“NLR has deployed a combination of CRS-1s
and Cisco ONS 15454 platforms…The
integration of DWDM transponders simplifies
the network by reducing the number of
network elements, and enables rapid and

 GMPLS

Dynamic service activation
ƒ GMPLS Benefits
Optical elements become peers of
router elements
“Isocore has verified GMPLS
Auto-provisioning of lambda via IP on the CRS-1, XR 12000 and
Reduces opex 7600. Our test bed included all
of the major router vendors as
Speeds provisioning
well as all the major optical
Enhances alarm correlation vendors.”, Dr. Jabbari,
ISOCORE
ƒ GMPLS Deployment Challenges
No separation between router and optical domains
Exposes control of optical network to outsiders
Exposes optical topology to outsiders
