| 摘 要： | 为了避免创建缓冲区的过程中,由于多次释放和重新分配内存而导致可能的内存泄露和内存浪费等弊端,采用一种基于用户态的可自行调控的缓冲区管理机制,该管理机制是基于抽象缓冲区虚拟接口而设计的,具有自适应性,并且能够支持动态的内存分配、回收,缓冲区重用机制。研究结果表明:在基于零拷贝的集群并行通信系统中,采用该缓冲区管理机制的设计满足了网络通信系统的应用需求,该方法是一种高效的、可靠的、具有实时性的可兼容的缓冲区管理机制。

| Abstract: | To avoid the problem of memory leak and memory waste,which is caused by freeing and allocating memory,this paper proposes an automatic buffer management mechanism.The buffer management mechanism based on the abstract buffer has a good adaptive ability and supports dynamic memory allocation,recovery and reuse.The case study on the communication system with zero copy technology shows that the buffer management mechanism designed meets the requirements of a network communication system.In addition,it is highly... |
