When deploying 5G mobile networks on top of existing or newly built
optical transport infrastructure, network operators and telecom
service providers are interested in implementing open solutions that
enable hardware platforms (HPs) and software/operating systems
(software/OS) from different vendors to be deployed on the same
transport network. This interest is also stimulated by introduction of
new, cloud-based, technologies on 5G networks with extensive use of
data centers. For open optical transport solutions, vertical (separation
of APs and software/OS) and horizontal (functional decomposition of
network nodes) disaggregation options are considered. The series of
papers presents fully or partially disaggregated solutions (part 1), gives
an overview of works on standardization of solutions (part 2) for open
optical transport networks.
