LinkProof Overview

LinkProof is an intelligent application switch that manages all links across multihomed networks, enabling full link availability, highest link performance, and complete link security for uninterrupted user access to web-enabled applications and cost effective connectivity at main offices and data centers.

LinkProof eliminates link bottlenecks and failures from enterprise multihomed networks, for fault- tolerant connectivity and continuous user access to IP applications, web-enabled databases, online services, corporate Web sites, and e-commerce. By intelligently routing traffic and moderating bandwidth levels across all enterprise links, LinkProof maximizes link utilization, driving application performance, economically scaling link capacities and controlling connectivity service costs. Securing all enterprise entry points and cleansing all link traffic, LinkProof delivers Denial of Service protection and intrusion prevention to protect distributed applications, resources, and users.

LinkProof performs load balancing of the outgoing and incoming traffic through the access routers and via the firewall. During this process, LinkProof is responsible for the following:

Forwarding the traffic to a server (router or firewall) that can provide the required service.

Selecting the most available server from the servers that provide each required service.

Ensuring that all the packets of a single request for service are forwarded to the same server.

LinkProof is installed in the path of a user community to the Internet. LinkProof must be defined as the default gateway for both inbound and outbound traffic.

LinkProof can be installed into a network as a bridge or as a router.

When installed as a router, LinkProof supports the following protocols:

Routing Information Protocol (RIP)

Routing Information Protocol 2 (RIP2)

Open Shortest Path First (OSPF)

Virtual Router Redundancy Protocol (VRRP)
