Communication apparatus and communication control program

摘要

A communication apparatus has an upper-layer evaluation parameter acquisition part configured to acquire an evaluation parameter for an upper-side layer among a plurality of layers included in a network, a fragment-size decision part configured to decide a fragment size to be used in dividing a packet that includes information of an upper-side layer into fragments, based on the evaluation parameter acquired by the upper-layer evaluation parameter acquisition part, and a fragment controller configured to divide the packet into a plurality of fragments based on the fragment size.

1. A communication apparatus comprising:
an upper-layer evaluation parameter acquisition part to acquire an evaluation parameter for an upper-side layer among a plurality of layers included in a network; a lower-layer evaluation parameter acquisition part to acquire an evaluation parameter for a layer lower than the upper-side layer among the plurality of layers; a fragment-size decision part to decide a fragment size to be used in dividing a packet that includes information of an upper-side layer into fragments, based on the evaluation parameter acquired by the upper-layer evaluation parameter acquisition part and the lower-layer evaluation parameter acquisition part; and a fragment controller to divide the packet into a plurality of fragments based on the fragment size, wherein the evaluation parameter acquired by the lower-layer evaluation parameter acquisition part includes at least one of a bit error rate, a channel busy rate, an average fragmented-packet transmission count and a cumulatively added value of an average value of a fragmented-packet transmission count.
