[1Day-1CS] Network Topology

Network Topology

How the nodes and links are arranged and how they are connected.

Tree topology

Hierarchical topology, a network organization laid out in the form of a tree.

• Easy to add and delete nodes

• Concentration of traffic on a particular node affects subordinate nodes

Bus Topology

Connecting multiple nodes to one centralized communication line

• Used for local area networks

• Low installation cost, high reliability, and easy to add and remove nodes to the centralized communication line

• Spoofing issues exist

Spoofing: to another host on the LAN that is not involved in the transmission. paralyzing or tricking a switch's ability to prevent the packet from going to treating a packet as if it were coming from a specific node.

Star topology

A network configuration where everyone is connected to a centrally located node.

• Easy to add nodes or detect errors

• Packets are less likely to collide

• Entire network is unavailable in the event of a central node failure

• High installation cost

Ring Topology

Moving data from node to node, processing packets through a ring-shaped path

• Little loss on the network as the number of nodes increases

• Less likely to crash and easier to detect node failures

• Difficult to change network configuration

• Failure affects the entire network

Mesh topology

Mesh topology, a reticulated connection structure

• Multiple paths exist to keep the network up and running if one terminal fails

• Possibility to distribute traffic

• Difficult to add nodes and expensive to build and operate
