Key Points Port Exhaustion is the depletion of available ports for new transport sessions Operates across network and system environments Prevents new session creation even when other network capacity remains Occurs in NAT gateways, proxies, and high-connection networks Definition Port…
Key Points Measures delivered data rate Can differ from nominal bandwidth Affected by overhead and congestion Used in network and system performance analysis Accounts for protocol overhead, congestion, retries, and other losses Definition Throughput is the actual amount of data…
Key Points Distributes shared capacity among users, flows, or services Used in access and transport systems Can be static, scheduled, or dynamic Supports fairness and service prioritization Managed through admission control, shaping, scheduling, or capacity grants Definition Bandwidth Allocation is…
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 Reduces overload in shared networks Used in transport and routing systems Supports stable throughput and fairness Often works with retransmission and flow control Adjusts sending rates, manages queues, or influences traffic patterns to maintain useful throughput Prevents excessive…
Key Points Maintains operation after faults instead of immediate shutdown May continue in degraded mode with reduced capability Common in safety-critical and control applications Depends on redundancy, fallback modes, and fault isolation Preferred or required in industrial systems and resilient…
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 Traffic Engineering involves deliberate planning and control of traffic flow to meet network objectives Used to balance load, protect services, and control latency across network environments Operates through metrics, policy, or explicit path selection to steer flows intentionally…
Key Points Supports vessels, offshore platforms, and marine operations Combines satellite, cellular, radio-based, and onboard networking systems Maintains operational and crew communications across changing coverage areas Critical for shipping, offshore energy, port logistics, and passenger services Subject to environmental constraints…
Key Points Describes layered internet protocol behavior Includes transport and internet functions Foundation of IP networking Used in nearly all modern networks Organizes communication into layers so each layer handles its own part of the process Definition TCP-IP Stack is…
