Soft Real-Time

• Real-time computations have deadlines

  • Soft Real-Time: no catastrophe if deadline is missed

• Examples

  • Soft modem:
    • Missed deadline may reset connection
  • Video conferencing:
    • Missed deadline degrades audio or video
  • Burning a CDROM:
    • Missed deadline may generate a coaster

• Soft real-time deadlines not always very soft

  • Users hate sound glitches, jerky games, etc.
