.... Some research studies have considered the issue of workloads with transient overload, but these studies have focused on single class workloads and specific scheduling strategies, such as admission control (e.g. 8] and direct modifications to the Internet server scheduling mechanism (e.g. [2, 5]) In contrast, our focus in this paper is on the optimal dynamic scheduling of a multiclass system with transient overload. Furthermore, very little research has even attempted to consider the issue of maximizing profit in these computing paradigms under non conventional performance metrics. The ....

....time. The mechanism described here seems overly complex, and 42 details on request classification and the actual rejection mechanism are not discussed. A related technique, proposed by the same group, allocates requests to Apache server processes to minimize per class response time bounds [27]. A weight is assigned to each class of requests to maximize a server productivity function, defined in terms of the number of pending requests in each class, a (fixed) per class processing time requirement, and a (fixed) delay bound. The paper is very unclear on implementation details and how ....
....management a first class application design primitive, rather than an operating system function with generic load shedding policies. 1. 1 Performance metrics A variety of performance metrics have been studied in the context of overload management, including throughput and response time targets [27, 28], CPU utilization [3, 30, 37] and 146 differentiated service metrics, such as the fraction of users in each class that meet a given performance target [72, 89] We focus on 90th percentile response time as a realistic and intuitive measure of client perceived system performance, defined as ....

....of requests or bytes serviced in a certain time quantum. While the transaction latency refers to the time interval between when a request sent to the server and the response s arrival at the end user. We argue that the two metrics are not sufficient to assess the user perceived performance. In [4], we justified that server throughput is not an appropriate measurement in session based web traffic like e commerce. Similarly transaction latency cannot capture the user s reaction as well. For instance, consider two scenarios of transmitting of a web page with 30 seconds latency. In the first ....
