Good Day

Just would like to find out if I am the only one in this boat

Our area is covered by Vuma and since day 1 have had isses. First of all we have 2 connections on our property one for main house and one for Cottage

Now here is where all the problems started.

When they first installed they swapped pairs around and they kept on saying that everything is right. Main house Afrihost Cottage with Cool Ideas

After been in a pain in the butt with them and refuse to let go the same day they sorted that out.

Everything goes smoothly for about 2 weeks then the following started happing

Connection to Vuma kept dropping from multiple houses in the area. Once again they refuse to accept fault and say it is the ISP. on our WA Group there was about 70 different people with easily about 8 or 9 different ISP's all connections were dropping. (But according to VUMA it is ISP)

Last week Wednesday it dropped for about an hour and now there is a few of us in area that speeds have degraded. mine dropped from 1000MB to 90MB Local and if go from JHB to Cape Town server do not even get 20MB Down

And that is through Various ISP's in the area where people have noticed the Drop in Speed.

and that is testing Directly through VUMA CPE.

Am I correct at saying that it is actually VUMA at fault or is it all the ISP's that is at fault actually limiting everyone's speed?
 
Are you trenched or running aerial fibre?

If aerial then it uses GPON and they take that and divide by say 32 houses.

So that's 2.5gbps / 1.25gbps divided by 32 - so that's say 70-80mbps down and 35-40mbps up if everyone is maxing their lines - which means you'll never see Gigabit at that rate.

If trenched and active ethernet, then that's a different story.

It is trenched thats why going off at them as it is Active Ethernet, I would understand more if it was Aerial but on Active they have no excuse but yea suppose thats Vuma service they provide.

Even GPON shouldn't give issues, sounds more like packet loss on the line.

@OP, run an mtr if you can.

same contention applies weather on AE or GPON

Not quite a true reflection to be honest

Don't worry, all 32/64 people are maxing their line at 100% all the time, 24/7/365, they're just constantly downloading and deleting that one file from a special special server, it's probably extra RAM.

In our area it is all old people and most people took betweeen 8 & 50 MB, there is only maybe 5 of us that are on 100 or 1000MB package

Are you on Ethernet? You'll probably have to run iPerf tests to isolate issues, can't really help as don't know how WebAfrica is set up on Vuma, you'd need an iPerf server that's e.g. in Teraco in a controlled environment.
You'll have to contact WebAfrica support, and I know, their support really sucks.

Can you run a speedtest from the vumatel portal on www.vumatel.net ? https://vumatel.co.za/files/VUMA-Quick-Start-Guide-R5.pdf
Just want to see if you're getting full speed there.

In regards to iPerf, the "easiest" way of doing so if you're on a windows 10 machine is to install windows subsystem for linux, and downloading and installing the linux iPerf test there and running it on it as the windows one has a couple of "bugs" that render it mostly useless.

My comment was a joke, a lot of people keep taking digs at GPON due to its shared nature without understanding that it really doesn't matter based on current ratios and speeds, that the backhaul being limited is a more likely culprit than the GPON technology being the bottleneck.
 
Suddenly today after load shedding everything came right and during load shedding the cabinet goes down of Vuma. So more than likely their equipment just needed a restart.

No man, you have the cat by the tail.

my semi-limited background states:




GPON in SA isn't split 32 ways, it's split 64 ways (at least).
1 x 32 way splitter in the field plus 1 x 2 way splitter in the aggregation, cabinet or POP..
64 ways.

transmissions (downstream) from the OLT port to the ONT is broadcast-based.
All ONT's receive all data (for all 128 or 64 users connected to the port) ALL of the time.
However, only the ONT with the correct address translates the data for its own end-user.
The rest of the ONT's that received the broadcast packets simply discard incorrectly addressed packets as it's not meant for them.

Transmissions (upstream) from ONT back to OLT is TDM-based. (TDM over WDM, remember the splitters cause WDM to take place)
Hence the difference between down and upstream speeds.

down = broadcast + WDM through the splitters.
Up = TDM through the splitters (time division multiplexing is the erason for half the speed)


The only time you'll notice performance degradation is when ALL of your users (who are connected to that one specific line card port (all 64 of them or all 128 of them) on the OLT) are downloading data at maxuimun line speed, AT THE EXACT SAME NANO-SECOND.



It is THIS basic assumption that is at the heart of GPON"s success:

All users are NEVER maxing out their connections at THE EXACT SAME NANO-SECOND




If however, you want to guarantee maximum line speed AT ALL TIMES then you need a "Committed Information Rate" link

"CIR" is EXPENSIVE (think leased lines, dedicated point to point)
Banks, corporations, government..

From Frogfoot FAQ:
Not at all. A splitter is essentially a prism, splitting light, and the first time we introduce a splitter is right at the node, where we create a 4:1 split. Closer to the houses, we add another splitter at 16:1, making the overall split on that route 64:1. Should there be a number of close neighbours who all order and make heavy use of 1Gbps services, we will remove the 4:1 splitter for that route, thus dropping the split for the route to 16:1. Because there is 2.5Gbps available, the possible contention is less than 10:1. Practically, it is highly unlikely that so many people will buy 1Gbps services, and if they do, just as unlikely that they will all be using the full 1Gbps at the same time. To use an "old school" analogy, there are not enough telephone trunk lines connecting the suburb's Telkom exchange to the rest of the world to allow every single resident to make an outgoing call at the same time. The economics of telecoms network engineering relies on contention ratios.
