Software-Defined Networking

Computer Network

A collection of interconnected computing devices that share resources and communicate using standardised protocols.

TCP/IP

Transmission Control Protocol/Internet Protocol — the fundamental communication protocol suite powering the internet.

HTTP

Hypertext Transfer Protocol — the application-layer protocol for transmitting hypermedia documents on the World Wide Web.

HTTPS

HTTP Secure — an encrypted version of HTTP using TLS for secure communication over the internet.

DNS

Domain Name System — the hierarchical system that translates human-readable domain names into numerical IP addresses.

IP Address

A unique numerical label assigned to each device connected to a computer network for identification and routing.

IPv6

The most recent version of the Internet Protocol, providing a vastly larger address space than IPv4.

Subnet

A logical subdivision of an IP network that improves security and performance by segmenting traffic.

Wi-Fi 6

The sixth generation of Wi-Fi technology offering improved speed, capacity, and performance in dense environments.

Network Latency

The time delay between sending and receiving data across a network, measured in milliseconds.

Bandwidth

The maximum rate of data transfer across a network path, typically measured in bits per second.

Throughput

The actual rate of successful data transfer across a network in a given time period.

Software-Defined Wide Area Network — a virtualised network architecture that enables centralised management of geographically distributed networks.

A protocol that determines the optimal path for data packets to travel across interconnected networks.

Virtual Local Area Network — a logical grouping of network devices that communicate as if on the same physical network.

Virtual Private Network — a technology creating a secure, encrypted connection over a less secure network like the internet.

An intermediary server that forwards requests between clients and other servers, providing security and caching.

The arrangement of elements such as nodes, links, and devices in a computer network.

Border Gateway Protocol — the routing protocol that manages how packets are routed across the internet between autonomous systems.

A server that sits in front of web servers and forwards client requests to the appropriate backend server.
