Re: [ipwave] I-D Action: draft-ietf-ipwave-ipv6-over-80211ocb-01.txt - handover paragraph

[Alexandre Petrescu <[e-mail]>]

Dick,

Please refer to this document when commenting:
draft-ietf-ipwave-ipv6-over-80211ocb-01.txt

If I understand your Word correctly, you propose the addition of the
following paragraph at the end of the introduction section.

> [RR1]There are currently no specifications for handover between OCB
> links since these are currently specified as LLC-1 links (i.e.
> connectionless).  Any handovers must be performed above the Data
> Link Layer.  Also, while there is no encryption applied below the
> network layer using 802.11p, 16092 does provide security services
> for applications to use so that there can easily be data security
> over the air w/o invoking IPsec.

If yes, then I will add it after this existing paragraph in the
Introduction:
> However, there may be some deployment considerations helping
> optimize the performances of running IPv6 over 802.11-OCB (e.g. in
> the case of handovers between 802.11 OCB-enabled access routers, or
> the consideration of using the IP security layer).

And remember that the "handover" description was moved out of the document.

Yours,

Alex

>> Abstract: In order to transmit IPv6 packets on IEEE 802.11
>> networks run outside the context of a basic service set (OCB,
>> earlier "802.11p") there is a need to define a few parameters such
>> as the recommended Maximum Transmission Unit size, the header
>> format preceding the IPv6 header, the Type value within it, and
>> others. This document describes these parameters for IPv6 and IEEE
>> 802.11 OCB networks; it portrays the layering of IPv6 on 802.11
>> OCB similarly to other known 802.11 and Ethernet layers - by using
>> an Ethernet Adaptation Layer.
>>
>> In addition, the document attempts to list what is different in
>> 802.11 OCB (802.11p) compared to more 'traditional' 802.11a/b/g/n
>> layers, layers over which IPv6 protocols operates without issues.
>> Most notably, the operation outside the context of a BSS (OCB) has
>>  impact on IPv6 handover behaviour and on IPv6 security.
>>
>> An example of an IPv6 packet captured while transmitted over an
>> IEEE 802.11 OCB link (802.11p) is given.
