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.
- Downloading a network profile from the NV Server, as described in Download Network Profiles from the NV Server.
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]|
|3G poor - intercontinental||175||0.1||2000||500|
|3G typical - intercontinental||115||0||8000||3000|
|4G poor - intercontinental||150||0.1||3000||1000|
|4G typical - intercontinental||90||0||20000||6000|
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.
