Title:
METHOD AND HOST FOR IMPLEMENTING DATA PACKET SECURITY TRANSMISSION IN MULTI-HOMING AND MULTI-ADDRESS SPACE NETWORK
Document Type and Number:
WIPO Patent Application WO/2011/120454
Kind Code:
A3
Abstract:
A method for implementing data packet security transmission in a multi-homing and multi-address space network is disclosed by the embodiments of the present invention. The method includes: when a location domain identifier and local location information of a source host carried in a first data packet which is transmitted from the source host and received by a destination host are different from the location domain identifier and the local location information of the source host stored in previous communication, the destination host actively transmits location reset confirmation request information; after receiving the information from the source host that the location domain identifier and the local location information of the source host have been reset, the destination host transmits the data packets to the source host according to the reset location domain identifier and local location information of the source host. A corresponding source host and destination host are also provided by the embodiments of the present invention. As a data packet security transmission mechanism is established between the destination host and the source host, with the technical solutions of the present invention, the Distributed Denial Of Service (DDOS) attacks on other hosts in the network can be avoided, wherein the attacks are caused by modification of the location domain identifier and the local location information carried in the data packets by the hackers.
