To expand on the above, a helpful quote: http://h71000.www7.hp.com/doc/73final/6556/6556pro_021.html --- A.3.2 NetBEUI Protocol The NetBIOS Extended User Interface (NetBEUI) was first introduced by IBM in 1985. NetBIOS, an integral part of the NetBEUI protocol driver, is a programming interface that implements many session layer functions. NetBEUI is a small, efficient, and fast protocol with low overhead. Note "Overhead" in this context refers to the additional network control information, such as routing and error checking, that the protocol adds to data that the application layer needs to send across the network. One reason for NetBEUI's lower overhead is that NetBEUI does not require an explicit acknowledgment (ACK) of each frame before it sends the next. Instead, the computer packages up several ACKs and sends them all at once. Requiring an ACK for every packet wastes network resources. NetBEUI dynamically determines the number of frames the sender can transmit before receiving an ACK, based on the network's current conditions. NetBEUI was developed for LANs segmented into workgroups of 20 to 200 computers, with gateways connecting LAN segments to one another or to mainframes. NetBEUI is optimized for very high performance when used in departmental LANs or LAN segments. For traffic within a LAN segment, NetBEUI typically is the fastest protocol. While NetBEUI is fast on small LANs, it is not so effective on large networks because it has a poor addressing scheme. NetBEUI does not allow duplicate computer names on the same network. This prevents a network from having two computers with the same name---something difficult to eliminate on a large network. Table A-3, NetBEUI Protocol, summarizes the advantages and disadvantages of the NetBEUI protocol. --- I haven't used Netbeui on my small LAN since I stopped using IBM OS/2 WSeB FC -- During times of Universal Deceit, telling the truth becomes a revolutionary act Durante épocas de Engaño Universal, decir la verdad se convierte en un Acto Revolucionario - George Orwell -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
