Ossified or fragile?
One group forgot to turn off an experiment
- after 2 weeks of router being pinged every 2 seconds, ISP contacted ISI and threatened to shut them down.
One group failed to initialize destination address and ports (and had many virtual nodes on each of many physical nodes)
- worked OK when tested on a LAN
- trashed flow-caches in routers
- probably generated a lot of unreachable destination traffic
- triggered port-scan alarms at ISPs (port 0)
- n^2 probe packets trigger other alarms
