Dynamic optical mesh networks: Drivers, challenges and solutions for the future

Abstract: We discuss the scalability challenges facing the optical networks. Using the architecture based on spectrum-sliced elastic optical path network (SLICE), we demonstrate how the networking functionality can be effectively shifted to the optical domain.

Spectrum allocation policy modeling for elastic optical networks

Abstract: Today, optical transmission technologies are able to support 400Gbps over a single optical channel. However, this capacity cannot fit in the current fixed frequency grid optical spectrum. On the other hand, high rate optical channels have to co-exist with different ranges of line rates in order to serve heterogeneous bandwidth requests from variety of internet applications. Today's fixed rate and rigid frequency grid optical transmission systems cause over provisioning, where usually more spectral resources are provided than necessary.

Challenges for MPLS in optical network restoration

Abstract: Previous standards proposals have focused on extending IP-based MPLS protocols to optical networks. These proposals have concentrated on provisioning optical connections. However, a key expectation of the optical network is that it will offer fast restoration capability, competitive in performance to SONET rings. To meet this expectation, there are key features that need to be added to the current proposals to extend MPLS for the optical network. This article discusses some of these key requirements.

Elastic Optical Networking: Roles and Benefits in Beyond 100-Gb/s Era

Abstract: Emerging technologies such as spectrally efficient multicarrier higher order modulation and bandwidth variable wavelength selective switches have led to a change in the optical network architecture from rigid and homogeneous to flexible and heterogeneous in terms of the bit rate, center frequency spacing, modulation format, and optical reach. The elastic optical network (EON) is a network architecture toward beyond the 100-Gb/s era. This tutorial paper reviews elastic opticalnetworking technology and presents its roles and benefits in a new era, where major line rates in metro/core optical networks are 100 Gb/s and beyond. The main features of the EON are that it increases the spectral efficiency in a network manner through rate-adaptive superchannels and distance-adaptive modulation, and it provides cost- and energy-efficient traffic grooming in the optical domain. The EON concept has been widely accepted by industry and academia. Significant standardization efforts have yielded great advances evidenced by the flexible grid and the flexible OTUCn frame format recommendations. Hardware virtualization such as a sliceable multiflow transponder in cooperation with emerging flexible clients will be key to achieving more flexible and cost-effective next generation optical networks.
