Re: [STDS-802-16] regarding service flow in 802.16
Hi,
1. I don't understand the concept of classifier priority (they say it takes value from 0 to 255).
>
Three CIDs: 0x80 01, 0x80 02, 0x80 03
0x80 01- Classifier=(src addr + dst addr)=192.168.0.1+192.168.0.100 +priority(1)
0x80 02-Classifier=(src addr + dst addr)=192.168.0.1+192.168.0.100 +priority(100)
0x80 03-Classifier=(src addr + dst addr)=192.168.0.1+192.168.0.100 +priority(200)
If a packet of 192.168.0.1+192.168.0.100 arrives at MAC_packet_CS, it will send the
packet with the CID 0x80 03.
The value of classifier is 255, but it may be any other value.
2. In 802.16 specification, address based rules define how data packet of different users are mapped to different service flows (your previous reply also states the same). This shows the Convergence sub layer should maintain the mapping information between upper protocols defined address.
a. So this will force the 802.16 CS to implement some upper layer functions???

Yes. Just like a soldier should know the command type or the command source.
b. Whenever there is a change in upper layer protocol, the change should be updated in MAC CS, this makes MAC CS non-generic???

In 802.16e, the classifier of packet is quite definite. In fact, MAC_packet_CS
is generic or non-generic in a way. However, the current specification can meet
our requirements.
