Bonjour donc voila dans le cadre d'un projet de doit notament creer cette primitive seulement je ne sais pas par ou commencer si vous avez une idee merci d'avance desoler mon sujet et en anglais.


Function
Inform CHF of a change in the parameters of a pipe. Furthermore it triggers CHF to reallocate flows to
other pipes if new pipe parameters are lower than sum of that required by the allocated flows.
Semantics of the service primitive
RtF_CHF_Pipe_Change.indication(
PipeID,
NewTrafficSpec
)

1)Parameter : PipeID Type : PIPE_ID
Description : identifier of the pipe

2)Parameter : TrafficSpec Type : TRAFFIC_SPEC
Description : - Traffic Class
-Bandwidth (kbps)
- Delay (ms)
- Loss (10E-4 resolution)
- Jitter (ms)


When generated
Primitive is issued by RtF to CHF if the parameters of a pipe has changed, e.g. as a consequence of a
link going down or a changed link data rate.
Effect on receipt
CHF checks if the sum of the allocated flows’ parameters exceeds the values; if yes, it will try to
redistribute some flows to other pipes (either to existing or to newly requested ones), after this excess
flows will be terminated..
