Look for capabilities that include historical and forecasted analysis on node and network-level performance and usage.With 5G comes new RAN architectures and more transport interfaces.
Ericsson Network Manager Drivers For 5GThese new interfaces have varying requirements for capacity, latency and advanced functionalities like network-based timing and synch distribution and traffic management (Ericsson Blog: Hubs, heat, and hops: market drivers for 5G Transport).In addition to these changes, there will also be an impact on the way communications service providers manage 5G transport networks.This approach works mainly due to the fact the RAN architecturedistributed RAN (DRAN)is relatively homogenous. The RAN organization is responsible for managing the RAN part of the network. They use software, tools and processes that work specifically for their domain. Same goes for the traditional IPOptical transport network organization. So much so, that the relationship between the RAN and traditional transport organizations are much like a customersupplier relationship. ![]() ![]() Then, the Transport team would validate their connection was uprunning. If no fault was found in either domain, it became complex and cumbersome to troubleshoot and isolate end-to-end network level problems. Recent market research from OMDIA Technology shows small cell connections are forecasted to grow significantly in the coming years, 26 percent CAGR though 2023. ![]() Simply put, the way we as an industry approached managing discrete domains in the past just wont scale efficiently and effectively for 5G. Since the transport network is the glue (theglue) binding all these disaggregated and virtual 5G network elements together, network management becomes a significant factor in successfully launching, operating and maintaining a 5G network. To deliver on the promise of 5G, transport network management tools and processes must evolve and keep pace with the 5G network as it evolves. There are three key characteristics to consider for a 5G-ready transport network management system. In this way, fault management (FM), configuration management (CM), performance management (PM) and other applications work together to present a unified, contextual view of the network. This is critical to reduce troubleshooting time and decide on remediation actions. The transport network management platform should be modular, and scalable enough to support high capacity transport networks. It should be capable of handling multi-layer connectivity and support a multi-vendor environment. With densification and virtualization coming with 5G, the tools and processes used to manage 4G mobile backhaul will struggle to manage the new fronthaul and mid-haul transport network segments. Analytics that can turn data into insights is important as complexity increases.
