Module transport

Transport Module

This module provides the networking and communication layer for the trace2e framework, enabling distributed traceability operations between middleware instances across different nodes in a networked environment.

Overview

The transport layer abstracts the underlying communication mechanisms used for machine-to-machine (M2M) interactions in the trace2e system. It supports multiple transport implementations including gRPC for production environments, loopback and no-op for testing purposes.

Transport Implementations

• gRPC Transport: Production-ready implementation using Protocol Buffers and gRPC
• Loopback Transport: Local testing implementation that routes calls internally between mock middleware instances
• No-op Transport: Stub implementation that performs no actual communication

Remote IP Evaluation

The module provides utilities for extracting remote IP addresses from M2M requests, enabling proper routing and connection management for distributed operations.

Architecture

The transport layer operates between the traceability middleware instances, facilitating the exchange of compliance policies, provenance information, and authorization decisions across network boundaries.
