Hi,

I think the charter draft is fine. A minor comment is the followings:

l.4.
........... These resource can be network components, such as, for
example, routers, switches or hosts, and also services, such as, for  
example,
name mapping systems. .....

In the above, there is no "circuit" and "link" technology in the network
component type enumeration. I think it should be add, if it can be  
consists
of virtualized network.
