Title: METHOD AND DEVICE FOR FORWARDING DATA PACKET
Abstract:
The embodiments of the present application relate to the technical field of communications, especially to a method and device for forwarding a data packet, for reducing entries in a forwarding table on an SFF, thereby improving the forwarding efficiency of the SFF. In the embodiments of the present application, a first SPI, an SI and a second SPI are encapsulated in an NSH of a data packet, wherein the first SPI indicates a first service link path currently forwarding the data packet, the second SPI indicates a second service link path specified by a service link controller for a service link where the data packet is located, and the first service path is partially overlapped with the second service path. In the embodiments of the present invention, by means of indicating an overlapped part of a first service link path and a second service link path with a first SPI, path information in a forwarding table can be multiplexed, thus reducing the number of entries in a forwarding table, and thereby reducing the amount of memory occupied by the forwarding table.
