QoS (Quality of Service) ??

Can anyone explain to me what this is? Twice when ordering BT Vision the sales people have not added this to my account and consequently this stops the service from working and errors, both times it has taken numerous phone calls before they have realised and added this!

Guilbo advised
The ADSL speedtest does a download test and an assured rate by default. The ADSL2(+) test does a download test and an upload test by default, but will also do an assured rate test if you have recently had an active QoS session. You can see it by playing a video, stopping it and then immediately doing a speedtest. You should see 3 test results
Re ADSL2+
Yes I got that immediately after an active QoS session

Changing Quality of Service in Receiver Adapter

Hi,
We have a scenario where hundreds of messages for the same interface is sent to XI and written to one file on the receiver side. We do not want to change the QOS (Quality of Service) to EOIO (Exactly Once in Order) on the sender side nor do we want to use BPM due to performance issues.
Is there any way to change the QOS to EOIO after the mapping is complete?
I tried changing the QOS (DeliverySemantics) using a adapter module on the receiver adapter. In the audit log, I can see that the QOS has been changed to EOIO and assigned to the correct ConversationId, but the messages does not follow the EOIO process.
Any help is great appreciated.
Thanks.
Best Regards,
Duke

Here is more detail on the scenario.
Hundreds of messages come into XI from R/3. One message is split into multiple messages by using the Extended Interface Determination. These messages are written to a file (each message has its own file). The file adapter is set to append.
The issue we are facing is that when hundreds of messages are processed simultaneously, it triggers an error when attempting to write to the file (locking issues). It then has to wait and retry, which adds to total processing time. Due to the time sensitivity of these interfaces and the errors that are raised, we would like to change the QOS to EOIO on the receiver side (when it writes to the file) so that it does not have to wait and retry.
The Maintain Order at Runtime is checked in the Interface Determination. Once it gets to the adapter framework to write to the file, it has a QOS of Exactly Once, which is carried over from the sender.
We do not want to change the QOS on the sender side, but only on the receiver side.
Any thoughts?
Thanks.
Best Regards,
Duke

Hi,
"Quality of service (QOS) is disabled in the HTTP service. Unable to turn on QOS features." this message is seen and server restart itself. Why this occur?
Thanks..

That message is logged when you have QOS disabled. Check http://docs.sun.com/source/817-1831-10/agsnmp.html#wp999778 for information on enabling QOS.
However, the server should not crash/restart. Please describe the steps to reproduce the problem.

Quality of Service and Jitter issues

I am having poor quality of service (36%) and Jitter issues (36ms). I called Verizon Fios technical support and was told that my connection is fine and that it must be a vendor issue. Only vendor I'm having an issue with is Verizon. If I can't get someone from Verizon that knows what QoS and Jitter is on the phone to help me troubleshoot this issue I'm going to have to cancel my service and find a provider that has someone technical providing tech support.

Quality of Service with WRT610N and Vonage

I'm trying to get Quality of Service working with my WRT610N and my Vonage device. The WRT is connected directly to my cable modem, and the Vonage device is connected to Ethernet port 1. I've set up the Vonage's MAC address on the QoS tab to be priority "High" (done by selecting the "Voice Device" on the Category dropdown). Additionally, I've set my Vonage options (on the Vonage website's page for my account) to use the highest bitrate (90 kbps, I think). No other QoS settings have been made.
However, the router doesn't seem to be enforcing QoS at all. If I do any kind of surfing at all (dragging around on Google maps to load new satellite pages is a good test), the voice quality on an ongoing Vonage call becomes very choppy. Do I have to do something else to ensure that the Vonage device gets highest priority?
Solved!
Go to Solution.

Yup, it should work. Been working with these devices lately and the only way to get a good connection from it is by connecting the Modem and the VONAGE then your router. COMCAST is alsready using smart modems so it should always recognize any devices connected to the modem. You can also try leaving the devices OFF for a minute and turn ON the devices, first the modem and wait for another minute then your VONAGE and wait for another minute and then your router.
Please post if it worked on not...

