[Survey]: Huawei, Ericsson and Alcatel-Lucent are the Top IMS Vendors

  

Diane Myers [pictured], research director for VoIP, UC and IMS, IHS (Infonetics Research): "conducted in-depth interviews with global service providers that have IP multimedia subsystem (IMS) core equipment in their networks or will by the end of 2017 and discovered that only 8 percent are running IMS network elements in a network functions virtualization (NFV) environment today .. more are on the path by starting to utilize software running on commercial off-the-shelf hardware as a stepping stone to full NFV. One of the biggest drivers for NFV is the ability to scale services up and down quickly and introduce new network services more efficiently and in a timely manner, which makes IMS a good early fit for NFV".

"80 percent of service provider respondents indicated that parts of their IMS elements will be running in an NFV environment by 2017, which IHS believes is somewhat optimistic. In an open-ended question asking respondents who they consider to be the top three IMS infrastructure vendors, operators most often named Huawei, Ericsson and Alcatel-Lucent"
