Re: [STDS-802-Privacy] FW: [802SEC] Proposed PAR: P802c - Overview and Architecture - Amendment: Local Media Access Control (MAC) Addressing




Reading these 802.1 documents, they are ill-conceived (IMHO).

     From "new-addresses-thaler-local-address-csd-v01.pdf “:
A first step in enabling protocols for claiming or assignment of Local MAC
addresses is to organize the MAC address space so that entities
can be assigned a block of the Local Address space
through the Company ID (CID) as a default.
Another part of the space will be defined for local administration.

The ‘first step’ is not required and is detrimental.  There is no reason to organize
a locally defined address space.  The larger the space the less collisions 
(46 better than 24 bits).  The ‘organization’ of providing CID prefixes 
has no identified value.  A "Company Id” also leaks information and
is a problem for privacy usage of local addresses.

Local addresses should simply be uniformly distributed over the available 46 bits.

All,

 

As mentioned by Max, this proposed 802c PAR is relevant to the discussions we are currently having about the use of the local MAC domain. The intention of the proposed project is to describe the rules for assigning local MAC addresses:

 

From PAR:

“5.2.b. Scope of the project:

The amendment will provide recommendations and rules for using the local address space. This will allocate a portion of the address space for protocols using an IEEE Registration Authority assigned Company ID. Another portion of the local address space will be allocated for assignment by local administrators.”

 

From CSD:

“A first step in enabling protocols for claiming or assignment of Local MAC addresses is to organize the MAC address space so that entities can be assigned a block of the Local Address space through the Company ID (CID) as a default. Another part of the space will be defined for local administration.”

 

It is assumed that the Privacy group should be able to leverage from this project/specification, so we should consider providing inputs.

 

Juan Carlos

FYI, for the case you are neither subscribed to the [802SEC] list nor to the [802.1] list.

The project may provide the basic rules and protocols for dynamically assigning MAC addresses.

And the project may appreciate input on the privacy use case. Privacy is currently not mentioned in the PAR.

 

Bye

Folks,
 
The July 802.1 plenary authorized the 802.1 interim to draft a PAR & CSD for on the local address space.  The proposed PAR for P802c is posted here:
 
http://www.ieee802.org/1/files/public/docs2014/new-addresses-thaler-local-address-par-v01.pdf 
 
The  new 'CSD' is here:
 
http://www.ieee802.org/1/files/public/docs2014/new-addresses-thaler-local-address-csd-v01.pdf 
 
These are for pre-circulation to meet the 30-day requirement for November plenary EC approval to forward to NesCom.
 
Cheers,
Glenn.
