Is the Internet ready for multimedia?(in
production networks)

• Ed Perry, HP Labsed.perry_at_hp.com
• MMNS 2002

2
Where does Multimedia work today?

• Examples
• Hewlett-Packard
• Seoul
• CinemaNow.com
• www.KFOG.com

3
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
5
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

• Dont break my existing network services
• Dont 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

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 lt 0.7 loss, lt 45mSec delay,
  lt 56mSec jitter

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
