VeloCloud: Variable Performance for Broadband WAN Connections

Businesses relying on broadband lines (DSL, cable, LTE, Ethernet or fiber) continue to experience variable and insufficient performance one-quarter of the time, according to data compiled by VeloCloud Networks.

Specifically, the VeloCloud Internet Quality Report for enterprise applications performance measured packet loss and jitter/latency during work hours over Internet WAN connections. Data was gathered by continuous monitoring of VeloCloud’s cloud network service. These 2H2014 results of 6 million link statistics cover more than 60 locations and 50 ISPs.

“The survey confirms that unpredictable Internet performance can’t be solved by switching Internet service providers (ISPs), changing the type of service (DSL, cable, LTE, Ethernet or fiber) or throwing any amount of bandwidth at the problem,” said Sanjay Uppal, CEO and co-founder of VeloCloud. “But it also shows that by fundamentally transforming how these inexpensive broadband links are utilized, enterprises can use the Internet as their WAN to augment their existing private lines, at a fraction of the cost.”

Key findings of the VeloCloud Internet Quality Report include:

  • During business hours (defined as 8 a.m. to 6 p.m., local time), Internet links could not deliver enterprise-quality real-time traffic 25% of the time, on average.
  • Poor performance varied by city from as low as 1% to over 50%. This magnitude of variation was found even within an ISP’s service in the same city over time.
  • There was no improvement in performance even as available bandwidth increased to 200Mbps and more.
  • An overlay cloud-delivered SD-WAN service, featuring dynamic multipath optimization, was able to deliver enterprise-quality application performance 99.3% of the time.
  • Unreliable Internet Links Equals Money Lost
  • Enterprises want to optimize both real-time application performance and costs across their WANs. As the network demands of these real-time applications have increased, so has the number of applications delivered from the cloud. These changes are driving enterprises to look to the Internet for a more cost-effective way to connect directly to cloud applications. However, broadband Internet links to date have not been able to deliver the quality needed to run enterprise applications.

The VeloCloud report includes a Quality Score that rates the ability of Internet connections to support application performance. This scoring is consistent with industry standards, such as mean opinion scores (MOS) for VOIP, and calibrated with third-party tools. The real-world data has been anonymized and aggregated to ensure customer privacy.

  • In July 2014, VeloCloud Networks, a start-up based in Mountain View , California, launched its subscription-based, virtualized WAN service for enterprises that aggregates multiple access lines (cable modem, DSL, LTE) into a single secure connection that is defined and controlled in the cloud. The VeloCloud service uses an Intel-based customer premise device at a branch office to communicate with a VeloCloud gateway in the cloud. The service analyzes network performance and application traffic to determine the best path and dynamically steer traffic to corporate data center or cloud services.
    Compared to MPLS VPNs, VeloCloud said its services offers a significant cost savings because it uses available Internet access lines while delivering enterprise-grade reliability and performance. Advanced network services, such as application-aware firewalls, can be virtualized on the CPE or delivered in the network.  VeloCloud will charge a flat fee per month per location served. The subscription service comprises a Cloud Orchestrator, distributed Cloud Services Gateways and a Cloud Services Edge per branch.
