Abstract
A method and system for memory management in a network processing system provides for allocation of physical memory areas within network processors coupled to a control point processor by a bus. The allocation scheme provides a memory management layer without requiring a complete operating system interface and supports asynchronous completion of the allocation requests. Multicast allocation is supported allowing an allocation to be simultaneously requested on multiple network processors. The allocation mechanism returns a token, which may then be used to access the memory location via a protocol over the bus, and a single token may refer to an allocation made on several network processors where the actual physical addresses and memory configurations are different.
