[RE] Fw: [RE] Stream identification at the MAC SAP

Title: Objectives summary for a paper ...
When typing I have changed 2 by 3:  As you know, LLC Type 2 is 802.2, not (802.3).

Have you revised the documents of the IEEE 802.9 ISOCHRONOUS LANs?

 

This Working Group, now disbanded, developed standards for Isochronous LANs, called “Iso-Ethernet”, which combines the properties of IEE 802 LAN and ISDN networks (Plesiochronous Digital Hierarchy). I believe that they can have interesting information, since they developed an isochronous system of local network.

 

With respect to the second question, the protocol able to identify data streams is the LLC type 2 (802.3),  by means of  the P/F bit.

Subject: [RE] Stream identification at the MAC SAP

I have a general question on the MAC-SAP interface for RE.  All 802 standards are required to support the 802.2 interface.  The 802.2 interface does not provide a way of identifying an isochronous stream to the MAC at the MAC SAP.  When 802.2 was up for reconfirmation last year I suggested that they add a stream identification parameter that could be used for protocols that provide isochronous services like 802.15.3 or now 802.3 RE.  802.2 rejected the comment. 
 
Has anyone given a thought to how streams would be identified at the MAC-SAP?  Would there be optional parameters added beyond those provided by the 802.2 interface?  The current parameters from 802.3 are listed here:
 

MA-UNITDATA request (

source_address,

destination_address,

routing_information,

data,

priority,

service_class

)

and from 802.3:

MA_DATA.request (

destination_address,

source_address,

m_sdu,

service_class

)

Thanks.
