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 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.
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.
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.
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 ...
The Metro Ring Protocol (MRP) is a Layer 2 resilience protocol developed by Foundry Networks and currently being delivered in products manufactured by Brocade Communications Systems and Hewlett Packard.
A graphic representation of a daisy chain A daisy garland, a chain of daisy flowers A series of devices connected in a daisy chain layout. In electrical and electronic engineering, a daisy chain is a wiring scheme in which multiple devices are wired together in sequence or in a ring, [1] similar to a garland of daisy flowers.
The most well-known examples are IBM Token Ring and ARCNET, but there were a range of others, including FDDI (Fiber Distributed Data Interface), which was popular in the early to mid 1990s. Token passing schemes degrade deterministically under load, which is a key reason why they were popular for industrial control LANs such as MAP ...
