Teletraffic Engineering Model for IP Networks

One of the basic tasks of traffic engineering is the effective adaptation of services, link capacity and routing scheme to achieve good performance (from the user's view) and efficient use of network resources. In our paper we describe the generalized model and practical approach to solving teletraffic and QoS problems in the Internet environment. We introduce three timescales in problem decomposition: data timescale (individual packet level), control timescale (traffic flows) and network management timescale (aggregates of flows). One real network problem is discussed and basic causses of quality-of-service problems are identified. Two clusters of Internet QoS problems (network related and others) are discussed. The choice of the routing solutions based on the broader view of network topology and teletraffic systems traits has several advantages which have to be considered.
