Key Points Operates between autonomous systems Used for inter-domain routing Supports internet-scale route exchange Relies on policy as well as reachability Enables policy-based route control across administrative boundaries Used by service providers, enterprises with external connectivity, and networks that exchange…
Key Points Identifies a network interface logically Used for packet forwarding and reachability Exists in IPv4 and IPv6 forms Supports routing across interconnected networks Definition An IP Address is a logical address assigned to a network interface in an IP…
Key Points One-to-many-to-selected-receivers model Used in streaming and network distribution More efficient than multiple unicast copies Requires group membership or subscription Differs from broadcast by limiting to subscribed receivers only Differs from unicast by eliminating per-receiver sender replication Definition Multicast…
Key Points Describes responsive scaling behavior Common in cloud and distributed systems Helps match capacity to workload Related to automation and resource management Enables systems to adapt without permanent overprovisioning Definition Elasticity is the ability of a system to expand…
Key Points Stateful Inspection evaluates traffic based on connection or session context rather than isolated packets Used in firewalls, gateways, and network security appliances Improves control by understanding whether traffic belongs to an allowed relationship Operates at the Transport layer…
Key Points Covers higher microwave frequencies enabling greater bandwidth capacity Used in satellite communications, earth stations, and fixed wireless links Supports wider channel bandwidths and more compact antenna designs Weather sensitive, particularly susceptible to rain fade and atmospheric absorption Requires…
Key Points Operates as an internal routing protocol within a single autonomous system Supports link-state path computation using topology flooding Used in service provider backbones, large enterprise networks, and large routed infrastructures Provides route convergence and topology-aware forwarding within the…
Key Points Defines infrastructure in version-controlled files Enables repeatable provisioning and change management Reduces manual configuration drift Used in cloud and platform operations Treats infrastructure definitions as code artifacts subject to version control and review Definition Infrastructure As Code is…
Key Points Control Plane is defined for network or system use Decision-making plane that controls traffic handling or resource direction Used across network and system environments Operates separately from the forwarding or execution plane Definition Control Plane is the part…
Key Points Provides multiple paths between nodes Improves resilience and path diversity Used in network and wireless design Can be partial or full mesh Supports alternate routes and flexible communication paths Definition Mesh Topology is a network structure in which…
