Manuscript: CL 2002-1133 Generating Realistic ISP-Level Network Topologies
نویسندگان
چکیده
Simulations are an important tool in network research. As the selected topology often influences the outcome of the simulation, realistic topologies are needed to produce realistic simulation results. Using several similarity metrics to compare artificially generated topologies with real world topologies this letter gives hints how to use the wide-spread topology generators BRITE, TIERS and GT-ITM to create realistic topologies.

Analyzing and Modeling Router-Level Internet Topology
Measurement studies on the Internet topology show that connectivities of nodes exhibit power–law attribute, but it is apparent that only the degree distribution does not determine the network structure, and especially true when we study the network–related control like routing control. In this paper, we first reveal structures of the router–level topologies using the working ISP networks, which...

متن کاملGenerating Representative ISP Technologies From First-Principles
Understanding and modeling the factors that underlie the growth and evolution of network topologies are basic questions that impact capacity planning, forecasting, and protocol research. Early topology generation work focused on generating network-wide connectivity maps, either at the AS-level or the router-level, typically with an eye towards reproducing abstract properties of observed topolog...
متن کاملFeasibility Aspects of AMP Performance Evaluation in a Fluid Simulation Environment
In order to address the problem of intra-domain IP traffic engineering efficiently, we have recently proposed Adaptive Multi-Path routing (AMP) as a dynamic algorithmic solution based on a local view of the network. For two real ISP topologies we have demonstrated that our scheme significantly improves network performance while generating only minimal signaling overhead. However, our performanc...
متن کاملAnalyzing network bandwidths of ISP topologies having power-law degree distributions
Recent measurement studies on Internet topology show that the connectivities of nodes exhibit a power–law attribute. That is, the probability p(k) that a node is connected to k other nodes follows p(k) ∼ k −γ. However, even if the degree distributions of some topologies are the same, more detailed characteristics are often quite different. For example, ISP topologies had a much higher cluster c...
