A ring network is a network topology in which each node connects to exactly two other nodes, forming a single continuous pathway for signals through each node – a ring. Data travels from node to node, with each node along the way handling every packet.
Ring network topology. A ring topology is a daisy chain in a closed loop. Data travels around the ring in one direction. When one node sends data to another, the data passes through each intermediate node on the ring until it reaches its destination. The intermediate nodes repeat (retransmit) the data to keep the signal strong. [5]
A ring link is bounded by two adjacent Ethernet Ring Nodes, and a port for a ring link is called a ring port. The minimum number of Ethernet Ring Nodes in an Ethernet Ring is three. [1] The fundamentals of this ring protection switching architecture are: The principle of loop avoidance.
During normal operation, the network works in the Ring-Closed status (Figure 1). In this status, one of the MRM ring ports is blocked, while the other is forwarding. Conversely, both ring ports of all MRCs are forwarding. Loops are avoided because the physical ring topology is reduced to a logical line topology.
Bisection of linear array network. For ring topology with n nodes two links should be broken to bisect the network, so bisection bandwidth becomes bandwidth of two links. Bisection of a ring network. For tree topology with n nodes can be bisected at the root by breaking one link, so bisection bandwidth is one link bandwidth. Bisection of a tree ...
An IBM 8228 Multistation Access Unit with accompanying Setup Aid Data flow though a 3-station Token Ring network built using a single MAU. A media access unit (MAU), also known as a multistation access unit (MAU or MSAU), is a device to attach multiple network stations in a ring topology when the cabling is done in a star topology as a Token Ring network, internally wired to connect the ...
Layout of a grid low-voltage network. A grid network is a computer network consisting of a number of computer systems connected in a grid topology. In a regular grid topology, each node in the network is connected with two neighbors along one or more dimensions. If the network is one-dimensional, and the chain of nodes is connected to form a ...
The physical layout of the nodes in a network may not necessarily reflect the network topology. As an example, with FDDI, the network topology is a ring, but the physical topology is often a star, because all neighboring connections can be routed via a central physical location. Physical layout is not completely irrelevant, however, as common ...
