What is ARP? – Address resolution in networks

What is ARP (Address Resolution Protocol)?

When computer information is sent in TCP/IP networks, it is first decompressed into individual data frames. In this way, you can transfer data of nearly unlimited size. The frames also contain the target system’s MAC address, without which a transmission would not be possible. If the physical address is not known, the sender must first be determined using the ARP Address Resolution Protocol. Here,...

MPLS:  What is Multiprotocol label switching?

MPLS: What’s behind the network technology

Speed and reliability play an important role for data transfer in networks. They reflect the quality of the connection, which is why providers do everything they can to guarantee the agreed services. A method primarily used in virtual private networks is the so-called multiprotocol label switching (MPLS).

What is Neighborhood Discovery Protocol(NDP)?

Neighbor Discovery Protocol (NDP) – what is it?

Network configurations today are done quickly. For those who do not rely on their own fixed settings for routers, computers, and more, the Internet Protocol family provides the appropriate set of automatic mechanisms to determine critical parameters, such as the default gateway, IP address, and MAC address.

Over 1,000 community members work on the Debian project, furthering the development of the collection. But how did Debian become so successful? And what makes this system software so interesting to...

Network protocol: Standards for data exchange

Network protocol: The basis of electronic data exchange

For computer systems to be able to communicate with each other and exchange information, they need common ground, just like humans must share a common language. But computers don’t rely on foreign language lessons, and instead only need the appropriate network protocol to successfully communicate. This provides guidelines and structures for the data transfer, and so plays a decisive role in the...
