High Level Design

• Design Issues -
• Reusability
• Some components may be designed to be reusable
• Maintainability
• Need to be taken care of
• Customer may want add new functions and new
  services type
• Detailed documentation.

High Level Design

• Design Issues -
• Portability
• Need to be taken care of
• The software needs to be run on different
  Operating System Windows or Linux.
• Security
• Not important
• Does not contain sensitive information
• Only one user Network Administrator

Data Format

• Service Configuration
• Name, Type, Timeout, Port, Check interval,
  Notification.
• Type includes http, ftp, ssh, tcp, smtp, pop3,
  mssql, imap, tcp-connection.
• Log message
• "service_type on addressport up/down at
  occuring_time
• For example "ftp on yahoo21 down at 130
  afternoon".
• Statistical chart
• Number of faults at each logging time

Trace of Requirements to Design

• Functional Requirements
• For Fundamental actions
• Allows the validity checking when loading a
  servers IP address list, if the format is not
  correct, an error message will pop-up.
• Finished the implementation
• Check use case diagram above for exact sequence
  of operations.
• Finished the implementation
• Use JAVA ICMP packages to get required results
• Finished the implementation

16
Trace of Requirements to Design

• Interface Requirements
• Input data items Server IP address list
  (including the Ip address, the server type, the
  server port) gt Implemented, see the GUIs
• Output data items
• Statistical analysis in a period of time.
• Finish the implementation
• Error messages in the case of invalid data input
• Will be implemented in the implementation phase.
