摘　　要：网络中核心设备的数据吞吐量非常大,兼顾高数据量吞吐和业务处理非常重要。提出采用最新的多核多线程处理器,以VCPU为单位部署操作系统,实现两种操作系统共CORE,通过共享内存通信方案,有效解决高数据吞吐率和复杂业务处理的矛盾,细化多核处理器的分配粒度,从而提升网络核心设备的性能。The core network devices have very large network throughout, so it＇s very important to balance the high volume of data throughout and the complicated service process.This paper proposes a scheme that adopts multi-core and multithreaded processors,takes VCPU as unit to deploy operating system （OS）,two different operating systems communicate with each other with shared memory.Through sharing one core effectively solves this contradiction.h helps to achieve an efficient deployment of VCPUS in muhi-porcessors and significantly improve performance of the core network devices.
