Если поделить разницу на число переданных пакетов, получается в среднем
17,3 байта на пакет.
Скорее всего, разница в подсчёте заголовков пакетов (например,
заголовков кадров PPP - хотя они меньше). Могут быть также
несоответствия по поводу учёта сжатия заголовков TCP (VJ compression) -
на это больше похоже.
