Routers: What Are Jumbo Frames and why do I need them?
Some routers' specs specifically mention that they handle jumbo frames (with a number like 9K). I have a network with 2 iphones, two ipads, 4 computers, two networked Blu-Ray players, and 3 computers, all of which are operating simultaneously a lot of the time.
Some other companies seem to be using the fact that they support jumbo frames as part of their selling points. How do they help?
I asked Cisco Chat support about the RVS4000 and whether it supported them on both the WAN and the LAN. They said not on the WAN. They also said "
It appears under the L2 Switch tab you can input a Max Frame type.....
I don't see anything that actually says jumbo frames but I believe you can put in a value.....
after the device is setup you can navigate to the L2 Switch option and it has a Max Frame value"
I'm not sure whether this router supports jumbo frames or not. I have a short list of wired gigabit routers that I'm considering for purchase and the RVS4000 is on the list.
I need to learn more about this topic so any help or pointers to stuff to read would be greatly appreciated.
Re: Routers: What Are Jumbo Frames and why do I need them?
Thanks so much for the info. I read virtually all of it. The Jumbo Frames thing sounds very tricky - and possibly detrimental. I'll have to see if Time Warner Roadrunner supports them and at what sizes. Other than for really big file transfers between machines on my network (which I don't do that often) it sounds like jumbo frames isn't going to do much for me.
It also looks like the RVS4000 is not what I want. The smallnetbuilder review was a very useful one-although it's 4 yrs old, it's still likely mostly valid.
I do some gaming at times and it sounded like the adjusting of frame sizes until all the devices in the path are the same can cause unacceptable latency. Now it seems that no matter which gigabit router I choose, I need to be sure I get one where I can disable the major frames process, and maybe enable it when I want to do hard drive backups across the network. Welcome to the gigabit ethernet world I guess.
It also sounds like it's more complex to set up than I would like to tackle. I'm a retired electrical engineer but definitely not a skilled IT person, so plug and play simplicity is important. I understand just enough to get in trouble.
