One Minute Evaluations for 29 January 2004

CS 537 - Client-Server Interfaces

• Topic: TCP/IP Protocols.

• Topic: Distributed communication networks and how the model of client-server comes up. Protocols and a bit about sockets.

• Topic: Distributed computing methods (architectures) client-server [?].

  Question: How is Napster not a peer-to-peer network?

  One minute response: It had a central point of coordination and no peer-peer discovery. In its original form, Napster served as a central directory of peers; everybody using Napster first queried the central server and got back a list of likely peers.

• Topic: IP, TCP, UDP, protocols.

• Topic: Distributed computing, TCP, UDP, sockets.

• Topic: TCP, sockets, UDP, connections/connectionless, reliability of networks, best protocol to use if reliable.

• Topic: We talked about distributed network models and the basic concept of TCP/IP and UDP protocols.

  Question: No questions.

• Topic: We talked about IP connections in general, TCP and UDP.

  Question: HTTP uses TCP/IP connections. Can UDP do the job?

  One minute response: No. HTTP depends entirely on the underlying protocol to provide transport relability, of which UDP has none.
