Networking Topology

        Topology is Layout How networking devices are connected
                  Ring Topology

Ø  Speed 4 Mbps or 16 Mbps
Ø  MAU(Media Access Unit):-used in token ring networks to Physically interconnect networked devices
Ø  It also use FDDI (Fiber data distribution interface):- used in ring  topology and fiber optic cabling to support a speed of 100Mbps
Ø  Not Widely used in modern networks
Ø  Main two type : Logical topology and Physical topology

Ø  Logically :-
 Describe traffic flow in the network

In Token:-

Source Address
Destination Address

  Ø  We Circulate the token around the network and then any host gets the token it looks destination address if destination addresss match then its reach inside of token and process the data
  Ø  Now token data field empty if another host send the data it insert the data into token and token circulate around the network

Logically That how Token is work

  Ø  Physical Topology:-
      Describe how network devices physically connect

Bus Topology

Ø  Commonly use early Ethernet networks
Ø  Connect through BNC Connector
Ø  Used Coaxial cable {Two type}

Ø  Thinnet (10BASE2} :-
ü  Distance Limitation: 185 Meters
ü  Throughput : 10 Mbps
Ø  Thicknet (10BASE5):
ü  Distance Limitation: 500 Meters
ü  Throughput : 10 Mbps

Star Topology
Ø  Device Connect back to a Centralized Device
Ø  Used Ethernet Switch
Ø  If one link is fails, other links continue to work
Ø  The Centralize Device is a single Point of failure
Ø  Popular in Modern Network

  Hub and Spoke Topology:-

 Ø  Remote Site Connect Back to Central site
Ø  Minimize number of WAN Links
Ø  Can Result in Suboptimal Path

                Full Mesh Topology

Ø  Every Site connect to Every other Site
Ø  Not Scalable
Ø  Optimal Path

                Partial Mesh Topology

Ø  A Subset of Full topology
Ø  Links are Statically added based on traffic patterns



  1. thanks
    is this all types of networks?
