The IP unicast or multicast destination address of the session. This field must be non-zero.
The IP Protocol Identifier for the data flow. This field must be non-zero.
The E_Police flag is used in Path messages to determine the effective "edge" of the network, to control traffic policing. If the sender host is not itself capable of traffic policing, it will set this bit on in Path messages it sends. The first node whose RSVP is capable of traffic policing will do so (if appropriate to the service) and turn the flag off.
The UDP/TCP destination port for the session. Zero may be used to indicate `none'.
Other SESSION C-Types could be defined in the future to support other demultiplexing conventions in the transport- layer or application layer.
