Defining Traffic with N2X
The Agilent N2X helps you build up real-world network traffic scenarios in just a few simple steps.
Defining traffic is an essential part of the network equipment testing process. Network equipment manufacturers should measure the performance of their products by testing traffic forwarding, policing, and QoS with different protocol encapsulations. Service providers select network equipment by testing them under rigorous conditions. With a test tool that defines realistic traffic, discovering the weaknesses of network equipment is much easier.
The rising number of protocols and the increasing complexity of network traffic require easy, realistic and flexible ways to define traffic. The Agilent N2X is capable of generating a traffic load and variety that resemble real-world scenarios, and it has many easy-to-use features that help improve and accelerate test processes.
N2X enables users to build multi-layer Protocol Data Units (PDUs) from
a wide range of predefined protocols, or even write their own proprietary protocols with Extensible Markup Language (XML), to perform a test. While the traffic is running, you can observe real-time measurements on a per port, per stream, or per field basis. The N2X’s PDU Builder is a flexible software tool for creating PDUs. A key feature is that it can easily generate a series of values by applying a modifier to certain fields, such as specifying a range of IP addresses.
