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 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

4
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

5
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

6
Summary

• Big picture
• IP-centric control planes
• Extended routing signaling protocols used to
  set up, modify, and release lightpaths
  dynamically gt inter-layer 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
