Abstract: Memory management systems and methods that may be employed, for example, to provide efficient management of memory for network systems. The disclosed systems and methods may utilize a multi-layer queue management structure to manage buffer/cache memory in an integrated fashion. The disclosed systems and methods may be implemented as part of an information management system, such as a network processing system that is operable to process information communicated via a network environment, and that may include a network processor operable to process network-communicated information and a memory management system operable to reference the information based upon a connection status associated with the content.