Change "Quality of Service" EOIO to EO for a XI Purache Interface in EBP

Hello Colleagues,
we have a PO interface in place but some problems with Message processing at Adapter. To solve the problem we try to change the Quality of Server EOIO to EO but the Quality of Service comes from the EBP system at XML Message header.
Please, in that location on the EBP system are we able to change the Quality of Service?
Many thanks in advance!
Jochen

Hi Barry,
The EBP system send POs (also calalog messages) via integration engine (SXMB_MONI on EBP) to the XI system (Integration Server) and the XI system sends the messages out to the Vendor via SOAP.
The messages which are send by EBP are with QOS EOIO at message header.

Jochen

EOIO Quality of Service

Hi guys,
We have developed a File-XI-Idoc scenario, which works fine.
The problem is that we want each file that is found in the folder where XI reads files, to be processed first and the corresponding Idoc that is produced from the mapping to be posted in receiver R/3 system first.
In order to achieve that we have used EOIO QoS in processing parameters of sender file communication channel. Although, files are processed by XI one by one, since they are put in the same queue, it is not guaranteed that Idocs are posted to R/3 in the same sequence,
We had a case that Idocs were posted exactly at the same time in receiver R/3 system and the one that should be processed second was processed first. The second Idoc (that should be processed first) was locked due to concurrent modification of the same material.
Is there something else that I can do in receiver Idoc adapter, for example??
Evaggelos

Use the Queue Processing option of the receiver Idoc channel
Queue Processing
If the function module IDOC_INBOUND_IN_QUEUE is to be used, set the relevant indicator. It is used for IDocs that are serialized by queues (quality of service is EOIO). This module is only available in SAP Web AS 6.40 and higher. If it is not available, the function module IDOC_INBOUND_ASYNCHRONOUS is called. The indicator only takes effect in SAP systems Releases 4.0 and higher. Calls for the queue processing function module are placed in the qRFC queue.

RFC TO SOAP - Quality of Service

Hi,
i see that my RFC to SOAP test functioning properly. But in Exactly Once mode. In RFC Sender adapter and SOAP Receiver adapter there is no configuration tab to change "Quality of service".
Is it possible to change the mode?
Kind Regards,
PM

It is not possible to set the QoS at Channel leve for RFC receiver.
Have a look at this thread: tRFC & qRFC
for SOAP, look at this discussion: Re: In what QOS does the receiver SOAP adapter work BE or EO?

Quality of Services "Exactly Once in Order"

Hi,
I have several integration using iDOC output R / 3.
This integration into the Integration Builder them removed brand "Maintain Order At runtime" (Quality of Services - Interface Determination) to be executed in parallel, but when they reach the engine J2EE appear with the Quality of Services as "Exactly Once in Order."
Why this happens with iDOCs? . With RFC do not have this problem.
Best Regards
Julian.

Hi
I have been reviewing the integrations that run in parallel and gave the impression that really do not run in parallel (Quality of Services "Exactly Once"), but that the channel receiver is taken so that the previous interface ends of inserting data into the receiver.
If open the message and revise the log, the first message that arrives is in this state:
"JDBC adapter receiver channel JDBC_XXX_YYY_Receiver: started processing; Party, service ZZZ_BS "
But the following is not enough to reach this state and it is with this log:
"Receiver JDBC adapter: started processing; QoS required: ExactlyOnce "
One step before the first message, only runs the next step when the first message ends to be processed by the adapter.

How to determine quality of service of communication between XI and R/3

Hi All,
Suppose we are sending data through R/3 to XI using outbound abap proxy to XI. My query is how do we determine which quality of service (EO or EOIO) will be used for this communication. I have seen normally it is EO ( or BE, in case we are using execute_synchrounous function).

How to deal with stuck EOIO messages in the XI 3.0 Adapter Framework
EO = Exactly Once ( Used in Asynchronous Communication)
EOIO = Exactly Once In Order ( Used in Asynchronous Communication)
BE = Best Effort ( Used in Synchronous Communication)
Best Effort --> Used for Synchronous Calls.
EO and EOIO --> Asynchronous Calls.
EOIO --> Asynchronous with Sequential Processing Guranteed.

