What is the distributed data interface for the thread?

The

distributed data interface, also known as FDDI, is a network technology based on optical fibers. The FDDI net, which is usually organized in the topology of the ring, star or tree net, can cover many kilometers or kilometers. FDDI is often used in networks of university areas because of its relatively high speed and long distances. It is also used in some spines of the metropolitan network for the same reasons. FDDI was primarily designed to provide a faster and more reliable network backbone. Ethernet and 4/16 Mbps token ring based on 10 megabites per second (MBPS) and 4/16 Mbps were no longer sufficient for many networks. FDDI, on the other hand, can offer 100 Mbps data transfer via a secure optical fiber without interference. Its architecture with a double ring generally also provides the tolerance of redundancy and failures.

The interface fiber operation flows in the opposite directions on both circles. In a typical operation, the main ring bears all data while drThe fleeing ring remains available in the case of a hardware error. Individual nodes can be connected to both rings simultaneously or only to the main ring. The node connected to the main ring itself is connected via the concentrator. In this case, the concentrator can use a secondary ring to provide a path around the problem on the primary ring.

node connected to both rings of the network interface interface The thread interface may not be connected to the concentrator. The extension itself with the double circling allows an alternative path if part of the primary ring fails. However, this configuration can tolerate only one point of failure on the main ring. If more than one node is disconnected, the off or otherwise fails, the parts of the ring will not be able to communicate. The concentrators can be used with nodes connected to both rings to provide another layer of fault tolerance.

Some networks consist of spine distributionAné data interface of the distributed fiber along with the local Ethernet or Token Ring. This maintains the total costs by minimizing the amount of FDDI technology. If shorter distances are connected and interference is not a problem, the same network protocols can be implemented copper. This method, called distributed copper data interface, is very similar to FDDI, but uses copper instead of optical cables with optical fibers. FDDI networks can also be configured to trigger data in both directions, which double the permeability of losing errors.

The high costs and complexity of the distributed data interfaces for fiber are less popular from 90 years. For example, Ethernet, Gigabit Ethernet and Fibre Channel offer more speed at much lower costs. They also continue to work when the connected devices are turned off or removed from the network.
