  1. Tecnologías de Información Sesión Nro. 3 Tendencias en TI Migración y Administración de Redes

  2. Challenges Driving The Business More Local Users and Remote Users New Applications and Computers Internet Resources and Commerce

  3. SLOW Ethernet Operation

  4. Hubs, Switches, Routers • Increase performance • Decrease cost • Secure the environment Layer 3 Layer 2 Layer 1 Level of Intelligence and Complexity

  5. Hubs—Layer 1

  6. Switches—Layer 2 MAC Port Address Table XXX1 Port 1 XXX2 Port 6 XXX3 Port 8 Switch Memory Virtual Connections

  7. Routing Table 131.108.3.0 Frame Relay 131.108.1.0 Ethernet 131.108.2.0 FDDI Routers—Layer 3 Remote Location Network 131.108.3.0 Frame Relay Network 131.108.2.0 FDDI Network 131.108.1.0 Ethernet

  8. Network Congestion • Too many users in a single collision domain • Bandwidth-intensive applications such as publishing, CAD/CAM, and imaging • Networked applications such as support automation software • More servers and high-performance PCs Networked Applications More Users High Bandwidth Applications Internet Access

  13. The Importance of Class II • Extends distances • Cascades hubs, stacks • Reduces network costs Class I Class II Floor 2: Hub Hub Switch Floor 1: Hub Hub

  15. Why Fast Ethernet? • It’s Fast! • Ten times the speed of Ethernet • It’s Simple! • No re-training for MIS and LAN administrators • Runs same applications as today’s 10BASE-T • Uses existing cabling infrastructure • Familiar network management tools • It’s Affordable! • Just twice the price of 10Mps Ethernet • No extra or ‘hidden’ costs Fast Ethernet is Ethernet — Only Faster!

  16. Fast Ethernet Applications 10Mb Segments, 100Mb Downlinks and Servers 10Mb Segments, 100Mb Servers 10/100 Switch 10 Mb Hubs 100 Mb Switch 10/100 Switch 100 Mb Hub 100 Mb Hub

  18. Deploying 100BASE-T ...Peak vs. Aggregate Bandwidth Problem: Aggregate Bandwidth Solution: 10/100 Switching 10/100 Switch ? • Large workgroup • Standard end systems with ISA bus • Continuous loading • Excessive collisions • Eliminates server bottlenecks and scaleable to large networks BUT peak workstation bandwidth still only 10Mbps Problem: Peak Bandwidth Solution: 100Mbps Workgroup 100 Mb Repeater ? • Improves peak performance, but end stations need 100Mbps cards • Switching further increases aggregate bandwidth • High performance systems with EISA or PCI bus • Slow response on large file transfers • Bursty traffic

  19. Understanding Migration Issues • Can my cabling support high-speed networking technologies? • How do I boost performance with minimum cost and disruption to users? • What happens to replaced equipment—can I use it someplace else? • How familiar am I with the new technology—do I need to re-train my staff before an upgrade?
