Conclusions

  • High-Level model for composite services adaptation
  • CASAS provides means to Pro-actively adapt composite

services (maintain SLA)

  • Need to do quantitative evaluation

Ongoing Work

  • Coordination layer
  • Hypothesis – intention propagation provides better

alternatives to service adaptation, than optimization solutions using static context information

“it might be worth-while to point out that the purpose

  • f abstracting is not to be vague, but to create a new

semantic level in which one can be absolutely precise”
