Multi-Protocol Label Switching (MPLS) defines a mechanism for packet forwarding in network routers. It was originally developed to provide faster packet forwarding than traditional IP routing, although improvements in router hardware have reduced the importance [...]
Short for Multiprotocol Label Switching, an IETF initiative that integrates Layer 2 information about network links (bandwidth, latency, utilization) into Layer 3 (IP) within a particular autonomous system–or ISP–in order to simplify and improve IP-packet exchange. MPLS gives network operators a great deal of flexibility to divert and route traffic around link failures, congestion, and [...]

Definition: The MTU is a limit, expressed in bytes, on the size of data sent over a network. It is the maximum size of a single unit (e.g., an Ethernet frame) of digital communications.
MTU sizes are properties of physical network interfaces. The MTU for Ethernet, for instance, is 1500 bytes. Some types of networks (like [...]
Definition: Multihoming is the configuration of multiple network interfaces or IP addresses on a single computer. Multihoming is intended to increase the reliability of network applications but it does not necessarily improve their performance.In traditional multihoming, you install a second hardware network adapter on a computer that normally possesses only one. Then, you configure both [...]
When I first started studying for my CCNA years ago, one of the (many) things that confused me was ARP. Or rather, what ARP did as opposed to Reverse ARP, Inverse ARP, and Proxy ARP! One book would mention ARP without mentioning the other variations, one would mention RARP but not Proxy ARP, and so [...]
