MQC Traffic Shaping from 10G to 5G

Hi
I have a 6880x switch connected to a 5G link using 10G ports as follows
6880x---10gPort----------------5G link------------------10G Port---Nexus Switch
I want to shape the traffic leaving from the 6880x so that anything over 5G is buffered, this is a inter DC link.
I have put the following config together, Ive decided to tackle this using class maps. I am not sure if im on the right lines as its my first attempt. Not sure what goes in the ?????? area, im not near the switch to test but just trying to put some config together beforehand. Any help will be much appreciated.
class map Class_Shape_Traffic
match any
Policy-map Policy_Shape_Traffic
class Class_Shape_Traffic
Shape ??????????

I'm unfamiliar with shaping on either the 6880 or Nexus, but something like:
policy-map Sample
class class-default
shape average 4250000000
Might be what you can use.
I've shaped 15% slower than your 5 Gbps, because I believe many shapers don't account for L2 overhead.

MPLS Traffic Shaping/Policing on PE-CE link

Hi everyone,
We are considering to upgrade our remote sites to MPLS/VPN type of connectivity from ATM/FRASI.
Lets say we take a 10Mb link in the main office and 2-4Mb links for remote sites. Majority of servers (services) reside in main site, so majority of traffic flow will be from main site to remote sites.
1. Since CE at main site sees all the remote sites "coming" from provider's PE, how can you handle traffic shaping/policing issues on this main site CE?
2. Do you use MQC based on destination IP to apply shaping/policing configs on the CE-PE interface?
3. Is it necessary to even bother with this question?
Thank a lot.
David

BGP contains a multitude of knobs which allow a SP to control the traffic sent on one PE-CE link as opposed to the other. One can also make use of the Link Bandwidth extended community to control how traffic is distributed among multiple egress PE-CE links.
The VPN scheme is of course compatible with the use of traffic engineering techniques (RSVP-TE based or otherwise) in the backbone network.
A PE may support additional QoS support by means of one or more of the following methods:
-i. One COS per PW End Service (PWES), mapped to a single COS PW at the PSN.
-ii. Multiple COS per PWES mapped to a single PW with multiple COS at the PSN.
-iii. Multiple COS per PWES mapped to multiple PWs at the PSN.

Traffic Shaping - can't get it to work

Hi
I’m attempting to create a basic traffic shaping policy in a lab environment but I can’t seem to get it to limit the download rate?
I can successfully achieve this with policing. I am testing the speed restriction using a broadband speed testing website, policing is clearly impacting the download rate, this is not the case with shaping. Please see below the shaping and policing policies, which I am attaching in turn to the vlan1 interface outbound.
Further I have messed around with the below shaping policy and set a fixed cir as in the policing policy but it still has no impact on the download speed.
Finally class SLOW_PC under PM POLICE matches an ACL matching traffic to and from a particular IP address. The speedlimiter is matching all traffic
Policy Map speedlimiter(Shaping)
    Class class-default
      Average Rate Traffic Shaping
     cir 1%

any help appreciated

Shaping and policing can both can be used for outbound traffic on an interface, but only policing can be used for inbound traffic. If you're trying to use shaping (which works by managing the queue) on inbound traffic (which has no manageable queue) it will have no effect. Policing is the only option in this case.

Can Anyone Help Me Configure My Verizon (D-Link) DSL-2750B "Traffic Shaping" (QoS)?

