Why does this matter operationally?
Performance
The measurable behaviour of a connectivity system under real operating conditions, including throughput, latency, jitter, and packet loss. Performance determines whether applications and control systems receive data at the speed and consistency their operations require.

Storm Avoidance Data Link
Storm Avoidance Data Link is the communications link used to transmit storm-avoidance advisories, forecasts, or route changes to Maritime operators. It supports safety-aware navigation and enables timely operational response to…
Protocol
Subnet
A subnet is a portion of a network’s address space that has been divided into a smaller routable segment. It is used to group hosts, control traffic, and simplify administration.
Concept/Framework
Supervisory Control
Supervisory Control is a control layer that monitors processes and issues high-level commands rather than directly regulating low-level behavior continuously. It oversees the process through coordination and command rather than…
Operations
Supervisory Control System
Supervisory Control System is a higher-level control system that monitors processes and coordinates lower-level controllers and field devices. It oversees local control rather than replacing it.
Operations
Surveillance Relay
Surveillance Relay is a relay link or node that forwards surveillance data or extends surveillance communications coverage.
Software
Switching
Switching is the process of forwarding frames, packets, or flows across a network according to addressing or forwarding rules. It is used to connect endpoints and segments inside a network…
Concept/Framework
Synchronization
The practice of aligning multiple systems, devices, or measurements to a common, precise time reference, enabling events or data captured at different physical locations to be directly compared, sequenced, or…
Concept/Framework
Synchronous Ethernet
SyncE is a mechanism for recovering and distributing a common frequency reference over Ethernet so downstream devices can lock to a stable transport clock.
Protocol
Synchronous Transmission
Synchronous Transmission is transmission that uses a shared timing reference so sender and receiver remain aligned during communication. It depends on coordinated timing.
