US 8,576,991 B2 · End-to-end logic tracing of complex call flows in a distributed call system

Abstract

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.

Dependent claims

A method of embedding in band call flow logic history within a call request for passage through a distributed call system, said method comprising:

embedding a first group of characters representing specific events in a logic flow of said call request, relevant to a first component device in said distributed call system;
embedding a second group of characters representing specific events in said logic flow of said call request, relevant to a second component device in said distributed call system;
and
communicating said first group of characters and said second group of characters are communicated in-band within said call request as said call request traverses said distributed call system;
and
wherein said specific events are unique with respect to any given component encountered during said call flow.
