Abstract: A packet buffer stores packet data of packets received by a master device. The packet buffer includes a non-guaranteed buffer, a guaranteed buffer, and a reserved buffer. The non-guaranteed buffer is visible to the master device, and is not guaranteed to provide one free cell space for one cell in a first-type packet before the non-guaranteed buffer is full. The guaranteed buffer is visible to the master device, and is guaranteed to provide one free cell space for one cell in a second-type packet before the guaranteed buffer is full. The reserved buffer is invisible to the master device, and is arranged to provide headroom for the guaranteed buffer.
