示例1: handle_packet
# 需要导入模块: from src.sim import Sim [as 别名]
# 或者: from src.sim.Sim import trace_custom [as 别名]
def handle_packet(self,packet):
# handle ACK (Sender)
# if the ACK number is greater than our send base...
# update the acknowledged segment counter, restart timer and send if possible
if packet.ack_number > self.send_base:
Sim.trace("ACK RCVD: %d <=== %d : %d" % (packet.destination_address,packet.source_address,packet.ack_number))
bytes_acked = packet.ack_number - self.send_base
self.not_yet_acknowledged_segments -= bytes_acked
if self.cwnd >= self.ssthreshold:
self.cwnd += (self.mss * bytes_acked) / self.cwnd
else:
self.cwnd += bytes_acked
self.cancel_timer()
self.timer = Sim.scheduler.add(delay=self.timeout, event='new_ack_data', handler=self.retransmit)
self.send_if_possible()
self.send_base = packet.ack_number
# print congestion window
if self.source_port > 3:
Sim.trace_custom("%f" % (self.cwnd/self.mss), 'cwnd', self.source_port)
# handle data (Receiver)
if packet.length > 0:
Sim.trace("SEGMENT RCVD: %d <=== %d : %d" % (packet.destination_address,packet.source_address,packet.sequence))
self.receive_temp_buffer.add(packet.sequence)
self.receive_packet_buffer.append(packet)
self.send_cumulative_ack()示例2: send_cumulative_ack
# 需要导入模块: from src.sim import Sim [as 别名]
