Abstract: According to the problem in the transitional period of IPv4/ IPv6 and the shortages of the mainly techniques during this period, this paper proposed the IPv6 tunnel technology based on multi-core, designed its model, used the multi-core flow technology, the lock-technique and the multi-core loadshare model to speed up transmitting, protected the critical resources and improved the whole performance. Finally, the IPv6 tunnel technology based on multi-core is proved to have better transition and service performance than that based on singlecore.

Key words: multi-core, IPv6 transition technology, IPv6 tunnel technology

摘要： 针对目前IPv4/IPv6过渡时期存在的问题，结合目前主要过渡技术的不足，提出基于多核的IPv6隧道技术，设计了多核下IPv6隧道模型。利用多核流技术、锁技术和多核负载分担方法，加速转发处理、保护多核临界资源和提高系统整体性能。仿真实验结果表明，IPv6隧道技术基于多核比基于单核的实现，在转发与处理性能上成倍提高，能更好地解决过渡时期存在的问题与适应未来的发展。
