Re: the path

A path is essentially a potential node.

It is a location on a that may or may not actually talk to a node on a 
specific model.

A Path can be converted into either an array of unsigned integers or a 
string. The string form is a list of numbers separated by a colon. Each 
number refers to the offset at that level. The path "0" refers to the 
root node and the path "2:6" refers to the fifth child of the third node.

Virtual Trees are source-rooted trees in ATM networks in which VCs 
originating at the source but going to different destinations share some 
of the bandwidth pre-allocated to the VT, thus providing an additional 
advantage over Virtual Paths. Non-ATM protocols such as MIL-STD188 -220A 
can also take advantage of Virtual Trees source concatenation provides a 
benefit similar to ATM multiplexing. We describe the results of a 
simulation study which shows Virtual Trees.
