MEMORY MANAGEMENT METHOD AND SYSTEM IN NETWORK PROCESSING SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a method and a system for managing a memory in a network processing system for providing the allocation of a physical memory section inside a network processor connected to a control point processor by a bus. SOLUTION: This allocation system provides a memory management layer without the need of a complete operating system interface and supports the asynchronous completion of allocation requests. Multicast allocation is supported and the allocation can be simultaneously requested on the plural network processors. An allocation mechanism returns a token, then a memory position is accessed by a protocol through the bus by using the token, and the allocation performed on the plural network processors where actual physical addresses and memory constitution are different is referred to by a single token.
