2 Page Introduction This document outlines the differences between Radware multi-homing products: 1. : a full-featured, high-performing link manager designed for bandwidthintensive and performance-demanding networks. Usually, these networks are found at the headquarters and regional offices of large enterprises. manages the operation of all Internet links across multi-homed networks, optimizing content delivery for reliable, cost-effective and secure connectivity. Depending on the traffic throughput requirements and IP performance needs of the network, can be deployed any one of Radware s three Switch platforms. From large regional offices through leading national carriers, the Switch platforms provide an all-encompassing multi-homing solution. 2. EL: a limited throughput link manager targeted at regional offices. Sold only on the Switch I platform, EL has two major limitations. First, the bandwidth is limited to 10 MB with the North American (NA) license, and 5 MB with the Rest of the World (ROW) license. Second, there is no ability to purchase a license. However, EL is upgradeable to a full, unlimited bandwidth with a change of license. Customers can then choose to add a license. 3. : a small desktop box with feature set designed to meet the needs of Remote Offices and Offices (ROBO). provides ROBOs with increased connectivity flexibility, leading to sharply reduced connectivity costs. Offices are also able, for the first time, to maintain accelerated and uninterrupted connectivity to the central office by intelligently routing Internet traffic, including VPN sessions, across multiple Internet links. In this way, organizations benefit from increased employee productivity while saving connectivity costs. 4. UpLink - is a small desktop box that enables small and medium enterprises (SME) to manage two independent ISP links simultaneously, enabling businesses to deploy more cost-effective connectivity solutions. By connecting UpLink on the edge of their local network, enterprises benefit both from the ability to multi-home their network, thus guaranteeing 24/7 Internet connectivity while significantly reducing connectivity costs.. The table below compares the different multi-homing product line and their respective target markets and key differences.
