Core Network

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 Path Diversity Path diversity is the design condition in which a network has more than one independent path available between endpoints or service domains. It is used to improve resilience, traffic distribution,… Concept/Framework Policy Based Routing Policy Based Routing is routing that uses rules or policies beyond the standard destination-based routing table to decide how traffic should be forwarded. Protocol Prefix A prefix is a contiguous block of IP addresses identified by a base address and a prefix length. In routing, it is the unit that systems advertise, aggregate, filter, and… Concept/Framework Quality Of Service Quality Of Service is the degree to which a service or network meets defined performance characteristics such as delay, loss, and bandwidth. Operations Redundancy Scheme A Redundancy Scheme is a design approach that duplicates or backs up components so a system can keep operating after a failure. It improves availability and fault tolerance. Operations
