Title:
PACKET PROCESSING METHOD, APPARATUS AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/252569
Kind Code:
A1
Abstract:
The present application provides a packet processing method, apparatus and system. In the present application, when an SFF receives a packet in an SR encapsulation format, the SFF modifies the encapsulation format of the packet, encapsulates an IP header in the packet on an outer layer of an SR header, and sends the modified packet to an SF. In the process of forwarding the packet from the SFF to the SF, the packet still carries the SR header. Therefore, when the packet is subsequently returned from the SF to the SFF, the SFF can restore the original SR encapsulation format by using the SR header carried in the packet. so as to get rid of the limitation that the buffer space for storing the SRH is necessarily generated and maintained to recover the SR encapsulation format, thereby avoiding the huge resource overhead caused by the generation and maintenance of the buffer space used for saving an SRH, and saving the resource overhead.