Well ... I just spent a wonderful hour and a half (not) bouncing around VZ technical support, etc. trying to get assistance regarding configuring my DSL router.* Between the low-quality Skype connection to India and my lack of success, I'm a little bummed out right now.
Could one of you perhaps help me? I'm trying to configure a single, wire-attached network node (port 4 of the router) so that it can only consume up to 320 Kbps of my 750 Kbps (7.5 Mbps) DSL bandwidth ... no matter what. This results from this node consuming virtually all of the circuit's bandwidth when streaming or during bulk file transfers.
I have tried to remedy the problem using priority with no discernible impact.
The Quality of Service (QoS) element called Traffic Shaping (Services | QoS | Traffic Shaping), described on Page 51 of the VZ DSL-2750B User Manual , appears to be the ideal solution to my problem. Repeated attempts at activating this QoS have all resulted in no throttling of bandwidth consumption.
My most recent attempt was to define the device on Port 4 as the DMZ host ... and then apply a new rule (320 TX, 320 RX) to this interface. Again, no joy.
Does anyone have any experience with this service on this router?
Am I chasing my tail trying to configure the router without validating that my circuit is not configured with "Fastpath (PSE) inactive"?
If the circuit configuration is a potential problem, which office should I ask for at VZ customer service?
Here is the information from the System page of the Router Control Panel:
Gateway ID: PX2M1BC000000
Software Version: 5.4.12.1.44
Release Date: Feb 19 2012
Platform: D-Link DSL-2750B
Board Tag:... Ntag-5_4_12_1_44
Compilation Flags:... LIC=/home/bat/bat/dlink_bcm96328_5_4_12_1/20120219_1343/conf/jpkg_bcm9636x_dlink.lic CONFIG_RG_PROD_IMG=y DIST=DLINK_DSL2750B
I'll note that the Router provides a notification that "RX QOS might not operate when Fastpath (PSE) is active" when I update the router configuration page concerning Traffic Shaping. Because Fastpath is not mentioned in the User Manual, I'm guessing that Fastpath (PSE) might be a configurable attribute of the circuit servicing my PoP, but I have no idea if this is the case.
I searched for relevant messages on this board ... without success. If this has already been addressed, please provide a link, and accept my apologies. (My Google-Fu tends to be weak.)

The asterisk in the first post refers to the following summary of events:
10:40 - Attempt to solve my configuration question using VZ chat begins.
10:49 - VZ chat agent Danish refers me to phone support. (Chat ID number is 020813176471 if you're with VZ and are interested.)
10:50 - Call VZ phone support.
11:02 - Talk with Angel. Because she has not heard of, nor received training in, "traffic shaping," she says my question about configuring this VZ DSL modem must be addressed by "Premium Technical Support." She transfers me.
11:13 - Talk with Pamela. Premium Technical Support only responds to questions about 3d party products. Because my question concerns a VZ DSL modem, Basic Technical Support is responsible. She transfers me.
11:17 - Talk with Joe. He says either the vendor (D-Link) or premium technical support is required. Because I had already tried with D-Link (they referred me to Verizon, as this modem was built exclusively for VZ), I explained what I had already experienced, and described how I wanted "assistance configuring my VZ DSL modem, specifically a feature described on page 51 of the User Manual." He transfers me.
11:23 - The automated phone system asks for my 12-digit customer ID. I wasn't able to find it fast enough, and rolled through to Financial Services. Eventually Trig picked up, listened to my story, and transferred me to "Technical Support" providing the direct dial number, just in case (866.945.79xx).
11:32 - Entered the phone queue. Lots of hissing and clicks.
11:35 - Talk with Monika. (The voice clarity from this point onward was on the order of 1st-generation Skype. Between the horrible language problem -- Monika is in India don'cha know -- and the lousy line quality, this was the most frustrating.) No matter what I said, I couldn't convey the reason for my call. I asked to talk with a supervisor, which Monika related was not possible. She also related that she could not transfer me to an American POC or supervisor.
12:01 - Hung up the phone ... and started down the path that led to my post immediately above.
I was repeatedly queried about the account name and number throughout the process. Conveying this information was especially challenging during the Indian call segment.

=====================================================
Hi everyone,
In the above configuration, I configured traffic shaping to shape the syslog traffic to certain limit. My question is, Can I apply traffic shaping to perticular traffic ? What will happen to the remaining traffic ? We have ethernet hand-of to provider but total bandwidth we can use is 8M, which is controlled by ISP. We just send all the traffic without any shaping.
Thanks

Traffic shaping only works from the source. there is no way (other than policing - i.e., discard) to shape through the cloud.
If you tried to pace the traffic through the cloud, it's got to be buffered somewhere, causing latency, and ultimately discarded frames after the buffers fill.
Policing allows the traffic through until some threshold occurs (traditional frame = DE set at Bc, discard at Be), then the traffic is dropped.
FWIW

Traffic shaping for the Mac

Some routers offer a traffic shaping option to keep uploads from slowing down downloads on asynchronus connections. The Airport Express doesn't? Any software to do it on the Mac?

No the AirPort Express (AX) does not have this feature.
Any software to do it on the Mac?
Of course that would only affect traffic to/from that one specific Mac. You might want to take a look at IPNetTunerX.

