7.24 E1000 Network Adapter Device
The network adapter device models an Intel Pro/1000 MT Desktop Network Adapter. The adapter depends heavily on MAC address assignment in order to determine how visible it is to real network resources or other simulator network sessions. The adapter model requires a separate mediator process to bridge access to the real network. This device provides a list of automation commands that can be used to configure the adapter model, see Section A.7, “Automation Commands”, on page 227.
To model network workloads the following are typically required:
1.One or more BSDs with a NIC device included in each BSD.
2.A mediator process running remotely or locally.
The mediator is a background daemon task, whose purpose is to bridge the NIC model to the real network or other SimNow BSDs. The level of network visibility for each simulator session depends on the format of the MAC address that is used for the simulated NIC model.
Figure 7-32 shows depicts four simulator sessions communicating via a mediator.
