End-to-end logic tracing of complex call flows in a distributed call system
A logic history can be provided for every request or call instance through a distributed computing system that uniquely traces its entire path, end-to-end, in-band within the messaging for the system. The end result is a single true representation of what occurred with no post computational inference. Accordingly, unique logic history codes are not forced across the system. Rather sub-components that are logic history enabled can use codes that have meaning and applicability to itself. Unique logic history codes are not forced across the system, which in practice would be brittle. Rather each sub-component that is logic history enabled can use codes that have meaning and applicability only to itself. This allows the system to be flexible and lets sub-components change and redefine their logic and logic history traces without impacting the rest of the system.
1. A system to embed a logic history in a routed message through a distributed computing system, comprising:
