Summary Summary

Summary • Bimodal optical & wireless networks – Goal of Internet & communications networks Summary • Bimodal optical & wireless networks – Goal of Internet & communications networks • Provide access to information when we need it, where we need it, and in whatever format we need it – Toward this end, optical & wireless networks play key role & can be viewed as quite complementary • Optical networks – Optical fiber does not go everywhere – Where it does go, it provides huge amount of bandwidth & exhibits advantageous transmission properties • Wireless networks – Potentially go almost everywhere & support mobility – Provide highly bandwidth-constrained transmission channel, susceptible to variety of impairments – Clearly, future communications will be bimodal

Summary • Historical review – Optical networks well suited to • Satisfy growing bandwidth Summary • Historical review – Optical networks well suited to • Satisfy growing bandwidth demands • Provide transparency & reliability • Simplify network operation & management – Optical networks have evolved from point-to-point links to powerful all-optical WDM networks providing • Arbitrary topology • Transparency • Reconfigurability • Survivability • Scalability • Modularity

Summary • Historical review – Management & control of reconfigurable optical networks are of Summary • Historical review – Management & control of reconfigurable optical networks are of utmost importance to make them commercially viable • Management – TMN framework » Encompasses wide range of standards covering management issues commonly known as FCAPS model • Control – Control plane » Responsible to control data plane by ensuring that various forwarding techniques operate properly & efficiently in each single optical network » Guarantee interoperability among multiple optical networks of different vendors & operators

Summary • Big picture – Optical switching networks • All types of flexible, resilient, Summary • Big picture – Optical switching networks • All types of flexible, resilient, and reconfigurable optical networks using various multiplexing, tuning, and switching techniques • Can be found at each network infrastructure hierarchy level • Offer many different switching granularities – – Fiber Waveband Wavelength Subwavelength (time slot, burst, packet, cell, frame) • Control plane typically operates at data link or network layer, with particular focus on IP-centric control planes

Summary • Big picture – IP-centric control planes • Extended routing & signaling protocols Summary • Big picture – IP-centric control planes • Extended routing & signaling protocols used to set up, modify, and release lightpaths dynamically => interlayer networking between electrical & optical layers – Also useful to address other issues such as security & grooming which are best done in electrical domain – Optical switching networks limited to islands of transparency exploiting respective strengths of optical & electronic technologies to reduce costs & improve performance – Future research on optical switching networks expected to shift to design of adaptive service shell for value creation, revenue growth, and realization of novel business strategies
