How widely is this supported and does it have real world benefits?

I love my G.INP VDSL connection. It's a metric ton better than an Interleavings off ADSL/VDSL line (Direct Comparasion as both are identical latency)

 

 

 

G.INP with SRA goes a step further to be pretty hard to disconnect at all.

 

@bmarquis probably has some more technical numbers to quote, but personally i'd never go back if i had the option..

 

 

 

It's kinda a shame that G.INP isnt enabled on the non Vectored cards, I assume it isn't supported on those though.

Thanks @hio77 - I was hoping you would chip in.

 

What modem would you recommend for bridging? DV130 had been my go to choice but it appears this does not support G.INP.

Definitely has real world benefits as @hio77 stated.  Especially if the Modem supports G.INP in both directions.

 

Note that it is error correction. If there are no errors, there is no benefit.  It is local (DSLAM<->CPE) retransmission of packets with DSL layer errors.
It prevents some end-to-end TCP re-transmissions and destruction of UDP packets.

 

We're finding that most devices support it already. Particularly where they support vectoring.

Correct, some cards don't support G.INP, so it's tricky to have on some places, but not others depending on Linecard variant. 

 

Not necessarily technically difficult, but it just becomes an inconsistent experience.  It is enabled when vectoring is enabled.

 

 

 

Edit to add the error correction bit and fix typos.

Personally I'm using NF4V's, they are my favorite since the broadcom chipset is so exposed.

 

I had tinkered with the idea of swapping out to Spark Smart modems, but it changes how my scripts work.. Plus I'm actually about to drop my dsl lines as the WISP link is perfect now there and I'm moving to fibre...

 

 

 

The Key thing i notice with it is, Packetloss is near non existant. (aside from the expected outcome of Queues filling up).

 

my TCP/IP sessions just are so much more solid. no sawtoothing from packetloss like Interleavings off shows.


The other place i actually seriously notice it is in Overwatch of all things, Not in the actual gameplay (it hides it well) but in the warning icon for packetloss. Interleavings off shows it, G.INP doesnt.

 

It's the little things ;)

Update - I have had a discussion with Draytek tech support and to their credit I must say they were responsive. They have advised me it does not support G.INP in firmware 3.8.4m8 (latest release) but they send me some pre-release firmware which does support G.INP.

 

I found this increased the upload speed slightly at the expense of reduced download speed. This experience was inline with what I found with a Metanoia MT-5311 VDSL SFP (which also supports G.vector and G.inp) compared to the Draytek DV130 with 3.8.4m8.

the MT-5311 + RB4011 is my goto for VDSL - although I know @hio77 isn't a fan :P

I would be interested to know why @hio77

 

The 5311 worked for me. It's just not the best option to deploy for home users due to the cost of the SFP and a Mikrotik router (like the 4011) to suit.

Hi, at work I have a number of 5311's installed on HexS Mikrotiks, all doing >100down, up, they are on a mix of Voda and Spark as ISP. Only issue I have found is ISPs with PPPoE is they sometimes fail to reconnect, so I use the netwatch feature and run a script to drop and restart the ppp session.

Don't have the home users as we are strictly a Business IT Vendor/RSP - I am interested how you get on with the beta firmware for the DV130. I am guessing you spoke with someone at snappernet?

G.INP wont drop throughput speed... highly likely there is another variable at play here.

They get hot,they dont have any way to properly monitor, they dont have any sort of management or settings to change... what fun is a toy if you can poke, prod and twist it?..

I also have a spare Draytek 2760 sitting here unused since I moved to UFB. If anyone wanted to test with it or purchase it off me I would happily part with it.

Only worth it if you want half upload ;)
