Abstract
An anti-replay processing method. The method is utilized in a service function path (SFP) to monitor packet count in the SFP to identify replay attack event, and recognizes a segment of the SFP where the replay attack event occurs as an insecure path. The method further initiates a secure path bypassing the insecure path, labels normal SFC packets with an asserted secure flag, and blocks replayed packets without the asserted secure flag at the exit stage of the secure path.
