Up: 4 VNET: A simple
Previous: 4.3 Interface
Our goal for VNET was to make it easy to convey the network management
problem induced by VMs to the home network of the user where it can
be dealt with using familiar techniques. However, it is important
that VNET's overhead not be prohibitively high, certainly not in the
wide area. From the strongest to the weakest goal, VNET's
performance should be
We have found that our implementation meets the later two goals, and,
in many cases, meets the first, strongest goal as well.
- in line with what the physical network is
- comparable to other networking solutions that don't address the
network management problem, and
- sufficient for the applications and scenarios where it is used.
