IP Network Application ( IP Routing and Switching Testing )

As networks converge into a single network infrastructure that is used to carry voice, video, data, and wireless traffic, it is critical to use leading-edge test systems to assess functionality, scale, and performance. IxNetwork provides wire-rate traffic generation with service modeling that builds realistic, dynamically-controllable data-plane traffic.

IxNetwork offers the industry’s best test solution for functional and performance testing by using comprehensive emulation for routing, switching, multi-protocol label switching (MPLS), IP multicast, broadband, authentication, Carrier Ethernet, and data center bridging (DCB) protocols. IxNetwork scales to handle the most powerful devices and largest networks.

IxNetwork offers the customization and flexibility to meet the wide range of requirements necessary for testing complex network topologies with thousands of network devices. It emulates millions of routes and reachable hosts and can customize millions of traffic flows to stress data plane performance. Powerful graphical user interface (GUI) wizards and grid controls allow simplified creation of sophisticated traffic flows. Its enhanced real-time analysis and statistics are capable of reporting comprehensive protocol status and detailed per-flow traffic performance metrics.

IxNetwork emulates a wide variety of protocols using Ixia's CPU-based test port. Each test port supports an independent PowerPC CPU running protocol emulations under a Linux operating system. Using the IxNetwork test application, each Ixia test port is capable of emulating thousands of routers or bridges with millions of reachable networks and hosts. Users can easily scale the size of emulated topologies by adding additional test ports.

Combined with line-rate traffic generation and QoS measurement capabilities, the CPU-based load modules verify advertised topologies and networks for reachability and QoS performance.

Below shows the supported protocols in IxNetwork :

Key Features

• Innovative Next-Generation Protocol Framework that enables:
o Fast and efficient configuration of network emulation
o Single view of entire network state across all configured ports and protocols
o Graphical navigation to drill down into statistics per protocol
o Color-coded representation of protocol state per-topology and per-device,

along with associated statistics, for quick understanding of network state

o Subset of protocols included in initial phase of the framework (see following

tables)
o Legacy workflow configuration supported

• Easy-to-use protocol and traffic wizards emulate complex networks with the widest

selection of layer 2 (L2) and L3 protocols and traffic profiles

• Dynamic traffic support, with the ability to change rate and frame size on the fly,

and dynamically-updated MPLS and PPP traffic without stopping and restarting

• Advanced measurements, including four latency modes, delay variation (jitter),

inter-arrival time, sequence checking, misdirected packets, packet loss duration, and

Rx rates

• Streamlined workflow that exposes all configuration options in context-sensitive

ribbons and contains an overview summary of ports, protocols, and traffic with

detailed views

• Collaborative resource management with Resource Manager - divide and conquer

large, complex test topologies, compare resource versions and configuration

changes, merge resources with easy-to-use wizards

• Statistics viewer providing summary-level, group-level, and per-flow statistics with

sophisticated results filtering and sorting powered by Flow Detective™, enabling

real-time analysis

• Virtual server and cloud testing through virtual test ports

• Quickly and easily record interactions with IxNetwork and save these recordings as tests

for later use with Macro Recorder

• Multi-field ingress tracking to track flows based on multiple user-defined fields

• Multi-egress tracking provides a unique ingress/egress results view that compares sent

traffic with received traffic, so as to accurately verify what DUT packet field

modifications; QoS remarking is easily verified

• Ability to add custom formulas in any statistics view

• Powerful reporting with one-click report generation, data analysis, custom report and

template builds, customizable charts and graphs, in PDF or HTML formats

• QuickTests for industry-standard test methodologies, including RFCs 2544, 2889, and

3918, and ITU-T Y.1564

• Easy one-click TCL, HLTAPI, or HLPAPI automation using ScriptGen, with complete API

support – providing complete automation of IxNetwork functions
