- In 2015, Current Analysis surveyed 100 decision makers at network operators regarding challenges facing network deployments, what they need most from their vendors, and which suppliers they view most favorably.
- Although a key focus of vendor messaging in 2015 was helping operators to operationalize SDN/NFV, operators are facing more fundamental questions standing in the way of their decision to fully embrace network virtualization: uncertain ROI.
- When asked what one thing operators feel the SDN/NFV supplier community is not adequately addressing, VNF performance dominated the responses. A word cloud below summarizes the key responses, with the size of each word corresponding to the frequency in which they appeared in the response results.
- Cisco and Huawei have topped SDN/NFV vendor perception results for the past several years. However, IT-oriented suppliers – namely HP and IBM – made up considerable ground in 2015, now ranking closely behind Cisco and Huawei as top perceived SDN/NFV suppliers.
- Ericsson also made a considerable jump in perception to round out the ‘Top 5’ in terms of best perceived vendors in the survey.
