  1. Optical Edge / Access Networks for GENI Lokesh Mandvekar lsm5@cse.buffalo.edu Dr. Chunming Qiao (PI)‏ qiao@computer.org Department of Computer Science and Engineering University at Buffalo (SUNY)‏

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

  3. 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

  4. 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

  5. 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)‏

  6. 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

  7. UB North Campus UB South Campus Fibers in Black Property of University at Buffalo UB Downtown Campus

  8. 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

  9. 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

  10. GENI backbone High Level Functional Architecture

  11. ACKNOWLEDGMENT • We acknowledge the support from • NEC Labs of America • UB CIT • and others who have provided useful discussions

  12. THANK YOU
