Multi-Segment Optimization: How Cato Cloud Modernizes WAN Optimization for Today’s SD-WAN

April 30, 2018

As our networks have evolved so to have the challenges of optimizing application performance. Our new eBook,  “Cato Networks Optimized WAN and Cloud Connectivity”, analyzes those challenges and explains Cato’s unique approach to overcoming the performance limitations in today’s cloud- and mobile-centric organizations.

WAN optimization was designed to overcome the limitations of MPLS-based networks. Bandwidth was expensive, which made every bit of performance essential (and, yes, pun intended). WAN optimization compensated for the latency and limited bandwidth of MPLS. Appliances deployed in branch offices and the private datacenters housing corporate applications addressed those factor, improving network throughput. And with MPLS’s high-costs, cost justifying WAN optimization was often relatively straightforward.  

But shifts in how we work and cloud adoption have changed that optimization-equation significantly. For one, embracing SD-WAN and the Internet means we’ve eliminated the high-costs and limited bandwidth of MPLS. Saving Internet bandwidth is simply less of a priority today than it was 10 years ago. At the same time, minimizing the packet loss and the latency become far more important as applications are subject to the unpredictability of Internet routing.

And while IT had the freedom to improve MPLS performance with physical appliances that’s often not the case with today’s business. Cloud adoption means locating appliances within the datacenter may be difficult if not impossible and, regardless, users often work remotely, beyond the reach of WAN opt devices.

Cato’s unique multi-segment optimization addresses these challenges, bringing global coverage and MPLS-like latency at a fraction of the cost. “During our testing, we found latency from Cambridge to Montreal to be 45 percent less with Cato Cloud than with the public Internet, making Cato performance comparable to MPLS,” says Stuart Gall, Infrastructure Architect in the Network and Systems group at Paysafe, a leading global provider of end-to-end payment solutions (see figure).

“We were getting 2 Mbits/s of throughput on our SSL VPNs from North America to Israel,” says Oren Kisler, Director of IT Operations at Stratoscale, a provider of cloud-building blocks for modernizing enterprise on-premise environments. “With Cato, we saw throughput jump more than eight-fold, reaching 17 Mbits/s.”

Cato’s network optimizations improved Stratoscale’s data throughput by more than 8x.

The Cato Cloud bring a range of optimizations to meet the challenges for improving performance across the entire enterprise — locations, mobile users, and cloud resources. To learn more, download the ebook here.
