Resending this (it seems the first attempt fails... appologies if you
receive duplicate copies...).

Hi,
while going over the LWAPP draft and on the objecives of CAPWAP there
seems to be a CAPWAP objective that may not be fully achieved with
the current LWAPP spec.
The LWAPP specification requires that the 802.11 frames would be
encapsulated by the WTP and sent to the AC for processing. The benefit
from doing this is having the original info carried in the .11 frame
available to the AC.
However, this requires the AC to process the native 802.11 frames; an
operation that will probably be done in some HW component. My concern is
that one of the CAPWAP objectives was to be applicable not only to 802.11
but for various wireless technologies. As a result the LWAPP should also
be applicable no only for 802.11... (as it indeed states in the beginning
of the LWAPP draft). However mandating that the wireless media frames
would be sent to the AC in their original format would make this objective
harder to achieve... When a new wireless media type would be introduced,
the AC would have to be somehow adapted to process the data frames (not
only the control frames that can obviously be processed in the AC cpu...).
This means either a HW change (or if the AC is using NP then an NP SW
upgrade).
What seems reasonable to do is to add the OPTION for sending the
data frames to the AC using the media type tha tthe WTP is connected to
the AC with. Meaning - to convert the frame in the WTP and to send it to
the AC for instance using 802.3 ethernet frames... This way when a new
wireless technology is inroduced to the AC all that needs to be done is
updating the SW of the AC.

As for loosing the specific media information that was in the 802.11
header - this info can be collected by the WTP and be sent to the AC using
LWAPP protocol messages...

Supporting both the current LWAPP suggestion (sending the original 802.11
frames to the AC) AND the option to convert to the AC media type will
allow LWAPP to comply to the "future wireless technologies" objective...

Tal,

Thanks for the e-mail.

I believe that I understand your point, but I would argue that the AC
will have to be modified to support a new technology, and that upgrading
the code in the data path is really no more difficult than the control
path. If an implementation exists that does not allow for upgrade, then
it is limiting its market.

I would argue that include "technology specific" information piggy
backed within the LWAPP data frame would be hard to achieve, because we
cannot predict what this information would end up being. For instance,
802.11 has the concept of a BSSID, while 802.16 has something different
(and has additional information). So how would you map 802.11 QoS field
into a field that may not match with 802.16s?

If one were to need to extend the piggy backed header, then this would
require changes to the data path anyhow. Further, certain features will
require changes to the data path, for instance the introduction of
802.11i centralized encryption requires that the data path perform
AES-CCMP, and 802.11e requires specific quality of service queuing and
policing.

So while I understand the point raised, I firmly believe that
transporting the native frame provides the AC with all of the
information for the specific technology, and allows it to provide
differentiated services based on the information present - vs. limiting
it to what generic information would be in this piggy backed header.

Hi Pat.
Upgrading the data path is possible if you have, for example, a network processor performing the data path task. If your AC is based on regular ethernet switch built with ASICs for the data path packet processing (common practice), then you can easily upgrade the control plane but not the forwarding plane....(assuming that all the ACs will be based on HW that allows to easily upgrade to various L2 packet formats seems to me like assuming to have some NP-like capabilities in the AC....).
 
As for the piggybacking of the "technology specific" data... My intention was to extract this info and send some summary periodically to the AC using the LWAPP control messages and NOT to piggyback the data packets of the 802.3 with this info... Otherwise you would be correct of course that this would not give much benefit. However doing this in the control path and not the data path allows you to define new LWAPP protocol messages/fields for summarizing "technology specific" data as new technologies are introduced...
 
As for differentiated services - the QoS portfolio that the AC can provide, is usualy at least as good as what 802.11 can provide... for instance if you use ethernet 802.3 framing from the WTP to the AC you can mark whatever you need on the frame (not to mention if the traffic is IP traffic and you have additional DSCP field). Also if the packet is suppose to traverse another switch on the way to its destination then anyway it will get the QoS that the switch can assign it to the next link towards the destination... Thus I dont see a real benefit in keeping the wireless media original framing... 
 
IMHO extending the LWAPP protocol to support the OPTION for using the AC specific link layer format (in most cases it would be 802.3) would be beneficial in the future and would give LWAPP the flexability that it needs in order to comply to the "applicablity to future wireless technologies"...

