Setup Load Balancing in Wowza Media Server

As we all know that the load balancing helps to spread the workload over network so that the current server do not get oveloaded. This judgement is based on network traffic.

Now this blog will help you to deploy and setup Load Balancing in Wowza Media Server

Requirement :

We need minimum two server(one for Listener and rest are Sender i.e edge server), and both will have its own copy of Wowza Media Server installed.

Load Balancer Server as Listener

One server that will be configured as Lisener Server, will listen all request from sender and provides the least loaded edge server. The server will running the ServerListenerLoadBalancerListener. Load Balancer have all information of its edge server.

Edge Server as Sender

Second server which is Edge server, is configured to use the ServerListenerLoadBalancerSender ServerListener class. Edge servers will send load and status information to Listener server and it will give least loaded server information.

Configuration on Load Balancer Server (Listener)

Configuration need change in wowza configuration file in Load Balancer. Here is the Steps.

Step 1:

Download the Wowza Media Server 2 Preview 7 from this link http://www.wowza.com/forums/content.php?108

Step 2:

Copy the file lib/wms-plugin-loadbalancer.jar from this zip archive to the [install-dir]/lib/ folder of Wowza Media Server 2.

Step 3:

Copy the file conf/crossdomain.xml from this zip archive to the [install-dir]/conf/ folder of Wowza Media Server 2.

Step 4:

Edit [install-dir]/conf/Server.xml and Add ServerListener entry to the list:

Code Snippet :-


        loadBalancerListenerKey
        023D4FB4IS83


        loadBalancerListenerIpAddress
        *


        loadBalancerListenerPort
        1934
        Integer


        loadBalancerListenerRedirectorClass
        com.wowza.wms.plugin.loadbalancer.LoadBalancerRedirectorConcurrentConnects


        loadBalancerListenerMessageTimeout
        5000
        Integer

Step 5:

Edit [install-dir]/conf/VHost.xml and add the following HostPort/HTTPProvider XML snippet just before the HTTPProvider definition for com.wowza.wms.http.HTTPServerVersion:

Code Snippet :-


        com.wowza.wms.plugin.loadbalancer.HTTPLoadBalancerRedirector
        *loadbalancer
        none
        
                
                        enableServerInfoXML
                        true
                        Boolean

Configuration on Edge Server (Sender)

Configuration need change in wowza configuration file in Edge Server. Here is the Steps.

Step 1:

Download the Wowza Media Server 2 Preview 7 from this link http://www.wowza.com/forums/content.php?108

Step 2:

Copy the file lib/wms-plugin-loadbalancer.jar from this zip archive to the [install-dir]/lib/ folder of Wowza Media Server 2.

Step 3:

Edit [install-dir]/conf/Server.xml and make the following changes. Add the following ServerListener entry to the list:

Code Snippet :-


        loadBalancerListenerKey
        023D4FB4IS83


        loadBalancerListenerIpAddress
        *


        loadBalancerListenerPort
        1934
        Integer


        loadBalancerListenerRedirectorClass
        com.wowza.wms.plugin.loadbalancer.LoadBalancerRedirectorConcurrentConnects


        loadBalancerListenerMessageTimeout
        5000
        Integer

Step 4:

Edit [install-dir]/conf/VHost.xml and add the following HostPort/HTTPProvider XML snippet just before the HTTPProvider definition for com.wowza.wms.http.HTTPServerVersion:

Code Snippet :-


        com.wowza.wms.plugin.loadbalancer.ServerListenerLoadBalancerSender

Add the following properties to the  section at the bottom of Server.xml:

        loadBalancerSenderTargetPath
        ${com.wowza.wms.AppHome}/conf/loadbalancertargets.txt


        loadBalancerSenderRedirectAddress
        [redirect-address]


        loadBalancerSenderMonitorClass
        com.wowza.wms.plugin.loadbalancer.LoadBalancerMonitorDefault


        loadBalancerSenderMessageInterval
        2500
        Integer

Where [redirect-address] is the ip address of this machine.

Step 5:

Create the file [install-dir]/conf/loadbalancertargets.txt and add below Code.

Code Snippet :-

# [load-balancer-ip-address],[load-balancer-port],[encryption-key]
[load-balancer-ip-address],1934,023D4FB4IS83

Where [load-balancer-ip-address] is the ip address load balancer server.

Start both server and test these.

Use this Url to test : http://[load-balancer-ip-address]:1935/loadbalancer?serverInfoXML

or

http://[load-balancer-ip-address]:1935/loadbalancer

[Note: Please do not copy the wowza media server installation zip from one server to another because they have used unique guid]