Traffic-shaping for delay sensitive traffic

Hello, I would like to verify the use of a traffic-shaping policy within an MQC. I was told that you need to apply a shaping policy in order for QoS to always be engaged and not simply during times of congestion. This apparently is critical when you have apps like VoIP.
On a similar note, i remember reading up on Ciscopress that you might NOT want to subject VoIP to any form of Shaping as this introdues delay and can cause Jitter.
Below is a sample config. If you can post an authoritative source on CCO that explains this I would greatly appreciate it.
Regards,
-Mike

I was told that you need to apply a shaping policy in order for QoS to always be engaged and not simply during times of congestion.
Nope.
You only need to shape when you're dealing with a path where you know the end-to-end bandwidth is less the the egress interface's physical bandwidth and where you cannot manage congestion further downstream along the end-to-end path.
On a similar note, i remember reading up on Ciscopress that you might NOT want to subject VoIP to any form of Shaping as this introdues delay and can cause Jitter.
Semi-true.
The problem can be mitigated by decreasing the shaper's Tc. Also, if shaper doesn't account for L2 overhead (and I believe many do not), you'll need to shape "slower" than the nominal bandwidth. The major problem with the latter, L2 overhead varies, as a percentage, based on packet size. So, you can either allow for worst case, which will best guarantee VoIP service, but tends to give up much of the available bandwidth, or you can shape for average case, which will make VoIP latency and jitter more variable but usually not so much to exceed its service requirements.
You can also bypass shaping for some traffic, but then you need to shape all your other traffic even slower to guarantee the non-shaped traffic bandwidth is always available. As you're effectively reserving this bandwidth, it then becomes unavailable for your other traffic even when unused.
An example of the latter:
policy-map QoS-Policy
class preferred
bandwidth remaining percent 40
random-detect dscp-based
class missioncritical
bandwidth remaining percent 39
random-detect dscp-based
class trans-apps

police 512000 conform-action transmit exceed-action drop
class class-default
shape average 1950000
service-policy QoS-Policy
interface Serial0/0/0
service-policy output shape-20MB
NB: BTW, the above doesn't account for L2 overhead, and I wouldn't recommend it for other reasons, but it should show how you can bypass the shaper.

Traffic shaping combined with queuing

Without any traffic shaping, queuing(ex: priority or custom) is only invoked when congestion occurs... correct?
When FRTS shaping is used and custom queuing also specified, is the queuing only invoked when traffic exceeds the shaped speed, or is it always used? ie: If no other traffic present, would traffic specified to use only 50% of shaped bandwidth use 100% of the shaped bandwidth?
When GTS is used with a GROUP specifing an ACL, is matching traffic always limited to the shaped amount, even if no other traffic on the line? Could non-shaped traffic dominate the line or is GTS-shaped traffic guaranteed the minimum amount?

1. when you have traffic shapping and the limit
for the shaped value is exeeeded, all traffic arriving at the interface with
no token in the token bucket is queued using the configured queue to thier appropriate queue..
hence any type of queueing is not invoken unless some sort of trafiic conjestion exist either
via shapping or otherwise.
2. If you have a granular shaping instruction per protocol per bandwidth. The traffic over
its shapped value would be queued and sent at maximun shape rate configured. ( that's one of the uses of shaping, to trim rate at which
a specific traffic is sent). If its just queuing that is enable not shaping, then
a traffic for a specific queue can use as much bandwidth as availabel when there is no other traffic, hence no congestion.
3. if you have shaped and non-shaped traffic on an interface using GTS, the shaped traffic can use as much bandwidht as the maximum of the shaped
value while not-shaped traffic will also use bandwidht on as see bandwidth without the need to be controlled, however non-shaped traffic will use
all the bandwidht it needs till the interface start droping packet but the shaped traffic would be queued till there is enough token to start outputing
from that queue. if the there are non-shaped traffic, it could be possible that they may overwelm the interface
and prevent even shaped traffic from geting enough bandwidht to the shaped value.

Traffic shaping: Which is the best solution?

