IxLoad: Overview
IxLoad is a scalable solution for testing converged multiplay services and application delivery platforms. IxLoad emulates data, voice, and video subscribers and associated protocols for performance testing.
Its unique and advanced subscriber modeling capabilities create realistic scenarios to validate subscriber quality of experience (QoE). Protocols supported include video protocols like MPEG, IGMP, and RTSP; voice protocols like SIP, H.323, H.248, SCCP and MGCP; and data protocols like HTTP, P2P, FTP, and SMTP. In addition, IxLoad can be used to test critical aspects of the infrastructure like DNS, DHCP, and AAA services. Security platforms can be tested with integrated L2/L3 authentication mechanisms such as 802.1x and NAC, as well as malicious traffic to test for vulnerabilities.
IxLoad works with Ixia’s test platform to transmit and receive control and data traffic with the device under test. Ixia’s chassis are populated with hot-swappable test interface cards that implement a wide variety of Ethernet, POS and other technologies. Each test port is equipped with an independent processor and substantial memory in addition to specialized traffic stream generation and capture hardware – providing the speed and intelligence needed for large-scale protocol emulation.
IxLoad/VM is designed to work in virtualized environments using Ixia’s unique virtual chassis implementation. The IxVM virtual chassis is a software implementation of Ixia’s platform allowing virtual machines (VMs) on blade servers to act as Ixia test ports. The virtual test ports can be used independently or in conjunction with chassis based ports. Software-based stream and protocol engines in the virtual chassis ports provide the same traffic generation and analysis as Ixia’s hardware-based product portfolio.
