  1. Planning and Cabling Networks Planning and Cabling NetworksNetwork Fundamentals – Chapter 10
  2. Objectives Học viện mạng Bach Khoa - Website: www.bkacad.com
  3. Objectives  Identify the basic network media required to make a LAN connection.  Identify the types of connections for intermediate and end device connections in a LAN. – Identify the pin out configurations for straight-through and crossover cables. – Identify the different cabling types, standards and ports used for WAN connections. – Define the role of device management connections when using Cisco equipment.  Design an addressing scheme for an inter-network and assign ranges for hosts, network devices and the router interface.  Compare and contrast the importance of network designs Học viện mạng Bach Khoa - Website: www.bkacad.com
  4. LANs – Making the Physical Connections Học viện mạng Bach Khoa - Website: www.bkacad.com
  5. Choosing the Appropriate LAN Device 10.1.1.1
  6. Choosing the Appropriate LAN Device 10.1.1.2 A hub is typically chosen as an intermediary device within a very small LAN, in a LAN that requires low throughput requirements, or when finances are limited. Học viện mạng Bach Khoa - Website: www.bkacad.com
  7. Device Selection Factors 10.1.2.1 Học viện mạng Bach Khoa - Website: www.bkacad.com
  8. Device Selection Factors 10.1.2.2 Học viện mạng Bach Khoa - Website: www.bkacad.com
  9. Device Selection Factors The cost of a switch is determined by 1.Capacity (port available and switching speed) 2.Features 3.Network management capabilities 4.Embedded security technologies 5.Optional advanced switching technologies Học viện mạng Bach Khoa - Website: www.bkacad.com
  10. Device Selection Factors Speed and Types of Ports/Interfaces 10.1.2.3 Học viện mạng Bach Khoa - Website: www.bkacad.com
  11. Device Selection Factors Speed and Types of Ports/Interfaces Would you purchase a switch with: –Just enough ports for today's needs? –A mixture of UTP speeds? –Both UTP and fiber ports? Học viện mạng Bach Khoa - Website: www.bkacad.com
  12. Device Selection Factors 10.1.2.4 Factors to Consider in Choosing a Router  Similar to the switch, cost and interface types and speeds must be considered as well.  Additional factors: 1. Expandability 2. Media 3. Operating System Features Học viện mạng Bach Khoa - Website: www.bkacad.com
  13. Device Selection Factors Expandability 1. Fixed configurations 2. Modular devices 3. Most modular devices come with a basic number of fixed ports as well as expansion slots. 4. Select the appropriate modules and interfaces for the specific media. Học viện mạng Bach Khoa - Website: www.bkacad.com
  14. Device Selection Factors Operating System Features 1. Security 2. Quality of Service (QoS) 3. Voice over IP (VoIP) 4. Routing multiple Layer 3 protocols 5. Special services such as NAT and DHCP Học viện mạng Bach Khoa - Website: www.bkacad.com
  15. Device Interconnections Học viện mạng Bach Khoa - Website: www.bkacad.com
  16. LAN and WAN – Getting Connected 10.2.1.1 (vertical cabling) (Distribution cabling) Học viện mạng Bach Khoa - Website: www.bkacad.com
  17. Extra: LAN design  Main Distribution Facility (MDF).  Intermediate Distribution Facilities (IDFs)  Point of Presence (POP) Học viện mạng Bach Khoa - Website: www.bkacad.com
  18. LAN and WAN – Getting Connected (permanent link ) Học viện mạng Bach Khoa - Website: www.bkacad.com
  19. LAN and WAN – Getting Connected Telecommunications Room  Is where connections to intermediary devices take place.  Patch cords connects between the patch panels and the intermediary devices.  Patch cables also interconnect these intermediary devices.  Also contains the servers used by the network. Học viện mạng Bach Khoa - Website: www.bkacad.com
  20. LAN and WAN – Getting Connected Horizontal Cabling  To connect the telecommunication rooms with the work areas, 90 meters max.  This 90 meter maximum horizontal cabling distance is referred to as the permanent link because it is installed in the building structure. Backbone Cabling, or vertical cabling  To connect the telecommunication rooms to the equipment rooms, where the servers are often located. Also interconnects multiple telecommunications rooms. Sometimes routed outside the building to the WAN connection or ISP.  Be used for aggregated traffic. Backbones typically require high bandwidth media such as fiber-optic cabling.
