  8. Optical Standards • Client Interfaces • Ethernet: 2xGbE, 8xGbE, 10G-WAN, 10G-LAN • SONET/SDH: 4xOC3/OC12, 1xOC48, 4xOC48, 1xOC192 (also STM equivalents) • ESCON: 1xESCON, 2xESCON, 12xESCON • FC/FICON: 1xFC, 2xFC, 1xFICON, 2xFICON • G.709: 1xOTU1, 1xOTU2 • SFP/XFP pluggable optics • Optical/Section PMs, RMON • Transmission Interfaces • 2R Transparent, 3R Transparent, optional PMs • OTU1, OTU2, optional FEC • External Wavelength, integrated VOA control • 40 lambda ITU-T grid DWDM (1530 – 1560nm) • 8 lambda CWDM support • Certifications • NEBS • OSMINE • RoHS

  9. GMPLS • Superset of MPLS • Identical concepts, mechanisms, protocols • IP-based, reuse existing stable/tested/battle-hardened protocols • Expands the concept of a “label” • In MPLS, a label ties a packet to a flow • In GMPLS, labels can identify TDM streams (SONET/SDH), Wavelengths (DWDM), Fibers (OXCs), as well as packet flows • Unified control of diverse network technologies • One set of concepts to learn, tools to deploy • LSPs, labels, signaling, routing, path computation • Manage different types of flows using single set of tools • Same provisioning methods for IP and optical networks • Lessons learned from MPLS deployments • Bidirectional LSP setup, support for out-of-band communications, etc

  10. Labels distributed between specific end-points Ingress initiates LSP Data flow 28 92 15 35 47 Tunnel LSP: Example • Request propagated to egress • Egress responds with label • Response propagated upstream to ingress

  11. Reuse of MPLS and IP Control Ingress initiates light path setup Data flow λ5 λ2 λ8 λ2 λ2 Controlled Light Path • Request propagated to egress • Egress responds with lambda • Response propagated upstream to ingress

  12. Control Plane Standards • Routing • RFC2328 (OSPF v2) • RFC3630 (OSPF-TE v2) • RFC4202 (GMPLS Routing) • RFC4203 (OSPF-GMPLS) • Signaling • RFC2205 (RSVP) • RFC3209 (RSVP-TE) • RFC3471 (GMPLS Signaling) • RFC3473 (RSVP-GMPLS) • In Progress • draft-ietf-ospf-ospfv3-traffic-06 • draft-ietf-ccamp-rsvp-restart-ext-05 • draft-ietf-ccamp-crankback-05 • draft-ietf-ccamp-gmpls-segment-recovery-02 • draft-ietf-ccamp-gmpls-recovery-e2e-signaling-03 • draft-ietf-ccamp-gmpls-alarm-spec-03 • draft-ietf-ccamp-gmpls-addressing-02 Mature, several interoperable implementations
