Claim of US Patent No. 10,798,760

1. A method for controlling a network slice by a system that comprises a control device and at least one forwarding device, the method comprising:receiving, by a first forwarding device, a first control packet sent by the control device, wherein the first control packet carries N pieces of control information and N network slice identifiers, the N pieces of control information are in a one-to-one correspondence with the N network slice identifiers, and a network slice identifier i corresponding to control information i is an identifier of a network slice controlled by using the control information i, wherein i?[1, N], and N?1;
determining, by the first forwarding device, M pieces of first control information from the N pieces of control information based on the N network slice identifiers, wherein the M pieces of first control information are in a one-to-one correspondence with M first network slices, and the M first network slices are borne on the first forwarding device, wherein M?1; and
controlling, by the first forwarding device, a first network slice j from the M first network slices based on first control information j from the M pieces of first control information, wherein j?[1, M].
