Radware Cuts WAN Costs
Providing high availability for remote branch offices and lowering WAN costs have often been at odds, but Radware Ltd. says it has found a way to do both.Providing high availability for remote branch offices and lowering WAN costs have often been at odds, but Radware Ltd. says it has found a way to do both. Radware, best known as a maker of high-speed Layer 4 to Layer 7 switches, this week is rolling out its LinkProof Branch device. The tool lets enterprises use lower-speed links from multiple service providers at remote branch offices to replace more costly T-1 lines while ensuring that bandwidth is available for critical business applications, officials said.
Because the device automatically fails over to a backup link and performs load balancing across the links, "you can replace an existing T-1 with two business-rate DSL [digital subscriber line] links. If you only look at connectivity costs, you will save over $8,000 a year for a branch office," said CEO Roy Zisapel, in Tel Aviv, Israel, who based the savings on AT&T Corp. pricing. "With the broadband connectivity options enterprises have today, they can save a lot of money and guarantee the availability they need," Zisapel said. If a site requires bandwidth above T-1 rates, that enterprise could avoid the cost of a second T-1 line or fractional T-3 rates and save more than $12,000 annually for a single branch, he said.
