Is it not possible to require that each of your suppliers provide
over a specified path ? I'm planning a build-out that will require a
diverse path between two points, and one supplier has named two
routes, and promised that they wont change for the duration of the
contract. Perhaps I am naive, but a promise should be a promise.
Also instead of buying path A from supplier X and path B from
supplier Y, it might be worth buying paths A and B from supplier X
and a spare path B from supplier Y too. Supplier X must know they
only get dollar N because they can provide both paths.. and in
addition diversity has to matter more than money because you are in
effect paying for one path twice.
