Excitel Fiber Broadband Experience in Delhi NCR

Yep, after the upgrades, it's happening.

Then they've really messed up something...

It's just it, they are overselling what little capacity they have. Even downloading from the nearest IX, speeds are not up to mark and it's not just any server it's Akamai.

@Lolita_Magnum I have a question to ask, what combination will be best for good routing(pings, page load times, streaming etc) 1. Huawei ONT 2. Huawei ONT in bridge with TP-Link archer c6v3 running openwrt. 3. Zte ONT only.

For my situation and from what I have experienced, since router we use is pretty much in the pleb category (ie. since it defaults routes all packets to the ISP gateway instead of working like a BNG), it wouldn't really matter what you use on your side.
Test all configurations and use what you think is the best for your use case the only difference you'd see is the speeds and latency on Wifi and that too if you have too many devices interacting.

I don't see any performance difference using/or not OpenWrt but the reason I am using is that -
1. I wanted to use secured DNS on the router level and also wanted some freedom with modifying the IPs of some domains and blocking some.
2. OpenVPN, TP-Link had a speed limit of 20Mbps on stock, this does a lot better.
3. I am able to use dynv6 as DDNS.
4. The load balancer thing I mentioned previously.
5. And a lot more.

I have a TPLINK Archer A6 and not C6 so I cannot vouch for that, TP-Link A6 v3 is Mediatek dual-core and even after throwing so much at it, it usually stays at about 1-5% and 40% when using VPN.

Thank you bro.

Excitel ground guy explained me their network topology. They use GPON so they can have up to 128 users per port. They first take one fiber from OLT port and then use 1:8 splitter outside their office and have 8 main lines from 1 port. Then they take those main lines & take it to the area where their customers are and there they add 1:16 splitter to each line (which was already splitted into 8) so from each main line they can give maximum 16 connections. Also if we do the math 8×16=128 connections per OLT port. That's how their ground level system works. Per 16 Port OLT they can technically give upto 2048 connections. I asked about uplink and he said technically it's 48 Gbps but by using SFP+ module only (4 ports) they can get 40 Gbps uplink. But guys the main thing is how can they serve 2048 connections with just 40 Gig? I mean it's theoretical maximum but 40 Gbps for around 2000 connections is less. What if everyone starts downloading at the same time? Boom.

If we do the math by having total throughput 5000 MB/s divided by number of users 2000 we get 2.5 MB/s. Means per user will only get around 20 Mbps.

Is this the reason they are not giving Gig plans? Because if even 40 people saturate the connection once everyone will suffer? Is this 128 connections per port method suffers at 1 Gig? Also what's the maximum bandwidth of their GPON port? Is it 10 Gig? Thanks....

Per GPON max speed is 2.5gbps d and 1.25 up

 

[havoc]

So for 128 customers it's just 2.5 down & 1.25 up?

If that's the case now I understood why 1 Gig is hard

Imagine 6 people using 400Mbps using their full speed, nothing left for rest 122 users. ;(
