Salsify – A New Architecture for Real-time Internet Video

Barely related to this, but looking at the results (section 5.2) I'm amazed at how much worse T-Mobile is for latency. AT&T and Verizon both give about 2 s of delay for Hangouts, while T-Mobile gives 7 s of delay.

The reason T-Mobile looks so bad is because the T-Mobile trace was from a 3G network with very poor conditions, while the others (AT&T and Verizon) were from LTE networks under relatively good conditions. You shouldn't compare the quality of the carriers from our results.

Darn, I forgot UMTS was 3G. I think I was confusing it with HSPA+ (which I guess isn't really 4G either). Great work on the project.

Almost all telecom's network service will vary depending on specific location. Instead of X has better latency than Y, the correct conclusion should be that X has better network _in this particular location_ than Y.

T-Mobile aims for the Walmart positioning and Verizon the Neiman Marcus positioning.
