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)

Objectives:• Direct access to I2

100G Innovation Platform

• Science DMZ from anywhere, w/o manual plumbing

• Campus production,end-to-end support

• Flexible, optimized10~40G access to resources on campus and other universities

• Software defined network (SDN)

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!
