Why does my internet connection feel slow and jumpy, even when my internet speed is high?

Of the 8.2 cardinal homes and businesses progressive connected Australia's National Broadband Network (NBN) successful July 2021, 77% are present reported to beryllium connected a broadband program that delivers speeds of astatine slightest 50 megabits per 2nd (Mbps). This is plentifulness to accommodate a emblematic household's needs for video streaming (Netflix high-definition resolution, for instance, uses astir 3Mbps and ultra-high explanation astir 12Mbps), video conferencing (2–3Mbps), gaming (less than 1Mbps) and wide web browsing.

So wherefore bash we inactive acquisition video freeze, crippled lag spikes, and teleconference stutters? The occupation is not speed, but different factors specified arsenic latency and loss, which are unrelated to speed.

For much than 3 decades we person been conditioned to deliberation of broadband successful presumption of Mbps. This made consciousness erstwhile we had dial-up internet, implicit which web pages took galore seconds to load, and erstwhile DSL lines could not enactment much than 1 video stream astatine a time.

But erstwhile speeds attack 100Mbps and beyond, studies from the Broadband Forum and others amusement that further increases are mostly imperceptible to users.

Yet Australian consumers fearfulness being caught abbreviated connected broadband speed. More than fractional a cardinal Australians moved to plans delivering more than 250Mbps successful the March 2021 quarter. Indeed, we person collectively bought astir 410 terabits per 2nd (Tbps) connected our velocity plans, portion existent usage peaks astatine 23Tbps. This suggests we collectively usage little than 6% of the velocity we wage for!

In opposition to our request for speed, our online clip has grown tremendously. According to the Australian Competition and Consumer Commission (ACCC), the mean Australian household consumed 355 gigabytes of information successful December 2020, a 59% summation connected the twelvemonth before.

Our net usage is similar a marathon runner gradually adding much and much miles to their grooming distances, alternatively than a sprinter reaching higher and higher apical speeds. It truthful makes small consciousness to justice our multi-hour marathon of video streaming, gaming and teleconferencing by moving a transportation velocity trial which is simply a 5-10 2nd sprint.

What bash we truly request from broadband?

So what bash we request from our broadband for a bully streaming, gaming oregon conferencing experience? A transportation that offers debased and comparatively changeless latency (the clip taken to determination information packets from the server to your house) and loss (the proportionality of information packets that are mislaid successful transit).

These factors successful crook beryllium connected however good your net work supplier (ISP) has engineered and tuned its network.

To trim latency, your ISP tin deploy section caches that store a transcript of the videos you privation to watch, and section crippled servers to big your favourite e-sport titles, thereby reducing the request for long-haul transport. They tin besides supply bully routing paths to servers, thereby avoiding poor-quality oregon congested links.

To negociate loss, ISPs "shape" their postulation by temporarily holding packets successful buffers to creaseless retired transient load spikes. But there's a earthy trade-off here: excessively overmuch smoothing holds packets back, starring to latency spikes that origin missed gunshots successful games and stutters successful conferences. Too small smoothing, connected the different hand, causes buffers to overflow and packets to beryllium lost, which puts the brakes connected downloads.

ISPs truthful person to tune their web to equilibrium show crossed the assorted applications. But with the ACCC's Measuring Broadband Australia (MBA) Program predominantly focused connected speed-testing, and with a 1% borderline separating the apical 3 ISPs each keen to assertion the apical spot, we are inadvertently incentivising ISPs to optimize their web for speed, alternatively than for different factors.

This is simply a detrimental result for users, due to the fact that we don't truly person rather the request for velocity we deliberation we do.

How tin we bash better?

An alternate attack is possible. With advances successful artificial quality (AI) technology, it is present becoming imaginable to analyse web postulation streams to measure users' acquisition successful an application-aware manner.

For example, AI engines trained connected the signifier of video "chunk" fetches of on-demand streams specified arsenic Netflix, and live streams specified arsenic Twitch, tin infer whether they are playing astatine the champion disposable solution and without freeze.

Similarly, AI engines tin analyze traffic passim the assorted stages of games specified arsenic CounterStrike, Call of Duty oregon Dota2 to way issues specified arsenic lag spikes. And they tin observe videoconferencing stutters and dropouts by analyzing postulation connected Zoom, Teams, and different platforms.

Australia has made important nationalist concern into a nationalist broadband infrastructure that is present good equipped to supply more-than-adequate velocity to citizens, arsenic agelong arsenic it runs arsenic efficiently arsenic possible.
