Generic jumbo frame setup

New Around Here
Hello all!

I would like to utilize the speed of jumbo frames when moving files from my jumbo-capable computer to my jumbo-capable NAS. At the same time, I want to use non-jumbo frames for other activities such as streaming TV via my non-jumbo-capable Slingbox to my computer, or accessing Internet.

What is a good switch-router configuration for mixed jumbo/non-jumbo environments?

My current setup below. Switch 1 and switch 2, in separate rooms, are connected via a gigabit cable. The switches are unmanaged, e.g. non-layer2/3.

--- SWITCH 1 connections ---
- Playstation 3: gigabit, non-jumbo-capable. Needs to be able to access Internet and NAS (photos etc).
- TVIX mediaplayer: gigabit, non-jumbo-capable. Needs to be able to access Internet and NAS.
- QNAP NAS: gigabit, jumbo-capable. Needs to be able to access Internet and to be able to be accessed by computer.
- Slingbox: non-gigabit, non-jumbo-capable. Needs to be able to access Internet and to be accessed by computer.
- Nintendo Wii: non-gigabit, non-jumbo-capable. Needs to be able to access Internet.
- Internet router: currently non-jumbo-capable.

--- SWITCH 2 connections ---
- Belkin network USB hub: non-gigabit, non-jumbo-capable. Accessed by computer. Connects various USB devices.
- Computer: gigabit, jumbo-capable. Needs to be able to access Internet, NAS, Slingbox and networked USB hub.

From what I've read, I cannot mix active jumbo and non-jumbo units on the same IP subnet due to how the IP protocol is implemented. Hence I would need two subnets: one subnet (A) with jumbo devices and one subnet (B) with non-jumbo devices. Devices on A need to interact with devices on B and vice versa.

My assumption is I need either ...

1.) A jumbo-capable, dual-subnet-capable Internet router. The router would deal with traffic in between A and B, along with Internet traffic.

2.) Two jumbo-capable layer3-capable switches (very expensive). The L3 capabilities within the switches would deal with routing in between A and B.

3.) A separate, added, jumbo-capable router dealing with routing between A and B. This eliminates the need for a dual-subnet-capable Internet router.

Note: Layer2-capable switches may possibly be added to separate A and B, using VLANs.
Is this needed, or can I separate A and B by merely using different IP subnets?

All in all, what is the best way to get going with jumbo frames having the needs above?

Thanks

Yes, I have read those (splendid) articles. As the mixed-networks one was written in 2007, is there any new hardware to be used?

Thanks,
Ulf
 
There are plenty of new switches. But the basic jumbo frame mechanisms haven't changed.
