Radware announces LinkProof: The first IP Load Balancing Solution for networks with multiple ISP connection

To ensure 7x24 availability many enterprises, e-commerce sites and regional ISPs are utilizing multiple Internet router connections. The LinkProof by Radware (Nasdaq: RDWR) is the first technology designed to intelligently load balance IP traffic between these "multi-homed" sites, creating redundancy and eliminating single points of failure.

Deploying independent router connections to two or more ISPs creates these multi-homed sites. This diversity ensures 7x24 availability and an uninterrupted packet delivery to and from the enterprise in the event one or more ISP connection fails. While this adds redundancy, it also creates configuration complexity that may necessitate intricate routing protocols such as BGP (Border Gateway Protocol) and/or coordination between the contracted ISPs.

LinkProof removes this complexity by taking responsibility for the packet delivery through a healthy ISP connection. Sitting logically between the enterprise network and a farm of Internet routers, the LinkProof verifies ISP health and intelligently load balances all inbound and outbound traffic. In addition, it performs Smart NAT to ensure the uninterrupted packet delivery to and from the enterprise network. Smart NAT allows the LinkProof to perform network address translation according to the ISP connection selected to carry the session to the Internet. For example, if the LinkProof chooses ISP_1 for outbound session delivery, then the translated source address will belong to the ISP_1 IP address pool for the inbound response.

Internet traffic is optimized by the LinkProof through intelligent load balancing based on the current session and/or load per verified ISP connection. Additionally, network proximity is measured to determine the closest and fastest route. Network proximity is calculated in both router hops and round trip latency. This allows multi-homed sites to transmit information through a fast, healthy route.

LinkProof also uses proximity detection to perform inbound traffic management. For Internet users attempting to access a resource on the enterprise network (such as a Web server), the LinkProof uses DNS to assure the most optimal ISP connection. This feature allows the LinkProof to consistently use the best and quickest path to satisfy user requests for information.

The LinkProof continuously monitors the health of all routers in the farm, and periodically checks each router path and the health of user defined nodes beyond the router. This monitoring allows the LinkProof to continually send sessions through healthy routers on a healthy Internet path.
