Why does this matter operationally?
Scalability
The ability of a connectivity architecture to accommodate growth in users, devices, data volume, or geographic coverage without requiring fundamental redesign. Scalable systems expand incrementally and maintain performance characteristics as load increases.

ROADM
Optical network equipment that adds, drops, or passes through individual DWDM wavelength channels at a network node under remote software control, enabling wavelength routing reconfiguration without manual fiber patching.
Hardware
Roaming
The commercial and technical arrangement letting a subscriber use a mobile network operated by a different provider than their own, governed by an inter-operator agreement covering billing and technical interconnection,…
Concept/Framework
Route Advertisement
Route advertisement is the process by which a routing device or system announces routes or prefixes to one or more peers. It is how reachability information spreads across a routing…
Protocol
Route Poisoning
Route Poisoning is a routing technique that advertises a failed route with an invalid metric so routers treat it as unreachable. It helps prevent loops and speed convergence.
Protocol
Route Reflection
Route Reflection is a BGP technique that allows one router to advertise routes to other routers within the same routing domain, reducing the need for full-mesh peering among internal BGP…
Protocol
Route Summarization
Route Summarization is the aggregation of multiple specific routes into a broader prefix that represents the same destination space at a higher level, reducing routing table size and protocol overhead.
Operations
Routing
Routing is the network function that computes and maintains paths between sources and destinations. It uses topology, policy, and metrics to choose one or more next hops for traffic.
Concept/Framework
Routing Metric
A routing metric is a numeric or rule-based measure used by a routing system to evaluate and compare paths. It helps determine which route should be preferred when more than…
Concept/Framework
Routing Policy
Routing policy is the set of administrative rules that govern how routing information is processed, filtered, modified, and selected. It defines which paths are preferred and which advertisements are permitted.
Concept/Framework
Routing Protocol
A routing protocol is a protocol used by network devices to advertise, learn, and maintain reachability and path metrics. The information it exchanges is used to construct routing tables and…
