Multi-layer Recovery Data (INFOCOM 2005):

• GT-ITM topology generator modifications to handle overlay layer [sgb2ns.c | ns-rtProtoLS.tcl | ns-node.tcl]
• Sample TCL file that simulates Dual rerouting over the generated topology [dualRerouting.tcl]
• ns2 modifications to simulate Dual rerouting [ls.cc | ls.h | rtProtoLS.cc | rtProtoLS.h]
• ns2 modifications to create overlay topology [tcl/lib/ns-node.tcl | tcl/rtglib/ns-rtProtoLS.tcl]
• Script to process output of the above NS2 simulation [processOutput.tcl]

Overlay Violations Data (ICNP 2006, GLOBECOM 2007):

• List of 58 Planetlab nodes used [siteList.txt]
• Overlay link info summary (Format: Src / Dest / Hop count / Latency) [linkSummary.txt]
• AS-path of each overlay link (Format: Src / Dest / AS path) [linkASPath.txt]
• AS relationships obtained by using a corrected Gao's algorithm, for the inter-AS links we observed [asRelMap.txt]
• Implementation of shortest path algorithm [shortestPath.cc | shortestPath.h]
• Overlay paths generated by latency-based SPF (Format: Src / Dest / NextHop / PathLatency / ActualPath) [latencyCalculation.txt]
• Contact me for actual rockettrace / traceroute info (or) other AS-level information.
