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
PASSIVE OPTICAL NETWORKSA 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
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)
EXISTING FACILITIESBasic 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
Fibers in Black Property of
University at Buffalo

UB Downtown Campus
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
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
