Abstract
A packet sending method, a network device, and a program product are disclosed, and pertain to the field of segment routing technologies. The method includes: A network device sends a packet which includes a segment routing header SRH and a payload, the SRH includes an encrypted field and an unencrypted field, the encrypted field includes at least an encrypted SID list, and the SID list indicates a transmission path of the packet. A SID list in an SRH of an SRv6 packet transmitted over a POP network is encrypted, thereby protecting SID information from being leaked. In addition, an intermediate node on a packet transmission path only needs to decrypt an encrypted field in the SRH to determine a next hop from the SID list, and does not need to decrypt the payload. This improves forwarding efficiency of the network device and protects secure transmission of the payload.
