5G integrated transport solutions and key technologies based on OTN evolution

As a new generation of mobile communication standards, 5G becomes a hotspot in the industry. The 5G network provides eMBB (enhanced Mobile Broadband), uRLLC (ultra Reliable & Low Latency Communication) and mMTC (massive Machine Type of Communication) services, and has new requirements of transport networks for bandwidth, capacity, latency and networking flexibility. At present, the main solutions to 5G transport are SPN over OTN, IPRAN over OTN, and packet-enhanced OTN. This paper focuses on the key requirements of 5G transport networks, 5G packet-enhanced OTN transport solution, key technologies and standard progress.
