Bridges, Routers, Switches, and Internetworking Protocols

The concepts of IP addresses, masks, MAC addresses, routing algorithms, domains, switches, bridges, are pervasive when dealing with networks. We all use these terms and configure these things, but what is really going on? What are the implications of choosing a switch vs. a router? What kinds of things can go wrong in a protocol that is misdesigned, misimplemented, or mismanaged? This tutorial describes the major protocols involved in the network infrastructure.

Seminar in Detail: 
  • Layer 2 (MAC) addresses: Why 6 bytes?
  • Relation of layer 2 (MAC) to layer 3 (IP) addresses
  • Bridges: Why it's more powerful than a repeater
  • Spanning tree algorithm used by bridges and switches
  • Routing (distance vector vs. link state, interdomain vs. intradomain)
  • Connection-oriented networks: ATM, MPLS
  • Connectionless protocols: IPv4, IPv6, and comparison with others
Advanced Registration Price: $80.00 Good until Monday, 10/27/2003

Regular Price: $90.00

Radia Perlman is a Distinguished Engineer at Sun Microsystems. She is known for her contributions to bridging (spanning tree algorithm) and routing (link state routing), as well as security (sabotage- proof networks). She is the author of two of the top 10 networking reference books, according to Network Magazine. She is one of the 25 people whose work has most influenced the networking industry, according to Data Communications Magazine. She holds about 50 issued patents, an S.B. and S.M in mathematics and a Ph.D. in computer science from MIT and an honorary doctorate from KTH, the Royal Institute of Technology in Sweden.

MIT is at 77 Massachusetts Avenue, just on the north side of Memorial Drive(on the north shore of the Charles River), in Cambridge, MA.

Map showing the MIT campus. The red building is Bldg. 34; the Kendall T-Station is on Main Street off the right side of the map.

Building 34 is located on Vassar Street about half way between Main Street and Massachusetts Ave. It is a small square building turned 45 degrees to the street so it may look like a diamond, especially with a glass atrium entrance. Building 34 is set back a few yards from the street and the line of other buildings. It is between buildings 36 and 38.

Parking: Vassar Street on the other side of Mass Ave has a parking lot, a garage, and plenty of spaces on the street. MIT West Annex Lot and West Garage
