Moves, adds, and changes can be done without taking the network offline Many devices can transmit data at the same time, allowing for high amounts of traffic Highly reliable as there is no possible single point of failure Only some devices are connected to multiple devices which is more cost-effective and practical. Each device is connected to every other device in the network for a high level of redundancy. The non-hierarchal structure results in a lack of dependency on any single device or circuit. Data is transmitted by routing (sent the shortest distance) and flooding (sent to all devices). In a mesh topology, devices are interconnected with each device being directly connected to many others. Overall performance and bandwidth are limited by the technical specifications of the switch Requires more cabling, resources, and maintenance than some alternatives The switch is a potential single point of failure and can disable the entire network It is the most common network topology and is often used for Local Area Networks (LANs).Дevice failures are easy to identify, and they do not impact the rest of the networkДЄdding or removing devices is simple and can be done without downtimeД¬apable of sustaining a high-performance network All data travels from the source to the switch where it is directed to its destination. In a star topology, each device is connected to a central switch. The entire network needs to be taken offline to perform moves, adds, and changes No need for a network server to manage data transmissionД®ach device is a potential single point of failure unless redundancy is built in Low likelihood of packet collision due to unidirectional data flow If a device fails, the ring collapses by connecting that deviceвЂ™s peers to each other.ДЇaster than a bus topology while still easy to add devices An additional ring in the opposite direction is activated if a switch fails. A second connection is made between devices.

To provide redundancy and resiliency, there are variations of the ring topology such as: An electrical token travels around the ring that a device must have before it can transmit data. Data travels in one direction from the source until it reaches its destination. In a ring topology, a daisy chain of connected devices forms a closed loop. Troubleshooting is difficult in larger networks Performance decreases as devices are added or traffic increases The bus cable is a potential single point of failure If one device fails, the rest of the network is not impacted The bus branches off into multiple sections, resulting in more than two endpoints. All devices are connected by a single bus with two endpoints. Data is transmitted from the source in both directions until it reaches its destination. In a bus topology, all devices are connected to one central cable called a bus. The entire network needs to be taken offline to perform maintenance Network speed is reduced proportionately as the number of devices increasesД®ach device presents a potential single point of failure One of the easiest networks to add devices to A daisy chain forms a ring topology when it is configured as a closed loop.

In a daisy chain topology, all devices are connected in a series. If either device fails, the network fails In a point-to-point topology, two devices are connected by a single cable.ДЄll available bandwidth is dedicated to the two devices The most common network topologies, roughly in order of complexity, are: When designing and installing a network, data center professionals must consider their organizationвЂ™s goals, budget, and size to determine the best topology to implement. Networks can be organized in a variety of topologies that each have advantages and disadvantages. When represented visually in the form of network diagrams, they help data center professionals document and understand their network infrastructure.

Network topology is the physical and logical arrangement of the devices, connections, and data circuits in a network.
