Examples

Here are some examples of traffic you can see while performing different operations in the browser.

Creating new tab

Mojo's Invitations mechanism in action, setting up the mojo channel in the new process.

Playing DRM-protected media (e.g Spotify, Netflix, ...)

The renderer sends encrypted audio to the Content Decryption Module (CDM) process, gets back decrypted audio, and then sends it to the Audio Service for playback.

The audio itself is passed over a mojo data pipe (shared memory).

Legacy IPC

Some components in Chrome still use the old IPC, such as Extensions and GPU process.