Hi! I'm running 3 computers on 1 d-link router, 2 of them has an archlinux installed. Wondershaper mostly works for me when the other computers has cfosspeed running on windows, but when both computers run archlinux and wshaper and p2p applications, ping is over 1000ms instead of 10-20ms.
Which is the best solution of traffic shaping on linux, and is there a howto for them (can be even a gentoo wiki page or similar)?
Edit: shorewall is not being built from yaourt (x86_64), can't find a usable manual for trickle and niceshaper, (even ubuntu forums has unreplied "threads" about it) and can't start them coz missing config files, it seems, noone cares about ACK priority and ping in the Linux world
Last edited by Vegita (2010-02-24 19:58:07)

This config file is being used on 2 computers, and not working, my speed is 8m/1m. Any ideas? I don't want to limit anything, I just want ACK's priority to set to the highest, and same with http, and get p2p apps (opn this computer ktorrent and valknut, on the other ktorrent) priority on lowest. valknut's port is 1412, ktorrents' one is 6881 on this and 24748 on the other computer. Any ideas what to modify for small ping?

QoS Traffic shaping and peak shaping

Hi,
Could somebody tell me what is the difference between traffic shaping and peak shaping?
Kind Regards.

Standard traffic shaping (the shape average command) will keep the average rate of the traffic to the limit you specify, which should be the committed rate of your circuit.
Peak shaping will also do traffic shaping (using queues, etc), guaranteeing a minimum rate, but will allow traffic to levels to burst above your configured (committed) rate.
From the documentation:
Traffic shaping limits the rate of transmission of data. In addition to using a specifically configured transmission rate, you can use Generic Traffic Shaping (GTS) to specify a derived transmission rate based on the level of congestion.
You can specify two types of traffic shaping; average rate shaping and peak rate shaping. Average rate shaping limits the transmission rate to the CIR. Using the CIR ensures that the average amount of traffic being sent conforms to the rate expected by the network.
Peak rate shaping configures the router to send more traffic than the CIR. To determine the peak rate, the router uses the following formula:
peak rate = CIR(1 + Be / Bc)
where:
â¢Be is the Excess Burst size.
â¢Bc is the Committed Burst size.
Peak rate shaping allows the router to burst higher than average rate shaping. However, using peak rate shaping, the traffic sent above the CIR (the delta) could be dropped if the network becomes congested.
If your network has additional bandwidth available (over the provisioned CIR) and the application or class can tolerate occasional packet loss, that extra bandwidth can be exploited through the use of peak rate shaping. However, there may be occasional packet drops when network congestion occurs. If the traffic being sent to the network must strictly conform to the configured network provisioned CIR, then you should use average traffic shaping.
Examples
The following example sets the uses average rate shaping to ensure a bandwidth of 256 kbps:
shape average 256000
The following example uses peak rate shaping to ensure a bandwidth of 300 kbps but allow throughput up to 512 kbps if enough bandwidth is available on the interface:
bandwidth 300
shape peak 512000

Packet filtering and traffic shaping during peak h...

I play the online game World of Tanks and an currently exteriancing severe lagg and disconnects, the problem does not appear to be with the game/service provider but with BT, i need to know does BT use "packet filtering" and "traffic shaping" during peak hours and if so why has it suddenly started.
This game use's P2P to keep the latency down for players so have been advised to contact BT and ask them are they limiting these types of connections.
Most games do not use these types of connections, but World of Tanks one does and again,been told BT just don't like them, due to the amount of connections they attempt to forge in order to have a stable latency.
I need to know if this is going to continue as pay to play the game, therefore would have to consider changing my ISP to virgin who dont use "packet filtering" and "traffic shaping" during peak hours .
Quick advice would be appreciated.

It's absolutely horrible. i turned off wifi all other devices and every other open program just to reduce my latency for 120ms to 80ms.
Still suffer from huge packet loss.
It would be absolutely horrible if they have started throttling worldoftanks.eu servers. Phone support is no help all they torld me to do is restart my router
I hope this is fixed soon. There are many posts on the WoT eu official forums and everyone that is effected appears to be a BT customer.
Some have mentioned it could be the damaged undersea cable.
I don't have any problems with torrents being throttled or anything like that. only worldoftanks.eu being throttled.

I see a "Shaping Active no" there, which doesn't sound good.
I am definitely missing something.
Any help is appreciated, thank you.

Hello Adrian,
there is one strange thing in your show/config given:
class-map match-all match-smtp
match protocol smtp
----snip----
Class-map: match-smtp (match-all)
59977 packets, 83502451 bytes
5 minute offered rate 0 bps, drop rate 0 bps
Match: access-group 2
----snip----
Why does ACL 2 show up int the show policy-map command, when you have configured NBAR (match protocol smtp)?
Are you sure those two outputs are from the same router with the same config? Can you please highlight the underlying reason for this inconsistency? If not a reboot might help ...
Otherwise you might also leave away the Bc and Be values and just take "shape average 640000".
Hope this helps! Please rate all posts.

