A method and system for predictive and validated bounded latency in a packet transmission network. The predictive and validated bounded latency is achieved by a combination of several network protocols referencing network level information monitored and controlled by a network controller external to each network device, including multi-level admission control, predictive data path computation, instrumentation built into each network device of the packet transmission network, and a network level topology view. As new virtual circuit requests are received, the network controller identifies whether network resources are available to meet the virtual circuit parameters without exceeding the bounded latency of the network whereupon corrective actions are implemented to address network resource deficiencies, if necessary, prior to accepting the virtual circuit request. Upon acceptance, the network controller configures the network devices to support the accepted virtual circuit.

This invention discloses an interpretable fault diagnosis method for Software-Defined Packet Transport Networks (SPTN) based on a manifold learning-based confidence rule base (ML-BRB), belonging to the field of network fault diagnosis and interpretable artificial intelligence technology. Addressing the problems of BRB combinatorial explosion caused by high-dimensional coupling of SPTN network monitoring indicators and the loss of physical semantics of low-dimensional features after manifold dimensionality reduction, leading to the inability to initialize BRB parameters, this invention proposes the "SPTN network state manifold space hypothesis." It utilizes the t-SNE algorithm to map high-dimensional monitoring data to a low-dimensional manifold space. Based on manifold geometry and dynamic neighborhood statistics, it adaptively determines the initial parameters of the BRB, including adaptive adjustment of reference values ​​and confidence frequency estimation. Through the IF-THEN rule structure of the BRB model, it outputs fault types and confidence distributions with physical meaning, and uses the one-to-one correspondence between samples before and after dimensionality reduction to backtrack the original high-dimensional data, forming a diagnostic closed loop of "manifold decoupling—rule interpretation—sample backtracking." This invention achieves transparency and interpretability in the fault diagnosis process while ensuring diagnostic accuracy, meeting the stringent real-time requirement of 50ms switching in SPTN networks.
