Coriant, a global supplier of SDN-enabled transport networking solutions, announced the release of a new white paper, “The Emerging Mandate for More Flexible Mobile Infrastructure,” prepared by Heavy Reading, on behalf of Coriant and Brocade.
The white paper highlights results of a global survey of more than 80 mobile operators on the importance of Software Defined Networking (SDN) and Network Functions Virtualization (NFV) in mobile network transformation. The survey showed that more than 80 percent of respondents have a high interest in deploying SDN in the mobile network to optimize network operations.
"This survey revealed an emerging consensus among leading mobile network operators around best methods for designing, building, and operating mobile network infrastructure for the next five years," said Patrick Donegan, Chief Analyst, Heavy Reading. "Specifically, the survey results lead us to believe that distribution, virtualization, and programmability of networking features by leveraging SDN and NFV will be critical enablers of mobile network transformation."
Heavy Reading analysis of the responses from networking professionals employed by converged and pure play mobile operators throughout the world uncovered mounting evidence that SDN and NFV will play a critical role in meeting the growing requirements for flexibility in mobile network infrastructure. The survey results also highlight a growing trend toward distribution of data centers, with 44 percent of operator respondents viewing distribution as being central to their data center strategy over the next few years. The distribution of data centers drives increased demand for virtualized Evolved Packet Core (vEPC) and SDN-enabled programmability to support more stringent latency and reliability requirements at the mobile edge. In addition, the survey also revealed that nearly two thirds of respondents expect phase synchronization, a mandatory requirement for LTE-A features such as coordinated multipoint (CoMP) and enhanced inter-cell interference coordination (eICIC), to be deployed in their network within three years.
