5 TRENDS FOR CIO’S AND NETWORK MANAGERS TO WATCH IN ENTERPRISE WAN

This week Telehouse Europe announced the launch of Telehouse Enhanced Connect – a revolutionary new service delivering super-efficient connectivity from the remotest places on the planet.

Complimenting your existing network, Telehouse Enhanced Connect uniquely optimises performance continuously from the first mile to the end point delivering greater data stability and a more consistent user experience.

Here are the top 5 most significant trends that will impact CIOs, IT Directors, Network Architects, and Network Managers, as the global enterprise WAN evolves.

1. Global enterprise traffic grew at a mean rate of 236%, in 2014. 
Enterprise traffic in EMEA grew the fastest at a mean rate of about 399%; traffic in APAC grew 201%, while traffic in North America grew 190%.

2. First- and last-mile links are improving globally. 
EMEA locations have the highest percentage of high-speed access site last-mile WAN links. However, owing to the improved quality of last-mile links globally, EMEA now lags behind the global average for very high-speed WAN links. North American access sites, while lagging behind EMEA slightly in regards to high-speed last-mile links, actually have a higher percentage of very high speed links. Compared to last year, APAC has seen a substantial growth in very-high-speed WAN links, even surpassing EMEA and the global average. A full 21% of APAC sites have links >20 Mbps, up from 14% last year. Another thing to note in APAC is that many sites (about 33%) still have low-speed connections of less than 10 Mbps. This indicates a huge amount of disparity among enterprises with offices in APAC.

3. Enterprises typically see less than 0.25% packet loss over the last-mile link, even in emerging markets like China and India. 
The global median packet loss is a mere 0.04%. As one might expect, the percentage of sites experiencing a relatively large amount of bad minutes in regions like North America and EMEA is low. However, over longer distances, the public Internet more unpredictable, since network problems in the middle mile tend to reduce application performance.

4. HTTP traffic continues to dominate – pointing towards heavy cloud adoption rates. 
HTTP traffic over the WAN has proved more popular with Enterprises; however HTTPS is not far behind. This is followed by CIFS traffic over the WAN; of which the largest proportion are MS remote desktop users; followed by SMTP, SSH, FTP, and Citrix users.

​5. Among the many techniques leveraged in WAN Optimisation solutions, data deduplication, compression, and caching account for a sizeable reduction in data flowing across a WAN pipe. 
Using these technologies, WAN Optimisation vendors are able to provide not just bandwidth savings, but also the ability to accelerate application performance. Despite the talk around more application data being encrypted or pre-compressed, many protocols, including CIFS, HTTP, IMAP, and MSSQL, can still see bandwidth usage savings of 50% or more. With the right optimisation technologies in place, data reduction can help enterprises keep up with skyrocketing bandwidth demands, at least in the short term. In the longer term, more advanced, unified approaches will be needed.
 
Telehouse Enhanced Connect utilises Aryaka’s network optimisation technology. Aryaka selected Telehouse Europe as its preferred data centre partner because of its connectivity with major cloud providers and enterprises and the sheer volume of Internet traffic that goes through its data centres.
