Bandwidth Arbitrator

The ArbiQos release is a new product which makes use of many of the Linux Bandwidth Arbitrator technology.

- Reserves bandwidth on your network for real time
services so that your VOIP traffic remains high
quality

- Works with your existing network hardware and
routers no need to upgrade your network to run VOIP
traffic.

- Adminstration is through a web gui and takes just
minutes to configure.

The Arbiqos system is specifically designed as a turn key utility that will dynamically reserve bandwidth for your real time traffic running over shared data links. The unique technology allows you to control bandwidth allocation with only one active unit on a link.

This is a beta release and we welcome beta customers (we will support at no charge)

Here is the basic text for the howto for this release.

Installation no changes. Just follow the Bandwidth Arbitrator How-To to get your kernel ready

The Arbiqos1.0 release supports the following commands
FOR NEWER RELEASES PLEASE GO TO THE BOTTOM TO SEE THE CHANGES

MODIFY_CONFIG (parameters only no shaping rules)

ADD_CONFIG (masks and priority hosts)

REMOVE_CONFIG (masks and priority hosts)

The arbiqos system is a smart solution that will insure you have bandwidth available for high priority real time streams such as VOIP and video.

You configure the arbiqos system as follows.

1) Locating the arbiqos system on your network

Decide where your network choke points are, these would be links in your network where your VOIP or Video traffic must pass , and obviously a network link that also carries lower priority data traffic

2) Identify the IP addresses of your source nodes for real time traffic. In a VOIP system this could be the IP address of your VOIP switch, or the voice endpoints (phones) you do not need both. It is always easier to give the IP address of a centralized switch than all the leaf nodes if you have such a configuration

3) You need to know how much bandwidth each stream typically requires (bi directional total) convert this number to bytes per second.

4) Enter each IP address of your VOIP endpoints with the following command

ADD_CONFIG HOST PRIORITY x.x.x.x 1

5) Set the value for the size of these streams

MODIFY_CONFIG PARAM PRISIZE

6) Place the arbitrator(s) in the choke points of your network

The arbitrators will constantly monitor the IP addresses you configured for real time traffic, as more of these streams come on line the arbitrator will dynamically scale back all other traffic. When your streaming traffic is light the data traffic will be allowed more bandwidth.

ARBIQOS 1.1 CHANGES
The changes in commands (for arbiqos1.1)

The ADD_CONFIG command for HOST must have a port field
, the last field , use 0 to specify don't care.


./ADD_CONFIG HOST 63.241.20.163 PRIORITY 0


The above command will make 63.241.20.163 a priority
host  on any port that it appears on, essentially this
insures there is enough bandwidth for this host when
active.

./ADD_CONFIG HOST 10.0.0.1 PRIORITY 80


The Above command will only reserve bandwidth when

there is an active connection on port 80 for host
10.0.0.1


You can have more than one rule per host if you
specify 
different ports for each rule.


Examples for REMOVE_CONFIG



./REMOVE_CONFIG  HOST 63.241.20.163 PRIORITY 80

./REMOVE_CONFIG  HOST 63.241.20.163 PRIORITY 0
