Network profile overview
You can use NV Test Manager to create and maintain network profiles. A network profile is a set of parameters that define network impairments and conditions. When you create a Quick Test, you can specify a network profile that contains the parameters to impose when the test runs.
What is included in a network profile?
Each network profile contains a list of network parameters. When a test is run, the parameters in the associated network profile are imposed on the network. The parameters in a network profile are:
Latency | The amount of time that it takes for an IP packet to travel across the network, from the client to the server, or from the server to a client. The actual network latency is the emulated latency plus any latency that exists in the actual network. The valid range is 0 to 8,000 msec. |
Packet Loss | The percentage of IP packets that are sent through the network, but do not reach their destination. The valid range is 0 to 100%. |
Bandwidth in | The maximum throughput through the network [in Kb per second], for data traveling from the server to the client. |
Bandwidth out | The maximum throughput through the network [in Kb per second], for data traveling from the client to the server. |
How do I create a network profile?
There are various methods that you can use to create a network profile, including:
- Specifying the parameters of a custom profile, as described in Create a custom network profile.
- Downloading the parameters from the NV Global Library, as described in Import network profiles from the NV Global Library.
What is a predefined network profile?
NV Test Manager is installed with a number of predefined network profiles. Each predefined network profile includes parameters that define a common network testing environment. You can select any one of these predefined profiles when you create a Quick Test. For details, see Create and run Quick Tests. You can view the predefined profiles and their parameters in the Profiles page on NV Test Manager.
Note: You cannot edit, delete, or rename a predefined profile.
For details on how to create a custom profile, see Create a custom network profile.
Predefined network profiles:
Profile Name | Latency [ms] | Packet Loss [%] | Bandwidth-in [kb/s] | Bandwidth-out [kb/s] |
---|---|---|---|---|
2.5G poor | 300 | 0.5 | 125 | 50 |
3G poor | 105 | 0.1 | 2000 | 500 |
3G poor - intercontinental | 175 | 0.1 | 2000 | 500 |
3G typical | 60 | 0 | 8000 | 3000 |
3G typical - intercontinental | 115 | 0 | 8000 | 3000 |
4G poor | 80 | 0.1 | 3000 | 1000 |
4G poor - intercontinental | 150 | 0.1 | 3000 | 1000 |
4G typical | 35 | 0 | 20000 | 6000 |
4G typical - intercontinental | 90 | 0 | 20000 | 6000 |
No emulation | 0 | 0 | unlimited | unlimited |
Network disconnection | 0 | 100 | 0 | 0 |
Can I use a network profile in an Advanced Test?
No, you can use a network profile in a Quick Test only. However, you can import a test configuration into an Advanced Test. A test configuration contains the parameters that specify the network conditions and constraints to apply when the test runs. For details, see Create and run Advanced Tests.
