网络存储架构需要一个高可靠性和高可用性的后端存储服务器来提供网络存储服务，而单网口配置制约了服务器数据传输性能。目前Linux内核bonding技术已经实现了将多个物理网口聚合为一个单一虚拟网口的方法。但这种不对称的技术在实现接收数据负载均衡时，只是通过ARP协商机制实现静态分配多网口，因此在实际应用中存在性能上的缺陷。鉴于此，在对现有的相关技术和算法进行研究后，提出了另外一种在此基础上改进的算法，即基于适应性负载均衡的动态接收算法，利用netfilter等技术对此算法进行了实现，进行了实际测试验证。新算法能显著提高多网口服务器接收数据时网络传输吞吐率。

Network storage architecture requires a high reliability and high availability back-end storage server to provide net-work storage services, but the single Ethernet port configuration restricts the server data transfer performance. Linux kernel bonding technology has realized multiple physical network ports aggregate to a single virtual network port. But when receiving data, this technology just through the ARP consultation mechanism realizes statically distributing multiple network port, therefore performance defects exist in the practical. In view of this, after researching related technology and algorithm, this paper puts for-ward another improved algorithm, which is based on adaptive load balance dynamic receiving algorithm, and realizes this algo-rithm by netfilter technology and so on. The actual test verification is done. The new algorithm can significantly improve the multiple network port server transfer throughput rate while receiving data.
