Abstract
This thesis provides a system architecture of intelligent switching design. It consists of five main modules: Network Management based on SNMP model and sysLogs monitoring, Data Analysis focusing on network performance (mainly availability and response time mainly), Switching Decision using server load balancing algorithms (SLB), Feedback Information Control approaching with connection quality (QoS) and Cisco Dynamic Feedback Protocol (DFP), and Server Farms that provide available network resources. As an application example of system design, the prototype of SmartSwitch Router, a kind of TCP traffic intelligent redirector, is provided regarding the issue of implementation. The software design of TCP Redirector is implemented in the Java programming language based on objected-oriented design (OOD) and objected-oriented programming (OOP). In addition, a three-tier architecture of Linux virtual load server clusters (VLSC) is presented in this thesis, with three kinds of Linux VLSC strategies over IP Networks,i.e., VLSC/NAT (via NAT), VLSC/TUN (via IP tunnel), and VLSC/DR (via direct routing).
