Policy-based network load management

Abstract

The problem of managing load is deceivingly simple and appears in almost all types of technology solution offerings. 3,4 Essentially, it is a contention for limited resources. From the perspective of providing service over the Internet (for example, hypertext transfer protocol [HTTP], file transfer protocol [FTP], and telnet), a major problem is contention for the server resources that promise and provide these services. The delay perceived by an end user (client) in the Internet is a function of server response delay and network delay (for example, from routers and switches), where the latter is the more prominent bottleneck in many cases. Still, a server's response time to a request may become unacceptably high, far exceeding network propagation and congestion delays, when

Network management: Emerging trends and challenges

“…They also describe the challenges and opportunities in implementing effective policy-based network management. The paper "Policy-Based Network Load Management" by Hossain et al 29 describes the design and implementation of the prototype of a policy-based load management system. The technique used in the prototype can intelligently manage incoming Internet service requests among a group of servers, resulting in QoS improvement.…”
