Network slicing is a powerful paradigm for network operators to support use cases with widely diverse requirements atop common infrastructure. As 5G standards are completed, and commercial solutions mature, need start thinking about how integrate capabilities in their assets, so that customer-facing can be made available portfolio. This integration is, however, not an easy task, due the heterogeneity of assets typically exist carrier networks. In this regard, networks may consist number domains, each different technological pace, built out products from multiple vendors, including legacy devices functions. These multi-technology, multi-vendor brownfield features constitute challenge operator, which required deploy operate slices across all these domains order satisfy end-to-end nature services hosted by slices. context, only realistic option introduce progressively, following phased approach roll-out. The purpose paper precisely help designing kind plan, means technology radar. radar identifies set enabling on individual classifies into four rings, corresponding timeline: (i) as-is ring, covering today's solutions; (ii) short term; (iii) test considering medium-term (iv) explore expected long run. classification done based technical availability solutions, together foreseen market demands. value lies its ability provide complete view landscape one single snapshot, linking information decision making go-to-market strategies.
