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 Interior Gateway Protocol An Interior Gateway Protocol is a routing protocol used to exchange reachability information within a single network domain. It helps routers choose internal paths and converge on a shared view… Protocol 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 IP Address An IP Address is a logical address assigned to a network interface in an IP network. It is used for packet routing and reachability between hosts. Protocol 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 Latency Latency is the time delay between a source event and a destination response or arrival. It describes how long data or a signal takes to traverse a path. Operations Leaking Transit Leaking Transit is the unintended propagation of transit routes or traffic outside the boundaries where they are expected, representing a routing and policy failure. Operations Link State Routing Link State Routing is a routing method in which routers exchange and flood link-state advertisements to build a shared network topology map, then independently compute optimal paths using shortest-path algorithms. Protocol Load Balancing Load Balancing is the distribution of traffic or workload across multiple resources so no single resource becomes overloaded. Software
