Doubt in LMP

Hi,

	When is the  evdcDown event generated in data link
	FSM. Is it when the channel status mesg arrive,
	but is it not the channel status message is used
	when the data link is allocated?

thanks,
Chaya

	Title		: Crankback Routing Extensions for MPLS Signaling
	Author(s)	: A. Iwata, N. Fujita, G. Ash, 
                          A. Farrel, S. Marshall-Unitt
	Filename	: draft-iwata-mpls-crankback-04.txt
	Pages		: 32
	Date		: 28-Jun-02
	
This draft proposes crankback routing extensions for CR-
LDP signaling and for RSVP-TE signaling.
Recently, several routing protocol extensions for
advertising resource information in addition to topology
information have been proposed for use in distributed
constraint-based routing.  In such a distributed routing
environment, however, the information used to compute a
constraint-based path may be out of date.  This means
that LSP setup requests may be blocked by links or nodes
without sufficient resources.
This draft specifies crankback routing extensions for CR-
LDP and RSVP-TE so that the label request can be retried
on an alternate path that detours around the blocked link
or node upon a setup failure.

	Title		: Multilayer routing using multilayer switch capable 
                          LSRs

The integration of multilayer switching capabilities within one 
box, such as the packet-switch capability (PSC) and the lambda-
switch capability (LSC) under the MPLS/Generalized-MPLS control 
mechanism, paves the way for achieving network resource optimization 
considering multilayer routing. This document clarifies the model of 
the GMPLS-controlled integrated PSC/LSC label switch router (LSR) 
and discusses the requirements of the routing extensions needed to 
achieve optimized multilayer traffic engineering.

Multi-layer path control

Hi folks,

I feel that GMPLS opens a new direction for multi-layer path network control and the topic should be
addressed in the CCAMP. Traffic engineering in multi-layer networks is a promising application. I
posted the following I-D on traffic engineering in multi-layer networks. Comments and feedbacks are
highly appreciated.

Kind regards

This draft proposes a traffic engineering framework for multi-layer path
networks using dynamic virtual topology configuration capability of
GMPLS protocols.  The electrical label switched path is routed over the
virtual topology built on a set of optical label switched path in multi-
layer path networks.  The virtual topology is dynamically altered by
setting up or tearing down optical label switched paths.  Virtual topol-
ogy is configured in response to traffic demand change so that conges-
tion of the network is mitigated.  Utilization of label switched path is

Hi, all.

  We have updated our routing draft attached below.
  We've recognized that interface switching capability descriptor (ISCD) 
being defined in routing protocols
lacks functionality in order to properly operate multilayer LSRs with 
LSC+PSC, LSC+DXC+PSC, and so on.
  So, we want to add definition of new interface descriptor called 
"interface adaptation capability descriptor".

  Background and aim of this proposal is to realize of multilayer routing 
domain which tunnels any kind of LSPs using the multilayer LSR.
  However, the proposed ISCD in this stage cannot properly express the LSP 
termination capability
in each multilayer LSR.
  I think this problems is very common especially in circuit switch capable 
such as LSC and DXC.
  In some case, these switches can have different capability between LSP 
forwarding capability and termination
capability. We already encountered this kind of problems in routing 
calculation of O-LSP.
  For example, a PXC-LSR can provide forwarding capability for any kind of 
O-LSPs, but termination capability
depends on the adaptation functionality attached to the PXC. But, the ISCD 
cannot effectively express such constraints for routing calculation.

  I'm happy and appreciate if we could share the problems I mentioned, and

	Title		: Link Management Protocol (LMP)

	Date		: 02-Jul-02
	
Optical networks are being developed to include photonic switches, 
optical crossconnects, and routers that are configured with control 
channels and data links. Furthermore, multiple data links may be 
combined to form a single traffic engineering (TE) link for routing 
purposes. This draft specifies a link management protocol (LMP) that 
runs between neighboring nodes and is used to manage TE links. 
Specifically, LMP will be used to maintain control channel 
connectivity, verify the physical connectivity of the data-bearing 
channels, correlate the link property information, suppress 
downstream alarms, and localize link failures for 
protection/restoration purposes in both opaque and transparent 
networks.
