ring topology การใช้

• A ring topology is a bus topology in a closed loop.
• Some Industrial Ethernets use a ring topology to avoid collisions and provide deterministic performance.
• The ring topology best facilitates this requirement.
• Fiber optic cables connect the headend or hub to optical nodes in a ring topology.
• The three sites are connected via 10 Gbit / s connections in a ring topology.
• Loops are avoided because the physical ring topology is reduced to a logical stub topology.
• All recent systems have used fiber optic transmission, and a self-healing ring topology.
• This allows spatial reuse for frame transmission to / from MAC address not present in the ring topology.
• Star and ring topologies are not recommended because of signal reflections or excessively low or high termination impedance.
• Note that SNCP does not assume a ring topology, and can also be used in mesh topologies.
• This protocol is robust enough to work for unidirectional failure and multiple link failure scenarios in a ring topology.
• Token ring is a logical ring topology, but is wired as a physical star from the media access unit.
• While IBM's token ring is a logical ring topology, it is physically set up in star topology.
• HSR originally meant " High-availability Seamless Ring ", but HSR is not limited to a simple ring topology.
• In a network configured in ring topology, the ring can be temporarily broken at any point to also attach a device.
• In 1974 Wilkes encountered a Swiss data network ( at Hasler AG ) that used a ring topology to allocate time on the network.
• HSR is typically used in a ring topology, however redundant connections to other networks are possible ( such as a mesh topology ).
• This is similar in some ways to a grid network, where a linear or ring topology is used to connect systems in multiple directions.
• One option being considered is the ring topology, which consists of various sized ring networks being integrated within each other to connect the cores.
• In its first phase, ACOnet set up a private X . 25 network, which connected the universities in Linz in a ring topology.
