Hub Hub • A hub (sometimes called a multi-port repeater ) operates at Open Systems I nterconnection (OSI ) reference model layer 1, which organizes data into bits , which are binary sequences of 0s and 1s used to transmit data across a wired or wireless network. – I t does not perform any sort of processing against the data it receives. – I nstead, it simply receives the incoming signal and recreates it for transmission on all of its ports. Switch Switch • A switch examines the destination and source address of an incoming data frame, and forwards the frame to the appropriate destination port according to the destination address. – Most switches operate at OSI layer 2 (the Data-link Layer ), which organizes data into fr ames . Router Router • A r outer determines routes from a source network to a destination network. • Where to send network packets based on the addressing in the packet. • Routers operate at OSI layer 3 (the Network Layer ), which groups data into packets . – They are referred to as Layer 3 devices . Router Router • To join networks together over extended distances or WANs. – WAN traffic often travels over multiple routes, and the routers choose the fastest or cheapest route between a source computer and destination. • To connect dissimilar LANs, such as an Ethernet LAN, to a Fiber Distributed Data I nterface (FDDI ) backbone. Router Router Router Router Routing Protocols Routing Protocols • Used to automatically transmit information about the routing topology and which segments can be reached via which router. • Whereas both RI Pv2 and OSPF were supported under Windows Server 2003, only RI Pv2 is supported by Windows Server 2008. Routing I nformation Protocol (RI P) Routing I nformation Protocol (RI P) • One of the most long-standing routing protocols; • Broadcasts information about available networks on a regular basis, as well as when the network topology changes. • RI P is broadcast-based—that is, it sends out routing information in broadcast packets that are transmitted to every router that is connected to the same network....
