Get 2 GB/s from 2 gigabit ports

[Joduk]

Hey, I just order a new box from my ISP wich will be able receive 2 GB/s from the fiber network. Unfortunately, this box only have 5 x 1 GB/s gigabit ports.

Is there a hardware or software solution to merge 2 ports of my box to get 2 GB/s on my computer ?

I'm pretty sure it's possible, but i don't find answer on the web and and i'm not very good in networking.

You can look into load balance equipment.  Is the ISP box a modem + router?. Also isn't it 2 Gb/s instead of 2GB/s?

[mariushm]

it's not GB/s , it's gbps

gpbs = gigabits per seconds  or 125 MB/s

 

2 gbps could very well mean you have 1 gbps download + 1 gbps upload = 2 gbps total

 

If it's true 2 gbps, I suppose you could build a pc to act as a router and install two ethernet cards in it, each going to a gigabit port in your box. The router software on the pc would route some connections through one ethernet cable and other connections on the other cable. So for example, you could have Steam download games through one ethernet card and do a software router and a download in Chrome could go through the other ethernet card to the box..

 

If the box supports trunking you may be able to connect 2 or 4 ethernet ports together and connect them to another switch that also supports trunking. You'll have 2 gbps or 4 gbps going to the switch.

From there, if the switch has 10 gbps ports, you could connect your pc to the switch at 10gbps.

What box?

What type of fiber? GPON or other PON? Ethernet?

 

What equipment are you using?

Theoretically you could get 0.25GB/s. A gigabit is an eighth of a gigabyte.

You're looking for link aggregation. You would need two gigabit cards in your computer. The question is if the ISP's router supports it.

 

As others have said, it's Gb/s not GB/s.

So, as said above. Get the units right. Are you getting actual symmetric 2Gbps up and down connection or 1 Gbps up and 1 Gbps down? If the latter, that box is fine for your needs. Ethernet ports can do full duplex meaning receive and transmit at full potential at the same time. And all those LACP (Link Aggregation) and other network stuff won't matter to you, you won't be bottlenecked.

 

Now, if you are however getting 2 Gbps up and 2 Gbps down, then the story is a bit different. With 1 Gbps ports, you will be limited to 1 Gbps up and 1 Gbps down. Remember, you get as much bandwidth as the weakest link can handle. Here we have two options how to handle this:

 

1) Link Aggregation (LACP). If you want to get full 2 Gbps to a single device, you need to set up LACP by using multiple 1 Gbps ports (most PC motherboards have that). Though take into account, that single connection/download (e.g. Steam game download) will still be limited to 1 Gbps, but multiple connections together (Steam game download + Origin game download) can see combined bandwidth of up to 2 Gbps, if the OS routes them via different interfaces. Or how many ports you add to the LACP. This requires that both the NIC(s) in your PC and on your router/switch support a common Link Aggregation protocol plus there is some experience needed to understand how it works and how to set it up.

 

2) Switching to 10 Gbps (or higher) devices/interfaces. This can give you 2 Gbps for single connection (if the other side can be reached at those speeds), but you need a 10 GbE NIC, 10 GbE router (and maybe a switch). These are costly, but prices have come down in the last year quite a bit. Also there's not much in the consumer market and may require higher understanding of networks.

If it were ethernet I'd get a 10GE switch with at least one fibre port on it and install a 10GE nic in the computer.

Thanks for all your answer, I will try to define more precisely my problem:

Yes sorry, it's 2 Gb/s, don't know why I write GB/s. 

By "box" i mean modem + routeur.

My ISP provide 2 Gb/s and 600mb/s (I think my ISP use GPON but i'm not sure) my goal is to use this bandwidth on my computer in one application.

The best solution will be an hardrware like a switch that will receive 2 x 1 Gb/s and can output 2 Gb/s on a 10Gbps interface.

 

If I understand right this solution will be a Link Aggregation in 10Gbps ?

What will I need and how much do you think it can cost ?

 

I already have some knowledge in networking, but like I said before this is not my main field (i'm a system admin)

 

Thanks again for your fast answer

LACP won't help here. If you want one program to work at great than 1gb/s you need some other server to put split the streams together. SOmething like network bonding or sdwan can do this.

 

Easier way is to try to replace that box with something with a 10g port or some interface that is faster than 2gb/s

 

What model is the box?

Often though if you get ethernet connection from your isp, there using something like 802.1x to keep random boxes from connecting to it, so you can't just plug your switch into their network, you still need their gateway. Many fiber services like att dedicated internet use all Ethernet for the connections, but you still need their boxes.

It's a brand new model of the french ISP "Orange", the model is "Livebox 5".

Replacing the box sound good, because their in-built OS doesn't offer lot of possibilities...

Do you have a model of routeur in mind ?

Im guessing this is a modem/router combo?

 

If so, call the isp and ask what modems you can use.

 

If its just gpon or some other pon, there are lots of ont's you can use, but get a list of ones that they approve.

Yes it's a modem/routeur combo, I'm pretty sure they use GPON but you are right, I will call them to be certain.

Thanks a lot for all your help, I have googled a lot tonight and I think that the best solution is change this box.
