Why does this matter operationally?
Cost Efficiency
The discipline of delivering required connectivity performance at sustainable operational and capital cost. Cost efficiency in connectivity involves trade-offs between link capacity, redundancy, technology choice, and managed service dependency.

Redundancy Scheme
A Redundancy Scheme is a design approach that duplicates or backs up components so a system can keep operating after a failure. It improves availability and fault tolerance.
Operations
Resilience
Resilience is the ability of a system to withstand disruption, recover from faults, and adapt to changing conditions while maintaining acceptable operation.
Operations
Retransmission
Retransmission is the sending of data again after a loss or failed delivery attempt. It is a reliability mechanism used when initial transmission is not successful.
Protocol
Return Link
Return Link is the communication path carrying traffic from the user or remote side back toward the network or ground side.
Protocol
RFID
A short-range identification technology in which a reader energizes and queries a nearby tag to retrieve a stored identifier, using passive tags that harvest all operating power from the reader's…
Hardware
RIP
RIP is a distance-vector routing protocol that shares routing information with neighboring routers. It uses hop count as its main metric and is common in legacy networks.
Protocol
ROADM
Optical network equipment that adds, drops, or passes through individual DWDM wavelength channels at a network node under remote software control, enabling wavelength routing reconfiguration without manual fiber patching.
Hardware
SD-WAN
SD-WAN is a network architecture that applies centralized policy to traffic flows across multiple wide area transport links. It typically uses branch edge devices, overlay tunnels, telemetry, and orchestration software…
Service Model
Shared Access Terminal
Shared Access Terminal is a terminal that provides network access to multiple users, devices, or services through a common access point.
Hardware
Shortest Path First
Shortest Path First is a routing approach that selects the shortest or lowest-cost route through a network graph by computing the minimum-cost path from available topology and metric information.
