And the packet loss goes down to 10-9 and 10-6 separately when the wavelength converter number are 1/3 and 1/4 of the total port number of the switching. The packet loss of the LAUC-VF algorithm under nonbursty and bursty traffic is simulated.

• 首先无波长变换器时系统的丢包率非常高达10-1以上,而当波长变换器的数量为系统总信道数的1/4左右时,由于波长竞争而导致的丢包率可以达到10-6以下,当波长变换器的数量为系统总信道数的1/3左右时,由于波长竞争而导致的丢包率可以达到10-9以下。
