Wi-Fi issues and DHCP concerns highlighted in Nyansa report

Wi-Fi issues dominate performance problems, according to Nyansa; Riverbed studies the effect of the Olympics on corporate networks; Array Networks releases a virtualized ADC.

Wi-Fi issues accounted for 64% of user problems on the corporate network, according to a study by network analytics company Nyansa Inc.

In addition to Wi-Fi issues, users most commonly reported problems with RADIUS authentication, Dynamic Host Configuration Protocol, domain name server and Address Resolution Protocol performance. RADIUS generated 13% of glitches, with the other three technologies accounting for 12%, 4% and 7% of problems, respectively.

Nyansa, based in Palo Alto, Calif., released its benchmark report after analyzing 76 billion client device issues collected by its Voyance network performance tracking tool, which launched in April.

"In a remarkably short period of time, we've been able to collect an unprecedented amount of business intelligence about how live enterprise networks are behaving and their actual impact on every user's experience as they journey across increasingly complicated computer networks," Anand Srinivas, co-founder and CTO of Nyansa, said in a statement.

Other findings from Nyansa's analysis indicated, among software-as-a-service applications, Dropbox and Skype consume some of the most bandwidth -- trailed by Box, Gmail and Office 365. In total, 83% of devices covered in the study were 5 GHz-capable, and Nyansa found the top-performing networks with the fewest Wi-Fi issues used the 802.11ac standard. Only 1% of enterprise networks were found to be using multiuser multiple input/multiple output. 

Riverbed study looks at Olympics' effect on network performance

More than eight out of 10 companies said they are closely monitoring how network and app performance is being affected by employees streaming coverage of the 2016 Summer Olympics, according to a global snapshot study conducted by Riverbed Technology.

"As athletes prepare for the games, IT organizations need to prepare for the significant increase in network traffic that will occur as a result of employees accessing and streaming online content and applications, and the related increase in volatility of that network demand," Mike Sargent, senior vice president and general manager at Riverbed, said in a statement.

Of particular concern was the potential strain on corporate Wi-Fi networks, Riverbed said. Almost 70% of respondents said they've experienced network performance issues specifically because employees were accessing a popular event during working hours. To that end, 24% of respondents said they'd limit employee access to Olympics content, while 46% said they'd probably limit content.

Array offers entry-level virtualized appliance

Array Networks Inc. beefed up its portfolio of application delivery controllers with an entry-level virtualized appliance equipped with load balancing, Secure Sockets Layer (SSL), VPN and web application firewall capabilities.

The AVX3600, available now, can run one large, two medium, four small or as many as eight entry-level appliances, according to Array. It's engineered for multi-tenancy deployment, and it can host multiple application and security tasks.

According to Array, the AVX3600 offers dedicated CPU, SSL and memory, and it provides the ability to mix and match virtual appliance sizes and functions.

"Service providers and enterprises are moving toward cloud and virtualization technologies, but are faced with challenges in maintaining performance and cost-efficiency for application delivery and security functions," Paul Andersen, director of marketing at Array, said in a statement. "With the AVX3600, these customers get the best of all worlds -- the agility and management efficiency of virtual appliances, the guaranteed performance of dedicated appliances and the ability to cost-effectively support a larger number of smaller customers or applications," he added.
