QoSR and reservation

[costas s. <c_s...@ya...>]

Hi,

I looked the example qosr.tcl, and i was thinking if
it is possible to implement elastic reservations.
Specifically, I mean, whenever QOSPF do an update and
a better route exit to trigger an update also in the
reseavation of the path and recompute the eroute. For
example,

                          n1
                         /  \
                    5Mb /    \ 5Mb 
                       /      \    
                      /  2Mb   \   
                    n0----------n2 


1. a 2.5 Mbps session between n0 and n2 fid 1 (path
taken n0-n1-n2)
2. a 1.5 Mbps session between n0 and n2 fid 2 (path
taken n0-n2)
3. a 1.5 Mbps session between n0 and n2 fid 3 (path
taken n0-n1-n2)
4. a 3.0 Mbps session between n0 and n2 fid 4
(unsuccessful as bandwith not available so forwarded
as best-effort fid 0) 

If fid 1 and fid 2 stop after 2.0sec, fid 4 which was
unsuccessful so far, to be able to make a new
reservation in the path n0-n1-n2 after the 2.0secs
