Trust scoring with intelligent traffic flow and load balancing in a network

A system and method are provided for routing traffic through a network to ensure load balancing and avoid untrustworthy nodes. Based on network data (e.g., telemetry data), a machine learning model generates trust scores, which are used for routing decisions by determining preferred routes from a source to a destination. The trust scores for nodes along a potential route can be combined into a cumulative trust score. The potential route with the lowest cumulative trust score (i.e., most trustworthy) is preferred, when all other factors are equal. Traffic is routed along the preferred routes, until their capacity is exceeded. Then to achieve load balancing, traffic flows are extended to the next most preferred routes (e.g., the next lowest cumulative trust score), and so forth. When traffic flows include a mix of sensitive and non-sensitive data, the sensitive data is preferentially directed along the most preferred routes.
