Traffic profile modules
=======================
The TRex STLProfile traffic profile includes a number of streams. The profile is a ``program`` of related streams.
Each stream can trigger another stream. Each stream can be named. For a full set of examples, see Manual_.
.. _Manual: ../trex_stateless.html
Example::
def create_stream (self):
# create a base packet and pad it to size
size = self.fsize - 4; # no FCS
base_pkt = Ether()/IP(src="16.0.0.1",dst="48.0.0.1")/UDP(dport=12,sport=1025)
base_pkt1 = Ether()/IP(src="16.0.0.2",dst="48.0.0.1")/UDP(dport=12,sport=1025)
base_pkt2 = Ether()/IP(src="16.0.0.3",dst="48.0.0.1")/UDP(dport=12,sport=1025)
pad = max(0, size - len(base_pkt)) * 'x'
return STLProfile( [ STLStream( isg = 1.0, # star in delay in usec
packet = STLPktBuilder(pkt = base_pkt/pad),
mode = STLTXCont( pps = 10),
),
STLStream( isg = 2.0,
packet = STLPktBuilder(pkt = base_pkt1/pad),
mode = STLTXCont( pps = 20),
),
STLStream( isg = 3.0,
packet = STLPktBuilder(pkt = base_pkt2/pad),
mode = STLTXCont( pps = 30)
)
]).get_streams()
