    Remote Applications Drive Bandwidth Demand

    Multiprotocol Label Switching is not adequate to meet the demands created by remote applications, which are driving the requirements for greater bandwidth.

    Increase in WAN Traffic Across Verticals

    Software and internet verticals combined show the greatest increase between 2015 and 2016, growing from 307% to 526%. Manufacturing rose from 296% to 441%, and Financial Services jumped from 111% to 371%.

    HTTP and HTTPS Dominate

    Nearly 50% of today's enterprise traffic is a combination of HTTP and HTTPS, as applications continue to transition from monolithic on-premises models to web-based consumption and delivery models.

    Bandwidth at Non-HQ Sites

    Globally, only 12% of respondents have links with bandwidths that are less than 10 Mbps, and 25% have more than 100 Mbps links. In developing countries, access-site bandwidth is 2 Mbps.

    Response Times Vary With Distance

    TCP application responses times have a variation of 200%, depending on the distance between sites. As the distance increases, the problem gets worse.

    Infrastructure Affects Response Times

    Inconsistency in application response times depends on network infrastructure. In the Middle East and parts of Asia, conductivity makes matters worse, resulting in response times as high as 153% and an average application response time of one second.

    ISP Handoff Gets Worse

    Internet bandwidths and quality are increasing at the WAN edge and over short distances. But the handoff between ISPs over the internet or IP-VPN is getting worse, affecting the performance of business-critical applications.
 

WAN managers need flexible network services due to the growing demand for higher bandwidth and predictable connectivity to applications that are remote, according to a new study, "State of the WAN Report," conducted SD WAN-supplier Aryaka. Traditional Multiprotocol Label Switching (MPLS) no longer satisfies that need in a cost-effective and scalable way because of the high price of hardware and the demands it creates on time, deployment and maintenance. Furthermore, MPLS is a point-to-point technology that does not meet the challenge of connecting to public cloud data centers. "Understanding the state of the WAN—and the impacts that global network traffic has on business strategy—gives IT leaders the ability to partner with their C-suite to enhance business execution," said Shawn Farshchi, president and CEO of Aryaka. Nearly half of all global enterprise traffic now encompasses cloud and software-as-a-service technologies, but legacy technologies like MPLS fail to address this trend, he said. The report provides a detailed look into the current state of WAN infrastructure and its impact on global business, based on data aggregated from 5,000 sites in 63 countries.
