Traffic generation algorithm for sdh digital cross‐connects
B. Johnston, Henry L. Owen · European Transactions on Telecommunications · 2002
Abstract Data in Synchronous Digital Hierarchy (SDH) networks may be routed, managed, and regulated bydigital cross‐connect systems(DCSs). The adequacy and performance of current and proposed DCSs are determined through simulations, which require realistic connection requests ortraffic.This work entailed the creation and analysis of a traffic generation algorithm for SDH DCSs. The algorithm accepts any valid configuration of desired traffic characteristics, and it produces connection and disconnection requests according to the provided configuration. The algorithm incorporates a probabilistic approach that allows the statistics of the configuration to determine the distributions of the types of connections and disconnections that are attempted. Special considerations are made to maintain the requested output load, to apportion the payloads, and to create opportunities for bidirectional connections. This paper includes an analysis of factors that may affect traffic generation.
