Communications Server 2010 introduces DNS load balancing, a software solution that can greatly reduce the administration overhead for configuring load balancing on your network.

DNS load balancing balances the network traffic that is unique to Communications Server, such as SIP traffic and media traffic. Although you will still need hardware load balancers for your server pools, their setup and administration will be primarily for HTTP traffic, which the administrators of hardware load balancers are accustomed to.

If you choose to deploy DNS load balancing, your organization’s administration overhead for hardware load balancers will be greatly reduced. Additionally, complex troubleshooting of problems related to misconfiguration of load balancers for SIP traffic will be eliminated. It also ensures that hardware load balancer problems do not impact SIP traffic, such as the basic routing of calls.

DNS load balancing is supported for Front End pools, Edge Server pools, and Director pools.
