stds-80220-requirements: Section 4.1.15 QOS
Folks,
There appears to be a slight confusion in the current requirements
document between sections 4.1.15 QOS and 4.4.1 Quality of Service
and the MAC.
I'll clarify 4.1.15 first. I'll clarify section 4.4.1 in a follow up
email to this one.
Section 4.1.15:
Current text:
The AI shall support the means to enable end-to-end QoS within the scope of
the AI and shall support a Policy-based QoS architecture. The resolution
of QoS in the AI shall be consistent with the end-to-end QoS at the Core
Network level. The AI shall support IPv4 and IPv6 enabled QoS resolutions,
for example using Subnet Bandwidth Manager. The AI shall support efficient
radio resource management (allocation, maintenance, and release) to satisfy
user QoS and policy requirements.
Action:
Delete phrase "for example using Subnet bandwidth manager"
Rationale: Subnet bandwidth manager (SBM), defined by RFC 2814, addresses
the issue of IntServ RSVP bandwidth reservation over local area networks.
Bandwidth reservation is not a meaningful concept with non-deterministic
physical layers such as one would expect to see in a mobile radio system.
Section 4.4.1 of this document, moreover, calls for a DiffServ QoS model.
