Hi,
I got some doubts.
Regarding my thesis, I would like to do something
that is new.
Then, I got an idea.
Considering fault-tolerance in MPLS,
We will always have back-up path for the current path.
If current path fails, the traffic is shifted onto the backup one.
Once restored the traffic is shifted back to the current one.
Now, this way the load oscillations will occur which is undesirable if =
the failure occurs frequently on the current one, since the probability =
will be higher to failure.
So, what if we can use the backup path as the main path, though
previous path is restored.
Now, the load oscillations will be less.
What is your idea on this.
Is this worth enough? or is this ridiculous?

Thank you very much,
Sincerely,
Ramachandra Bachala
