Jio Fiber is having issues with US traffic since last evening

@Lobogris so in an area if more than. 3people have 1 gbps speed plans then it will be saturated isn't it and there will be no bandwidth available for other small users right..

not only Jio but Local Internet providers also facing the same issues from today morning. I am barely able to access my AWS Workspace which is hosted in the North Virginia region. Lagging too much.

My instances are in NY and CA. Both were almost inaccessible in the morning

Your local provider might be using Airtel for thier backbone.

Well, it is presumably split up to 32 (unless Jio is cheap) but currently they might not have all 32 slots taken.
Now all ISPs oversubscribe bandwidth as normally not all users are online at the same time and they all don’t max out their connection all the time.
So if we have a typical scenario, there is unlikely to be more than 1 or at max 2 Gbps subscribers on the same GPON as the plans are expensive. Even if we have 3 of them, they probably won’t be online at the same time and hopefully won’t be engaging in heavy downloading at the same time. There aren’t many possibilities of actually maxing out 1Gbps in daily life in any case. Jio might have deployed 10-Gpons as well as they are a relatively new network and are offering Gbps plans.

@Lobogris No one knows thier tech properly.
Jio is trying to be the Apple of ISP's.

Isnt the 2.5gbps down and 1.25 gbps up speeds limited at ONT port only? Fiber cables itself can carry terabits per second data, isn't it?

 

[vignesh_venkatesan]

@vishalrao Yes, fiber can carry much higher traffic but there are more complicated multiplexers involved with higher traffic.
Each GPON port on OLT has 2.5 Gbps downstream and 1.5 Gbps upstream bandwidth.

Yes the limit is per port, and some thing that didn't occur to me earlier is that, the cable itself has multiple strands, so it is possible for an operator to attach each strand to a different port on the OLT. There is no significant additional cost for that. Then he could connect different customers to different strands depending on the load.

My point being, the operator wouldn't need to run a separate cable to serve a dense area.

Probably it's obvious, but it didn't occur to me until recently and was always thinking that if the link is saturated, the operator would need to run a totally separate cable and hence maintain multiple cables.

On re-reading this. The limit is for that given OLT port not ONT, so all customers connected to that port shares the 2.5/1.25 Gbps.
