Abstract:
1. A network communication method, comprising operating at layer 2 (L2) only, by performing: allocating an Ethernet (ETH) label through a layer 2 label allocation protocol on a L2 control plane; and performing data communication to another network node according to the allocated ETH label under control of the L2 control plane; wherein the allocating the ETH label through the layer 2 label allocation protocol on the L2 control plane, comprises: wherein the layer 2 label allocation protocol comprises an Ethernet header, a Label Management Type field, an Ingress MAC Address field, a Data Path ID field, an Egress MAC Address field, a Label Type field and a Label field, the Ethernet header comprises a destination address, a source address and a Ethernet Type, the Label Management Type field is used to indicate that the message is used in label allocation, the Ingress MAC Address field carries a layer 2 address of a source node device, the Egress MAC Address field carries a layer 2 address of the terminal node device, the Label Type field is used to indicate a type of the Data Path ID field and a type of the Label field, the type of the Data Path ID field is Ethernet Virtual Path or Ethernet Switched Path, the Label field forms the ETH label, or the Label field and the layer 2 address of the terminal node device form the ETH label, or the Label field, the layer 2 address of the source node device and the layer 2 address of the terminal node device form the ETH label.
