Network Graph abbreviation: ALAT?

I have network graph enabled in-game for when problems happen. I have a couple of questions: ⚽ What is ALAT? I understand LAT (latency), but I can't figure what ALAT means. 🏈 Are there more detailed descriptions of what each of the abbreviations mean, particularly for those of us like me who are somewhat technically challenged?

Here's an example of the graph from a recent game.

Thanks!
