MVP Routing™ Network Load Balancing
MVP Routing is the pinacle of link balancing (WAN & Internet Load Balancing)
Network Load Balancing or multi-homing is the ability to aggregate traffic from one or more service providers in order to achieve higher bandwidth speeds and greater reliability through link redundancy and Internet load balancer appliances.

Balancing Algorithm
The Edge Wan & Internet Load Balancer dynamically balance sessions across each active WAN link based on a number of continuously updated metrics. These metrics include: the current utilization rates of each WAN link, the latency found on each link, the number of sessions balanced across each link (including how the most recent session was balanced) and finally administrative preferences entered via the web GUI.
The Edge Wan & Internet Load Balancer can balance from two (2), up to five (5) WAN connections. These connections can be broadband DSL, cable, wireless, satellite or traditional T1 and DS3 connections. The Edge Wan & Internet Load Balancer can manage all flavors of network connectivity, with an Ethernet handoff as the only requirement.
How Does It Work
Using transparent proxy to load balance network traffic across two broadband connections without having to make any IP address changes between the firewall and the WAN1 router.
A common scenario is one where the Edge Wan & Internet Load Balancer is installed into an existing network, which can be done via our transparent proxy technology. Using transparent proxy, the Edge Wan & Internet Load Balancer is placed between the existing LAN network (or firewall) and the primary WAN router (see above). The appliance will pass-through traffic to WAN1 with zero address changes.
The WAN2..3..etc connections can then be added to the appliance and network load balancing is done automatically. Initial configuration can be completed in less than 15 minutes.
The Edge platform is well suited for replacing existing firewall devices when performing network load balancing while at the same time increasing overall network security.
Another common deployment is one in which the Edge Wan & Internet Load Balancer is replacing or becoming the firewall for the customer. With a modular enterprise class stateful inspection firewall [ ICSA compliant ], many organizations choose to use the firewall functionality in order to simplify their overall network design.
Additional security modules available include: content filtering (web filtering), intrusion detection and prevention, firewall logging, and DoS protection.
By using static /30 routing or performing NAT both the broadband connections the Edge platform can balance each network connection with creating any potential ARP conflicts.
The Edge Wan & Internet Load Balancer also supports a static routing mode, where either an existing network is split up or an additional subnet is obtained from the WAN1 service provider. In both cases, as with the proxy option above, WAN1 traffic can simply pass-through the appliance with minimal network changes.
