Integrated L2-7 Solution
The Agilent N2X brings unique integration to the market in two key ways.
- Only the N2X integrates both L2-3 and L4-7 testing on the same software application running simultaneously on the same physical interface. Unlike solutions which are on separate hardware platforms, or perhaps a common hardware platform but mutually exclusive software applications, the Agilent N2X brings L2-3 testing and L4-7 testing conveniently together on the same physical port, and in the same integrated software application.
- Only the N2X provides tightly integrated stateful and stateless traffic generation and measurement in the same test solution. With 32K streams and flexible PDU definitions, the N2X has provided powerful and flexible traffic generation and analysis for several years. With the addition of a highly-scalable stateful traffic and measurement solution to the Packets and Protocols application, N2X users now have access to two traffic and analysis models uniqueluy integrated into the same software application and running simultaneously on the same physical interface.
Stateful TCP: Re-defining Traffic Blasting and Measurement at Layer 4
N2X’s stateful TCP traffic model provides unprecedented scalability and flexibility to quickly find the non-drop rate of forwarding devices in the presence of stateful traffic. N2X is the only solution that offers a dynamic traffic load ‘slider bar’ that allows users to immediately adjust traffic load on the fly and quickly saturate a gigabit Ethernet pipe, even with very short (< 1000 bytes) packets! By comparison, CPU-based solutions require the user to completely stop a session, set a new bandwidth level, and then re-start traffic – a tedious and time-consuming process. Further CPU-based solutions typically cannot saturate traffic at gigabit Ethernet rates unless several ports are ganged together, increasing cost and complexity.
Key Features
- Characterize L4 forwarding performance with “Connection Blasting”
- Load a GbE pipe with stateful TCP traffic at line rate
- Emulate a fully-featured TCP stack: fast
retransmit, slow start, congestion avoidance
- Higher-layer application traffic over active TCP connections
- Real-time goodput measurements on TCP traffic
- Integrated on same physical interface and software application as stateless N2X traffic
