Network Topology

[john h owen]

Has anyone as a matter of interest wired a network in the Ring Topology if so what Media was used?i

Did quite a few wireless rings a number of years ago when I was rigging Data radios, each node had a managed switch which linked in the local wireless WAN's on point to multipoint network and wired LAN's over a point to point radios

Used to use coax cable to wire ring networks, many many years ago now.

Use to wire the old Token Ring which if I remember correctly was classed as a ring topology but was usually wired as a star system out from the MAU's, using IBM Type1 cable and was good for 16Mb. At the time ethernet was only around 10Mb using thinnet coax cable, this was wired in a radial up to around 185m and had Tee pieces to connect to the back of the NIC card and 50ohm resistors either end to stop reflections.

Hello Members,


In addition to understanding performance issues, you also need to know how topology impacts network implementation through media type and cost. Different network layouts use different media types or materials. You will learn more about these different topologies later in the module. For example, thin coaxial cable is usually associated with the linear bus topology, while unshielded twisted pair cable is associated with the star bus topology. The type of cabling you wish to use for the network may determine the topology you will implement.



Thanks and Regards,

Blimey that takes me back.....I think the thin- net topology was called a bus....and for larger networks with hundreds of PC's we used to 'tap in ' to a larger thick cable called a hose in America or thick- net in the uk. Attached to the thick- net used to be a bee sting and an AUI cable that fed the local hubs.


Most modern networks are star topology with fibre back-bones.

There are so many different topologies for all the other networks and you just need to get expert in that!!

some people do jabber on here.....

We once installed an FDDI fibre ring, many years ago now, and ring topology is effectively redundant. Even Token ring uses star wired runs of data cable and the Token ring switch just makes a ring of the pairs. FYI
