new samsung boxes more trouble then they worth? - Page 3

Just been running Azureus, and with it running, but with bandwidth spare, I cant get on virtually any websites.

I know its not bandwidth related, because I couldn't even reach my router setup page, and thats on a 100Mbit network.

I'm using a pace 2000 STB for my broadband, but its nothing to do with that, as I should be able to reach the router page regardless of the WAN connection type.

It seems Azureus seriously hogs networking resources. As soon as I shut it down, everything went back to normal.

This is on my missus PC, which is only a 1ghz athlon 512MB ram, win2k SP4.

Also, hows your PC CPU and RAM doing when you're doing a lot of P2P? What's the actual bandwidth usage?

(Had to vote 'no' btw, I know the technical details of why they're better

).

On the Samsung STB`s your BB usage shouldnt effect the TV as (i beleive) the Samsung has a seperate CPU for the BB conection and another for the TV conection (unlike the Pace STB)(please correct me if im wrong)(as have had a rather large amount of vodka)(inafct rather cheap vodka)(....must stop using commas for no reason........................)

Thats correct - samsungs have seperatue processors for broadband / broadcast.

You must be drunk - there isn't a single comma in your post

I think I know what the problem is, regarding slow pages with azureus running. Its todo with the amount of network connections used. There are limits in windows, routers, and most likely the cable modems, as to how many connections you can sustain at a time.

Having azureus use most of these connections for itself, results in webpages having to load everything through a single connection, which is not how a web page normally loads. It normally downloads all the images, and seperate frames simultaneously using many connections.

I had an old Belkin router that would crash everytime I used CounterStrike server browser, because it opened too many connections.

Does anyone know the maximum number of connections supported by STB and SA cable modems, or on the ntl network ?

I don't know if its the cause of everyones problems, but I do know my problem is down to packet loss when using the samsung STB, not the number of simultaneous P2P network connections made. Packet loss occurs whenever I'm doing any up/down loading, be it P2P, FTP, downloading from a website etc. I'm told this is a known problem with the samsung STBs, which is being investigated......

Nutty, if you're on samsung STB BB, try doing a continuous ping to www.bbc.co.uk (ping -t www.bbc.co.uk), then set a large (3-4 MB) FTP upload (for example to your webspace)away with no P2P running . Watch those packets drop

I'm on a PACE 2000 unfortunately.
Was thinking of upgrading to 1.5meg for a bit, to get a nice samsung box, but I dunno now.. You've put me off..

Nutty · 25-08-2004, 21:08

BTW, I'm sure someone on these boards said, that ping requests were low priority, so chances are UBR's or routers will drop them, if they're being hammered by heavy use.

Maybe pinging isn't the best way to look for packet loss?

I have had the new Sammy box installed, and i beleive the problem were all having is duplex Missmatch, basically ive heard from someone i know at NTL that the Samsung boxes work better on Half duplex, instead of full, which maybe why were getting all these problems, thing is that my Router cannot be changed and most wont be able to be, if you have a network card try adjusting the duplex to 100 Half.

This is quite astonishing really considering its a new design, 100Mbps full duplex should be the norm, and i cannot understand why it should work better on 100 Half, unless the ethernet port on the box has been set for half.

Anyway we all need to look into this further....

what does Half duplex Do, what are its performance drop offs over Full duplex??

lsgworldl · 01-09-2004, 21:50

I have been with NTL 3 years with the blackl stb will they change that in the future and the cable box as well?

Scorpio · 02-09-2004, 18:12

Basically Half Duplex means the transmission of data can only happen one way at a time, eg send or receive, and full duplex is sending and receiving at the same time, this is probably why your P2P sharers are fooking up, as they upload and download at the same time.

PS ive asked for a seperate cable modem and NTL said i could have one free. There coming round next week to fit it.

MatTman · 03-09-2004, 06:38

but doesnt this render it impossible to play online games?? Xbox uses both the upstream and downstream constantly anlong with the pc games..

i play ww2online with Teamspeack and theres constantly Large ammounts of Downstream and upstream, if its really a Duplex problem it doesnt make sense at all.. My connection never dropped atall for a week then suddenly i get it 4 times in 2 days while not even using it, maybe the Upgrades are causing these annoymolies, Maybe your being unhooked from NTL's routers for a split second causing total loss of Downstream...

i played last night without any problems so it seems very random.

10Mb/half duplex is easily enough to handle full speed two-way transmissions at cable modem speeds. The half duplex bit happens a couple of layers below the actual protocols like TCP and UDP. In fact, TCP overheads are way more of a problem than any duplex settings.

The Samsung STB has a 100Mb ethernet port. The Paces all have 10Mb. It's possible that this would show up cabling issues if you suddenly started running at 100Mb on cabling that worked fine on 10. In any case, since 10/half is ample, you might as well set this and reduce the demands on your cabling.

(and yes, I know the box should work fine even at 100Mb on proper cable, that's what we're looking at).

Scorpio · 09-09-2004, 12:33

Mat @ Half duplex, the reason your gaming may work is because of the size of the packets being transmitted, when running half duplex, cabling is not an issue anything cat 5 or above i.e cat 5e or high band cat 6 will be able to transmit 100mbit through it, and most of us will be using patch leads or long network cables most definately cat5 or above, so the 10 mbit and 100mbit isnt an issue, its the half and full duplex issue, if your getting duplex missmatch, ie 1 end send and receiving and the other can only recieve or send at any one time, thats when collisions happen and the packets are dropped. Hence the poor P2P results as you upstream and downstream are getting battered as well as many different TCP / UDP ports being operating at the time.

The routers at the core site when NTL place them wont be the problem, as all there doing is routing the subnets, the DHCP servers at each core site lease you the IP and other relavent DNS and domain details. The problem wasnt around when we had the Pace Boxes, and ive had confirmation from NTL that it is a Duplux Issue.

Just thought I'd mention a tip for those with browsing probs whilst using Azureus. In Azureus, keep the configuration tab open, & when you want to do some browsing, change the UL speed limit from 0 to 5, then when you've finished browsing for the moment, just right click the box & Undo. When you want to browse again, just Undo again.

I'm on the 750k connection with a SB3100 SACM, BTW, incase anyone's interested.
