Heavy Reading Survey Indicates Significant Growth Trend for 100G Networks and Virtual Appliances

A custom study conducted by independent research firm Heavy Reading for Napatech reveals that by 2018, access, metro and core transport networks will have reached the tipping point from a service delivery perspective. As the need to support high-bandwidth services continues to grow, the requirement for greater throughput is driving a steep rise in the penetration of 100G networks. Heavy Reading attributes this sharp growth spike to the preliminary impact of early 5G network upgrades to support the high capacity this new technology will consume.

Over 135 qualified service provider and vendor respondents from a global list of communications service providers (CSP) and network equipment providers (NEP) anonymously participated in the survey. Key findings include:

  • Network appliances are undergoing a fundamental transition: Two drivers are responsible for this transition: increased transport network throughput and the impact of virtualization. The report reveals that the traditional hardware appliance market has reached maturity and will be extended with 100G solutions and then, over time, replaced with virtualized appliances.
  • 100G transport networks to increase dramatically: Increases in data network throughput are happening at all levels due to the deployment of 100G. The survey forecasts that the 100G transport network penetration will grow significantly by the end of 2018:
    • From 22 to 75 percent increase in core transport networks
    • From 14 percent to 71 percent penetration in metro networks
    • Nine percent penetration to 58 percent growth in access networks
  • Profound impact of SDN/NFV expected: The impact of SDN and NFV on network appliances will be profound but positive overall. With virtualized network appliance growth on the rise, both NEPs and CSPs see a continued need for network appliances in a 100G virtualized world.

Henrik Brill Jensen, CEO, Napatech, said:
"As data growth continues to accelerate, increases in data network throughput are occurring at all levels due to the deployment of 100G. We are committed to delivering solutions that assist our customers in analyzing data at maximum throughput without compromise. This report is a strong indicator that our best-of-breed accelerators are poised to provide our customers with the tools they need to meet the demands of today's high-speed, physical and virtual network environments."

Jim Hodges, senior analyst, Heavy Reading, said:
"The study identifies that both CSPs and NEPs not only understand the value of traditional hardware appliances, they also recognize the strong value proposition of virtualized network and security appliances to help them optimize the performance of NFV-enabled networks."
