Research on universal network Performance Testing model
2007 International Symposium on Communications and Information Technologies, 2007Co-Authors: Changyou Xing, Guomin Zhang, Ming ChenAbstract:Network Performance Testing is one of the key components in optimizing network resource configuration and improving network Performance. Existing Performance Testing tools usually focus on single Performance parameters, and lack of the ability to satisfy integrated Testing demands of network administrators. In this paper, a universal network Performance Testing model based on policy scheduling is proposed, which integrates many kinds of Performance Testing tools into a single system, and provides a uniform Testing interface to network administrators. Universal Probe (UP) is the key component of such a model, thus a detailed study is given on UP, which includes UP architecture, policy-based UP cooperation, mobility, and UP deployment under resource constraints. At last, a practical Network Monitor and Measurement System that designed based on the discussed concepts is presented.

the design and implementation of a domain specific language for network Performance Testing
IEEE Transactions on Parallel and Distributed Systems, 2007Co-Authors: Scott PakinAbstract:CONCEPTUAL is a toolset designed specifically to help measure the Performance of high-speed interconnection networks such as those used in workstation clusters and parallel computers. It centers around a high-level domain-specific language, which makes it easy for a programmer to express, measure, and report the Performance of complex communication patterns. The primary challenge in implementing a compiler for such a language is that the generated code must be extremely efficient so as not to misattribute overhead costs to the messaging library. At the same time, the language itself must not sacrifice expressiveness for compiler efficiency, or there would be little point in using a high-level language for Performance Testing. This paper describes the CONCEPTUAL language and the CONCEPTUAL compiler's novel code-generation framework. The language provides primitives for a wide variety of idioms needed for Performance Testing and emphasizes a readable syntax. The core code-generation technique, based on unrolling CONCEPTUAL programs into sequences of communication events, is simple yet enables the efficient implementation of a variety of high-level constructs. The paper further explains how CONCEPTUAL implements time-bounded loops - even those that comprise blocking communication - in the absence of a time-out mechanism as this is a somewhat unique language/implementation feature.

Passive Performance Testing of network protocols
Computer Communications, 2014Co-Authors: Xiaoping Che, Stephane MaagAbstract:Complementary to Performance evaluation, Performance Testing of communicating protocols is a qualitative and quantitative test of a system, aiming at checking whether Performance requirements of protocols have been satisfied under certain conditions. It raises an interesting issue of accurately formalizing specified Performance requirements by taking consideration of data values of the protocol messages. In this paper, we present a novel logic-based Testing approach to check protocol Performance requirements through real execution traces and formally specified properties. In order to evaluate and assess our methodology, we develop a prototype and present experiments through a set of Session Initiation Protocol (SIP) properties. Finally, a Performance benchmark method is proposed and relevant verdicts and discussions are provided

A formal passive Performance Testing approach for distributed communication systems
2013Co-Authors: Xiaoping Che, Stephane MaagAbstract:Conformance Testing of communicating protocols is a functional test which verifies whether the behaviors of the protocol satisfy defined requirements, while the Performance Testing of communicating protocols is a qualitative and quantitative test, aiming at checking whether the Performance requirements of the protocol have been satisfied under certain conditions. It raises the interesting issue of converging these two kinds of test by using the same formal approach. In this paper, we present a novel logic-based approach to test the protocol Performance through real execution traces and formally specified properties. In order to evaluate and assess our methodology, we have developed a prototype and present experiments with a set of IMS/SIP properties. Finally, the relevant verdicts and discussions are provided
