JJ32 gave me an intriuging idea...

[HELLBRINGER 0]

From his recent thread start. I had an intriuging idea.

 

I don't know if it will work or even can. But... Could you take 2 switches, and two network cards. And 2 NICs in each comp on the network. And run both as a multi-link type of thing? Combining the speed of two switches together and the speed of two NICs together. Would this work or can even be done? I know its far off base for the switches.

 

You can do this with modems I kow. Can it be done with NICs? How about switches/hubs?

 

Hehe sorry I though it was a good idea...

Yes... I'd say so. There is software out there that lets you combine connections together. A friend uses such a thing on her ISDN and modem connections.

Well, using multiple NICs in that arrangement would be "Load Balancing". As for the 2 switches part, why use 2 switches? If there are 2 PCs using load balancing, and they wanted to connect to each other, just use a switch that has at least 4 ports plus whatever other ports you need for the rest of you network (such as "uplink" to another segment or device). However, I don't know if this is available for Win2K Pro since it's the workstation version of the OS.

 

With ISDN, it's called "Channel Bonding" and is a built-in function of the protocol. "Multi-link" or the trade name "Shotgun" protocols were to act in a similar fashion with POTS modems and would theoretically double the available bandwidth.

[HELLBRINGER 0]

Yeah I kinda saw a lot of this with modems.

 

The reason for 2 switches I guess is more throughput. But I would need 4 switches then... Cause I got 5 computers on the network and a 5 port switch.

 

Hmmm... Interesting. I think I will give the 2 NICs a try... Or... I got 2 extra 10MBPS cards... Hmmmm. ;-)

 

Thanks guys.

The switches would maintain 100Mbs per port anyway, so that wouldn't make any difference. Plus, NICs rarely hold their rated bandwidth anyway. That's mostly due to the OS though.

[HELLBRINGER 0]

Yes i know the ports would remain 100MBPS. But with 2 NICs, and 2 cables from 1 computer using 2 ports on a switch. Or.... 2 NICs and 2 cables in 1 PC and 1 cable going to one switch and the other to the other switch and the two switches connnected together combining their speed.

 

Kind of like full duplex but full duplex seems wierd and doesnt feel like 200MBPS, actually it seems slower sometimes. How does that work anyway?

Nope would not work with SW alone.

You need something link Compaq NIC Teaming or the equivalent from HP.

Because cards have to be able to communicate wih each other via DMA

It is basicly the same technology that they used on w95 for multi modem link.

 

If anybody needs more BW change your cables, routers or get Fiber

Real 1GB/ps should be enough for any of you

[HELLBRINGER 0]

Damn... But some of it could be done.

[Uykucu 0]

All of it can be done,

Get the necessary Nic's

or a Compaq server. Once you are at it why don't you cluster as well )

[Cynan 0]

The S/W is there, trust me, its called multipoint or something, I'll post the link in here later. It can be run on 2K Pro to balancing the load across two or more interfaces.

[HELLBRINGER 0]

Ok cool well I was just wondering. If it is a decent price I will probably do it.

 

Thanks

Himm yes SW claims to be here but how does it work? has anyone tryed it? and how does it manage which packet comes from which NIC. driver has to support this and even the card. so we are back to Sq one in my opinion.

It might be good for traffic control and such but can it combine BW's or Separate them to channels in that sense???

[Cynan 0]

My friend uses it, it balances the load across them.

[Uykucu 0]

Yes of course any SW can do that but I believe Hellbringer's idea was to combine the BW of 2 Nic's and get a cheaper 400 Mbit or whatever.

I will have a look at it this weekend.

[Cynan 0]

You can't do that with hardware - I don't think. The way you work around it is to use threads when transfering the data, like when bounding DSL connections.

[HELLBRINGER 0]

Well I think there is special software to take the packets and split them into 2 smaller packets and 1 goes to 1 nic and one goes to another.

 

I know this can be done. But I wanna see if two switches can be used as 1 with twice the throughput.

 

Like RAID 0. Data stripping takes the data and it is split and part goes to on HD and the other goes to another HD.

 

Kind of like that?

[Uykucu 0]

Well,

This is what I mean. What you are asking can not be done without the appropriate NIC's

[HELLBRINGER 0]

Yeah I figured that... But it's just an idea, dont need to take it to an extreme conversation.

 

I bet though if you put a little money, and time into it it could be done. And I think it would be quite impressive. Don't you?

[clutch 1]

Well, load-balancing works fine in servers, and is an installable option on Win2K Advanced/Enterprise Server and Windows 2000 Server if Application Server is installed. However, the general idea is "why bother?" when this is applied to workstations. Also, some applications may not take kindly to NLB, so this may still not be such a hot idea. Basically, go Giga-bit.

[Uykucu 0]

Just got back from Network troublshooting of 4 hours.

Bloody London is burning up, Underground is verry hot and the office I was in did not have air conditioning.

Frankly Go 5 Giga Bit if you like to....

 

BTW Does anybody know a Lotus Computers based on Holborn or use to be... Please send me the adress so I can send the bastards a mail bomb or something.

 

What Kind of idiot will cross connect UTP cables, tape them and hide them behind a cabinet. Of course tape detoriated and caused a short. took me 2 hours to figure it out.

 

 

PS. If you are the lotus Computers I invoite you for a duel...

[HELLBRINGER 0]

Ahhh yes, but can't do it now. Was just an idea. Don't have the money. Not worth the money either at this point.

 

Man that sucks! Cable taped! LOL! Idiots! Better yet why don't they just staple it! LOL sorry.
