Transforming transport networks
Tighter integration between radio, transport networks, and cloud infrastructure is needed to deliver the required level of flexibility. This must be carried out with a backdrop of small-cell deployment, convergence of access and backhaul, as well as the migration of legacy equipment and technologies
Increasing flexibility, reducing complexity
Services such as mobile broadband and media distribution will continue to evolve in line with our growing global dependence on connectivity. Subsequently, networks will experience huge increases in traffic and will need to service an ever-expanding number of connected devices – both massive and mission-critical machine type communication. The latter sets stringent requirements for performance characteristics, including reliability and latency.
Key to network transport architecture is:
Network transport functions
- Virtualization and centralization will make transport more automated and simplified transport will help cater for network slice-specific isolation and inter-slice prioritization requirements
- Transport control contains analytics, policy, functions and specific northbound APIs for service orchestration and level agreement reporting. Collection, presentation and correlation of various transport service level parameters on a per-service basis is one of the key capabilities
Meeting diversified demands
Adding new value
As the pillars of SDN, the ability to access network resources, functionality, and the management of services on-the-fly through programmatic APIs can reduce network complexity, as well as increase flexibility.
SDN can also provide service velocity as a means to integrate transport, radio, and cloud domains. This approach enables control to be centralized for service functions, and distributed for transport.
