1- Resource translation
- Application asks for end-to-end quality in terms of bandwidth and delay
- How to translate to resource requirements in the network?
- Bandwidth is relatively easy, delay is hard
- One approach is to translate from delay to an equivalent bandwidth
- can be inefficient if need to use worst case delay bound
- average-case delay usually requires strong source characterization
- Other approach is to directly obtain per-hop delay bound (for example, with EDD scheduling)
- How to translate from end-to-end to per-hop requirements?
