Abstract:
The invention provides methods and devices for reporting and parsing the errors of a packet based on IPSec protocol family in a communication network. Concretely, the reserved field in ICMP security failure message is used to denote the error type at the second level of the error in the packet. With the aid of the solution provided by the invention, it is possible to report the error types for a tunnel packet which has an error in detail. And the source termination device can ascertain the error types of a tunnel packet, so as to eliminate the error.
