Memory is a limited resource in communication devices. While communication, computation and memory capabilities continuously increase, with the advance of standards and systems such as 3G and broadband wireless MAN, there is also a substantial increase in the demand for bandwidth and memory. For example, a typical WiMax base station is supposed to serve a metropolitan area with hundreds of users demanding high speed multimedia applications. With a limited memory space, buffer management is necessary for maximum performance in such a multiuser system. Sharing limited buffer space among multiple packet streams is a problem that previously attracted interest in the context of shared-memory switches and wireline networks.
