SPBM supports Network Load Balancing (NLB) Unicast and Multicast modes.

NLB is a clustering technology available with Microsoft Windows 2000, Microsoft Windows 2003, Microsoft Windows 2008, and Microsoft Windows 2012 server family of operating systems. You can use NLB to share the workload among multiple clustering servers. NLB uses a distributed algorithm to load balance TCP/IP network traffic across a number of hosts, enhancing the scalability and availability of mission critical, IP based services, such as web, VPN, streaming media, and firewalls. NLB also provides high availability by detecting host failures and automatically redistributing traffic to remaining operational hosts.
