Reservation Components
RESV messages contain flow descriptors:
- a FlowSpec and FilterSpec
- FlowSpec contains QoS parameters
- FilterSpec, together with a session identifier consisting of an address/port/proto tuple, defines the “flow” to receive the QoS
FlowSpec generally contains
- service class (e.g. CL, guaranteed, etc)
- TSPEC, RSPEC parameters (formats are specific to the service class)
