The present invention provides a packet forwarding method and apparatus, and a data center network, and is applied in the field of communications. The data center network includes two tenant end systems, a local management function, and a network virtualization edge. The local management function sends, to the network virtualization edge, a packet to which a label is added and that is sent by a tenant end system, and the network virtualization edge determines, according to the label, a virtual overlay network identifier corresponding to the tenant end system, adds the virtual overlay network identifier to the packet, performs tunnel encapsulation on the packet to which the virtual overlay network identifier is added, and sends a packet that is after the tunnel encapsulation to another network virtualization edge. According to the present invention, the network virtualization edge is separated from a server at which the local management function is located, which reduces load of the server and improves performance of the data network center. |
