Re: [802.3_DIALOG] New 'Higher Speed Ethernet Consensus' Industry Connections activity



Thank you for providing the clarification.


IMHO, it is important for those not well-versed in the IEEE-SA hierarchy and rules to understand the following is a snippet of the charter of the IEEE-SA Industry Connections Program:

The IEEE-SA Industry Connections (IC) program helps incubate new standards and related services by helping like-minded organizations come together in a quick and cost-effective manner to hone and refine their thinking on rapidly changing technologies, and determine appropriate next steps. This program offers an efficient, economical, safe harbor environment for building consensus and producing shared results.

Because the IC program can help “incubate new standards” through providing an “environment for building consensus,” it is important to understand how this works relative to IEEE 802.3; especially considering 802.3 has different requirements than some of the other 802 working groups in the creation of new standards projects.


I fully understand the desire “to not factor in any assumed outcomes” in making the proposal for this IC effort. I do take away from your statement (and please correct me if I have misinterpreted) that your hope is the IC develops consensus on rate and that consensus carries over into the incubation of a new standard. Respectfully, I believe that this is an outcome that many whom are endorsing this effort are hoping to see.


If that is the “hopeful” outcome, then I would support this industry connections effort.

Let me respond to some of the issues that have been raised in this thread.


First of all, while some may feel things are more definitive of what can and can’t be done, what will or won’t be done, my take on proposing this IC has been to not factor in any assumed outcomes.  I have read these response interpreting people’s words as their opinions, and frankly, IMO, it illustrates the need for this open industry discussion. 


Next, the IC has been proposed in such a manner that it is not intended to be disruptive to the defined actual project process.  It is not proposing changing any rules where an IC would have to be done or completed prior to an actual CFI. 


All efforts I have been involved with in the past have never been closed or private.  The IC is merely another available tool for building consensus towards a CFI by providing a forum for industry discussion where awareness and participation of all potential stakeholders can be facilitated through the IEEE, which I believe all would agree, would help enable even broader reach and hence greater participation.  The only proposed deliverables is the historical records, i.e. meeting notes & presentations.  There is no decision outcome, though I think the forum would allow us the opportunity to do non-binding straw polls to get an assessment of the interest level.  I believe it is fair to say that a perceived outcome is that this IC will be helpful to a potential future CFI.


The rate question is perhaps one of the most explosive issues related to this whole effort, and it suggests that we review our rules.  Per the IEEE 802.3 Operating Rules, Section 4.2 Formation –


“A SG is formed when enough interest has been identified for a particular area of study within the scope of the WG. The first step in the process is a call for interest.”


So, in regards to the rate question, while Steve used the phrasing “make the rate decision during the CFI”, another way one might phrase the intent of his statement is that the IC would enable the group to evaluate the consensus of chooing 400G as the proposed area of study.  (Given my prior experience chairing the 2006-2007 HSSG, I hope some will understand why I can see the value if a choice were made).  Traditionally, however, my recollection is that no motion for a new speed project has ever stated the rate choice in the chartering motion.  Nonetheless, I personally wouldn’t see such a motion to be prohibited by the rules, but one cannot look at this issue with tunnel vision.  The consensus of the group, IMO, will have an impact on what motion might be decided to be proposed, how that motion might be treated on the floor during the WG session, i.e. amendments, and ultimately whether the motion passes.  I can share from my prior experience that there were many individuals who felt I should have included 100G in the chartering motion for the last HSSG.  Based on on-going conversations related to those I spoke with however, my own personal determination was that the inclusion of 100G would have been disruptive from my ultimate goal at that time, however, which was getting the Study Group formed.  And while some have very strong opinions regarding the current rate debate, which they have expressed, I can personally say, that in organizing this IC, I have heard strong opinions supporting differing points of views on the rate topicsubject. (Another example I would argue for this IC!)  And thus, I have proposed the IC in such a way that no decisions are implied, the IC merely provides a forum for the discussion and consensus building. 


I hope this provides the clarification that some individuals are looking for.

That’s for the explanation. It’s definitely a good level set for those that haven’t been through previous HSSG incarnations or who have not participated in call-for-interest (CFI) developments.


One aspect you mentioned (and I assume was a typo) is the statement, “make the rate decision during the CFI.” As you and I (and many others) know, the only decision that occurs with a CFI is whether or not to form a study group. The CFI is made Monday afternoon at the 802.3 opening session and voted upon at the closing session Thursday afternoon.


