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.
