With the evolution of mobile network architectures throughout the generations, physical locations of their various components, as well as functionality provided by them, were evolving as well. As time went on mobile networks turned from monolithic, closed down systems running on dedicated hardware into more open, distributed and software defined systems the likes of which we can observe in today's 4G and 5G networks. This evolution hasn’t foregone the RAN segment of the network, so today we can see various movements focused on standardisation of the RAN network, most noteworthy of which is the O-RAN Alliance. This movement, and the organisation behind it, have been founded by the leading global telecom operators with the goal of creating a set of standards defining the RAN network as a set of interoperable components communicating over standardised interfaces. This in turn gives operators the ability to build and integrate their own networks using off the shelf components procured from vendors of their choice. The logic powering an O-RAN network is provided by two components, that being Near-RT RIC and Non-RT RIC, which are tasked with overseeing the network operations through their internal closed control loops which have execution periods in the range of a few milliseconds for Near-RT RIC and over a second for the Non-RT RIC. Since all the functions of an O-RAN network are intended to be software based, they can be executed on COTS servers provided by hyperscalers, located in distributed datacenters and connected over the public Internet. Therein lies a problem, because historically, RAN networks have been closed system connected using a dedicated fibre optic network infrastructure and as such were not directly connected to the Internet. To allow for the Internet to serve as a transport network for the RAN, a new eCPRI transport protocol had to be implemented, one which could be carried over packed based networks such as Ethernet or UDP/IP. All the aforementioned improvements have the end goal of lowering the CAPEX and OPEX costs for telecom operators as well as providing for a more competitive marketplace driving further technological advancements in this space.