Well, obviously the WG needs to decide, but frankly I see this as being
no different than say IPv6 or even 802.1q (for those IEEE heads).
Changes in protocols require hardware/firmware changes. I believe that
sending "periodic" information about data frames is not useful and that
in order for the AC to act as an AP, it needs the data on each and every
frame. Such things as signal strength, for instance, allows the AC to
make predictive mobility decisions and cannot be represented in 802.3
frames.

Pat,
As I indicated below, there are cases where local AP is implemented and in addition there is small deployment scenarios, will not really burden the CPU. Also, a packet doesn’t need to be sent per each data packet but rather only when a threshold is met

But regardless, 802.3 frames seems to me to be the more generic case, while 802.11 is a specific media, not related to the AC technology which is usually Ethernet. And as indicated on a different mail thread, seems that with the 802.11 frame format, LWAPP is not fully compliant with the CAPWAP objectives (supporting all wireless formats) 

(And one correction to a typo I made below: LDAP should read LWAPP)

Yuval,

I'd like to comment on your point about having the WTP process the
information, and provide a digested version of the information. How
would you propose that the WTP represent the changes in signal strength
(which occur in real time) to the AC - and how frequent would you
propose these updates be made? Would this be a packet that hits the
control processor, because if so, then I have some serious scaling
concerns.

That said, I think that in the end we need the evaluation team to make a
recommendation on a protocol, and then let the WG decide. If the WG
decides that two separate protocol formats would be better than one,
then we can go down that path (and make sure that we make one mandatory
to implement).

In the CTP draft, which is likely more aligned with what I would call a
Local MAC implementation rather than an split MAC implementation, we tunnel
802.3 frames. In the case of local MAC, you are bridging data to 802.3 at
the WTP so it makes sense to tunnel 802.3 frames.

Practically speaking, the only additional information in an 802.11 frame
(MSDU) is a BSSID. In most  implementations, the BSSID maps to a VLAN tag in
802.3. However we found for fast data plane processing we mapped the BSSID
to a Network ID in the CTP header. We have also provided the option for the
WTP to send the RSSI and RATE as part of the CTP header.

In the split MAC case, I could see the value in the WTP passing the 802.xx
frame to the AC in a tunnel. I still think you would want to for adding the
network ID (representation of the SSID/BSSID) as part of the CAPWAP protocol
header to aid in data plane processing.

On the QoS side, I think you definitely need to apply the equivalent
priority from the data frame to the tunnel header.

I would say from a requirements perspective, the tunnelled data packet must
include:
1) A data frame indicator in the header.
2) A Network ID in the header.
3) The SRC MAC, DEST MAC, and PAYLOAD
4) QoS information in the tunnel header. 

The open issue is what additional information could be given:
1) PHY specific information. For example, RSSI and RATE in 802.11.
2) MAC-specific information.

I think in the split-MAC case, you could make an argument for using either
type of data frame in the tunnel header. A 802.xx MAC header may involve
slightly less processing than an 802.3 header at the WTP. But I really don't
think there's much of a difference.

In a local-MAC case if you tunnel data to the AC, then it would make more
sense to use an 802.3 format for the data.

Cheers,

	Mike

Bob,
the discussion is not only about local MAC but also about split MAC. The local MAC was given just as an example.
For reasons provided before, I see also a lot of sense in using 802.3 frames also in the split MAC case, where you do the distribution function (based on 802.3 frame switching) within the AC
Since in any case you need to add the 802.11 specific info (like RSSI), I'd rather see it within the LWAPP tunnel header so I can choose if to take it from there or not and keep the frame 802.3. This will give the most flexibility for those implementations that need the extra info and for those looking into simple implementations not requiring processing the extra info or allowing processing in the WTP 

I would like to hear more opinions on the WG mailing list as to how important it is to support this also in split MAC case

I guess I fail to see what this controversy is all about.  If you want
to forward 802.3 frames from the WTP, you are using the local MAC
variant supported by LWAPP.  In fact, that is what the taxonomy draft
specifies.  

If all you have in your AC is Ethernet switch silicon on the data path,
this is the only reasonable implementation.  To say that another option
is necessary to support conversion of 802.11 frames to 802.3 frames in
the WTP in split MAC mode, separate the 802.11-specific information and
forward the 802.3 frames and separated 802.11 information about those
forwarded 802.3 frames in LWAPP packets is ridiculous.  Just because you
have a hammer, doesn't mean that everything else in the world is a nail.

