Buffer management is the strategy for deciding when and how to discard packets to avoid network congestion. Its performance can be measured in terms of its ability to control traffic fairly and efficiently during periods of congestion. Typically, packet discard decisions are made either upon the arrival of a new packet, or at the onset of congestion, when currently stored packets may be discarded to accommodate a new, higher‐priority packet. Chapter 6 describes some buffer management mechanisms for ATM networks and the Internet, respectively.