What is not mentioned in the email is whether or not the outcome of the industry connections (IC) is going to be a CFI. For example, if the intended outcome of the IC was stated as, “we will do a CFI for speed X” then that has a different impact than, “we may do a CFI for the next speed.” If the IC focus is to select the speed for the CFI and drive a CFI development, then that makes sense for companies interested to invest time and resources. If the IC effort is not going to select a speed or lead to a CFI, then other than networking with colleagues at a set place and time, this would result in companies investing time and resources with nothing to show for it.


Respectfully, it was not 100% clear. All I’m asking for is clarification.

Hi Brad and all,

I would like to speak in favor of this IC effort – like many of the others, I find that a lot of folks that I speak to, both inside of my company and at industry events, standards meetings and conferences are quite eager to see something get started on the “next rate”, and the level of interest is something that I think justifies an activity to meet the need.


You have observed, quite correctly, that we haven’t done it this way in the past several HSSGs in 802.3 history, so it is worth discussing what makes this different. I think there are two things that justify a different approach:


The first is that “pre-CFI” activities have generally been private efforts among a (small) group of like-minded participants who do the work to justify the project. If they meet during 802.3 meetings, they do so informally, as a “flash mob”, using one of the meeting rooms but not advertising it on the schedule. Given the large number of participants and companies who are interested in this, however, it makes more sense to do it as an open process, where anyone interested can join – to put the room on the announced schedule of sessions at 802.3 meetings, and to have an open email list that participants can join.


The second reason, which became quite apparent during 802.3ba, is that Ethernet is part of an ecosystem and does not stand by itself. Particularly at these very high rates, we are beyond the point where anyone will use such an interface anytime soon to connect to an end station, so these interfaces are generally carrying very large aggregates. For the part of the network where the next rate will play, you need to be able to carry that new rate of Ethernet over OTN. It could be that the IC effort puts together enough information to know that we need a faster rate without knowing what that next rate should be, but it is also be the case that what the IC learns will give good information for what the next rate should be. If this occurs, it would benefit the industry to make that decision early (e.g., to make the rate decision during the CFI), since that would enable IEEE and ITU-T work to proceed independently for each organization to work on developing aligned standards in parallel.

I guess I’ll be the first of those not participating in the BWA tutorial to speak relative to this new IC effort.


The question is being raised in the industry about what is the next speed of Ethernet and when will that occur. Personally, I have been asked that question ever since we started the previous Higher Speed Study Group (HSSG) that resulted in IEEE Std. 802.3ba-2010. The Bandwidth Assessment Ad Hoc helped explore and shed light on the drivers and growth potential that exists. This was a great industry connections effort that the IEEE 802.3 Working Group gets to put its stamp on.


What is harder to understand is how an industry connections effort leads into the potential development of a call-for-interest (CFI). During my 15 years in 802.3, speed increments CFIs have always been referred to as HSSG as the study group would pick the next higher speed. Is the industry connections effort looking to build consensus on what the next speed should be for the CFI and eliminate that selection process from the study group phase of the project? Or, will the next speed consensus built within the industry connection effort be irrelevant as the HSSG will still be in charge of selection the next speed?


I’m in favor of developing the next HSSG when the time is right. I also believe that the 802.3 Working Group should understand the process of how an industry connections activity feeds into a CFI. This is new territory for 802.3 and it would seem prudent to make sure there are no false expectations or misperceptions.

    Thread-topic: [802.3_DIALOG] New 'Higher Speed Ethernet Consensus' Industry Connections activity


I agree with Pete. We have been seeing growing interest from numerous network operators covering SP, MSO and Data Center spaces, to have clarity on when a next higher speed of Ethernet would be available.  Concern is that it will be available in time for their projected network needs. 


The sustained network bandwidth growth, driven largely by the increase in users and the increase in user consumption (such as  video) is challenging network's ability to scale.  Built into this need for a speed step is also the challenge of ensuring a cost effective solution. 


At the last interim meeting a number of interested people got together for an ad-hoc discussion around this topic.  At the close we took a straw poll to gauge interest in starting things moving towards a next HSSG project. Results indicated that there was strong interest in kicking this off.


In light of this, I support the
