20 Claims

1. A method for network performance calculation implemented by a second network node, wherein the method comprises:

receiving, from a first network node, a packet comprising a segment list, wherein a destination address of the packet matches a first segment identifier of the second network node, wherein the first segment identifier comprises a locator, a flag, and a function, and wherein the flag indicates a network performance parameter type;

replacing a value of the destination address with a second segment identifier that is of a third network node and that is in the segment list;

obtaining, according to the network performance parameter type, a network performance parameter;

adding the network performance parameter into the second segment identifier to create a modified packet; and

sending, to the third network node, the modified packet.
