MAC Address
The physical identifier of a network interface used mainly on the local network
View definitionMPLS
A label-switching technology used by carriers to transport and isolate traffic.
View definitionMSS
Maximum data size TCP carried in a segment.
View definitionMTU
The maximum size of a package that can be transmitted on a link without fragmentation.
View definitionMulticast Routing
Multicast routing delivers traffic from a source to multiple subscribed receivers using distribution trees rather than individual unicast copies.
View definitionNAT
Translation of network addresses used in particular to share a public IP address between several private devices
View definitionNAT64
A translation mechanism that lets IPv6 clients communicate with IPv4 servers.
View definitionNetFlow
A technology for exporting network flow statistics originally developed by Cisco.
View definitionNetwork Port
A logical number identifying a service or application on an IP address.
View definitionNTP
The protocol used to synchronize the time of computer equipment.
View definitionOSPF
A dynamic routing protocol used within an organization.
View definitionOSPF Area
An OSPF area groups routers and links to limit link-state flooding and organize routing information.
View definitionOSPF Cost
OSPF cost is a link metric used by the shortest-path calculation to select routes.
View definitionOSPF DR/BDR
An OSPF designated router and backup designated router reduce adjacency overhead on multiaccess networks.
View definitionOSPF Neighbor State
OSPF neighbor states track adjacency formation, from discovery through full database synchronization.
View definitionOSPF NSSA
An OSPF Not-So-Stubby Area permits selected external routes via Type 7 LSAs while restricting other external advertisements.
View definitionOSPF Stub Area
An OSPF stub area limits external route advertisements and commonly uses a default route from an area border router.
View definitionPAT
Form of NAT which differentiates several connections thanks to port numbers.
View definitionPIM Dense Mode
PIM Dense Mode initially floods multicast traffic and then prunes branches with no interested receivers.
View definitionPIM Sparse Mode
PIM Sparse Mode builds multicast distribution trees on demand, often using a rendezvous point.
View definitionPing
A simple network test to check if a destination is responding and to measure the return time
View definitionPoE
A technology that supplies electrical equipment directly through its Ethernet cable.
View definitionPolicy-Based Routing (PBR)
Policy-based routing selects packet forwarding paths using rules such as source address or service rather than destination alone.