It seems that this is a tremendous complication to the AC, which now
needs to correlate this separated information.  This correlation
operation was not necessary when the 802.11 frames were forwarded
directly, since the frames and their information arrived whole and
together. 

In order to reduce the computing load on the AC to correlate the
separated information, the WTP could send only summarized information.
Of course, this reduces the amount of information available to the AC,
without justification.

Pat,

Your question is independent of whether CAPWAP tunnels 802.3 or 
802.11 frame. Signal strength field does not present in 802.11 frame 
headers. Having tunnel 802.11 frames doesn't solve the problem.

All,

IMHO supporting the case where 802.11 <-> 802.3 conversion is done at the WTP and 802.3 is transported to AC is important to leverage existing silicon in the data path at the AC. This can be accomplished in many ways in CAPWAP - one option that seems to be under debate is to consider this as a mode of Split MAC. 

Another, something I like better and not very complicated, is to consider this an Local MAC option where the integration/portal function of 802.11 AP is at the AC. With this model, LWAPP control protocol (in the Local MAC case) could negotiate the encapsulation for the data path to the portal. This could be GRE, LWAPP(L2/L3) or whatever - with inner payload of 802.3. RSSI/SNR/etc values can be obtained from the encapsulation header...

Split MAC could carry 802.11 only in the data path.

    Bob,
    the discussion is not only about local MAC but also about split MAC. The
    local MAC was given just as an example.
    For reasons provided before, I see also a lot of sense in using 802.3
    frames also in the split MAC case, where you do the distribution
    function (based on 802.3 frame switching) within the AC
    Since in any case you need to add the 802.11 specific info (like RSSI),
    I'd rather see it within the LWAPP tunnel header so I can choose if to
    take it from there or not and keep the frame 802.3. This will give the
    most flexibility for those implementations that need the extra info and
    for those looking into simple implementations not requiring processing
    the extra info or allowing processing in the WTP
    
    I would like to hear more opinions on the WG mailing list as to how
    important it is to support this also in split MAC case

    I guess I fail to see what this controversy is all about.  If you want
    to forward 802.3 frames from the WTP, you are using the local MAC
    variant supported by LWAPP.  In fact, that is what the taxonomy draft
    specifies.
    
    If all you have in your AC is Ethernet switch silicon on the data path,
    this is the only reasonable implementation.  To say that another option
    is necessary to support conversion of 802.11 frames to 802.3 frames in
    the WTP in split MAC mode, separate the 802.11-specific information and
    forward the 802.3 frames and separated 802.11 information about those
    forwarded 802.3 frames in LWAPP packets is ridiculous.  Just because you
    have a hammer, doesn't mean that everything else in the world is a nail.
    
    It seems that this is a tremendous complication to the AC, which now
    needs to correlate this separated information.  This correlation
    operation was not necessary when the 802.11 frames were forwarded
    directly, since the frames and their information arrived whole and
    together.
    
    In order to reduce the computing load on the AC to correlate the
    separated information, the WTP could send only summarized information.
    Of course, this reduces the amount of information available to the AC,
    without justification.

    Pat,
    
    Your question is independent of whether CAPWAP tunnels 802.3 or
    802.11 frame. Signal strength field does not present in 802.11 frame
    headers. Having tunnel 802.11 frames doesn't solve the problem.

How do you define an RF threshold, and given the wide variations that
can exist between packets in most environments, how do you guarantee
that this doesn't negatively impact the WTP/AC performance?

[YC] this is definitely not the scope of CAPWAP to define the exact thresholds.

Respectfully disagree. We haven't decided how 802.16 is mapped onto the
CAPWAP protocol. Therefore the LWAPP protocol allows it by being
flexible in allow the native frames to be tunneled. So it does in fact
comply with the standard.

[YC] with the cost of having different frame format for each wireless media...

So this would be an argument for local bridging and tunneling of 802.3 frames in local mode. I think that would be a good compromise. I believe that changing the basic fundamentals of Split MAC, which means *all* AP functions are performed in the AC (possibly including encryption), would be a mistake.

The taxonomy recommendation already recommends that Local MAC be the "mandatory" mode, but if the WG agrees, we could make changes to allow for tunneling of traffic in an 802.3 mode.

