AGENDA

  • OBJECTIVES
  • PASSIVE OPTICAL NETWORKS
  • ADVANTAGES OF PON / GENI CONTRIBUTION
  • EXISTING FACILITIES
  • PROJECT MAPS
  • DELIVERABLES
  • INTEGRATED OPTICAL/WIRELESS ACCESS
  • ACKNOWLEDGMENT
slide3

OBJECTIVES

  • Building a campus / metro wide optical access network using PON technologies
  • GENI compatible hardware and software (programmability, virtualization support, scalability, etc.)
  • Interface with a GENI control framework
  • VLAN connections to Internet2 / NLR via NYSERNet
slide4

PASSIVE OPTICAL NETWORKS

  • A PON consists of a single shared optical fiber providing access to multiple subscribers via optical splitters
  • Typically, a tree architecture with 1 OLT(Optical Line Termination) serving multiple ONUs(Optical Networking Unit)
  • No active components in the network except at the endpoints
slide5

ADVANTAGES OF PON

  • & GENI CONTRIBUTION
  • High speed access, low bit error ratio, low cost, low maintenance
  • End-to-end protocol and coding format transparency
  • Better virtualization support at the physical layer (with WDM / OFDMA)‏
slide6

EXISTING FACILITIES

  • Basic infrastructure already in place – UB owns an extensive fiber network laid over Buffalo area
  • ONUs to be setup at research centers requiring high bandwidth connectivity and heavy computation

DELIVERABLES

  • Initially, a whitepaper describing
          • Software and hardware architecture of the PON testbed
          • Requirements and feasibility
          • Expected functionality, time and cost
          • GENI users and applications
slide10

INTEGRATED FIBER/WIRELESS ACCESS

  • Future plans to integrate optical and wireless access to facilitate advanced wireless experiments related to
          • WiMAX or other AP/BS technologies
          • Wireless Mesh Networks
          • Disruptive 4G cellular with distributed MIMO
