A New SDH Traffic Model for W-DCS Performance Evaluation
نویسنده
چکیده
Digital Cross-Connect System (DCS), used for distributing and crossconnecting the synchronous optical and asynchronous electrical signals, plays very important role as transmission equipment in the transport networks, is The performance evaluation of the switch matrix of the DCS by simulation methods will require a realistic traffic model generating practical connection and disconnection demands. In this paper, a realistic and reliable model for SDH traffic for wideband DCS will be proposed. This traffic model generates traffic such as STM-1 (Synchronous Transport Module level-1) synchronous signal and DS-3, DS-1E, DS-1 asynchronous signals. In addition to the signal generations, three different connection types (unidirectional unicast, bidirectional unicast, and multicast) can be generated by the model. The goal of the traffic model is to generate connection and disconnection demands satisfying given traffic loads.

To enable the transference of a large amount of data over long distances, it is required to use infra-structures denominated transport networks. This work is about NextGeneration Synchronous Digital Hierarchy (NG-SDH) transport networks, which result from the convergence between SDH networks and Ethernet networks. The changes introduced into the legacy SDH are studied, and a set of heuristic al...

متن کاملDeveloping a Model of Heterogeneity in Driver’s Behavior
Intelligent Driver Model (IDM) is a well-known microscopic model of traffic flow within the traffic engineering societies. While it is a powerful technique for modeling traffic flows, the Intelligent Driver Model lacks the potential of accommodating the notion of drivers’ heterogeneous behavior whenever they are on roads. Concerning the above mentioned, this paper takes the lane to recognize th...
