Objects of this class specify traffic parameters. When the 'gen' method is invoked, returns a number dependent on the time since the last invocation and on the defined parameters. The number increases constantly to represent an SNMP counter.
e.g.:
use Net::Raddle::TrafficGen;
my $IFBytesIN = Net::Raddle::TrafficGen->new( {rate => 100000/8} )
or die "cannot create traffic generator";
print "We have seen ", $IFBytesIN->gen(), " bytes since boot\n";
sleep 5;
print "We have seen ", $IFBytesIN->gen(), " bytes since boot\n";
sleep 5;
print "We have seen ", $IFBytesIN->gen(), " bytes since boot\n";
TrafficGen will throw an exception using die if the parameters are not understood.
When used with Net::Raddle::SNMPAgent statements like this will work:
$agent->TieMIBItem( CanonicalOID('IF-MIB::ifInOctets.102'),
ASN_COUNTER, Net::Raddle::TrafficGen->new( {rate => 123000000/8, limit => 155000000/8} );
Any request for IF-MIB::ifInOctets.102 will now return a number of bytes that increases in a semi-random manner, with a maximum bandwidth of 155Mbit/s
new()The new() method creates an object of class Net::Raddle::TrafficGen and sets config parameters.
The parameters are passed as a pointer to a hash, whose keys may include:
