METHOD, DEVICE, AND MULTI-ADDRESS SPACE MOBILE NETWORK FOR SENDING DATA AND FORWARDING DATA

摘要

A method for forwarding data is provided. A first host belongs to a first locator domain (LD). The first LD belongs to a first Internet service provider (ISP) and a second ISP. A second host belongs to a second LD. The ISP to which each LD belongs allocates an LD identifier (LD ID) to the LD, respectively. The method includes: receiving a first data packet sent to the second host by the first host; selecting one LD ID of the first LD as a source LD ID according to a preset traffic engineering (TE) policy, so as to obtain a second data packet corresponding to the first data packet, and selecting an ISP network corresponding to the source LD ID to forward the second data packet.
