signalsbetween

Signalsbetween refers to the set of signals transmitted between two or more entities during an interaction, emphasizing the relationship, timing, and sequencing of those signals across a boundary such as processes, devices, or network nodes. The term is used across fields such as signal processing, distributed systems, and software engineering to describe how information flows between participants, rather than the content of any single signal.

Core concepts include sender and receiver identities, signal type or event category, payload, and metadata such as timestamps and sequence numbers. Attributes like latency, jitter, and order preservation are used to analyze correctness and performance.

Representation often takes the form of a structured record or log entry with fields such as sender_id, receiver_id, signal_type, payload, timestamp, sequence_id, and status. In streaming contexts, signalsbetween can be modeled as an interleaved stream of events or as separate channels for control and data.

Applications include inter-process communication within a computer system, cross-service messaging in microservices, telemetry in distributed sensors, and event tracing for debugging and performance monitoring. It also informs design choices around synchronization, fault tolerance, and backpressure.

Relation to related concepts: it overlaps with inter-process communication, message passing, event streams, and telemetry. It is distinct from the content of the signals themselves and focuses on the relationships and timing that govern how signals traverse a boundary.
