The two Ethernet interfaces of a node use the same MAC address. This is allowed since the two LANs have no connection. Therefore, PRP is a layer 2 redundancy, which allows higher layer network protocols to operate without modification. A PRP node needs only one IP address. Especially, the ARP protocol will correctly relate the MAC to the IP ...
It can also be used to restrict access to or from a particular geographic area; for example, syndicating content to a specific region through the use of Internet geolocation. [1] IP address blocking can be implemented with a hosts file (e.g., for Mac, Windows, Android, or OS X) or with a TCP wrapper (for Unix-like operating systems).
Multihoming is the practice of connecting a host or a computer network to more than one network. This can be done in order to increase reliability or performance. A typical host or end-user network is connected to just one network. Connecting to multiple networks can increase reliability because if one connection fails, packets can still be routed through the remaining connection. Connecting ...
The nodes in the network (typically network switches and routers) take care of replicating the packet to reach multiple receivers such that messages are sent over each link of the network only once. The most common transport layer protocol to use multicast addressing is User Datagram Protocol (UDP). By its nature, UDP is not reliable—messages ...
