A buffer management method for efficiently processing transmission and reception data and communication system

摘要

A buffer management method for creating and releasing a storage space of a buffer for storing transmission/reception data in a communication system is disclosed. In the buffer management method, as a descriptor pool and a memory block pool existing in a physical memory area, a plurality of descriptors are allocated in advance to the descriptor pool, and the plurality of memory blocks are allocated to the pre-allocating a memory block pool; receiving one descriptor from the descriptor pool and receiving a predetermined number of memory blocks from the memory block pool; and creating a storage space of the buffer by connecting the one descriptor and the predetermined number of memory blocks in a linked list structure.
