Configuration of bridges

  1. 1. PRESESENTATION<br />ON <br />CONFIGURATION<br />BRIDGES.<br />Presented By:<br />SWASTI ARYA<br />
  2. 2. WHAT ARE BRIDGES?<br /><ul><li>Internetworking device.
  3. 3. Filters data traffic at a network boundary.
  4. 4. Operates in both the physical and the data link layer of the OSI model.
  5. 5. As a physical layer device, it regenerates the signal it receives. As a data link layer device, the bridge can check the physical addresses contained in the frame.
  6. 6. Ethernet bridge, for example, inspects each incoming Ethernet frame.</li></li></ul><li>WIRELESS ETHERNET BRIDGES<br />
  7. 7. TYPES OF BRIDGES<br /><ul><li>Transparent Bridge-
  8. 8. The stations are completely unaware of the bridge’s existence.
  9. 9. Reconfiguration of stations is unnecessary.
  10. 10. Function are filtering frames, forwarding & blocking.
  11. 11. Source Routing Bridge-
  12. 12. Much of the bridging functions are performed by end systems, particularly the source.
  13. 13. A sending station defines the bridges that the frame must visit.
  14. 14. It was designed by IEEE to be used with token ring LANs.</li></li></ul><li>CONFIGURATION OF BRIDGES<br /><ul><li>Network Bridge, is a feature of the Network Connections folder that allows a computer with multiple network adapters to act as a bridge, connecting different local area network (LAN) segments.
  15. 15. Required to connect different networking technologies such as a wired Ethernet segment and a wireless segment.
  16. 16. It is a new feature in Windows XP & there is no need to purchase an additional hardware-based bridge device.
  17. 17. Requirement- network adapters installed for all the LAN segments.</li></li></ul><li>A BRIDGE CONNECTING TWO LAN SEGMENTS <br />(A & B)<br />

  21. 21.
  22. 22.
  23. 23. All systems on the network are now accessible in “My Network Places”. <br />
  24. 24. DISABLING AND REMOVING THE BRIDGE<br /><ul><li>To disable the bridge, right-click its icon and choose Disable from the context menu.
  25. 25. To remove a connection from the bridge, right-click the connection’s icon (not the bridge icon) and select Remove From Bridge.</li></li></ul><li>ADVANTAGES<br /><ul><li>Self-configuring.
  26. 26. Primitive bridges are often inexpensive.
  27. 27. Reduce the size of collision domain by micro segmentation in non-switched networks.
  28. 28. Transparent to protocols above the MAC layer.
  29. 29. Allows the introduction of management/performance information and access control.
  30. 30. LANs interconnected are separate, and physical constraints such as number of stations, repeaters and segment length don't apply.
  31. 31. Helps minimize bandwidth usage.
  32. 32. used to interconnect two LANs.</li></li></ul><li>DISADVANTAGES<br /><ul><li>Does not limit the scope of broadcasts.
  33. 33. Does not scale to extremely large networks.
  34. 34. Buffering introduces store and forward delays; on average traffic destined for bridge will be related to the number of stations on the rest of the LAN.
  35. 35. Bridging of different MAC protocols introduces errors.
  36. 36. Because bridges do more than repeaters by viewing MAC addresses, the extra processing makes them slower than repeaters.
  37. 37. Bridges are more expensive than repeaters.</li></li></ul><li>DIFFERENCE BETWEEN BRIDGES & ROUTERS<br />BRIDGES<br />ROUTERS<br /><ul><li>Works at the DLL.
  38. 38. Works with MAC (physical addresses).
  39. 39. Provides a single path from one network segment to another.
  40. 40. Works at the network layer.
  41. 41. Works with IP (logical addresses).
  42. 42. Routers are more sophisticated devices than bridges.</li></li></ul><li>THANKYOU…!!!<br />QUERIES..??<br />DOUBTS..??<br />
