Managing network resources by using datalink properties improves the system's efficiency in processing packets. You can set datalink properties when you create the link. Alternatively, you can set datalink properties later, for example, after studying resource usage over time and determining how to better allocate the resource. By setting datalink properties that pertain to network resources, you can decide how much of a given resource can be used for the networking processes. The procedures for allocating resources apply to the virtual network as well as the physical network. For more information about datalink properties and how to configure them, see Managing Network Resources by Using Datalink Properties.
