Wans and routers

  1. 1. WANS and ROUTERS Presented by Les McLellan Dean Whittaker Sandy Workman
  2. 2. WANS and ROUTERS  What is a WAN?  WAN Devices  WAN Standards  WAN Technologies  What is a Router ?  Summary
  3. 3. What is a WAN? A Data Communications Network  Network Services provided by PTO’s  Relatively broad geographic area  Serial connections of various types and speeds  Provide full and part time connectivity  Technologies function at the lower three layers of the OSI Model
  4. 4. Wide Area Network Devices  Routers  WAN Bandwidth Switches  Modems  Comms Servers
  5. 5. WAN Standards  Defined and Managed by recognized authorities  WAN’ s use the OSI reference Model  WAN Physical Layer standards specify the interface  WAN data Link protocols
  6. 6. The WAN Physical Layer  EIA/TIA 232  EIA/TIA 449  V 24  V 35  X 21  G 703  EIA-530
  7. 7. Serial Interface Adaptor Cables
  8. 8. The WAN Data Link Layer  High Level Data Link Control (HDLC)  Frame Relay  Point to Point Protocol (PPP)  Serial Line Interface Protocol (SLIP)  Cisco / IETF  ISDN
  9. 9. WAN Technologies  Dedicated Lines  Switched Connections  (Circuit Switched)  (Packet Switched)  Other WAN Technologies
  10. 10. Dedicated Lines  T1 – 1.544 Mbps  T3 – 44.736 Mbps  E1 – 2.048 Mbps  E3 – 34.368 Mbps  Other Bandwidths are also available
  11. 11. Switched Connections Circuit Switched  POTS  ISDN Packet Switched  X 25  Frame Relay  ATM  SMDS
  12. 12. Other WAN Services  Dial Up Modems  Cable Modems  Wireless
  13. 13. ROUTERS  Internal Components
  14. 14. The Function of a Router
  15. 15. WANS and ROUTERS  Summary  Data Communication Networks that operate over a large area using Serial Links  Routers are active intelligent nodes used to manage a network
  16. 16. WANS and ROUTERS THE END
