To Artifact [96dbfc402b]:

• File script.txt — part of check-in [9d4ecbd82b] at 2012-09-26 21:50:08 on branch trunk — Go from rD to experiments support title slide instead of node arch overview. (user: ivan, size: 11127) [annotate] [blame] [check-ins using]

   132    132       - uses traffic control, filtering and anonymization to ensure network
   133    133         stability, isolation and privacy (partialy implemented). *##*
   134    134   - The recovery device (not implemented) can force a remote hardware reboot of
   135    135     the RD in case it hangs.  It also helps with upgrade and recovery. *##*

   139    138   Researchers can configure slivers with different types of network interfaces
   140    139   depending on the connectivity needs of experiments.  For instance, to *##*

   142    141   - mimic a home PC: use the private interface, *##* which has L3 traffic
   143    142     forwarded using NAT to the CN but filtered to ensure network stability. *##*
   144    143   - implement a network service: create a public interface, *##* which has a CN
   145    144     address and L3 traffic routed directly to the CN but filtered to ensure
