RE: Question on LMP

[Martin Dubuc <martin.dubuc@edgeflow.com>]

George,

I have heard that in the upcoming version of LMP draft, there won't be any
Control Channel Id field in the LinkSummary message.

This change was requested because there is no one-to-one association between
TE links and individual control channels in version 02 of LMP. All control
channels between a node pair manage all TE links between the same node pair
at the same level. LinkSummary message for a TE link could be sent on any of
the control channels. As such, the Control Channel Id field in the
LinkSummary message is not as much required.

If one can rely on the source IP address of the LMP message to identify the
originator of the message - given that it is easy to map the source IP
address to the Node ID, then this should solve the problem. However,
thinking about it some more, I am not sure this assumption is right.

Any comments on that Jonathan?

Martin

Hello Sudheer,

The Config and ConfigAck Messages contain a Node ID which allows correlation
with the Control Channel Id.

Regards,
George.

I have a small question/clarification needed on LMP...

How does the LMP determine from where the (Link summary etc.)
packets are received if the remote CCId or local source IP
address is not part of the LMP packets?

THank you for the help.
