Octoshape experience: a matter of quality Stephen Alstrup Octoshape August 2008 email@example.com
Octoshape Founded in 2003 by leading algorithm experts working with universities and industry as Akamai, Google, Microsoft, AT&T on large scale internet problems Offering high quality, low cost, massive scale streaming CDN solutions/services using P2P Customers and partners includes largest media companies, CDNs, software companies in US, Europe and Asia
P2P Streaming Low Cost - Saving bandwidth, keep traffic local, use cheapest resources Massive scale - Save bandwidth, keep traffic local, use several resources High Quality ?
Typical end user experience Buffering Server busy Low picture quality No help to solve problems Complex: CPU, Bandwidth, Codec, player, DRM Typical broadcaster experience User problems Costly Lack of statistic, QoS Lack of tools: Scheduling, restrictions, monitoring Complex: Same as users and lack of agnostic and multi platform solutions. Streaming with/without P2P
Technical explanations (or excuses) Congestion problems Packet loss Packet delay Jitter One way communication Machine down Do not scale User machines... User..... Why do we have quality/QoS problems Yes there are technical problems. 1) But that is true also for other broadcast business areas... and we do watch TV without the same kind of problems. 2) Streaming should be like TV just with all the benefits from internet.
Streaming-Philosophy have to change from IT-Philosophy to TV-Philosophy No more excuses No more Sorry machine went down Streaming should be like TV: Just with all the benifits from internet
Live Streaming: High Quality From a distribution point of view Transport it - Multi fail over Transport it reliable - Throughput + loss resilient Transport QoS and statistic - Accurate and automatic information/solutions P2P always come with Some fail over Software on the machine Not (just) a matter of high bit rate
The Web cast was excellent. I did not loose the 700 Kb per second at all during the whole 2.5 hour event. Webcast from the Octoshape player was a dream to watch with constant 698K stream Is this going to be the first EVER web cast that I could actually watch live and enjoy with out low res rubbish and picture break up and freezes?? surprisingly good quality Quality was fantastic. At 700kps … no skip frame. Eurovision song contest (ESC) is the largest non-sporting event in Europe – a little like American Idol, Octoshape have for three years been exclusive streaming provider for EBU holding ESC rights streaming to millions of viewers
Multi fail over just like TV Single point of failure Encoder 1 Encoder 2
Multi fail over just like TV Single point of failure Peer2 Host 2 Peer1 Host 1 Tradeoff between price, quality and scalebility
Multi fail over just like TV Single point of failure Wireless Wired Automatic switch among http, https, tcp, udp, … guarantees availability
Airplane streaming High packet loss and ping times = Normal (TCP) streaming do not work: Octoshape solution: Having packet loss of e.g. 5%, Octoshape simply sends a little more packets Wireless routers No edge server Satellite connections Bad hops
Keynote: Worlds Largest global test and measurement network First time: P2P delivering quality can be monitored by third party.
Multi fail over just like TV Single point of failure Monitoring Alert Automatic quality and QoS tools
Multi fail over just like TV Single point of failure Quality and QoS Octoshape claim: Quality and QoS requires software from encoder to end-user Facts: P2P always comes with software at end-user and some fail over.
Side effect of high quality and QoS Less support needed Support needed is more easy
