摘要
用户级通信允许应用程序直接访问网络接口,减少了通信层次的软件开销。为了支持用户级通信,高效的虚拟地址到物理地址的转换起到关键作用。通过对几种地址转换方法的比较,提出了用户级操作的地址转换法。并用其对虚拟接口高性能模块的实现(M-VIA)进行了改进。实验证明用户级操作的地址转换法具有更好的通信性能。
User - Level communication alleviate the software overhead of the communication subsystem by allowing application to access the network interface directly. For this purpose, efficient virtual - to - physical address translation is critical. By comparing with some kinds of address translations, we propose the theory of user - managed TLB（ translation lookaside buffer） and improve M - VIA with it. Finally, performances of proposed method are demonstrated by the experiment.
