Provided are a virtual network realization method, NVE and NVA device and system. The method comprises: establishing a TCP connection between a network virtualization edge (NVE) and a network virtualization authority (NVA), and running a virtual network transport protocol (VNTP) on the TCP connection; the NVE transmits routing update information of the VN to the NVA via the VNTP; and the VNA forwards the routing update information of the VN to all the other NVEs thereof, thus solving the problem of higher requirements and complicated protocol on the virtual network realization, and lowering the realization condition of the virtual network. |
