IPvXTrafGen

simple module

Sends IP or IPv6 datagrams to the given address at the given sendInterval. The sendInterval can be a constant or a random value (e.g. exponential(1)). If the destAddresses parameter contains more than one address, one of them is randomly for each packet. An address may be given in the dotted decimal notation (or, for IPv6, in the usual notation with colons), or with the module name. (The L3AddressResolver class is used to resolve the address.) To disable the model, set destAddresses to "".

The peer can be IPvXTrafSink or another IPvXTrafGen (it handles received packets exactly like IPvXTrafSink).

The following diagram shows inheritance relationships for this type. Unresolved types are missing from the diagram.
