You Can’t Have Consistent Unified Communications (UC) Without A Reliable Network

The use of unified communications (UC) applications is surging at the enterprise level. According to Infonetics, for instance, the UC market — along with VoIP — will reach $88 billion by 2018.

What’s driving the growth of UC in enterprises? As explained in our recent webinar, businesses are turning to UC solutions to increase end user productivity and enhance business processes, which, according to Gartner*, are the goals of unified communications. Video, voice, unified messaging, web conferencing, and real-time collaboration applications are among the common UC tools used in the enterprise.

Although UC deployment is becoming increasingly ubiquitous, a number of companies are still struggling to achieve a consistent and reliable UC experience. In many cases, it’s because the strain that real-time communications and collaboration solutions can place on a wide area network (WAN) is often underestimated. To be reliable, UC requires quality of service and adequate bandwidth. A 2014 InformationWeek report** shows that demand for bandwidth—driven by UC, enterprise video and the cloud applications—is increasing by 30 percent year-over-year.

Kangwarn Chinthammit, CCIE, noted during the webinar: “IT administrators are very concerned about the issues like Quality of Service (QoS), a lack of bandwidth and configuration complexities.”

Further, other network impairments like jitter, packet loss and latency can arise which can create disturbances and negatively affect UC experiences for end users.

So, what’s the answer to improved UC experiences? A cloud-driven, software defined WAN (SD-WAN) solution that provides scalable amounts of bandwidth for businesses by enabling transport over less expensive Internet links while assuring enterprise-grade performance. Click here to access the webinar and learn more about how your business can benefit from a Cloud-delivered SD-WAN.

The top three ways an SD-WAN framework improves UC quality and enhances user productivity and satisfaction:

Traditional WAN SD-WAN
Consistent Network Performance
DSCP-based QoS. Assume link condition is good Application-aware QoS & performance-aware
path selection and remediation
Growing Bandwidth Demand
Private WAN bandwidth upgrade Add bandwidth with Internet links while
assuring performance
Hybrid Deployment of UC Applications
Inflexible static WAN & complex routing configuration Architecture supports both on-premise & cloud deployment
