Military Network Topology (Indonesian Theatre)

Introduction

The military network topology described in this page is based on the topology of major U.S. and Indonesian commercial ISPs. It is a router-level network topology we come up with only for simulation purposes, using calculated IP addresses.

The backbone of the network consists of 6 major US ISPs (taken from the RocketFuel project at University of Washington). The 6 ISPs are Sprint (AS 1239), Verio (AS 2914), Level3 (AS 3356), Exodus (AS 3967), AboveNet (AS 6461), and AT&T WorldNet (AS 7018). The backbone contains 2978 routers, among which 307 are BGP speakers located at various exchange points.

The 6 ISPs are used to represent the top 2 levels of a military AS topology, The 6 ASes are interconnected as a clique. Other military ASes are attached to the backbone as tier-2 ASes, tier-3 ASes, and so on, maintaining their provider-customer relationships. There are a total 77 US military ASes included in this topology. To make extensions to the Indonesian backbone network, we added another 26 ASes: 21 of them are Indonesian ISPs and the rest are used to connect the network back to the US backbone.

We randomly choose 162 military bases out of the 682 bases discovered by UCR. These bases belong to different ASes according to the discovery, and we attach each base to a router in the designated AS that is geographically closest to the base. We also added 26 local area network to the Indonesian backbone. Each of the 162 bases and the 26 LANs is represented as a single router with a distinct AS number. We can attached different LAN models to represent the bases and LANs, but we do not include them in this topology.

In summary, this network contains 77+26=103 ASes as the backbone of the US and Indonesian networks. We added 162+26=188 LANs, each having its own AS number and containing only one router. In total the network has 291 ASes, 3279 routers (608 of them are BGP speakers), and 11952 links.
