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constraint-based path may be out of date.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
Author(s) : W. Imajuku et al.
Filename : draft-imajuku-ml-routing-02.txt
Pages : 17
Date : 01-Jul-02
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.

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

Title : Multi-area multi-layer traffic engineering using
hierarchical LSPs in GMPLS networks
Author(s) : K. Shiomoto et al.
Filename : draft-shiomoto-ccamp-multiarea-te-01.txt
Pages : 10
Date : 25-Jun-02
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

[ post by non-subscriber. with the massive amount of spam, it is easy to miss and therefore delete mis-posts. so fix subscription addresses! ] 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(Continue reading)

A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the Common Control and Measurement Plane Working Group of the IETF. Title : Link Management Protocol (LMP) Author(s) : J. Lang Filename : draft-ietf-ccamp-lmp-04.txt Pages : 65 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.
