ECONETS: Learning Resources 1. Text book: Network Design Using EcoNets, International Thomson Computer Press,1997 2. Slide Show (SS1,SS2,SS3,SS4) 3. VCR Tapes for only distance-learning students.
ECONETS: Learning Resources (Contd.) 1. The Textbook is ideal for an in-depth study of all networking ideas, concepts and equations, 2. The slide show highlights only the main ideas and concepts, 3. The VCR tapes describes the actual hands-on design process for remote students.
CONCEPTS: Networks • Nature provides many examples of beautiful networks (e.g. human circulatory or a neural networks) • Humans also create many types of useful networks(e.g broadcast, highways, railroads, freight trucking and oil /gas pipelines)
Some Models of Enterprise Networks (On an Informal Basis Only)
SW SW Examples of a Star Topologies: LANs S AL PABX/LAN S SW= PABX/PS/ StarLAN / EtherSwitch
Access Methods: Demand Access • According to this scheme, a subscriber goes off-hook, gets a dial tone before dialing the called number. • Generally employed by voice network based on CS technology • Several data networks also use this method
Access Methods: Multi- Access • According to this scheme, a station starts transmission after satisfying a set of network requirements. During heavy loading, collisions may occur in some systems. • Generally employed by LANs (e.g. Ethernet, token ring) although some WANs (e.g. ALOHA) also use it.
Class Assignment Based on the language developed for modeling any network, please model an Advanced Intelligent Network (AIN). You may use any search engine on the Internet but you must convert their description to the ones developed in the class. Please limit the model to one (1) page or less.
