Web Hosting Talk : Other Forums : Computers and Peripherals : Need to implement traffic shaping on Home Network

[Gary4gar]

Hi,
I have a small network at home which has hybrid of PC,Laptops and phones over Ethernet & Wifi. there are about 4desktop,5laptops & 2phones with wifi. they all share internet connection. here is my network disgram:

http://thumbnails31.imagebam.com/844...9084404907.jpg

the problem is, if some family member is running torrent or watching youtube. it makes impossible to browse which irritating.



Here is what I am looking to do:

DNS - Priority 1
HTTP/FTP/SSH/SMTP/POP3 - Priority 2
VIOP with Skype - Priority 3
Torrents and youtube - lowest priority

So I searched and it turns out my router(Dlink GLB502T) does support QOS. It has three algorithms 1) HTB Queue Discipline 2) Low Latency Queue Discipline 3) PRIOWRR. What I don't know which one is for me. so I need your help implementing it.

The demo Interface of my router is here:
http://sluzby.volny.cz/img/navody/za...demo/index.htm

It has three parts
1) Shaper Configuration
2) EGRESS
3) INGRESS

Any Networking gurus, please help. All these terms like COS1,Cos2,HTB,PRIOWRR sound alien to me

That is a weird QOS interface most routers look like:
QOS Setup --
Enable QoS Enabled
Queuing Method Priority Queuing

IP TOS(Type of Service) Features
Process TOS Field Enabled
Overwrite Policy Priority Yes

QOS Policy --
Policy Name
Source Address
From To , , ,
Destination Address
From To , , ,
Protocol Type
Source Port From, To
Destination Port From, To
Priority Queue high,med,low

Did you try help? I was able to figure it out after clicking on help (did not spend much time though)... other stuff you could more than likely contact TI or search the web. You should be able to play with it and get it right... some of the functions did not work (dead links) so I was not able to look at some pages... but I'm thinking this will not be that difficult once you sit down and learn the terms of this device.

Here is the help:

The QoS framework allows network administrators to configure the router to meet the real time requirements for voice and video. For a complete solution the QoS framework is supported on both the Ingress and Egress interface. The QoS Framework supports the following domains:-
1. TOS
2. DSCP
3. VLAN
4. WME (WLAN only)
To support these domains the QoS Framework introduces a virtual concept of Class of Service(CoS).There are six levels of service available named and prioritized as follows:-
CoS1 > CoS2 > CoS3 > CoS4 > CoS5 > CoS6

The network admin needs to define Ingress TCA that maps the Domain to CoSx. The framework also allows the ability to classify packets on the basis of the type of data. Currently the following fields can be used to classify packets:-
1. Source Mac Address
2. Source IP Address/Source Net
3. Destination IP Address/Destination Net
4. Source Port (Range is supported)
5. Destination Port (Range is supported)
6. Protocol
Once a packet has been classified on the Ingress the network admin needs to configure the Egress to do the reverse i.e. CoSx to Domain Mappings.

The QoS Framework also provides the following shaping algorithms:-
1. PRIOWRR
This is a priority based WRR algorithm operating on CoS2-CoS6. CoS1 queues are highest priority and are not controlled by the WRR algorithm.
2. Rate Based Shaper
The PRIOWRR algorithm does not account for the packet size. This algorithm rate shapes the traffic of a class over a specific interface. All CoSx traffic is assigned a specific rate to which data will be shaped to. Example: If CoS1 is configured to 100Kbps then even if 300Kbps of CoS1 data is being transmitted to the interface only 100Kbps will be sent out.
3. Low Latency Shaper
This is similar to the above algorithm except that CoS1 is not rate limited. So in the example above CoS1 data is not rate limited to 100Kbps but instead all 300Kbps is transmitted. The side effect is that a misconfigured stream can potentially take all bandwidth.
