The Network Host emulator is used to simulate one or more application servers in a public or private network.
A Network Host is defined in:
The Data Traffic tab of a data-capable nodal test cases. The Network Host Node is also available in LNS Node test case.
The Network Host pane on the Network Host Emulator Configuration in the Network Host test case.
When Dual Stack is selected, the Network Host operates concurrent IPv4 and IPv6 stacks. The two concurrent IPv4 and IPv6 nodes must be configured with the details described below: number of nodes, IP address, routing options, and port selection.
|
NOTE:Both the IPv4 and IPv6 nodes must use the same physical interface and be configured with the same number of nodes or a an error occurs. This does not affect the remote network host configuration. |
Number of Client IP Addresses indicates the maximum number of client IP address supported by the node. Tcl Parameter : NumIpAddr
Tcl Parameter: NetworkHostAddrLocal
With an Network Host node, you can define:
Up to 1000 Network Host nodes with the Number of Nodes parameter in a Continuous data test. When you provision multiple nodes, the Starting IP Address will be sequentially incremented for each node and you can select which DMFs will be executed against a particular node with the Assignments tab on the Data Traffic Tab | Data Profiles pane.
|
Important: The network host should have a Next Hop Ip Address or static route provisioned in order to properly route packets without impacting performance. |
|
NOTE:
|
|
TIP: Provision 4 Network Host test cases each with 1 Node and 1 DMF (on the Server side), for testing the Enhanced L4-L7 flows. |
Custom port selection... and error injection with the Advanced... button.
The L3, L4 L5-7 report tabs displays the Data Traffic measurements for the node.
