Dear Authors of the GCI,

This is so amaizing report.

I have a question.

Since when the forecast data start?

Thank you very much in advance and best regards.

Hello Daisuke Oka-san

Thanks for your interest in the Cisco Global Cloud Index (GCI). The Cisco GCI incorporates a bottom-up and top-down approach to derive global and regional results. The methodology begins with the server shipments to different types of data centers (traditional, private cloud, and public cloud), calculating the installed base of workloads and compute instances. Then it applies the volume of bytes per workload and compute instance per month to obtain the traffic for current and future years within the forecast period. We have used a variety of data sources, such as Gartner, IDC, Synergy, Juniper Research, and Ookla, for GCI analysis. For traffic modeling and verification of data center traffic types and volumes, network data from various enterprise and Internet data centers was reviewed. Our GCI data center traffic forecast is based on three key destination areas:

Data center to user: Traffic that flows from the data center to end users through the Internet or IP WAN
Data center to data center: Traffic that flows from data center to data center
Within data center: Traffic that remains within the data center, excludes traffic within the rack

For 2016, the data center to user traffic is based on actual data. With data center to data center and within data center traffic, the traffic figures are modeled based on partial actual data and the methodology stated above. The GCI effort commenced eight years ago, but unfortunately we don’t any historical traffic or other related data that can be shared.

We appreciate your reference to the traffic by geography forecast figures and any other VNI data, per the below simple guidelines available within the GCI Q&A:

May I or my organization or company use or publish Cisco GCI forecast data?
Yes. Cisco welcomes and encourages press, analysts, service providers, and other interested industry parties (business, regulatory, or academic) to use or publish the data. We do require that proper Cisco attribution be given for any and all Cisco GCI data that is published or shared in private or public, print and electronic forms (for example, source: Cisco Global Cloud Index [or Cisco GCI], 2016–2021). No further signatures or consents are required to reference our publicly available white papers and reports. We are always interested in the context in which our data is used and would appreciate it if parties that use our content would share copies of their completed work containing Cisco GCI insertions.

Hope this helps.

Thanks and best regards

Would it be possible to get the yearly figures for global data center traffic between 2016-2021? Thanks!
