Packet Interface

1. Packets provide a way of modeling data inside the network of components you create with the Pypes Visual Design Studio. Packets are modeled in JSON because it’s a standard, efficient representation that works well with Python.

4. Writing custom components is really about understand how to work with packets. Your component will receive packets on its input port/s and will be expected to place packets on its output port/s. The logic the component provides will ultimately operate on each packet using the provided API. I think that most will find the API to be intuitive, flexible, and easy to work with.
