Abstract
A system and method comprise a first buffer having a first capacity and a first threshold level adapted to store data frames having the lowest priority, a second buffer having a second capacity greater than the first capacity and a second threshold level greater than the first threshold level adapted to store data frames having a medium priority, a third buffer having a third capacity greater than the second capacity and a third threshold level greater than the second threshold level adapted to store data frames having the highest priority. The system further includes means for differentiating a data frame as having lowest, medium or highest priority and storing the data frame in the respective first, second or third buffer, and discarding the data frame in response to the first, second or third buffer reaching the respective threshold level.
