Outcomes

• The purpose of SSD8 is for students to – Learn about the elements of the structure and

function of the Internet that are most important to application system developers.

– Learn to use Internet protocols in application development.

– Learn the principles of distributed system design. – Learn to build distributed systems using the most

important current technical approaches.

5

Outcomes cont’d 1

• Students successfully completing SSD8 will be able to PRODUCE– Programs using TCP sockets to communicate across

an IP network – Programs that act as clients using common Internet

protocols like FTP, HTTP, and SMTP – Distributed objects to be managed by an object

request broker (ORB) – Distributed applications based on existing and new

distributed objects managed by and ORB

6

Outcomes cont’d 2

• Students successfully completing SSD8 will be able to USE– Internet RFCs and other reference material for protoc

ol specification – Common Internet tools (such as nslookup, ping, trace

route, netstat) to observer and evaluate network performance and function

– An object request broker's services in constructing a distributed application

and its application to TCP/IP – Fundamental concepts including abstraction, encapsu

lation, multiplexing and demultiplexing – The structure and function of the most popular layer 1

and 2 networks: Ethernets, ATM, Sonet, ADSL, ISDN, and WDM

performance, robustness, and modularity – The functionality of an ORB and the general attributes

of popular ORB systems (CORBA and DCOM) – The issues of replication, consistency, and fault

tolerance in distributed applications
