3. December 4th, 200716ng WG, IETF703 Area Director Review Area Director, Jari reviewed draft-ietf-16ng-ps- goals-02 Comments –Technical comments: 4 –Editorial comments: 6

4. December 4th, 200716ng WG, IETF704 Technical Amendments Section 4.1 Root Problem –Ethernet like link model part –Comment What’s the real problem in realizing the Ethernet like link model in case of the Ethernet CS? –Amendment Addition of the following sentence. –“There needs mechanisms like IEEE 802.1D to realize multicast and broadcast for Ethernet CS.”

5. December 4th, 200716ng WG, IETF705 Technical Amendments (2) Section 4.2 IP CS: Problems –Address Resolution part “Blocking ARP or the address resolution of NDP needs to be implemented by SS itself in an implementation manner.” –Comment No mention of such blocking in the ipv6-over-ipv6cs. Would blocking NDP packets break IPv6 NUD? –Amendment Separate problem description for each IPv4 and IPv6 Addition of the following sentences for IPv6 case. –“For IPv6, address resolution is the function of IP layer and the IP reachability state is maintained through neighbor discovery packets. Therefore, blocking neighbor discovery packets would break the neighbor unreachability detection model.”

6. December 4th, 200716ng WG, IETF706 Technical Amendments (3) Section 4.2 IP CS: Problems (cont.) –Nits are caused by the previous assumption of the shared prefix link model for IP CS. Router Discovery –Texts about source address inclusion in the RS Neighbor Unreachability Detection –Texts regarding multiple ARs existence –Amendment All related parts are deleted.

7. December 4th, 200716ng WG, IETF707 Editorial Amendments Overall –Reference correction to RFC4903 –Expand “SDU” to “Service Data Unit” –Deletion of the “Section 2. Requirements” Clarification and correction –Section 1. Introduction …(CS) is at the uppermost part of the MAC… –Section 4.2 IP CS: Problems …Implementation manner specific fashion… –Section 4.3 Ethernet CS: Problems However, if not filtered (e.g., [RFC4541]), this these multicast and broadcast packets results result in the problem of waking up the sleep/ idle [IEEE802.16e] SSs.
