Claim 25:
26. The network device according to claim 21, wherein the packet comprises a first flag, the first flag is used to indicate that the length of the compressed segment identifier is X bytes, X is a positive integer, the packet comprises a second flag, and the second flag is used to indicate that the compressed segment list comprises the compressed segment identifier, and wherein the at least one processor is further configured to execute the programming instructions to cause the network device to:
receive a fourth control packet from a controller in a network, wherein the fourth control packet comprises a fourth flag, a value of the fourth flag is N, and N is a positive integer;
read the compressed segment identifier from the compressed segment list based on an indication of the second flag, wherein the length of the compressed segment identifier is the X bytes; and
obtain the first part of the compressed segment identifier and the second part of the compressed segment identifier from the compressed segment identifier based on an indication of the fourth flag, wherein a length of the first part of the compressed segment identifier is X−M+N bytes, M is a positive integer greater than N, and a length of the first part of the original segment identifier is M bytes.
