Winners and losers as S&P rebalances
SYDNEY airport operator MAp Airports looks to have been an early beneficiary of Standard & Poor’s decision to include it in the index of Australia’s 50 largest companies.
Gigabit switch, some 10/100 connections, some Gigabit…?
I have a few PC’s in my house and want them all connected to a server in my garage through a Gigabit switch. All have Gigabit Nics, so this shouldn’t be an issue…
However, I also want to make sure my TV’s, Blu Ray DVD players and media streamers are connected to the Net to download firmware updates, Blu-Ray Live content and are generally prepared for greater internet connection requirements from hardware of this type…
My worry is that if I connect the TV/DVD/Streamers, which are all 100Mbps, will the Gigabit devices still be able to operate at Gigabit speeds to each other? I understand that if I use the streamer (100Mbps) to pull media from the server (Gigabit) that I will only get 100Mbps (at best), but will the Gigabit devices be pulled down to 100Mbps by the slower devices connected to the switch?
I haven’t bought the switch yet, so if that does make a difference, it would be good to know what makes/models I should be looking at…
Thanks
The switch will pick the slowest “link” and adjust the speed only for the machines that are communicating. That is, if PC “A” is talking gigabit to PC “B”, they will stay at gigabit even though PC “C” is 100mbit and is talking to the router for internet.
Each port tries at the highest speed, but if the port it is talking to is slower, it will throttle just between the talking PCs to match the slower machine.
The same is NOT true for hubs, they run at one speed, as they cannot store and forward like switches can.
A switch is a store and forward device, it figures out each port on it’s own merits.

“3com superstack 3 switch 3848″ is a layer-2 or layer-3 switch?
Layer 2 switch. Check out the spec sheets below, I don’t see any routing protocols listed. It does mention up to 255 VLANs, so perhaps at the most it might do interVLAN routing.
