Role of Control Plane Advances in the Creation of Flexible Transport Networks Vijay Vusirikala, Infinera
DWDM Digital Bandwidth Management • Photonic integration enabled 100Gb/s line cards • Digital PMs and OAMP • Digital wrapper for multi-service support • Sub- add/drop, switching and grooming • Digital protection • Multi-way junction node switching GMPLS • Automated equipment and topology discovery • End-to-end circuit routing and provisioning • Bandwidth efficient restoration • Dynamic “Bandwidth-on-Demand” GMPLS in Digital Optical Networks
End-to-end data plane continuity enables fully automated operational model Any service at any node Service layer decoupled from transmission layer Digital Electronics & Software Integrated Photonics Integrated Photonics • Sub- add/drop • Digital switching • Signal regeneration • Digital Protection • Digital OAMP GMPLS in Digital Optical Networks Truly unconstrained reconfigurable optical networking
GMPLS in All-Optical ROADMManual OEO Touch Points Limit GMPLS Benefits • Intermediate manual OEO touch points limit end-to-end automated operational model • Muxponders for aggregating sub- services • Regen transponders for reach limitations • Wavelength converters to overcome wavelength blocking • Service paths coupled to transmission layer design constraints • Results in limited protection and restoration options New A-Z demand 8 x 1G 1G 1G Regeneration Wavelength conversion
? ? ? GMPLS in OXC + Static DWDM Architecture • Benefits of GMPLS control plane limited to switching layer • Common management views and end-end control plane intelligence need additional integration effort • No sub- switching, grooming or protection at intermediate degree-2 OADM sites
