tailieunhanh - Lecture TCP-IP protocol suite - Chapter 3: Underlying technology

Upon completion you will be able to: Understand the different versions of wired Ethernet, understand wireless Ethernet, understand the types of point-to-point WANs, understand the types of switched WANs, especially ATM, differentiate between repeaters, bridges, routers, and hubs. | Chapter 3 Underlying Technologies CONTENTS LANS POINT-TO-POINT WANS SWITCHED WANS CONNECTING DEVICES Figure 3-1 Internet model LOCAL AREA NETWORKS (LANS) Figure 3-2 CSMA/CD Minimum frame length/Transmission rate is proportional to Collision domain / Propagation speed Figure 3-3 Ethernet layers Figure 3-4 Ethernet frame Figure 3-5:a Ethernet implementation Figure 3-5:b Ethernet implementation Figure 3-5:c Ethernet implementation Figure 3-5:d Ethernet implementation Figure 3-6:a Fast Ethernet implementation Figure 3-6:b Fast Ethernet implementation Figure 3-6:c Fast Ethernet implementation Figure 3-7:a Gigabit Ethernet implementation Figure 3-7:b Gigabit Ethernet implementation Figure 3-8:a Token passing Figure 3-8:b Token passing Figure 3-8:c Token passing Figure 3-8:d Token passing Figure 3-9 Data frame Figure 3-10 MAU Figure 3-11:a Spread spectrum techniques Figure 3-11:b Spread spectrum techniques Figure 3-12 ISM bands Figure 3-13 BSSs Figure 3-14 ESS Figure 3-15 CSMA/CA POINT-TO-POINT WANS Figure 3-16 Band for ADSL Figure 3-17 PPP frame SWITCHED WANS Figure 3-18 Frame Relay network A cell network uses the cell as the basic unit of data exchange. A cell is defined as a small, fixed-sized block of information. Figure 3-19 ATM multiplexing Figure 3-20 Architecture of an ATM network Figure 3-21 Virtual circuits Note that a virtual connection is defined by a pair of numbers: the VPI and the VCI. Figure 3-22 An ATM cell Figure 3-23 ATM layers The IP protocol uses the AAL5 sublayer. We will discuss IP over ATM in Chapter 26. Figure 3-24:a ATM LAN architecture Figure 3-24:b ATM LAN architecture Figure 3-24:c ATM LAN architecture Figure 3-25 A mixed architecture ATM LAN using LANE CONNECTING DEVICES Figure 3-26 Connecting devices Figure 3-27 Repeater A repeater connects segments of a LAN together. A repeater forwards every packet; it has no filtering capability. Figure 3-28 Hubs A bridge has a table used in filtering decisions. Figure 3-29 Bridge A bridge connects segments of a LAN together. A router is a three-layer (physical, data link, and network) device. A repeater or a bridge connects segments of a LAN. A router connects independent LANs or WANs to create an internetwork (internet). Figure 3-30 Routing example A router changes the physical addresses in a packet. | Chapter 3 Underlying Technologies CONTENTS LANS POINT-TO-POINT WANS SWITCHED WANS CONNECTING DEVICES Figure 3-1 Internet model LOCAL AREA NETWORKS (LANS) Figure 3-2 CSMA/CD Minimum frame length/Transmission rate is proportional to Collision domain / Propagation speed Figure 3-3 Ethernet layers Figure 3-4 Ethernet frame Figure 3-5:a Ethernet implementation Figure 3-5:b Ethernet implementation Figure 3-5:c Ethernet implementation Figure 3-5:d Ethernet implementation Figure 3-6:a Fast Ethernet implementation Figure 3-6:b Fast Ethernet implementation Figure 3-6:c Fast Ethernet implementation Figure 3-7:a Gigabit Ethernet implementation Figure 3-7:b Gigabit Ethernet implementation Figure 3-8:a Token passing Figure 3-8:b Token passing Figure 3-8:c Token passing Figure 3-8:d Token passing Figure 3-9 Data frame Figure 3-10 MAU Figure 3-11:a Spread spectrum techniques Figure 3-11:b Spread spectrum techniques Figure 3-12 ISM bands Figure 3-13 BSSs Figure 3-14 ESS Figure 3-15 CSMA/CA .
