46 node acts as a source of packets according to the parameters set up
50 node type is used primarily for testing and benchmarking.
54 node has two hooks:
60 hook must remain connected, its disconnection will shutdown the node.
62 The operation of the node is as follows.
70 node assumes that its neighbour node is of
72 node type.
73 The neighbour is queried for its interface name.
76 node then uses queue of the interface for its evil purposes.
79 node also disables
83 node.
84 If interface name cannot be obtained automatically, it should
91 node manually.
93 If the node is connected to a netgraph network, which does not
96 interface, limit the packet injection rate explicitly with the
102 control message the node starts sending
106 as the connected interface will take them.
107 While active, on every clock tick the node checks the available space
108 in the interface queue and sends that many packets out its
114 message, the node stops sending data.
116 This node type supports the generic control messages as well as the following,
120 .Bl -tag -width foo
123 .Bl -tag -width ".Va elapsedTime"
147 .Va endTime Li \- Va startTime
