Please see in-line. [SC>] I am forwardig these comments originally from Sangeun Kim at KT to 16ng list. [SC>] Thanks. ======================================== 6. Subnet Model and IPv4 Address Assignment The Subnet Model recommended for IPv4 over IEEE 802.16 using IP CS is based on point-to-point link between MS and AR, hence each MS will be on different IP subnet. Proposed Changes: The Subnet Model recommended for IPv4 over IEEE 802.16 using IP CS is based on point-to-point link between MS and AR. [SC>] Fine by me. 7. Address Resolution Protocol The IEEE 802.16 frame header does not contain the source and destination MAC addresses, instead it uses the Connection Identifier (CID) for the delivery of MAC frames. This makes classical Address Resolution Protocol (ARP) [3] trivial and unnecessary. > Also, IEEE 802.16 IPCS cannot classify the ARP packets as ARP runs directly over Ethernet and does not contain IP header. Thus ARP packets are not transmitted over IEEE 802.16 air interface when using IPCS.

Thus ARP packets are not transmitted over IEEE 802.16 air interface when using IPCS. However MS requires to proxy ARP function compatible with legacy IP host. [SC>] Let's discuss the last sentence. MS requires to proxy ARP function compatible with legacy IP host: What is the expected configuration of the scenario in this case? The legacy IP host will not be on the same Wimax IPCS link; thus our assumption was that they would be on different subnets. Please clarify.
