Technology market research firm Infonetics Research, now part of IHS Inc. (NYSE: IHS), today reported that the Diameter signaling control market will grow threefold between 2014 and 2018, to $1.3 billion.

Infonetics’ Diameter Signaling Control report tracks Diameter signaling controllers, which handle and secure the exponentially increasing Diameter signaling traffic on service provider networks triggered by mobile IP data and voice services. 

“Developed as the next-generation signaling protocol, Diameter has begun to permeate networks, driven by increasing LTE usage and the emergence of VoLTE (voice over LTE). As a result, the Diameter market spiked 81 percent in 2014 from the previous year,” said Diane Myers, principal analyst for VoIP, UC, and IMS at Infonetics Research.

Myers added: “The Diameter vendor landscape is beginning to shake out, and it’s a tight race at the top between Huawei, F5and Oracle. We see a strengthening of Ericsson and a push from Alcatel-Lucent, Sonus and now Mavenir with its acquisition of Ulticom. The consolidation continues, and we expect even more in 2015.” 


  • Globally, the Diameter signaling control market totaled $381 million in 2014, an increase of 81 percent over 2013
  • The top use case for Diameter signaling control in 2014 was once again centralized routing, but roaming via DEA (Diameter Edge Agent) was right behind
  • North America accounted for over a third of Diameter signaling controller revenue in 2014, followed by EMEA and Asia PacificInfonetics looks for Diameter signaling controllers to be implemented as VNFs (virtual network functions) beginning in 2015, with North American operators and a few Europeanmobile operators leading the way
    • Growth in the regions is predominantly tied to rising LTE subscribers, however in EMEA, where there are many more operators, the need for signaling controllers for roaming is having an impact
  • Infonetics looks for Diameter signaling controllers to be implemented as VNFs (virtual network functions) beginning in 2015, with North American operators and a few European mobile operators leading the way 


Infonetics’ annual diameter signaling control report provides worldwide and regional market size and forecasts through 2019 of manufacturer revenue and transactions/second licenses for Diameter signaling controllers, which provide centralized routing, traffic management and load-balancing in IMS and mobile broadband networks. The report includes market analysis, trends and a Diameter deployment tracker. Companies tracked: Alcatel-Lucent, BroadForward, Dialogic, Diametriq (Intellinet), Ericsson, F5 Networks, Huawei, Openet, Oracle, Sonus Networks (PT), Ulticom (Mavenir) and others.
