Core Network

Network Function Virtualization Network Function Virtualization is the implementation of network functions in software on general-purpose compute rather than dedicated purpose-built appliances. Software Network Resilience The broader capability of a network to maintain acceptable service continuity despite failures, disruptions, or adverse conditions, built from contributing mechanisms including redundancy, mesh topology, and fault management practice, and… Concept/Framework Network Segment A network segment is a portion of a larger network separated for forwarding, security, management, or operational purposes. It can be defined by switching, routing, policy, or physical separation. Concept/Framework Network Slicing Network Slicing is the creation of logically separated network instances over shared physical infrastructure to support different service requirements. Service Model Network Telemetry Network Telemetry is the collection and export of operational data from network devices and services for monitoring and analysis. Operations OSI Model OSI Model is a seven-layer conceptual framework that describes how network communication functions are organized from physical transmission to application services. Concept/Framework OSPF OSPF is a link-state interior gateway routing protocol used to exchange routing information within an autonomous system. It builds a topology view and computes shortest paths. Protocol OSPFv3 OSPFv3 is the IPv6 version of the OSPF link-state routing protocol used to exchange routing information within an autonomous system. It supports IPv6 routing domains. Protocol Packet Capture Packet Capture is the recording of network packets for analysis, troubleshooting, security review, or protocol inspection. It preserves traffic for examination. Operations Path Congestion Path congestion is the state in which a network path experiences traffic demand that approaches or exceeds its effective capacity, resulting in degraded performance. It is a path-level performance condition. Concept/Framework
