Overview
The Calnex SNE is a multi-port, multi-user network emulator and simulator used to reproduce real-world network conditions in the lab, so that applications and infrastructure can be tested before deployment. It supports 100GbE, 50GbE, 25GbE, 10GbE and 1GbE interfaces in a 2U rack chassis with four slots for interface cards, which can be mixed to suit the required port count and rates.
Network emulation and simulation
The SNE provides common impairments such as delay, jitter and bandwidth throttling as well as advanced impairments including packet fragmentation, video corruption, BER corruption, reordering, duplication and loss models. Packets can be sent between any port and any other port, and multiple paths can be modelled and switched in real time to simulate back-up circuits and switchovers. A 5G dataset modelled from carrier data is available for testing applications under common 5G conditions.
User interface and automation
The instrument is controlled from a web browser through a Web UI, in which users build network "maps" by dragging impairments onto a canvas and linking them in the required order. A dashboard view shows port configuration, link status and port allocation per user. Automation is available through a RESTful API and through the Timeline (auto-change) feature, which schedules changes to emulation settings from the Web UI without scripting.
Multi-user operation and analysis
Each user can be allocated a pair of ports or a group of ports for exclusive use, allowing a single unit to be shared by a team. Built-in filters target specific traffic streams, load generators and PCAP replay add background traffic, and Wireshark integration supports live capture and root cause analysis.
