Computer Network Topology

Defines a map of the network topology. Network topology can be broadly divided into two kinds of physical topology and logical topology. Discussing the various topologies, but in this thesis the author initiative to design a network using a star topology.
physical topology
Physical topology defines how the composition of the laying of the nodes on the network. There are several types of physical topologies, among others:

 Bus Topology
Is a network architecture in which a set of clients connected to the main cable (baonckbe) is called buses. Bus network is the simplest way to connect multiple clients, but the most common problem encountered is when two client will send data at the same time on the same bus.
Bus Topology Advantages
1. Save cables.
2. Simple wiring layouts.
3. Network development or adding new workstations can be done easily without disturbing other workstations.
Bus Topology loss
1. Fault detection and isolation is very small.
2. Density of traffic on the main line.
3. The drawback of this topology is that if there is interference in the cable along the center of the whole network will be impaired.
4. Required repeater for long distance.

 Star Topology
Is one of the most commonly used topologies. Star network consists of a main switch serving as a router that transmits data.

Star Topology Advantages
1. Most flexible.
2. Installation / change station is very easy and does not interfere with other parts of the network.
3. Centralized control.
4. Ease of detection and fault isolation / damage tissue management.
Shortage of Star Topology
1. Boros cable.
2. Need special handling.
3. Centralized control (HUB) so the critical element.

 Ring Topology
Is a network topology in which each node is connected to two other nodes, so it will form a ring. Ring topology is less efficient when compared to the star topology as the topology of data to go through a lot of points before the data reaches the destination.
Ring Topology Advantages
• Not the collision or the collision of data transmission such as the bus topology, since only one node can transmit data at a time, the low level of network complexity (simple), also if there is a disruption or damage to the central flow of traffic can be passed in the other direction in systems.
Ring Topology shortage
• In each node in the network will always follow and manage the information that is passed in the network, so that if there is interference in a node then the entire network will be disrupted.

 Mesh Topology
Mesh topology is a way to download the route data, voice and instructions between nodes. Enabling continuous connection and reconfigure around broken or blocked paths by hopping from one node to another node until it reaches the destination. Mesh topology is a subclass of mobile ad hoc networking (MANET).
Mesh Topology Advantages
• If there is a broken link then a statin can find another link.
Disadvantages Mesh Topology
• Not practical for wearing a lot of wires.
• The cost is high enough to be implemented.

  1. I so remember the days SMP with lessons on such topologies heheheh,,,,,,
