IFpath

IFpath, short for Information Flow Path, is a conceptual framework and accompanying software toolkit designed to model, analyze, and visualize paths through information-flow networks. It provides a formal representation of how information moves from sources to targets across directed graphs, enabling users to reason about path structure, reliability, and latency.

In IFpath, a network consists of nodes and directed edges. Edges carry attributes such as capacity (maximum information rate), delay, probability of successful transmission, and cost. A path is a sequence of edges connecting a source node to a destination node that satisfies user-defined constraints, such as maximum latency or minimum reliability. The framework supports abstractions for heterogeneous node types and modular edge semantics to reflect different information channels.

Core capabilities include path-finding algorithms (shortest path, widest path, minimum-cost path), path enumeration with constraint filtering, and simulation of flows along multiple paths. It handles cycles and parallel paths, with options to avoid dead ends or to model feedback. The toolkit typically supports exporting and importing path data in common formats and provides visualization components to illustrate path structures and flow dynamics.

IFpath is used in domains where tracking the movement of information is important, such as network analysis, security auditing, epidemiology, supply-chain provenance, and software tracing. The project emphasizes interoperability and extensibility, with a focus on neutral representations that facilitate integration into analytics pipelines and other graph-based tools.
