+# Stream port name conventions
+
+## Summary
+[summary]: #summary
+
+Settle on and document name conventions for stream components.
+
+## Motivation
+[motivation]: #motivation
+
+Having a name convention for stream ports makes stream components easier to work with and allows automating the connection of pipelines like this:
+
+```
+pipeline = [component_a, component_b, component_c]
+for upstream, downstream in itertools.pairwise(pipeline):
+    wiring.connect(m, upstream.o, downstream.i)
+```
+
+## Guide- and reference-level explanation
+[guide-level-explanation]: #guide-level-explanation
+
+Document the following conventions:
+
+- Whenever the name of a stream member of the component interface includes an indication of its direction, the indication must match one of the following forms:
+  - For `In` members, either the complete name is `i` (for components that have one primary input), or the name must start with `i_` (for more complex components).
+  - For `Out` members, either the complete name is `o` (for components that have one primary input), or the name must start with `o_` (for more complex components).
+
+- It is also acceptable to have a name that doesn't indicate directionality explicitly, e.g. `requests` or `packets`.
+
+Update existing stream components to follow these conventions.
+
+## Drawbacks
+[drawbacks]: #drawbacks
+
+None.
+
+## Rationale and alternatives
+[rationale-and-alternatives]: #rationale-and-alternatives
+
+Without a common convention, components will be written with different naming schemes, requiring more care when interconnecting them.
+
+## Prior art
+[prior-art]: #prior-art
+
+Stream ports in LiteX components are conventionally named `sink` and `source`.
+
+## Unresolved questions
+[unresolved-questions]: #unresolved-questions
+
+None.
+
+## Future possibilities
+[future-possibilities]: #future-possibilities
+
+A `connect_pipeline()` function can be added that takes an iterable of components and connects them in sequence like shown above.
