Bus Topology

Noun
|
Sounds like: "bus to-pol-o-gy"

Bus topology, also known as line topology, is a type of network topology in which all devices in the network are connected by one central RJ-45 network cable or coaxial cable. The single cable, where all data is transmitted between devices, is referred to as the bus, backbone, or trunk.

There are two types of bus topologies:

  • Linear bus topology. All devices are connected to a single cable with two end points.
  • Distributed bus topology. All devices are connected to a single cable that branches off into multiple sections, resulting in more than two end points.

Advantages of Bus Topology

  • Works efficiently for small networks
  • Easy and cost-effective to install and add or remove devices
  • Doesn’t require as much cabling as alternative topologies
  • If one device fails, other devices are not impacted

Disadvantages of Bus Topology

  • If the cable is damaged, the entire network will fail or be split
  • Difficult to troubleshoot problems
  • Very slow and not ideal for larger networks
  • Requires terminators at both ends of the cable to prevent bouncing signals that cause interference
  • Adding more devices and more network traffic decreases the entire network’s performance
  • Low security due to all devices receiving the same signal from the source

Network Documentation with DCIM Software

Network topology diagrams are used to visually represent a network’s devices and connections, allowing you to picture how devices are devices communicate with each other. However, maintaining network topology diagrams are a manual process that is time-consuming and error-prone.

With Data Center Infrastructure Management (DCIM) software, you can visualize all your network and data circuits in 3D, document and understand how your assets are connected down to the port level, and ensure that you always have the most accurate information. DCIM software enables you to improve uptime, optimize capacity utilization, increase people productivity, and simplify validation.

WORD OF THE DAY:

Data Center Redundancy
Data center redundancy is a system design where a component is supplied in excess to ensure continued uptime in the event of a component failure.
