-------------------------------
Hi [~Naganarasimha Garla] [~gp.leftnoteasy]
I have one comment here.
bq. if exception raise when replace labels on node, put the new labels
I assume current idea is in such a way that if one label from NM is found as
invalid, complete labels sent by NM in that heartbeat will be considered as
error.
Could it be done in such a way that, give a number of labels from NM as 5 at a
given heartbeat. In that 2 labels are found to be invalid by RM. If so, why
could we accept the 3 passed labels, and send back 2 rejected labels back to
NM. This may make the work better and easier to handle.
How do you feel?
