[j-nsp] Load Balance b/w two or more LSPs

[Arda Balkanay]

Hi
To load balance, as a knob you can play with some CoS.
You can change the forwarding-class with a policer if some bw-limit is
exceeded. This changes the EXP field of the label and can help you to get a
different hash. with two hashes you have a chance to use secondary path.
Kind Regards
Arda
