Local Area Network (LAN)

Local Area Network (LAN) A local-area network (LAN) is a computer network that spans a relatively small area. Most often, a LAN is confined to a single room, building or group of buildings, however, one LAN can be connected to other LANs over any distance via telephone lines and radio waves. A system of LANs connected in this way is called a wide-area network (WAN). The difference between a LAN and WAN is that the wide-area network spans a relatively large geographical area. Typically, a...

Ingress Filtering

Ingress Filtering Ingress filtering is a method used by enterprises and internet service providers (ISPs) to prevent suspicious traffic from entering a network. When configured on an edge device such as a router or firewall, ingress filtering examines all inbound packets and then permits or denies entry to the network based on information in the packet header. It is a form of packet filtering. Ingress traffic filtering is one of the first lines of defense in a network security strategy. It i...

Converged Network Adapter CNA

Converged Network Adapter CNA Converged Network Adapter CNA: A converged network adapter (CNA) is a single network interface card (NIC) that contains both a Fibre Channel (FC) host bus adapter (HBA) and a TCP/IP Ethernet NIC. It connects servers to FC-based storage area networks (SANs) and Ethernet-based local area networks (LANs). The CNA connects to the server via a PCI Express (PCIe) interface. The server sends both FC SAN and LAN and traffic to an Ethernet port on a converged switch ...
