Key Points Congestion Window is a sender-side limit on in-flight data under congestion control It prevents overwhelming the network by limiting outstanding data The congestion window adjusts with network feedback to balance throughput and fairness Used in TCP and other…
Key Points Coding Rate is the ratio of payload bits to total encoded bits Indicates the proportion of transmission devoted to redundancy Used across network and system environments Balances robustness against usable throughput Critical design parameter in error-control systems Definition…
Key Points Protects confidentiality of information Depends on cryptographic algorithms and keys Used in storage, transit, and identity systems Core control in modern security architectures Must be paired with key management and access control Operates across enterprise IT, cloud services,…
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 Used for integrity checking Common in communication and storage systems Detects corruption or alteration Often paired with retransmission or validation Definition Checksum is a calculated value used to verify the integrity of data by detecting whether it has…
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…
Key Points Phase Alignment is the adjustment of phase relationship between signals or clocks Used across network and system environments to support coherent transmission Critical in radio systems, clocks, signal processing, and industrial synchronization Requires measurement of relative phase difference…
Key Points Reduces visibility of traffic characteristics Can support security or operational discretion May use padding, shaping, or routing behavior Traffic metadata can reveal operational intent even when payload content is protected Definition Traffic Concealment is the practice of hiding…
Key Points Packet Capture is defined for network or system use Recording packets for later inspection and analysis Used in operational and architecture contexts Supports debugging, traffic analysis, and security investigation Gives operators direct evidence of what traversed the network…
Key Points Refers to route or traffic leakage outside intended policy boundaries Occurs in inter-domain or policy-based routing contexts Can create reachability or policy problems Relevant in provider and enterprise network design Used in BGP and other inter-domain routing environments…
