三层虚拟覆盖网方案的数据平面技术研究

With the current scale and business network expanding, providing support and service functions of the data center is facing more pressure and challenge. The network virtualization technology applies to the data center will effectively relieve the current performance bottleneck of data center. In order to expand the scope of application of network virtualization technology, IETF builds NVO3 working group and researches the construction of virtual network based IP network. For that, Huawei company in NVO3 framework of IETF,proposes ISIS-NVO3 network virtualization solution and analysises the functions and goals of control plane.This paper analysises the structure model, proposes the realization mechanism of the data plane based on the functions and goals of control plane of ISIS-NVO3 network virtualization solution, perfects the whole solution and lays the foundation for the realization of the solution.
