◆ AssignStreams()

int64_t ns3::ApplicationHelper::AssignStreams ( NodeContainer c,
int64_t stream )

Assigns a unique (monotonically increasing) stream number to all applications that match the configured type of this application helper instance.

Return the number of streams (possibly zero) that have been assigned. The Install() method should have previously been called by the user.

Parameters
streamfirst stream index to use
cNodeContainer of the set of nodes for which the application should be modified to use a fixed stream
Returns
the number of stream indices assigned by this helper

◆ AssignStreamsToAllApps()

int64_t ns3::ApplicationHelper::AssignStreamsToAllApps ( NodeContainer c,
int64_t stream )
static

Assign a fixed random variable stream number to the random variables used by all the applications.

Return the number of streams (possibly zero) that have been assigned. The Install() method should have previously been called by the user.

Parameters
streamfirst stream index to use
cNodeContainer of the set of nodes for which their applications should be modified to use a fixed stream
Returns
the number of stream indices assigned by this helper

Install an application on the node configured with all the attributes set with SetAttribute.

Parameters
nodeThe node on which an application will be installed.
Returns
Ptr to the application installed.