In reviewing the taxonomy document (v6) in the light of this discussion, it seems that this option does not allow, for example, 802.11 mgmt frames to terminate at AC with 802.3 in the data plane. As I understand only Split MAC allows 802.11 mgmt frames to terminate on the AC. Such a combination would be useful because 802.11 frame can easily be processed in software in the control path.

Another way to think about this issue, without changing the semantics of Split/Local MAC terminology, is to treat control and data planes separately, in line with the CAPWAP separation of control/data objective, and allow Split MAC or Local MAC to be negotiated independently for control & data via the CAPWAP protocol. Current usage of Split MAC and Local MAC each of which have requirements on the data and control planes is causing some confusion ( at least for me).

I would agree with this using 802.3 for local MAC and 802.xx for split MAC

I think the only assumption is - if local MAC then integration service may be performed on WTP.

Also according to my read of Fig 9 - arch taxonomoy draft (v6) 802.1x authenticator may be on WTP for local MAC

      So are we saying that if the integration service is performed on the
    WTP
    then you're "local MAC" regardless of any of the other non-real time
    functions that may be done on the AC? I'm not sure I agree with that.
    
      By the way, if the 802.1x authenticator is on the AC then I think you
    are by definition a split MAC. No?

As terminating 802.11 at the WTP, converting to 802.3 and sending to the AC may be a good idea, I would argue against specifying this embodiment as mandatory. It border impossible to ensure that WTP to AC communication will always travel over 802.3 network. Although I concur it's the common practice in LAN environment, I would challenge its applicability to the WiMAX, or for that matter to other wireless technologies.

Bob,
the discussion is not only about local MAC but also about split MAC. The local MAC was given just as an example.
For reasons provided before, I see also a lot of sense in using 802.3 frames also in the split MAC case, where you do the distribution function (based on 802.3 frame switching) within the AC Since in any case you need to add the 802.11 specific info (like RSSI), I'd rather see it within the LWAPP tunnel header so I can choose if to take it from there or not and keep the frame 802.3. This will give the most flexibility for those implementations that need the extra info and for those looking into simple implementations not requiring processing the extra info or allowing processing in the WTP 

I would like to hear more opinions on the WG mailing list as to how important it is to support this also in split MAC case

I guess I fail to see what this controversy is all about.  If you want to forward 802.3 frames from the WTP, you are using the local MAC variant supported by LWAPP.  In fact, that is what the taxonomy draft specifies.  

If all you have in your AC is Ethernet switch silicon on the data path, this is the only reasonable implementation.  To say that another option is necessary to support conversion of 802.11 frames to 802.3 frames in the WTP in split MAC mode, separate the 802.11-specific information and forward the 802.3 frames and separated 802.11 information about those forwarded 802.3 frames in LWAPP packets is ridiculous.  Just because you have a hammer, doesn't mean that everything else in the world is a nail.

It seems that this is a tremendous complication to the AC, which now needs to correlate this separated information.  This correlation operation was not necessary when the 802.11 frames were forwarded directly, since the frames and their information arrived whole and together. 

In order to reduce the computing load on the AC to correlate the separated information, the WTP could send only summarized information.
Of course, this reduces the amount of information available to the AC, without justification.

I respectfully disagree with the assumption that Split MAC is define as *all* AP functions in the AC, and in particular the DS. This issue was exhausted in the list. If my memory server me right the key arguments in favor of offload the DS to the WTP were:
- CAPWAP is a control protocol, has nothing to do with data flow
- Avoid hammering the AC with data traffic
- Shortest path for data packets

Emek

The claim was not to demand translation to 802.3 but rather to the applicable media. If the media is 802.3 LAN than translate to 802.3 if it is frame relay, translate to it etc

I will point you to figure 12 in the taxonomy document. In ALL six cases the Split MAC architectures handle both the DS and the IS functions in the AC. So I wonder why we should consider creating a protocol for which no products would use? 

Let's keep this simple and focus on market need.

Pat,

Thanks pointing it out. However, I think that the fact that, at time, all Split arch. vendors incorporated the DS at the AC shouldn't discourage the group from structuring a protocol that can comprehensively support various applications.

The IETF mandate working group to satisfy market requirements not to create a protocol to support existent products, that at time may not have been mature enough.

Emek
