Quick Tech Tip: Point-to-point tunneling protocol – PPTP
Filed Under Network, Techniques, Tips | Posted on July 23, 2009
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 [...]
Quick Tech Tip – Connectionless Internetworking
Filed Under Network, Technical, Tips | Posted on July 21, 2009
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 [...]
Quick Tech Tip: Concatenated Virtual Circuits
Filed Under Network, Technical, Tips | Posted on July 16, 2009
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 virtual [...]
Quick Tech Tips: Wide Area Networks – WAN
Filed Under Network, Technical, Tips | Posted on July 12, 2009
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 [...]
