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

摘要

Disclosed is a buffer management method for generating and releasing a storage space of a buffer for storing transmission/reception data in a communication system. The buffer management method is a descriptor pool and a memory block pool existing in a physical memory area, and a plurality of descriptors are previously allocated to the descriptor pool, and a plurality of memory blocks are allocated to the descriptor pool. Pre-allocating to the memory block pool; Receiving one descriptor from the descriptor pool and a predetermined number of memory blocks from the memory block pool; And creating a storage space of the buffer by connecting the descriptor and the predetermined number of memory blocks in a linked list structure.
