Summary:
Carriers deployed 5G backhaul network towards multi-protocol label switching network with fixed-mobile convergence. With the demands and development of new 5G application, 5G backhaul, which can be regarded as a Wide Area Network (WAN), requires to meet more bandwidth, low latency and scalability. Traditional wide area networks have the issues of high cost, low efficiency, and global optimization for multi-domain. The software-defined technology is introduced to the WAN, which is called WAN SDN controller, to satisfy the real-time and flexible requirements of 5G new service scenarios. To achieve next generation mobile network, telemetry and network observability is also important. In this paper, we propose a distributed architecture, applied to the real 5G networks, and analyze the amount of captured traffic data and delivery paths. Our solution deployed on 5G network in Chunghwa Telecom. The implemented outcomes show that the IP/MPLS networks automatically adjust to achieve closed-loop through WAN SDN controller. It lays the foundation for the goal of WAN autonomous networking.
