Szukana fraza: [Abstract = "A packet buffer limited to a fixed number of packets \(regardless of their lengths\) is considered. The buffer is described as a finite FIFO queuing system fed by a Markovian Arrival Process \(MAP\) with service times forming a Semi\-Markov \(SM\) process \(MAP\/SM\/1\/b in Kendall`s notation\). Such assumptions allow us to obtain new analytical results for the queuing characteristics of the buffer."]
