Tunneling is a way in which data is transferred between two networks securely. All the data that is being transferred are fragmented into smaller packets or frames and then passed through the tunnel. This process is different from a normal data transfer between nodes. Every frame passing through the tunnel will be encrypted with an [...]

Connectionless internetworking follows the datagram model. In this model, the network layer offers the transport layer the ability to inject datagrams into the subnet. There is no notion of a virtual circuit at all in the network layer. This model does not require all packets belonging to one connection to traverse the same sequence of [...] Two styles of internetworking are common: * a connection-oriented concatenation of virtual circuit subnets, * a datagram internet style. In the concatenated virtual circuit model, a connection to a host in a distant network is set up in a way similar to the way connections are normally established. The virtual circuit consists of concatenated [...] What are we talking about ? The interconnection of two or more networks, usually local area networks so that data can pass between hosts on the different networks as though they were one network. This requires some kind of router or gateway to facilitate the process of interconnecting two or more individual networks to facilitate [...] |
