Multi-dimensional Resource Aggregation in 5G Optical Fronthaul Networks
            draft-multi-dimensional-resource-aggregation-02

Abstract

   We propose a resource assignment scheme based on multi-dimensional
   resource aggregation in 5G optical fronthaul networks.  This new
   scheme can suit to the higher demand of flexible resource allocation
   of the fronthaul in the new 5G scenario.

1.  Introduction

   With the development of computer technology, the application of 5G
   technology has become more and more extensive.  For its ultra-high
   transmission rate and huge data capacity, 5G technology has made
   great achievements in our daily life and work.  The future 5G network
   will integrate artificial intelligence, SDN, NFV, and cloud computing
   technologies to adapt to more and more complex application scenarios.

   The 5G network architecture is totally different from the 4G network.
   The application of cloud technology has emerged in the 5G network
   architecture.  In the traditional C-RAN, all the base station
   computing resources are aggregated into the BBU pool, and distributed
   radio frequency signals are collected by RRH[1][2].  Parts of the 5G
   network are centralized into several clouds according to their
   separate functions which are controlled to form the "three clouds"
   architecture of the 5G network.  The access cloud supports multiple
   wireless access modes, including converged centralized and
   distributed.  It is able to be adaptable in various backhaul links
   and increase flexibility in the whole network.  The control cloud is
   used to achieve local and global session control and realize the
   mobility management and QOS.  It also builds an open interface for
   business-oriented network capabilities.  The transmit cloud improves
   the reliability and reduces the latency of the whole network.  It
   also achieves efficient transmission of massive traffic data flow
   under the control of the control cloud [3].  Moreover, compared with
   the 4G network architecture, the 5G architecture separates the base
   station processing unit, and reconstructs the BBU unit according to
   the real-time nature of the processing content into two functional
   entities which are CU and DU.  The CU is mainly responsible for the
