This is a sub-selection from guaranteed bandwidth.

Re: guaranteed bandwidth.

said by Kamus:

So, basically you can guarantee 1 gbps at any given time to two 1gig Ethernet ports (2 desktops at full speed, all the time!)

It isn't guaranteed. The deployment uses GPON which means the 2.488/1.244Gbps feed gets split between 8 or more subscribers. The OLT at the other end likely has something like 10:1 oversubscription so you are not likely to get more than maybe 300Mbps during peak hours.

Outside North America, it is quite common for networks to operate under congested regime during peak hours. Running networks that way is much cheaper than trying to stay ahead of instantaneous peak load.

ahmm it's pretty common here in the us also. Every end user commercial service works like this.

What BosstonesOwn said as well as 300Mbps during peak time kicks the everloving crap out of your best case scenario on everything but the fastest muni or google FTTH installs.

300Mbps was an optimistic figure considering only the first two aggregation layers.

If you look at other high-speed low-cost providers like HKBN's 1Gbps for ~$35/month, peak-hour speeds to sites/services outside HKBN's own network drop to 30-70Mbps... and even within their own network, speeds do not seem to exceed 300Mbps very often. Of course, still beats the pants off anything we can get for $35/month here.

As for Google Fiber, there aren't enough people on it to draw conclusions yet but my hunch is it will turn out somewhat like HKBN if they roll it out to enough people for it to make a dent in Google's existing bandwidth pool.
