How accurate is the SNE?
Panel | ||
---|---|---|
| ||
The timing precision is 10 microseconds (0.01ms). |
How much delay can be added?
Panel | ||
---|---|---|
| ||
The emulator can add from 0.01ms to 4secs of latency on 25G and 10G interfaces. The max delay is 4secs TOTAL. A bi-directional link is 2sec max in each direction |
Do you support Layer1 impairments (e.g. BER, Symbol errors)?
Panel | ||
---|---|---|
| ||
The Emulator supports BER but not Symbol Errors. |
How many module slots are available?
Panel | ||
---|---|---|
| ||
There are 4 slots in the chassis. Network cards are fitted at the factory and are not user-swappable. |
How many ports per module are there?
Panel | ||
---|---|---|
| ||
100GbE: 2 ports per module. 25GbE: 2 ports per module. 10GbE: For STD (standard) cards you can have 2 2 ports per module. For the HPC (High Port Count) cards you can have 4 ports per module. 1GbE: 4 ports per module. |
Can I have a mixture of 1GbE, 10GbE, 25GbE and 100GbE modules in the same chassis?
Panel | ||
---|---|---|
| ||
Yes, but you cannot mix 25GbE cards and the 10GbE HPC cards (10GbE STD cards are allowed). You also cannot mix 10GbE STD and 10GbE HPC cards in the same chassis. |
I have a 1GbE fibre connection. How can I get the 10GbE ports to auto negotiate to these speeds?
Panel | ||
---|---|---|
| ||
The 25GbE and 10GbE ports do not auto-negotiate and when the SNE is powered on both sets of modules will run at their highest rated speed. To force a re-negotiation you can right-click on a network start or end point and select Reset all Ports (version 7 software or earlier) or select the ports from the Dashboard and click Reset Ports (versions later than v7). |
Does the SNE support Ethernet fragmentation?
Panel | ||
---|---|---|
| ||
Yes. |
Does the SNE have its own background traffic generator?
Panel | ||
---|---|---|
| ||
Yes. You can generate either UDP (using the Background Traffic Generator) or TCP packets (using the TCP Server Generator). |
Does the SNE have a visual GUI?
Panel | ||
---|---|---|
| ||
Yes, this is a key value of the SNE. The GUI displays a graphical visual network which makes it very easy to build complex networks. From version 11.x of the SNE firmware onwards, the user interface is accessed from a standard web browser (this interface is referred to as the "Web UI"). |
Does SNE support duplicating?
Panel | ||
---|---|---|
| ||
Yes, we support duplicating of packets. You can either duplicate packets using a dedicated Duplicator tool (specifying 1:1, 1:X or 1:X with a delay between duplicates) or you can simply draw two links from an Input Port to duplicate the traffic from that port. This could be used to achieve a similar effect to port mirroring, if desired. |
Does SNE support ToS filtering?
Panel | ||
---|---|---|
| ||
Yes, ToS filtering is supported - we support DSCP in a dedicated filter, but can provide any ToS filtering through a generic filter. |
Can you delay a particular class of traffic? Example: Delay only TCP traffic with particular destination or delay VoIP Traffic
Panel | ||
---|---|---|
| ||
Yes, filters can be used to identify any type of data. Once a filter has "passed" or "failed" a certain type of traffic, you are free to apply any type of impairment to that stream. |
Does SNE support delaying Audio from Video? Example: Delay only Audio from Video traffic
Panel | ||
---|---|---|
| ||
Delaying audio from video depends on the structure of the AV stream. There are likely to be two ways the AV stream is encoded:
