IxLoad - Layer 4-7 Performance Testing of Content Aware Devices and Networks

Transcription

1 IxLoad - Layer 4-7 Performance Testing of Content Aware Devices and Networks IxLoad is a highly scalable solution for accurately assessing the performance of content-aware devices and networks. IxLoad creates real-world traffic scenarios at the TCP/UDP (Layer 4) and Application (Layer 7) layers. IxLoad can emulate clients and servers for Web (HTTP and SSL), FTP, (SMTP, POP3 and IMAP), Streaming (RTP and RTSP) and services such asdns, DHCP, LDAP and Telnet. IxLoad also provides emulation of DDOS attacks inline with the above protocols. IxLoad operates in conjunction with Ixia s optimized hardware test platform including the ApplicationLoad Module (ALM), the Gigabit TXS family of Ethernet Load Modules and 10G Ethernet Load Modules. Each port of these modules has a CPU running the Linux operating system with a standards-compliant TCP/IP protocol stack and can emulate thousands of users. p. 1

4 Integrated, Scalable Platform IxLoad runs on Ixia s integrated hardware platform. IxLoad can emulate clients and servers on the same platform - even on a single Load Module. The performance of the platform can be increased by simply adding Load Modules to the same chassis. Each port of the Ixia Load Modules runs a version of the Linux Operating System and supports the Linux TCP/IP protocol stack. The Ixia Load Modules are multi-purpose and support several other Ixia performance applications. Flexible Traffic Setup Traffic volume on IxLoad servers and clients can be controlled independently, allowing for simulation of server failures and switchovers. Each protocol activity can be individually assigned a specific test objective during test configuration and the objective value be modified at runtime. IxLoad can be configured to ramp traffic up/down in a custom fashion during a test, to simulate real world traffic patterns. To assist in estimating required resources, IxLoad analyzes its setup, and based upon traffic requirements, it calculates the number of Load Modules needed to execute a given test. To further test real-world scenarios, IxLoad can individually specify TCP parameters for the networks emulated in the test. Test Results IxLoad features a rich set of statistics that can be published in real time during test execution. The application is integrated with Ixia s highly customizable Stat viewer. The test results can be displayed in both graphical and tabular format, and can be customized by the user to highlight data of interest. Also, results are stored in PDF and CSV files for post-test viewing.
