SUMMARY: 2 NICs as one with double speed

["Ezequiel H. Panepucci" <zac@xxxxxxxxxxxxxxxxxxxx>]

Hi People,

Tru64 is _not_ able to load balance network traffic
over 2 or more NICs. What a pity...

Workarounds were suggested:

1) Split services yourself over the 2 NICs
2) Using a good router (see Robert Carsey)

NetRain is a feature that enables for network
failover capabilities.

Thank you for your prompt attention.

Zac
