Q how much bandwidth
Q. How much bandwidth?

  • A. It’s variable.

    • Things that affect bandwidth

      • Number of contacts

      • Presence changes every hour

      • Quantity of IM’s

      • Quantify of messages per IM session

    • At Microsoft IM and Presence take up approximately 1.8 kbps per user over the course of a working day.

    • Stress test tool in the Resource Kit

Q how much bandwidth1
Q. How much bandwidth?

  • Video:

    • Variable, but plan for 300k max per stream

    • SMPTE VC-1 compliant codec called RT Video

    • RT Video is enhanced to scale down bandwidth based on network performance

  • Audio:

    • Varible, but plan for 45k-50k max per stream

    • RT Audio codec

    • RT Audio is enhanced to scale down bandwidth based on network performance

  • Web:

    • 3-6kbs generally doing PPT push

    • 12-50kbs generally using application sharing

Note: we are not integrating with ‘legacy’ audio/video conferencing systems using H323, ISDN, etc. natively.

This will be done via gateways from 3rd party vendors.
