Highlights / Steps to implement
Higher peak date rate
To offer high capacity services to the final user, high data rate in the back and front haul (X-haul) has to follow. Differently from before the capacity growth expected to enable 5G is of an order of magnitude
Is a requirement that is getting more and more stringent with the releases of new access technologies. The shorter the latency requirements is (sub-milliseconds) and the most performing the transport network needs to be, to carry traffic across the network. Beside architectural expedients to optimize the topology, transporting data at lower layers is the real improvement. Hence by-passing buffers, queue and egress shaping algorithms.
The deployment of multi-rat technology, Het-Net and different architectural models of backhauling and front hauling will overlap. The different services need to coexist and perform at their best to achieve the expected results.
Convergent Optical Layer
When the capacity grows and latency needs become stringent, the need to transport capacity at the lowest level possible becomes imperative. WDM technology offers the capability to do just that.
Wired and Wireless
Convergence of fiber based and wireless transport becomes a stronger asset than ever for mobile operators who find themselves in the position of accessing a larger tool-box of solutions to homogeneously address the mobile transport network with multi-gigabit transport options regardless of the underlying physical media.
SDN centric solution
The current incumbent-captive solutions are a stopper to the "best of breed" approach that mobile operators want to adopt in order to maintain a flexible and fast evolving network. The introduction of SDN centric solution is a way to lower to a minimum the barriers of new technology introduction.
