Overview of Point-to-point Protocol: The Point-to-Point Protocol (PPP) provides a standard method for transporting multi-protocol datagrams over point-to-point links. PPP was originally emerged as an encapsulation protocol for transporting IP traffic between two peers.PPP is comprised of the following main components: * Encapsulation: A method for encapsulating multi-protocol datagrams. * Link Control Protocol: The LCP [...] 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 [...] Wide Area Networks, or WAN, span a large geographical area. A WAN contains a collection of machines intended for running user programs. Transmission rates are typically 2 Mbps, 34 Mbps, 45 Mbps, 155 Mbps, 625 Mbps, etc. The machines are connected by a subnet whose job is to carry messages from machine to machine. The [...] |
