Catalog Description :
|
A study of computer networks focusing on the tcp/ip Internet protocols and covering
the four layers: physical, data link, network, and transport, in detail. This course
includes a 2 1/2 hours per week laboratory in which students will cover important
network utilities, debugging tools, process and thread control as it relates to
network programming, and the coding of programs which do interprocess
communication over sockets. The typical Internet client program which accesses a
tcp network server daemon will be covered in detail.

Topics:
|
-
Introduction to net-centric computing (NC1): Historical development of computer networks,
LAN's and WAN's, network architecture, introduction of desirable features
and applications which a computer network should support; discussion
of network topology, latency, bandwidth, and network architecture;
Internet protocol versus the ISO 7-layer recommendations
-
Communication and networking (NC2): Network standard, the 4-layer Internet standard (physical,
datalink, network, and transport), the ISO 7-layer reference model
and why it croaked (perhaps two more layers, "political" and "profit,"
should have been added), circuit versus packet switching, stream versus datagram service,
Physical layer networking concepts, data link layer concepts,
Transport layer services, Internetworking and routing.
-
Protocols, sessions, processes, and threads; coding
problems which arise from differences between operating systems
(e.g. Unix vs. Windows NT/2000/XP).
-
The physical layer and lower datalink layer (media
access control) of the network; bandwidth and
Shannon's law; encoding, framing, and error detection; reliable
transmission and link protocols (stop & wait, sliding window, etc.);
point-to-point versus multiple access local-area networks (LANs),
case studies (RS-232, HDLC, ethernet and IEEE 802.3, token rings,
token bus); design of the network adapter card and driver.
-
The full datalink layer, combining links with
switches, virtual circuits versus datagrams; introduction to
routing strategies and more on network topology; fixed size versus
variable size frames, case study of ATM.
-
The network layer (which may be absent in broadcast
LANs); building wide-area networks (WANs) from LANs and nodes,
repeaters, bridges and routers;
the Internet IPv4 protocol in detail; global addressing
and address translation between the network and datalink layers
( arp ); error reporting by nodes; icmp packets; symbolic
host names, aliases and the domain name service (DNS).
-
The transport layer and end-to-end protocols; the
Internet udp and tcp protocols in detail.
-
Network security (NC3): Basic network security issues, the natural insecurity of the
physical media, authentication.
-
client-server computing (NC4): Client-server protocol and program structure,
tcp protocols and tcp servers.

Laboratory:
|
The laboratory session will parallel the lecture, illustrating
the principles and familiarizing the student with writing network
application programs in C , using a standard BSD socket
interface. This will include introducing the student to
some associated process control, and special I/O system calls.
We will also discuss the closely related winsock.dll
programming on Windows NT/2000/XP.
