Case Study: P2P Internet Telephony with Skype
Case Study: P2P Internet Telephony with Skype

Skype is an immensely popular P2P application, often with seven or eight million users connected to it at any one time. Besides providing PC-to-PC Internet telephony service, Skype offers PC-to-phone telephony service, phone-to-PC telephony service, and PC-to-PC video

The Link-State (LS) Routing Algorithms
The Link-State (LS) Routing Algorithms

Remember that in a link-state algorithm, the network topology and all link costs are known, that is, available as input to the LS algorithm. In fact this is accomplished by having each node broadcast link-state packets to all other nodes in the network, with each link-state packet

The Distance-Vector (DV) Routing Algorithm
The Distance-Vector (DV) Routing Algorithm

The LS algorithm is an algorithm using global information, the distance-vector (DV) algorithm is iterative, asynchronous, and distributed. It is distributed in that each node receives some information from one or more of its directly attached neighbors, performs a calculation, and then

Link-Layer Addressing
Link-Layer Addressing

Nodes that is hosts and routers have link-layer addresses. Now you might find this surprising, recalling from "The Network Layer" that nodes have network-layer addresses as well. You might be thinking, why in the world do we need to have addresses at both the network and link

MAC Addresses
MAC Addresses

Because there are both network-layer addresses (for instance, Internet IP addresses) and link-layer addresses (that is, MAC addresses), there is a need to translate between them. For the Internet, this is the job of the Address Resolution Protocol (ARP).

Ethernet
Ethernet

Ethernet has pretty much taken over the wired LAN market. In the 1980s and the early 1990s, Ethernet faced many challenges from other LAN technologies, including token ring, FDDI, and ATM. Some of these other technologies succeeded in capturing a part of the LAN market for

CSMA/CD: Ethernets Multiple Access Protocol
CSMA/CD: Ethernets Multiple Access Protocol

When the nodes are interconnected with a hub (as opposed to a link-layer switch), as shown in Ethernet Figure 2, the Ethernet LAN is a true broadcast LAN - that is, when an adapter transmits a frame, all of the adapters on the LAN receive the frame. Because Ethernet can employ