For receiver channels QoS BE (Best Effort) will result in a
synchronous call (sRFC) , QoS EO (Exactly Once) will create a
transactional call (tRFC) to the BC. For sender channels a synchronous
call (sRFC) will result in a message with QoS BE, a transactional call
(tRFC) will result in a message with QoS EO.
QoS EOIO is not supported by the BC-Adapter.
SAP XI term Quality of service describing how the transmission and process-ing of messages is to be handled. Possible values are:
BE = BestEffort (synchronous call, no transactional guarantees for transmission and processing)
EO = ExactlyOnce (asynchronous call, guarantee for local transactional handling, exactly-once transmission and exactly-once processing)
EOIO = ExactlyOnceInOrder (as for EO but with serialization guarantee on a given queue name).

Telstra Gateway Max aka Technicolor TG799vac lacks basic Quality of Service

Hi, I have recently moved to a plan that included the Telstra Gateway Max for free, and have also recently opted-in to Telstra Air which I think is wonderful. Problem. These Technicolor TG799vac modem/routers which Telstra is providing (are actually a very high quality, highly finished product), are missing 1 key feature. My plan also came with a free T-Box which I can watch Foxtel on T-Box, Presto, Bigpond TV, Bigpond Movies, and other great content. Except the Gateway Max does not have even basic "QoS" features. QoS is an acronym for Quality of Service. It provides that certain traffic on your local network can be marked as a higher priority than other less important content. For instance. VoIP (Voice over IP) usually has #1 priority, usually followed by video, and then other content like HTTP (normal downloads) and Bit Torrent etc are all just normal quality. https://en.wikipedia.org/wiki/Wireless_Multimedia_Extensions "Wireless Multimedia Extensions (WME), also known as Wi-Fi Multimedia (WMM), is a Wi-Fi Alliance interoperability certification, based on the IEEE 802.11e standard." "It provides basic Quality of service (QoS) features to IEEE 802.11 networks." "WMM prioritizes traffic according to four Access Categories (AC) - voice, video, best effort, and background. However, it does not provide guaranteed throughput. It is suitable for well defined applications that require QoS, such as Voice over IP (VoIP) on Wi-Fi phones (VoWLAN)." This WMM standard is a highly important standard for modem routers because if I'm downloading some random large file on one computer which consumes all available bandwidth (speed), my T-Box instantly degrades and becomes unwatchable. My plan comes with unlimited calls anyway plus my mobile comes with unlimited calls on a Telstra competitor so I don't personally have any use for VoIP. My main concern is the lack of Quality of Service for video content. Given we now have Telstra Air I do wonder what happens when a guest user consumes all available bandwidth (speed) is that going to affect my T-Box negatively? I understand there is QoS built into Telstra Air such that the guest user cannot hog all your bandwidth (preference is given to the host customer over the guest customer) however that's as far as QoS goes with Telstra. I would urge Telstra to pass this post to their development team for consideration, because as it stands the only way for people to get QoS is to buy other non-Telstra modem routers. I can still probably plug Telstras Gateway Max into another modem router that does support QoS which is what I intend to do to solve the problem, but if they could look at addressing this issue the Gateway Max would be a very ideal, very professional modem router that I could recommend to everybody and not bother with the hassle of buying other non-Telstra modem routers.

Telstra Air has built in QoS, there is a specific speed threshold that they can't pass. If your internet speed is too low it won't allow allow fast access to clients.
The real truth is all those features are available on your modem but have been disabled by Telstra's firmware, Telstra wants to manage all of these areas so sadly there is nothing we can do

Quality of service

I had internet services with verizon when i lived in new york and i absolutely loved it. The service was the best, the customer service was excellent. Now that I have moved to the Atlanta metro area there is no available coverage from you in this area. Are you planning on providing services in this area at anytime in the near future? If so you definitely will not have any competition, because the quality of service is horrible by all the providers in this area. HELP!

I have not hear of Verizon (other than wireless) in Georgia at all....

Setting Up Router Quality of Service

I need to set limits to specific IP's or devices in my house using the internet. I heard that "Quality of Service" on the router was the best way to go. I checked it out on my router but it is very confusing. I have no idea how to set this up and I work with computers for a living. Can anyone help me configure this?
