Web Workload Generation According to the UniLoG Approach
Generating synthetic loads which are sufficiently close to reality represents an important and challenging task in performance and Quality-of-Service (QoS) evaluations of computer networks and distributed systems. Here, the load to be generated represents sequences of requests at a well-defined service interface within a network node. The paper presents a tool (UniLoG.HTTP) which can be used in a flexible manner to generate realistic and representative server and network loads, in terms of access requests to Web servers as well as creation of typical Web traffic within a communication network. The paper describes the architecture of this load generator, the critical design decisions and solution approaches which allowed them to obtain the desired flexibility.
