Core Network

Classful IP Addressing Classful IP addressing is an IPv4 addressing scheme in which address ranges are divided into fixed classes with predetermined network and host boundaries. It was used in early internet design… Concept/Framework Classless Inter-Domain Routing Classless Inter-Domain Routing is an IP addressing and routing method that represents networks with variable-length prefixes rather than fixed address classes. It enables more efficient allocation and aggregation of routes. Concept/Framework Clock Synchronization Clock Synchronization is the process of aligning clocks across devices or systems so they share a common time reference or bounded offset. Operations Connection State Connection State is the stored information that describes an active or previously observed communication relationship between endpoints. Operations Control Plane Control Plane is the part of a network or system that makes decisions about how traffic should be handled or where resources should be directed. Concept/Framework Convergence Time Convergence time is the period required for a routing system to process changes, exchange information, and reach a stable and usable forwarding state. It is a measure of control-plane responsiveness. Concept/Framework Core Network Core Network is the central part of a communication network that connects aggregation, service, and transport functions, providing centralized connectivity and control. Concept/Framework Cross Domain Solution Satcom Cross Domain Solution Satcom is a controlled security mechanism that transfers data between satellite communication domains with policy enforcement and filtering. It mediates data crossing from one satcom security domain… Concept/Framework Data Diode Data Diode is a hardware or logical boundary that enforces unidirectional data flow between two networks or security domains, allowing data to leave one domain while preventing traffic from returning… Hardware Data Plane Data Plane is the part of a network or system that handles the actual movement or processing of traffic once a control decision has been made.
