[e2e] Survivability

[Fernando Gont]

Hi,

In David Clark's "The Design Philosophy of the DARPA Internet protocols", 
the author says:

"Despite the fact that survivability is the first goal in the list, it is 
still second to the top level goal of interconnection of existing networks. 
A more survivable technology might have resulted from a single multimedia 
network design".

A few questions about this:

If the Internet protocol suite was developed by the DARPA, with military 
objetives, why was some survivability sacrified in order to be able to 
interconnect *existing* networks?  I mean, why didn't the "single 
multimedia network design" idea succeed?

If somehow it was thought that the Internet would be used, at some point, 
for commercial activity, why was "accountability" (for example) *last* in 
the list of goals?
