Core Network

Feeder Link Feeder Link is the link between a user-facing access element and a gateway, hub, or network core segment that transports aggregated traffic into the larger network. Protocol Forwarding Plane Forwarding Plane is the part of a network device that moves packets or frames based on forwarding decisions. It is the operational path for traffic movement through the device. Software Gateway Gateway is a device, node, or service that connects two networks or protocol domains and often translates or routes traffic between them. It sits at a boundary between systems. Hardware Gateway Diversity Gateway Diversity is the use of multiple gateway paths, sites, or providers to reduce dependency on a single gateway point of failure. Concept/Framework High Availability High Availability is a design approach that aims to keep a system or service accessible and operational with minimal downtime through redundancy and failover patterns. Operations Holddown Timer Holddown Timer is a routing control mechanism that temporarily suppresses acceptance of route changes after a failure to reduce routing instability by holding a route in a suppressed state for… Operations Holdover Timing Holdover Timing is the ability of a system to continue providing acceptable timing when its external reference is temporarily unavailable. It maintains timing during reference loss. Operations Hub And Spoke Architecture Hub And Spoke Architecture is a network design in which endpoints connect through a central hub rather than directly to one another. It simplifies interconnection but centralizes dependency. Concept/Framework IBGP IBGP is the internal BGP session used to exchange routes within the same autonomous system. It distributes internal routing information across a domain. Protocol Inbound Reachability Inbound reachability is the property of a network or service being accessible from external sources through the appropriate routing and policy paths. It is a prerequisite for externally facing services… Concept/Framework
