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 Internet 2 / NLR via NYSERNet

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

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 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

UB North Campus UB South Campus 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 • Wi. MAX or other AP/BS technologies • Wireless Mesh Networks • Disruptive 4 G cellular with distributed MIMO

High Level Functional Architecture GENI backbone
