![]() ![]() 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 transmissionĮach 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 device’s peers to each other.įaster 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 increasesĮach 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.Īll 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 organization’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. What is Data Center Service Management (DCSM)?.What is the Federal Data Center Optimization Initiative (DCOI)?. ![]()