Skype for business traffic shaping

Good morning,
I would like to implement Skype Business in my company. We are an international company with contacts in India, Tanzania, Canada and so on... so normal Skype connections are really bad in some countries because of the bandwith they have.
I have seen the reviews of Skype Business, my question would be, how can i implement a nice traffic shaping for setting up all? I have access to all hardware in all the offices we have but i would need more help about
Thanks in advance,
Kind regards
Celia Espinosa

Hello Celia,
I see you are wanting to implement Skype through out your network for making calls via Skype. This is very easy to do, as long as you have Internet access at all locations. The only thiing I see is that the Internet Connections you have may not be up to our standards.
The first thing that needs to be done is to run a Traffic Study in each location to determine the quality of the Internet Connection you need. The simplest way is to run a Voxygen test at each site. You can have someone at each site log into Voxygen at https://tools.voxygen.co.uk and run the Network Compability Test for Skype. This test will display results after each test to give you recommendations on what you need to have to connect to us. It will test for up to 50 Channels.
The next action is to determine what type of equipment you will need at each location. For that answer, you should contact your IT department for recommendations.
If you need PBX's or any other type of equipment, Skype can make recommendations via our web site. http://www.skype.com/intl/en-us/business/skype-connect/
From there you will need to have a Telecom person help you implement your network to connect to Skype. Start small to test, then build from there.
I hope we have answered some of your questions to get you started with Skype Connect. We are here for your support, so come back anytime.
Thank You for considering Skype and using the Skype Community Forums.
Regards,
Victor S.

Application has problems when migrated from 10g to 11g

Hi there,
I am hoping someone can shed some light on a problem I have in moving an application from Oracle 10g to Oracle 11g. The app works fine on 10g (uses Apache webserver with PL/SQL module, and APEX 3.1.2.00.2), but on 11g using the embedded web server and APEX 3.2.0.00.27, it doesnt. Most of the app works fine, but there are a couple of pages that provide the ability to add child rows to a parent/child relationship, where the parameter passing mechanism from one page to the next appears to suffer from some sort of corruption. I have traced this using the "session" and "debug" buttons on the developer interface, which show that the values of the parameters get changed inexplicably, when branching from one page to the next - even when the page is actually branching to itself.
I am using the "Set these items, "With these values" fields in the branch, and have verified that the correct values are being associated with the correct items in the application builder. But while this does work correctly under 10g, with 11g, the wrong values end up being passed. Just prior to the branch the set of parameters have the correct values, but immediately after the branch, one of the values is NULL, another has the value of a different item, and a third has a totally random value - I have no idea were it comes from!
I migrated the application from 10g to 11g using the APEX application developer's Export/Import options. There have been no other changes. Should this have worked? If so, any ideas what might have gone wrong?
Thanks,
Sid.

Well, I managed to solve this, but not in a way that makes much sense.
In desperation (I had tried almost everything else!) I changed the value of "Cached" in the page settings from "No" to "Yes", and ran the app, but the page didnt render correctly (in either Firefox or IE7) - in fact all that displayed was the developers toolbar at the bottom of the page. I changed the value of "Cached" back to "Y", ran the app again, and hey presto - everything worked fine! I actually did this a second time with a fresh import of the app from 10g, just to be sure I wasnt seeing things. I wasnt!
There was just one further issue - everything worked fine apart from this section of code in a page process:-
ELSIF (:p9_filter_type = 5) THEN
IF (:p9_x_gene_list IS NOT NULL) THEN
:p9_filter := :p9_x_gene_list;
END IF;
:p9_entity_types := 'GENE';
END IF;
In 11g the value of :p9_entity_types was not being set to 'GENE' when :p9_filter_type was 5. This was (and still is) working in 10g. I changed the code as follows:-
ELSIF (:p9_filter_type = 5) THEN
:p9_entity_types := 'GENE';
IF (:p9_x_gene_list IS NOT NULL) THEN
:p9_filter := :p9_x_gene_list;
END IF;
END IF;
... and now it works fine in 11g as well.
Only wish I knew why!
