Software-defined network (SDN) and large-scale network virtualisation both playing their part.
Software-defined network (SDN) and large-scale network virtualisation expected to drive the telecom networks with an enhanced software-centric and programmable telecom infrastructure and services ecosystem, according to a new report from IDC.
Both the technologies are expected to have a sustained impact on current communication service providers (CSPs) and their business approaches, the report added.
IDC Telecom Services and Network Infrastructure research manager Nav Chander said that the rapid global growth of data and video traffic across all networks, the rise in use of public and private cloud services, and the desire from consumers and enterprises for enhanced service and application delivery have been driving the telecom markets toward an inevitable era of network virtualisation.
"SDN and large-scale network virtualisation will become a game shifter, providing important building blocks for delivering future enterprise and hybrid, private, and public cloud services," Chander said.
Large data centres incorporated with CSP networking will be the first combat zone for SDN, while networking data centres deployed with SDN-based solutions will be driven by the needs for hyperscale networked data centres created by specialist cloud providers.
In addition, the ability of CSPs' to embrace new disruptive software platforms will pave the way for multivendor network virtualisation.
According to the report, major CSPs have collaborated to set up a new Network Functions Virtualization (NFV) group to identify a set of virtualised network functional requirements.
The collaboration is aimed at trimming down the specialised and fragmented proprietary hardware-based network appliances or network elements and the necessities for a physical install per appliance, per site.
