The main differences between the Virtual SNE (vSNE) and the physical SNE are summarised in the table below.
| SNE | Virtual SNE |
|---|---|---|
Port density | Up to 16 ports of 10GbE. Up to 8 ports of 100GbE. | 2 ports per instance. |
Interfaces/data rates | 1/10/25/50/100GbE. Possible to span 1GbE – 100GbE in a single chassis by fitting the appropriate cards. | 1/10/25/50GbE Up to 50Gbps in a single instance. |
Any port to any port traffic routing | Yes. Can send traffic between all licensed ports, even between ports of different rates. | Not applicable. Point to point emulation only, as only two ports available. |
Toolkit | Full range of 55+ impairments, filters and other tooling available. | Reduced toolkit for impairments and filtering. Available impairments are delay, jitter and packet loss. |
Network modelling | Can create dynamic network models via SNE Timeline feature and CSV file upload. | Not applicable. Timeline feature not included in vSNE. |
Hardware requirements | Purpose built, highly performant dedicated hardware. | Requires high specification server. Runs in VMware (ESXi) only. |
