Use of the ProviderSpecific Buffer as a Receiver

Receivers can use the ProviderSpecific buffer to do the following:

While making QOS requests, receivers can:

• Specify nondefault RSVP reservation style, flow descriptors, and filter specifications.
• Request RESERVE CONFIRMATION.
• Specify one or more policy elements (policy information) to RSVP.

While receiving notification, such as getting additional information from the sender, receivers can:

• Retrieve policy information
• Retrieve QOS and RESV_CONFIRM events.
