According to latest reports from leading Trasnport Infrastructure vendors Ericsson and NEC . it is very vital to build Next Era Transport for 5G that can serve for MPLS and SRV6 end to end . When we think of future business cases like End to End Network Slicing it will become for important .
Transport for Open/C-RAN
As 5G will deploy in different scnerios and Cloud will be long term most lucrative one so transport must align with it by offering Packet and Ethernet based transport end to end from device to core preferably using e-cpri models that has significant low latency
Outdoor Dense Urban solutions
In Outdoor in city centers laying NG Fiber may not be feasible solution so offering connectivity using PON and MW is needed that is why it is important to not just lock with Fiber solutions
Automation of Transport
Just like others domains like RAN , Core , Edge the transport also need to be Orchestrated and must be optimized over time using ML and AI . the key for this is build a transport that can automate using T-SDN like ACTL workflows or Open ROADM and that can help collect all data that can be optimized with AI .Cool stuff
Future DC architectures
Transport should be flexible not only to offer transport based on 3GPP service model but based on DC architectures like solutions for Clos architecture , DIs-aggregated scnerios etc
Just like with other solutions in 5G the transport should be distributed like support for Hub /Be-spoke rather than full mesh for both reliability , performance and scale .
Security nevertheless is of paramount importance specially as we will open transport for 3rd party and whole sale connectivity although this domain is well addressed in Orchestration and End to End Slicing however as famous adage we must be leave the software boundary un attended .
