So a guy from Virgin rang me to get feedback around cancellation I told him about this forum, BQM’s, copper coaxial Vs Fibre and DOCSIS. Told him about my terrible gaming experience. He said it’s a lie that virgin isn’t fibre and my understanding is incorrect because and I quote ‘how else would we be able to deliver 1gig!’ … ok then. I explained that a copper coaxial can also deliver 1gig and it uses DOCSIS (which is the issue) and that is a completely different technology standard from a non copper fibre optic cable (True Full Fibre). He told me again my understanding is wrong and that cables makes no difference whatsoever and it’s equipment that does LOL 😂😂😂
--He's a retentions guy, so not a surprise he's no expert. VM actually have 2 million premises served by DoCSIS over Fibre to the Home just FYI. RFoG, RF over Glass.
Why are you blaming DoCSIS for your issues?
At this point I realised I was talking with an idiot but anyway I continued The call.
---Or someone who knew VM have built to 2 million premises of full fibre and was a little confused.
... he didn’t really have a come back so I thought I’d try to educate him, I again mentioned DOCSIS but he kept deflecting, I then said right down on your feedback sheet one single word and spelled it out for him like a child D O C S I S and said that word IS NOT fibre.
--He's a retentions agent. He knows they have the same Superhubs at full fibre homes as they do older school networks. So presumably the same standards.
I told him I work in IT and have a COMPTIA networking qualification, I am right, he is wrong. Finally I said Google DOCSIS and learn something. And hung up.
--You used an entry level qualification in an argument from authority. Your brandishing that makes you sound pretty junior. You're a little low in the chain to punch down. I am too, which is why I never patronise or try and educate these guys I just inform I'm off to a superior service. If need be I play the IT worker card and say I need better performance, they need no details and will only get them if they ask.
I’m so glad I’m leaving haha.
--Seems the right time.
I've replied to a couple of your posts where you've claimed extreme latency and jitter are normal in DoCSIS networks. They are not. 2-4 ms extra latency relative to GPON, XGSPON, etc if it's all working right, less than 1 in LLD mode, jitter depends on network load but 2-4 ms - the extra latency I talked about is about right. I was able to hit my CMTS from my 3.0 modem, no routers given for 3.0 then, first install on hubsite, at 5 ms. No real jitter, occasionally ended up at 4 or 6 but 5 nearly every time
You know DoCSIS, right. Explain to me, like I'm a VM retentions guy, why I wasn't seeing the latency and jitter you think are a systemic flaw in DoCSIS networks. Maybe why I was seeing 4s and 6s.
XGSPON first hop by the way:
10 of 10 packets received 0 % packet loss Min: 0.563 ms Avg: 0.703 ms Max: 0.797 ms
In any case I'm delighted with my full fibre connection. Like VM's upcoming symmetrical services on their XGSPON same speed both ways, and in my case that's 8-8.3 Gbps. I'm also delighted with my backup 550/75 link that can cut in and take over, depending on reason for failure, in between 1 and 8 seconds, and the 25 Gbit connections I have in the switching spine enough clear for 10G devices to max out on internal transactions while others can use the broadband connections. Indeed both of them if traffic is really high, it'll waterfall from one circuit into the other.
Anyway here's what the latency looks like from West Yorkshire. I take a trip over a 100 Gb link to Manchester where I join the Internet and either go off there or, as in the case here, to London.
BQM - Aware it has an IP: don't care.
