Flow specification
A flow specification is a description of the requirements for the quality of service in communication networks . In this way, a sender would like to indicate which qualities are required for the transmission of its data, for example in order to reserve appropriate resources (see Resource Reservation Protocol - RSVP).
The quality of service requirements can be divided into three categories:
- " Best Effort ": the transmission takes place "as best as possible"
- "Rate sensitive": a guaranteed transmission rate is required
- "Delay sensitive": a guaranteed transmission time is required
