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.
A network's logical topology is not necessarily the same as its physical topology. For example, the original twisted pair Ethernet using repeater hubs was a logical bus topology carried on a physical star topology. Token Ring is a logical ring topology, but is wired as a physical star from the media access unit.
Visualization of an all-to-all algorithm in a ring topology. Visualization of an all-to-all algorithm in a mesh topology. We consider a single-ported machine. The way the data is routed through the network depends on its underlying topology. We take a look at all-to-all algorithms for common network topologies.
Mesh topology may be contrasted with conventional star/tree local network topologies in which the bridges/switches are directly linked to only a small subset of other bridges/switches, and the links between these infrastructure neighbours are hierarchical. While star-and-tree topologies are very well established, highly standardized and vendor ...
Switching, multiplexing, and grooming of traffic in an OEO device. Optical mesh networks refer to transport networks that are built directly off the mesh-like fiber infrastructure deployed in metropolitan, regional, national, or international (e.g., trans-oceanic) areas by deploying optical transport equipment that is capable of switching traffic (at the wavelength or sub-wavelength level ...
HSR is typically used in a ring topology or in another mesh topology. Nodes with single attachment (such as a printer) are attached through a RedBox (Redundancy Box). Redundant connections to other networks are possible, especially to a Parallel Redundancy Protocol (PRP) network.
Token Ring is a physical and data link layer computer networking technology used to build local area networks. It was introduced by IBM in 1984, and standardized in 1989 as IEEE 802.5. It uses a special three-byte frame called a token that is passed around a logical ring of workstations or servers.
The animation illustrates how a two dimension torus is generated from a rectangle by connecting its two pairs of opposite edges. At one dimension, a torus topology is equivalent to a ring interconnect network, in the shape of a circle. At two dimensions, it becomes equivalent to a two dimension mesh, but with extra connection at the edge nodes.
