IGMP snooping
IGMP snooping: eavesdropping for multicast traffic
  • Know-how

If a system in IP networks is to send data packets to different target hosts as efficiently as possible, an IP multicasting connection is the perfect solution. When it comes to multipoint transmission, the data packets are able to reach all interested parties thanks to various protocols such as GMP, for example. Switches and internet routers can also use the communication protocol for IGMP...

SNTP: simple network time protocol
Simple network time protocol: the stripped-back protocol for time synchronization
  • Know-how

An exact system time on a computer is especially important when devices need to exchange data. Cross-system processes quickly come to a standstill if the generated time stamps are very different from the time that applies to the system. Synchronization methods that keep the clocks of the individual network participants in sync are utterly indispensable. One of the simplest methods to achieve time...

IGMP - Internet Group Management Protocol
IGMP: what is behind the Internet Group Management Protocol
  • Know-how

Using multicast connections, data streams can be transferred to a large number of clients easily and in such a way that saves resources – provided that the accessing systems are part of the same multicast group. In IPv4 networks, the organization and management of these groups is based on the Internet Group Management Protocol (IGMP), which was published as early as 1989. What exactly this...
