“…Furthermore, our conclusions suggest that network service providers do not have to invest in servers that require kernel-level infrastructure development just for performance. In fact, another study of our server [23] suggests that availability is another reason why relying on user-level communication is a good idea.…”

Abstract-In this paper, we propose and evaluate a cluster-based network server called PRESS. The server relies on localityconscious request distribution and a standard for user-level communication to achieve high performance and portability. We evaluate PRESS by first isolating the performance benefits of three key features of user-level communication: low processor overhead, remote memory accesses, and zero-copy transfers. Next, we compare PRESS to servers that involve less intercluster communication, but are not as easily portable. Our results for an 8-node server cluster and five WWW traces demonstrate that user-level communication can improve performance by as much as 52 percent compared to a kernel-level protocol. Low processor overhead, remote memory writes, and zero-copy all make nontrivial contributions toward this overall gain. Our results also show that portability in PRESS causes no throughput degradation when we exploit user-level communication extensively.

“…The article by [20] suggested an FCM technique in the form of an efficient fuzzy clustering-based algorithm to detect potential attacks in an efficient intrusion detection system for implementing mobile ad hoc networks (MANETs) into cloud-based storage environments. [21] discovered the availability and performance of cluster-based services. They used fault injection techniques and analytical modelling for evaluating the availability and performance of networks which use protocols, such as TCP and VIA.…”

This paper explains how the commonly occurring DOS and Brute Force attacks on computer networks can be efficiently detected and network performance improved, which reduces costs and time. Therefore, network administrators attempt to instantly diagnose any network issues. The experimental work used the SNMP-MIB parameter datasets, which are collected via a specialised MIB dataset consisting of seven types of attack as noted in section three. To resolves such issues, this researched carried out several important contributions which are related to fault management concerns in computer network systems. A central task in the detection of the attacks relies on MIB feature behaviours using the suggested SFCM method. It was concluded that the DOS and Brute Force fault detection results for three different clustering methods demonstrated that the proposed SFCM detected every data point in the related group. Consequently, the FPC approached 1.0, its highest record, and an improved performance solution better than the EM methods and K-means are based on SNMP-MIB variables.

“…In particular, we use our methodology to evaluate the impact of three different strategies for managing soft state in a multitier bookstore service. (We have also successfully used our methodology to study the performability trade offs of different designs and environmental factors, including the impact of different communication protocols, error recovery strategies, hardware reliability, and operator response time, on a clusterbased Web server [27], [25], [26].) In this section, we first give some background on multitier services, discuss the state maintenance strategies that we will study, and present some details of the bookstore service.…”

Abstract-In this paper, we propose a two-phase methodology for systematically evaluating the performability (performance and availability) of cluster-based Internet services. In the first phase, evaluators use a fault-injection infrastructure to characterize the service's behavior in the presence of faults. In the second phase, evaluators use an analytical model to combine an expected fault load with measurements from the first phase to assess the service's performability. Using this model, evaluators can study the service's sensitivity to different design decisions, fault rates, and other environmental factors. To demonstrate our methodology, we study the performability of a multitier Internet service. In particular, we evaluate the performance and availability of three soft state maintenance strategies for an online bookstore service in the presence of seven classes of faults. Among other interesting results, we clearly isolate the effect of different faults, showing that the tier of Web servers is responsible for an often dominant fraction of the service unavailability. Our results also demonstrate that storing the soft state in a database achieves better performability than storing it in main memory (even when the state is efficiently replicated) when we weight performance and availability equally. Based on our results, we conclude that service designers may want an unbalanced system in which they heavily load highly available components and leave more spare capacity for components that are likely to fail more often.
