Why Another Simulator?
Fully Integrated Network Environment
- control over more than just BGP
- eg: TCP/IP, traffic, router & link hardware
- designed to handle large, complex simulations
- tens of thousands of multi-protocol nodes
Design Trade-off Toggles
- eg: tie-breaking in route selection
- eg: apply minAdver timer to withdrawals
Explore Impact of New Functionality
- before it goes live!
- eg: MPLS; protocol extensions
necessary for studying BGP on a large scale;
MRT and Zebra have their values tooóyou can install them and run them on a router; SSF.OS.BGP4 you canít
