• Distributed Network Simulations Using the Dynamic Simulation Backplane 

      Riley, George F.; Ammar, Mostafa H. (Mostafa Hamed); Fujimoto, Richard M.; Xu, Donghua; Perumalla, Kalyan S. (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, Inc., New York, 2001-04)
      Presents an approach for creating distributed, component-based simulations of communication networks by interconnecting models of sub-networks drawn from different network simulation packages. This approach supports the ...
    • Enabling Large-Scale Multicast Simulation by Reducing Memory Requirements 

      Xu, Donghua; Riley, George F.; Ammar, Mostafa H. (Mostafa Hamed); Fujimoto, Richard M. (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, Inc., New York, 2003-06)
      The simulation of large–scale multicast networks often requires a significant amount of memory that can easily exceed the capacity of current computers, both because of the inherently large amount of state necessary to ...
    • Large–Scale Simulation Models of BGP 

      Dimitropoulos, Christos Xenofontas A.; Riley, George F. (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, Inc., New York, 2004-10)
      The complex nature of the Border Gateway Protocol (BGP) is not amenable to analytical modeling, and thus simulation–based analysis methods are needed to understand its behavior. To this end, we investigate techniques that ...
    • On Standardized Network Topologies For Network Resesrch 

      Riley, George F. (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, Inc., New York, 2002-12)
      Simulation has become the evaluation method of choice for many areas of computer networking research. When designing new or revised transport protocols, queuing methods, routing protocols, (just to name a few), a common ...
    • Scalable RTI-Based Parallel Simulation of Networks 

      Perumalla, Kalyan S.; Park, Alfred; Fujimoto, Richard M.; Riley, George F. (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, Inc., New York, 2003-06)
      Federated simulation interfaces such as the High Level Architecture (HLA) were designed for interoperability, and as such are not traditionally associated with high performance computing. In this paper, we present ...
    • Simulating Internet Worms 

      Riley, George F.; Sharif, Monirul I.; Lee, Wenke (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, Inc., New York, 2004-10)
      The accurate and efficient modeling of Internet worms is a particularly challenging task for network simulation tools. The atypical and aggressive behavior of these worms can easily consume excessive resources, both ...
    • Stateless Routing in Network Simulations 

      Riley, George F.; Ammar, Mostafa H. (Mostafa Hamed); Fujimoto, Richard M. (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, Inc., New York, 2000)
      The memory resources required by network simulations can grow quadratically with size of the simulated network. In simulations that use routing tables at each node to perform per-hop packet forwarding, the storage ...
