IHS is out with its 2015 report which breaks down how the top six revenue-producing vendors in enterprise networking and communication equipment are faring.

The “Scorecard” dubs Brocade, Cisco, HP and Huawei as the four leaders – for various reasons – saying that they are “stable and well-known companies, have worked to diversity their offerings, and are generally well-regarded by enterprise buyers.”

Also evaluated in the scorecard – but not mentioned among the four leaders – are Avaya, which IHS applauds for its longstanding position in the enterprise market, with more than 20 years of selling telephony and managed services; and Juniper Networks, which targets large, high-value enterprises with complex networking requirements. Juniper, IHS also notes, has mature routing, switching and security products and services.

“Networking and communication technologies are critical elements for the operation of any enterprise, and the companies profiled in our scorecard are capable of addressing a wide range of enterprise needs,” said Matthias Machowinski, research director for enterprise networks and video at IHS.  

To determine its market leaders, IHS says it uses concrete data and metrics such as market share and momentum; financials; “next-generation intensity”; and buyer feedback on product reliability, service/support and technology innovation.
