Open Compute Carrier-grade Edge Reference Architecture (OCCERA) Application for MEC
Open Compute Carrier-grade Edge Reference Architecture (OCCERA) Platform for Multi-access Edge Computing
To provide the required deployment flexibility and high performance for 5G mobile edge computing, ADLINK provides Open Compute Carrier-grade Edge Reference Architecture (OCCERA) platforms for Centralized/Cloud Radio Access Network (C-RAN) deployment that offer high-density computing resources, that can endure the extreme conditions of harsh outdoor environments.
C-RAN
C-RAN architecture consists of three parts: a distributed wireless network comprised of a remote radio Unit (RRU) and antennas, a high-bandwidth and low-latency optical transport network, and a centralized baseband unit (BBU) pool consisting of general purpose processors with Network Function Virtualization (NFV) support. The optical transport network connects the RRU and BBU. Multiple BBUs in the BBU pool are connected together through high-bandwidth switches with Software Defined Network (SDN) support. By using NFV and SDN in combination, resource sharing and dynamic scheduling in the BBU pool can be achieved to increase spectrum utilization efficiency. Compared to the traditional RAN architecture, C-RAN eliminates the constraint that the RRU and BBU must be deployed close to each other and also centralizes the BBU of various base stations into a single district tandem office. The application of C-RAN will reduce the construction and maintenance costs of telecom rooms and increase spectral efficiency through collaboration methods and virtualization technologies.
