Integrity Check An integrity check is a validation process that determines whether a message, file, or dataset matches an expected state or reference. It is used to detect accidental corruption or malicious… Concept/Framework Inter Satellite Link An Inter Satellite Link is a communication path used for data exchange between satellites, enabling spacecraft to relay information directly in orbit. Hardware Inter-Domain Routing Inter-domain routing is the process of advertising and selecting network reachability information between separate autonomous systems or similar routing domains. It uses policy to decide which routes are accepted, exported,… Concept/Framework Interference Interference is any undesired electromagnetic signal or emission that reduces the performance of a receiver or sensing system. It may be caused by co-channel overlap, adjacent-channel leakage, harmonic content, intermodulation,… Concept/Framework Intermodulation Distortion Intermodulation Distortion is unwanted signal products created when nonlinear components mix multiple frequencies and generate additional spurious tones. Hardware Internet Routing Internet routing is the distributed routing process that advertises, exchanges, and selects reachability information across the internet. It is the mechanism that allows traffic to cross administrative boundaries and reach… Concept/Framework IS-IS IS-IS is an Interior Gateway Protocol that uses link-state information flooding to enable routers within a routing domain to build a shared topology map and compute shortest or best internal… Protocol Jitter Jitter is the variation in the timing of packet arrival or signal delivery relative to an expected cadence. It is a measure of timing instability in a transport path or… Concept/Framework Keepalive Interval Keepalive Interval is the time between periodic messages sent to confirm that a connection, peer, or service is still reachable. Protocol Key Management Key Management is the lifecycle process for generating, distributing, storing, rotating, and revoking cryptographic keys. It protects the use of encryption and authentication systems. Operations
