负载均衡是云计算的基本问题之一,多核环境中多进程负载均衡会话保持问题得到广泛关注并发展成为研究热点.针对该问题,面向Linux内核,基于Hash化管理内核网络数据包传递的思想,该文提出并实现了一种无锁的多进程负载均衡会话保持方案.该方案避免了锁的使用,而且不需要对原有单进程负载均衡程序进行结构上的修改,能够快速地将现有单进程负载均衡程序转变为多进程架构.理论分析和实验表明,相较于传统的共享内存式锁机制会话保持解决方案,该方案性能更好、适用性更强,提高了多核环境中负载均衡系统的效率.

@@@@Load balancing is a fundamental problem for cloud computing, multi-processing load balancing session persistence in multi-core environment have drawn more attention and have become a focus. For the issue, based on the idea of Hash Linux kernel network data packets passing, a lock-free multi-processing load balancing architecture is proposed, which avoids the use of locks, and can quickly change the existing single-processing load balancing procedure for multi-processing architecture without structural changes. The theory analysis and experimental results show that the proposed architecture is able to improve the overall performance of load balancing system in multi-core environment. Compared with the traditional shared memory architecture, the proposed is able to get better performance and has stronger applicability.
