Hello,

I hope this list is still alive...

Sorry if my question is too dumb, but after reading
RFC 2205 & 2209 several times, I still don't understand this:

1 - Does entering a 'blockade state' mean freeing the allocated
resources?

Let me have an example:

    +--+   B:4  +--+   B:4  +--+
...-|R1|--------+R2+--------|R3|-...
    +--+        +--*        +--+
                    \
                   2 \
                      \
                       +--+
                       |R4|-...
                       +--+

Here the R2-R1 interface of the router R2 has totally
4 units of resources. Now a RESV(4 untis) coming from 
R3 is rejected at R1, and thus gets blocaded in R2, too.
Afterwards a new RESV(2 units) **belonging to a 
different session** is coming from R4 towards
R1 hits R2. Will this be accepted at R2 or will it be rejected?

2 - What will happen between the endpoint, whose RESV is rejected, 
and the first router, who has now a blockade state?

If the endpoint re-sends the same RESV, will it be denied 
automatically, while the blocakde state is alive?

Thanks a lot,
Krisztian
