Advanced IP/MPLS and Optical Networks:
Concepts and Standard
The suite of protocols that defines Multi-Protocol Label Switching (MPLS) has been enhanced to generalize its applicability to the control of optical networks, with one area of prime consideration being the use of these generalized MPLS protocols
in upgrading the control plane of optical networks. A major advantage of the MPLS architecture for use as a general network control plane is its clear separation between the data forwarding plane, the signaling (connection control) plane, and the routing
(topology discovery/resource status) plane.
A through understanding of MPLS technology, the issues involved in using it to control optical networks, and the protocol and system enhancements needed to enable this is crucial for building advanced transport and hybrid packet/TDM systems, and for building modern transport networks.
With this goal, this workshop covers:
- MPLS technology: Brief introduction, operation, and advantages
- Agile optical networks: motivation and basic concepts
- Control plane architectures and system design trade-offs: possible architectures for the control plane, their pros and cons
- Differences between datagram and optical routing: service impact, standardization
- MPLS control plane for non-packet technologies: Enhancements to IP routing (OSPF) and signaling (RSVP-TE) , how that impacts system and network operation
- Overview of optical control plane standards: discovery, intra-domain routing, signaling, and inter-domain routing, and the UNI (User-Network Interface), with a look at work ongoing at the ITU, IETF, and OIF.
- Dynamic path establishment in multi-layer networks: issues and operation
