyze the scheduler performance in term of the service received by a queue and the average queuing delay experienced by a cell. The results indicate that the amount of services is fairly distributed among merging and non-merging flows according to their reservations. Moreover, the proposed merge-capable scheduler performs equally as well as its non-merging counterpart when reservations are highly utilized, even though it may introduce a minimal additional delay when utilization is low.","PeriodicalId":266412,"journal":{"name":"IEEE ATM Workshop '99 Proceedings (Cat.

An alternative proposal was made by Addie et al. (1998). The authors argued that because the central limit theorem can be applied to heavy traffic processes, therefore as more traffic is aggregated together through the sharing of a transmission link, the aggregated traffic will weakly converge to a Gaussian process. In this paper, we apply this Gaussian model to the connection admission control (CAC) of a multiservice network. We consider a store-and-forward (packet or cell-switched) connection-oriented multiservice network that can be based on the concept of asynchronous transfer mode. We also make efficiency comparison with a CAC based on an effective bandwidth model. Two scenarios were considered: the first assumes that all a priori traffic specifications are known before a CAC acceptance/rejection decision is made, while the second assumes that only the peak rate of a new (requesting admission) connection is declared to the CAC mechanism. The latter scenario entails a measurement-based CAC approach.","PeriodicalId":266412,"journal":{"name":"IEEE ATM Workshop '99 Proceedings (Cat.
