I have had a brief demo as part of a WSD training session. The Linkproof handles DNS for the links and does active delay probing on incoming and outgoing traffic.
>From the Manual: Radware's LinkProof eliminates all of the complexities of multi-homing design, providing a single, easy to manage appliance that intelligently utilizes all Internet links optimally. LinkProof also maximizes the benefits of multi-homed networks that are never fully taken advantage of with traditional designs. The following diagram represents a typical LinkProof configuration. LinkProof provides the following advantages for multi-homed networks: o LinkProof intelligently manages the IP address ranges assigned to the network from various ISPs. o LinkProof ensures that all ISP links are used by intelligently load-balancing all outgoing traffic through the available links, while simultaneously managing the address spaces used for outgoing traffic. o LinkProof's intelligent load balancing uses link availability, link load, and link strength (in cases where various links have differing bandwidths) as factors that contribute to load balancing decisions. o LinkProof uses Radware's already proven proximity detection algorithms to choose the best ISP for outbound traffic, taking into account router hops and latency to the destination network, as well as current load per ISP link. o LinkProof houses an intelligent DNS server agent that can manage the flow of incoming traffic into the network, assuring that all ISP links are used for all incoming traffic and no address from a failed ISP link is ever advertised to the Internet. o LinkProof's proximity can also be used to ensure that the optimal path is used for inbound traffic. In essence, the LinkProof is a single, easy to administer, traffic manager for the multi-homed network, eliminating the complexities of routing protocols and uncertain traffic patterns. It also optimizes the multiple ISP connections of the multi-homed network to ensure that all links are used to the best of their potential, thereby making the entire network more efficient for inbound and outbound traffic.
