@IPFreely said: I'm in a Mustang trial area. I don't have VM and there's no VM cabling to my home. If there were it wouldn't be XGSPON, it'd be an inverted node and RFoG. Note the BQM was headed 'YouFibre'.
Response: My misunderstanding, yes i meant RFoG for mustang areas and assumed that's what you are using. Noted you are using YouFibre, which seems like some sort of insane set up way beyond the needs of a home user, or even a SME.
@IPFreely said: The 2-4 ms is factual. Perhaps you should've read up on DoCSIS as you suggested the VM guy should, then you'd know about the latency of the request-grant-transmit cycle. 4 ms give or take for a request on its own, going down to 2 if the request is encapsulated with an earlier transmission and is well timed as far as the next upstream MAP goes. All dependent on what VM's upstream MAP frequency is: I believe it's 4 ms.
Response:Yes, fully read up and aware of this. You are defending VM's network technology based on theoretical and best case scenario conditions which is a far cry from the real world. Mercedes says a C350e has an official fuel-efficiency figure of 134.5mpg yet in the real world people only get around 40mpg, this analogy is applicable to VM network and DoCSIS latency.
@IPFreely said: My Openreach FTTP, I've two connections, the Openreach FTTP has 6 ms higher latency than the YouFibre link, and the latency is nothing to do with FTTP, much as the higher latency seen on VM BQMs in areas that are working outside of the 2-4 ms of DoCSIS delay is nothing to do with DoCSIS. VM's network follows their cable network, it's not as direct as BT's.
Response: Firstly the VM BQM's we see working outside the 2-4ms of DoCSIS delay is coincidently a huge number of customers i would confidently say over 98% of the customers. so everyone. I understand that you are saying DoCSIS is not entirely to blame (although RF over copper inherently does have jitter) and that the directness of the network matters perhaps more (and the quality of the infrastructure along the way). which i agree.
Taking all this into consideration, we can see why VM's network is poop. The path of your data is not very direct at all, a simple tracert command can reveal this. Couple this with poor implementation of DoCSIS technology, with bad hardware in their comms cabinets and customer routers, along with bad homecooked firmware on their CMTS. Couple this with the fact that CMTS's are overloaded and neighbourhood lines are oversubscribed. It all adds up to a pretty unusable connection for gamers at peak times, and barley passable at non peak times, and that's if you are in a 'good' VM area.
Contrast this with the much simpler and direct openreach network, coupled with it's fibre optics cabling which are immune to interference, and pretty much resistance free, with consistently lower latency built in, key word here being consistently. You can see why there is such a difference to the real world experience of VM and openreach customers as objectively proven by the many BQM's posted here. And this is the bottom line that matters, the real world, not theory. In theory there's nothing wrong with a Coaxial/DoCSIS network, but in reality, there's a lot wrong with it, that's noticeable, as felt by myself and thousands of people in this forum.
Side Note FYI - You didn't hear this from me, but fibre optics (and silicon CPU's) were first discovered by humans when the US military recovered a downed Alien UFO in the 1950's and began investigating it, intelligence agency's then spun up companies like IBM with their 'R&D' departments so the technology could be introduced to society in a more subtle/slower/natural/believable way. bottom line is If fibre optics is good enough for advanced alien aircraft, its good enough for me, and is by far the most superior method of transmitting data along a cable currently present on earth.......and perhaps other more advanced planets too.
As for storage, the aliens use Crystal, otherwise known as 5D optical data storage to researchers on earth, although this 'new' 'discovery' is actually just a primitive 1st gen form of the Crystal tech that the aliens use. We are just begging to research it now, will probably be another 20 years before its mainstream, fully replacing Flash/HDD/Tape. But rest assured the intelligence agency's have known about it since at least the late 1960's.
Who knows what pre-existing Alien tech will be granted to us under the guise of 'research discovery' or 'invention' beyond that.
