Virtual LANs In an organization, does it matter which users are on which LAN? LAN administrators prefer to group users to reflect organizational structure, rather than physical layout.
Departments want to isolate their activities from Ethernet stations acting in promiscuous mode in other departments.
Load distribution affects LAN organization
Limiting broadcasting to a single LAN saves bandwidth But, in an organization people’s responsibilities change, and the organizational structure changes even when their physical location does not change.

Layout Managers In this lecture we concentrate on the Placement of components on the viewing surface of the applet. We are still primarily concerned with the appearance of the applet and not its functionality. We will add event listeners to the GUI components in a later lecture to create a useful applet.
TCP/IP Application Model Application TCP UDP IP Network Protocols Protocol Stack
IP Datagrams IP is the protocol for delivering packets over a heterogeneous collection of intercoonnected networks – the Internet. Its primary goal is to make the Internet as inclusive as possible. In order to provide this service, it must address the following concerns: Addressing – the naming of networks, hosts, and applications Address translation – the mapping between global and local names Routing – the delivery of IP packets to their destination Resource location – the discovery of the IP address of an application Fragmentation – adjusting to the packet sizes of the undelying networks
The Domain Name Server The domain name hierarchy is partitioned into zones Each name server holds information relating to its zone This zone information is implemented as a collection of records. Each record contains the following fields:
