Our Proposal – “GENI Cinema”
• A persistent live video streaming service over GENI
– Anyone can stream live audio/video media “towards” GENI
– Anyone can search, select, view live media “from” GENI

A GENI Solicitation 4 Project
• To create a persistent GENI experiment that
– is ALWAYS ON for research …… and education
• Education - Not just about network education
– Utilizes SDN, compute, instrumentation & measurement
• Exploit full potential of GENI, and beyond GENI
– captures entire network architecture, edge-to-core
• Apply our existing research solutions
– offers service as incentive for community-driven scale-up
• Get help to achieve at-scale experimentation with opt-ins
• Make GENI and SDN relevant to more communities
– connect students to open source software community
• Build upon existing open source projects

Our Proposal – “GENI Cinema”
• A persistent live video streaming service over GENI
– Anyone can stream live media (A/V) “towards” GENI
– Anyone can search, select, view live media “from” GENI

Key Components & How It Works
• GENI Cinema Gateways
– Web server with published IP address for
selecting/configuring stream (upstream or downstream)
– Multiple available, e.g., one per participating campus
– With OpenFlow, streams need not bottleneck at gateway,
can direct to different relays over different paths
• GENI Cinema Server/Relays
– Streaming server + relay
– Performs network coding and multicast
• OpenFlow Network: Switches + Controller(s)
• Access from any network (openflow or not)

Opt-in Users/Campuses & Collaborators
• Campus Sites as GENI Cinema Endpoints
– Video streaming from seminar halls
• Existing education streaming sources
– Both live and archived sources can be great
• Video streaming platform experts
– We can code, but we are networking researchers 
• Web front end experts
– We’d love to adopt platforms that enhances user’s
interactive experiences!
All Suggestions are Welcome!
