Security system for managing 5G network traffic background
The technology includes a method performed by a system of a telecommunications network to manage network traffic of a 5G network. The system can instantiate a security system to sort incoming or outgoing network traffic at a perimeter of the 5G network into multiple groups that are each uniquely associated with multiple traffic types and multiple security levels. The system can inspect segments of data included in the incoming network traffic and sort multiple portions of the network traffic into the groups based in part on the inspection of the segments of the data. The system can dynamically adjust an available bandwidth of the 5G network based on each load of each of the groups and dispatch the portions of the network traffic in accordance with a traffic type and a security level of each of the groups.
