Ed Perry, HP Labsed.perry@hp.com MMNS 2002 Is the Internet ready for multimedia?(in production networks)
Where does Multimedia work today? Examples: • Hewlett-Packard • Seoul • CinemaNow.com • www.KFOG.com
What are the characteristicsof working Internet Multimedia? One or more of the following • Common administration • Special purpose “private” internets • Enterprises (even with multiple AS domains) • Some localities • Engineering for “adequate” or “over” capacity • Small bandwidth media • Audio • Small image • TCP transport • Download and play • Broadband to home, to users • Peer-to-Peer & “Sharing” • Digital Rights Management
Is the Internet ready for Multimedia? Yes... • Depending where you live/work, relative to the source • Depending on the nature of the content • bandwidth, digital rights, ... • If you are willing to use download and playback • Depending on your willingness to pay for service “This GOOD ENOUGH” can prevent the development of “BETTER”
What are the remaining hurdles? Problems with significant Business / Political challenges • Business models for service provider interoperation • Live, large-scale service consumption • Interplay of • High bandwidth media • Broadband to users • Digital Rights Management Problems with additional Technical Challenges • Exploding numbers of content providers and source locations Management!
Network Manager Concerns about Multimedia • Don’t break my existing network services • Don’t overload my network links and routers • predict the loading? enforce rate limits? • Minimize “risky” new software, equipment, configurations • multicast, RSVP, QoS, etc. • How do I control multimedia traffic (sources)? • What are the security risks? Denial-of-service risks? • How do I isolate / debug performance issues? • How do I assess service-level objectives? • in advance of use / need? • during use?
“Production” Network Manageability (1) • Multicast service assessment • Device manageability • Vendor support for IETF standard multicast MIBs (ipmroute, igmp, pim) • Extensions for fault isolation, IGMPv3 & PIM-SSM • Management tools that utilize the device manageability
Traffic Impact: barely 2% of capacity on selected router interfaces
“Production” Network Manageability (2) • Multicast service assessment • Device manageability • Vendor support for IETF standard multicast MIBs (ipmroute, igmp, pim) • Extensions for fault isolation, IGMPv3 & PIM-SSM • Management tools that utilize the device manageability • Multimedia service assessment • Synthetic • Real-user activity • Possibility of further technical innovation here!
HP Streaming Media Service Synthetic tests • 150kbps synthetic media stream, via multicast to 24 sites • Except one site: all < 0.7% loss, < 45mSec delay, < 56mSec jitter from NetIQ Chariot
Multimedia Operator Concerns about Networks • How do I make money? • How do get a guarantee of service from the network provider? • How do I estimate load? • How do I protect digital assets? • How do I avoid denial-of-service attacks? • How do I assess my service? • Synthetic • Real user activity • Same possibility of further technical innovation here! These needs are common to both Network and Multimedia Operators
Media Service Quality AssessmentCommon Need of both Network and Media Operators • As near to the human as possible, but without subjectivity issues • Correlated with MOS, etc. • Support for synthetic testing as well as real end-user assessment • Cope with large-scale, simultaneous audiences • Manage privacy and end-user security • Resilient to hacking and denial-of-service • Independent of transport, encoding, distribution network, etc. • Usable by the network operator, the media service operator, or even the content owner
