Efficient, reliable and security data services are the basis
of ensuring system normal operation. As the bridge
connecting GUI and data source, JDBC (Java Database
Connectivity) [5] realizes data storage and retrieval on web
pages. The communication among GUI, manager and agent
uses Socket [6] technology by opening communication ports
then transmitting and receiving application information. The
JavaApplet [7] technology draws network topological graph,
flow statistic graph, blocking probability graph and so on
real-timely and dynamically after obtaining management
data from database. To endow the web pages vividness,
simplicity, dynamic and cross-platform characteristics,
JavaScript [8] technology extends web page special effect
and meets humanistic requests for management.
