Effect of fragmentation threshold:Fraglnentation
threshold Specifies the value to decide if the MSDU received from the higher layer needs fragmentation before
transmission.The number of fragments to be transmitted
is calculated based on the MSDU size and the
fragmentation threshold The default value for this
attribute is none which means that fragmentation will not
take place regardless of the MSDU size.The destination
station receives these fragments and store them in the
reassembly buffer until all fragments have been received
This fragmentation and reassembly is implemented using
the built-in SAR(segmentation and reassembly)package
in OPNET.

分散阈值的作用:分散阈值指定一个值,该值决定从上层收到的数据单元在传输前是否需要分片.传输前需要分片的数目是基于数据单元的大小和分散阈值来计算的.该属性的默认值是none,none表示不管服务数据单元多大,分片操作都不会进行.目的站收到这些分片并存储到重组缓冲区中直到所有的分片都收到.这种分片和重组的行为通过OPNET内置的分片重组包来实现.
