Routing in Large Communication Networks

The complexity (number of entities, interactions between entities,
and resulting emergent dynamic behavior) of large communication
environments which contain hundreds of nodes and links
make simulation an important tool for the study of such systems.
Given the difficulties associated with
complete analytical treatment of complex dynamical systems, it is
often the only
practical tool that is available.
This paper presents an example of a
flexible, modular, object-oriented toolbox
designed to support modeling and experimental analysis
of a large family of
representation and decision functions for adaptive self-managing
communication networks with particular emphasis on routing strategies.
It discusses in detail, the design,
implementation, and validation
of the toolbox using the discrete event simulation paradigm.
It addresses several major practical design
challenges presented by potentially large
computational time and memory
requirements of simulation of large communication networks and describes
novel solutions adapted from the simulation and performance
modeling and analysis literature to meet such challenges. It also
examines some issues that arise in the validation of the resulting
object-oriented simulation and modeling toolbox.
