These approaches need a guarantee in terms of throughput, the performance of which they potentially impact. So, the basic aim of this research is to get the best MPLS network performance towards linux and FreeBSD operating systems. This is why in this report, we have worked on MPLS network performance, which will help to identify performance metrics. To evaluate the performance, we used those operating systems implementing the MPLS architecture in order to define the best performing between the two on this domain. For this, we used scapy to measure the response times by varying the size of the packets sent and validate the measurements with the MATLAB Simulink. After all experiments, we realized that FreeBSD operating system is more reliable than linux in MPLS network base.展开更多

The safety of information systems becomes essential. This is why the performance linked to security codes is of importance essential in the security systems of all companies. Indeed, as contribution, to carry out measurements, it appropriates tools that are the JMH tool (Java Microbenchmark Harness) and the PHP Benchmark script tool which include unsecure java and PHP codes and secured against SQL (Structured Query Language) injection, XSS (Cross Site Scripting) <i><span>i.e.</span></i><span>, using prepared requests, stored procedures, validation of input from white lists, reinforcement of minimum privilege, when sending requests from the last ones to MySQL databases and Postgresql. We recover the times of response to his requests. From java codes and PHP (Hypertext Preprocessor) secure, we also retrieve the response time for requests to databases MySQL and PostgresqL data. We then obtain the curves and interpretations comparing performance related to security and non-security of codes. The goal is to analyze and evaluate the performance comparing secure Java and PHP code against unsecure java and PHP code using MySQL and Postgresql databases. In Section 1, we presented the performance of the code Java and PHP. The configuration of the experiments and the experimental results are discussed in Sections 2 and 3, respectively. Use of suitable tool which is the JMH tool and the PHP Benchmark script tool, we have developed in Java 1.8 and PHP 7.4 secure and non-secure codes that send the queries to the MySQL or Postgresql database to carry out the measurements which led to the conclusion that the insecure PHP and Java codes are faster in terms of response time compared to the PHP and Java secure codes as the number of tables linked to the query increases because the blocking times of SQL injection and XSS prevention展开更多
