Key Points Control method without output feedback correction Applied in contexts where the process is predictable enough that fixed input is acceptable Used in simple automation, timed operations, and systems where feedback is unavailable or unnecessary Simpler than feedback control…
Key Points Prioritizes selected traffic classes based on service requirements Manages bandwidth, delay, jitter, and loss behavior Used to support service differentiation when resources are constrained Applies in enterprise networks, carrier networks, industrial networks, and real-time communication systems Operates through…
Key Points Identity And Access Management combines security controls with system governance Processes and controls for identity verification and access authorization Used in cloud computing, enterprise IT, and regulated system contexts Includes identity creation, authentication, authorization, and lifecycle management Treats…
Key Points Process Variable is the measured value used by a control system It exists to represent the current state of the process relative to a target The process variable is compared with a setpoint to determine control action Used…
Key Points Uses path information in route advertisements Supports inter-domain routing decisions Helps prevent routing loops Foundation for BGP-like behavior Enables policy-based route acceptance and filtering Definition Path Vector Routing is a routing method in which route advertisements include path…
Key Points IBGP is a communication protocol for internal BGP routing sessions within a single autonomous system Used in service provider networks, enterprise routed networks, and large internal routing designs Supports route propagation and internal consistency without crossing administrative boundaries…
Key Points Network architecture separating control and forwarding functions Makes network behavior programmable, centralized, and adaptable to policy Deployed in data centers, telecom networks, cloud environments, and enterprise networking Places decision-making in a control layer that programs forwarding behavior of…
Key Points Process Gain is defined for network or system use Ratio or relationship between input change and output change Used in operational and control contexts Characterizes process sensitivity and supports control tuning Controller settings depend on how strongly the…
Key Points Policy Enforcement is defined for network or system use Application of defined rules or controls in operation Used in operational and architecture contexts Operates at access, routing, service, or application layers depending on the system Definition Policy Enforcement…
Key Points Source-routing method using ordered forwarding instructions Encodes path behavior as segments so routers can follow intended forwarding instructions Eliminates need for each hop to maintain separate complex path state Simplifies traffic steering and path control Used in service…
