IxANVL™: IP Test Suite - Ixia

DATA SHEETIxANVL: IP Test SuiteConformance testing is required to validate that networking devices arecompliant with existing standards. This ensures that devices not only supportknown protocol features correctly, but also that devices will be able tointeroperate with other devices in the network.Ixia's IxANVL (Automated Network Validation Library) is the industrystandard for automated network/protocol validation. Developers andmanufacturers of networking equipment and Internet devices rely on IxANVLto validate protocol compliance and interoperability. Many customers havechosen IxANVL for its ease-of-use, enhanced GUI, and flexible testautomation capabilities. In addition, IxANVL offers a veritable universe ofprotocol libraries and utilities.IxANVL has several test suites that cover various networking technologiesand protocols. IxANVL’s IP test suite covers conformance testing for DHCP(client and server), ICMP, and IPv4. An example test topology for IPv4 isshown in the figure below:Figure 1: Two interface IPv4 testBenefitsIxANVL Saves Time & MoneyIxANVL allows vendors to verifythe design during their product’sentire life cycle.

DATA SHEETThis topology simulates HOSTs to router communication between the DUT and ANVL. Here the DUT is a routerand ANVL simulates two HOSTs. Two separate networks are represented by N0 and N1.An example of a DHCP server test topology is shown in Figure 2:Figure 2: Three simulated DHCP clients testing a single server interfaceIn this topology, ANVL simulates three DHCP clients connected to the DUT through belonging tonetwork N0. All of these clients are connected to the same DUT interface through an emulated broadcast device(for example, a hub).Page 2

DATA SHEET• Prioritize and group TALs for the test suite• Develop a test method for each accepted test assertionIxANVL performs continual verification of protocol standard authors or implementers during the developmentprocess.Test ConfigurationThe IxANVL test suite can run on a Linux or Windows PC with off-the-shelf network interface cards, or on Ixia'sload modules through a virtual network interface card (VNIC) connection. The tester (PC) connects with the DUTvia test interfaces. Up to four interfaces may be used, depending on the test configuration. IxANVL flexiblyemulates various system topologies, and creates virtually any test scenarios for almost any DUT.IxANVL offers both a command-line interface for test automation and a user-friendly graphical user interface,allowing intuitive test execution management and detail reporting. A batch runner is also available for schedulingregression test-run sequences.Test ExecutionIxANVL classifies test cases into three categories: MUST, SHOULD, and MAY. Tests can be selceted andexecuted based on their categories or test topologies.The IxANVL test can be run using two options - GUI or command line input. In GUI mode, the user selects whichtest suite and test cases to run. In command line mode, the user types a command with options indicating whichtests should run and the desired output level.In the test, IxANVL sends packets to the DUT based on the test designed, and compares the received DUTpackets to what was expected. After receiving these packets, IxANVL reacts according to the returned information- it may continue the test, stop the test, log an error message, or a host of other functions.During the test, IxANVL logs the progress in real-time. After completion, IxANVL indicates whether the testpassed or failed. IxANVL then repeats the process with the next test until all selected tests have been run.PlatformAn IxANVL workstation supports the following configuration:• CentOS 5.3 (kernel 2.6.18-128.e15xen); Redhat Enterpise 4.0 with kernel 2.6.9-11 or 2.6.22.0.2.EL; RedhatEnterprise 5.0 (with kernel 2.6.18-53.el5)• Microsoft Windows XP Professional or Windows 2003 Server (US English versions)• 1.5 GHz Pentium CPU or faster (32 bit system only)• 1 GB RAMPage 6
