WAN Technologies and Switching Methods

Classifying communication networks based on how nodes exchange information.

A network that spans a wide geographical area, connecting different locations together.

Moving data through a series of intermediate steps or segments, making efficient use of transmission resources.

A type of switching where a dedicated path is established between the sender and receiver for the entire duration of communication.

A type of switching where data is divided into packets, sent independently, and reassembled at the destination.

A type of packet-switching network that establishes a virtual connection between sender and receiver before data transmission. This connection remains active for the duration of the session, ensuring data is delivered in order.

A type of connection-oriented service that uses a temporary virtual connection, established specifically for each session. When the session ends, the connection is closed.

A type of connection-oriented service that uses a permanent virtual connection, always active between sender and receiver. Data can be transmitted without needing to establish a new connection each time.

An approach to packet switching where each packet is treated independently, with no established connection between sender and receiver. Packets are routed individually through the network, possibly taking different paths.

An approach to packet switching where a virtual connection is established between sender and receiver before data transmission. This connection ensures packets are delivered in the correct order.

A type of packet-switching network that allows multiple devices to share a single physical link. Packets are queued and transmitted as fast as possible, improving line efficiency.

A type of packet-switching network that uses a fixed-size data unit called a cell. These cells are then routed through the network using a dedicated switching technique.

A high-speed network technology that uses fixed-size cells for data transmission.

A network that uses ATM technology. It allows for high-speed transmission of various types of data, making it suitable for demanding applications.

A major limitation of ATM networks. Businesses are hesitant to invest in expensive ATM equipment without widespread carrier support, while carriers are reluctant to invest without sufficient demand.

The next generation of ISDN (Integrated Services Digital Network). It offers a comprehensive communication platform for various types of data, voice, and video.

BISDN categorizes services into interactive services, like real-time communication, and distribution services, such as video streaming.

A type of network service where information is delivered or broadcast to recipients who can't control the transmission except by choosing not to receive it.

A type of network service where transactions occur directly between two parties, like video conferencing or messaging.

A type of networking technology that uses time division multiplexing (TDM) to interleave multiple transmissions onto a single signal.

A higher-speed networking technology that uses Asynchronous Transfer Mode (ATM) with packet switching and small data cells.

The process of deciding and selecting the best route for data packets in a network.

A packet switching technique using fixed-size units (53 bytes) called cells. It's designed for high-speed transmission of various data types (data, voice, video).

A data link layer technology that uses permanent virtual circuits for fast packet switching. Frames (data packets) up to 4 KB are transmitted at high speeds over dedicated paths.

Independent data units sent in packet switching networks. They are treated individually and may take different routes.

Network technology that focuses on sending data in packets, without establishing a dedicated connection. Packets may follow different paths and may arrive out of order.

A network technology that uses fixed-size packets (cells) for high-speed transmission. It's designed for simultaneous transport of data, voice, and video.

A mechanism used in networks to manage the flow of data. It can involve slowing down transmission speeds or discarding low-priority packets to prevent congestion.

A routing algorithm computes the optimal route for data traffic in a network. It considers factors like network topology, traffic load, and link quality to choose the best path.

The process by which all routers in a network agree on the optimal routes to reach destination networks.

The speed at which routers can agree on the best route to reach a destination. A slower convergence can lead to traffic loops or network outages.

A table stored within a router that contains a list of known destinations and the next hop to reach them.

A simple routing approach where the routing table only contains the next hop to reach a destination.

A routing technique that reduces routing table size by grouping hosts on the same physical network under a single entry.

The process of moving packets from one network interface to another. It's the immediate action of forwarding data.

A routing algorithm that doesn't adapt to network changes like traffic or topology alterations.
