Mobile network applications

Mobile networks have been posed with various challenges over the years, which includes network flexibility and management. The management of the network has been a difficult task because of the diverse customer segments it supports and the Operations Support Systems (OSS) and billing support systems tools used for billing the subscriber.

SDN promises a significant boost in network management and flexibility because of the support for more granular traffic monitoring and dynamic bandwidth allocation. Network congestion, a critical challenge posed to a service provider, is addressed by SDN because the controller can optimize the various northbound apps in accordance to the network traffic in real time.

A striking advantage of the SDN implementation is multitenancy. It allows multiple mobile operators to utilize the same physical infrastructure. With SDN, this will be intelligently supported because the OpenFlow controller will support the application of granular policies to their traffic by multiple mobile operators.
