Network topologies Flashcards
MPLS(Multiprotocol Label Switching)
capability to support multiple protocols on the same networt.
Its a WAN technology used by service providers to connected multiple sites.
Point to point
The point-to-point link is often used for organizations that need a direct link between two remote office buildings.
Point to multipoint (PtMP)
wireless connection designed to link multiple wired networks.
Signals in point-to-multipoint networks travel from a central node such as a base station of a cellular system, an access point of a WLAN, or a satellite.
Function: to interconnect multiple locations,
Ring
Ring networks are most commonly wired in a star configuration.
In a token ring network, a multistation access unit (MSAU) is equivalent to a hub or switch on an Ethernet network. The MSAU internally performs the token circulation.
Star
most popular physical LAN topology in use today
An Ethernet switch at the center of the star and unshielded twisted-pair cable (UTP) used to connect from the switch ports to clients.
Mesh
The wired mesh topology incorporates a unique network design in which each computer on the network connects to every other computer.
The purpose of the mesh design is to provide a high level of redundancy. If one network cable fails, the data always has an alternative path to get to its destination
The number of required WAN connections can be calculated with the formula w = n * (n-1) / 2, where w = the number of WAN links and n = the number of sites
Bus
A bus topology uses a trunk or backbone to connect all the computers on the network, Systems connect to this backbone using Tconnectors or taps (known as a vampire tap, if you must pierce the wire). To avoid signal reflection, a physical bus topology requires that each end of the physical bus be terminated, with one end also being grounded.
Peer-to-peer
Peer-to-peer networks allow interconnected devices (for example, PCs) to share their resources with one another. Those resources could be, for example, files or printers.
Client-server
Client-server networks are commonly used by businesses. Because resources are located on one or more servers.
Hybrid
As you might expect, topology designs are not black-and-white. Many topologies found in large networking environments are a hybrid of physical topologies. An example of a hybrid topology is the star bus—a combination of the star topology and the bus topology.
