Integrated Transport Systems
With the high increase in capacity of the access network, the current network bottleneck is for the first time not in the RAN or in the compute capabilities of the core. Instead, the bottleneck is in the transport. Especially with the adoption of ultra-low delay communication and of long distance, global connected networks, there is a need to converge at control layer between the RAN, core and transport.
The following types of transport require additional control layer convergence:
- ultra-reliable, low delay backhaul in local networks – any minor communication effect will be immediately impacting the URLLC type of service
- Scheduled low resource backhauls – with having a very large capacity in the access network, the devices could immediately congest any backhaul. A coordinated end-to-end resource scheduling would be needed in order to assure the appropriate communication prioritization
- Selection the appropriate backhaul – mobile and nomadic edge networks could potentially use multiple types of transport from different providers, subsequently or in parallel. An appropriate selection is needed.
- Opportunistic backhaul usage – for long distance use cases it is important to understand the momentary available resources and to use these resources when appropriate
- Deterministic backhaul – assuring that data packets are arriving within a specific time interval, adapted to different reliable and unreliable backhauls, has a very large use case potential
