About using LMP for Address translation

[Amit 70405 <AmitG@huawei.com>]

HI All,
	Looking at the current discussion on Addressing I am bit confused about the Addressing in GMPLS.
	
	According to me in out-of-band signaling, RSVP messages should be double IP encapsulated with destination the as the data next hop TE router id.
	
	Below are the steps involved in signaling:

	- When a PATH message is received with a ERO(containing data plane hops) the outgoing PATH message should be double IP encapsulated.
	The top IP header destination should be TE router Id of the data next hop.

	- The data next hop TE router ID can be obtained by resolving the data hop in the ER0. This can be done by using TEDB.

	- Once the TE Router ID has been determined, the RSVP message can be sent out (based on the routing table entry for the data next hop TE Router ID) through the control channel.


	If LMP is used for resolving the translation from data plane address to Control plane address, ther has to be a 1:1 correspondance between control & data Plane.

	If the translation is done based on the Routing table as I mentioned above, there need not be any 1:1 correspondance.

	Plz let me know your views on this.

Thanks and Regards,
Amit.
