Issue

We think that BRCB structure misses the attribute Resv, defined for URCB according to paragraph 14.2.4.5, to protect the Report Control Block configuration process by a client.

Proposal

Include in the BRCB structure the attribute Resv to protect the Report Control Block configuration process by a client.

A OPTIONAL attribute ResvTms - Reservation time - has been added to the BRCB:
"The values of the attribute ResvTms are defined as follows:
• A value of -1 shall indicate that the BRCB is currently exclusivly reserved for a set of specific clients based upon configuration.
• A value of zero(0), shall indicated that the BRCB is not reserved.
• A positive value shall indicate that the BRCB has been dynamically reserved. The value represents the number of seconds that the reservation will be maintained after association loss. Upon expiration of the reservation, the ResvTms value shall be locally set to a value of zero(0)
A SetBRCBValues request, for setting ResvTms, shall:
• Generate a negative response if the BRCB’s ResvTms value is non-zero and if the SetBRCBValues request is being issued by another client for whom the BRCB is not reserved.
• Generate a negative response if the BRCB’s ResvTms value is -1.
• Generate a negative response if the ResvTms value to be set is negative.
• Generate a positive response if the BRCB’s ResvTms value is zero(0) and the value being set is zero(0) or positive.
• Generate a positive response if the SetBRCBvalues request where:

the ResvTms value, being set, is zero(0) or positive,

and is from the client for which the BRCB has been reserved via a positive value." 		13 Dec 06 Ballot Period
