Summary:
|
Scenarios in various vertical industries have differentiated SLA requirements for bandwidth, latency, and reliability, bringing a large number of different bandwidth, data security isolation, deterministic low latency and highly reliable bearer requirements for bearer networks. However, the existing FlexE standard has a granularity of 5Gbps. If 5Gbps slices are deployed in the network to meet the needs of a large number of fine-grained bandwidth services, the utilization of network physical resources will be extremely low, and large-scale deployment in operator networks is not possible. Therefore, it is necessary to study how to provide customers with fine-grained network slicing that accurately matches service bandwidth (M bit/s-level), delay and security requirements in bearer network.
