Switch Fabric

[Jared_1]

So I was looking for a new switch and I settled upon the TEG-S80g. It has 8 gigabit ports. I noticed the thing has 16gbps Switch Fabric. What is that exactly?

Switching fabric is just a fancy way to describe the hardware and -to a degree- the software included in transferring data within the device but not between devices. The fact that it can handle 16Gbps means that the internal workings of the device won't bottleneck even at maximum load. 8  ports, 1Gbps each, two ways = 16Gbps.

Thanks!

You guys might want to read: http://etherealmind.com/what-is-the-definition-of-switch-fabric/ 

It CAN also refer to a set of redundant switches/routers connecting multiple hosts to a SAN (https://en.wikipedia.org/wiki/Switched_fabric).

 

But yes, Naeaes, is correct in this case, but not 100%. The TEG-S80G uses a Shared/Star Bus, and CSMA/CD. sure the internal network can throughput 16gbps, but if 2 or more ports send the signal at the exact same time there will be degraded performance (this being a consumer application, you probably wont notice..

CSMA/CD is defunct in modern Ethernet standards. The idea of hubs, repeaters and half-duplex died many many years ago. The TEG-S80G is a switch and is full-duplex, each port is it's own collision domain. CSMA/CD would never apply unless for some extremely rare reason his devices/ports were operating in 10/100BASE-T half-duplex mode, 1000BASE-T also does not even have the principle of half-duplex as data is transmitted on all four pairs in both directions at the same time.
