Control and data link association..

[Abhimanyu Das <adas@mahinetworks.com>]

   I had a question relating to control-link data-link associations in
GMPLS. Is there an apriori association of data channels to specific control
channels on a given node? Suppose two nodes have a single data link between
them, but they have multiple IP control channels betwen them. Is there a
requirement from a protocol perspective at a node, to specify and use only
one particular IP control channel  for the given data link, so that, for
example, all signaling traffic related to that data link must travel over
the specified control channel only? Or is it the case that control packets
for the particular data link could be routed over any of the control
channels between the two nodes, as long as the control packets reach the
neighboring node..

Thanks,
