It is described a network attack detection method. A topology analysis on network is conducted to obtain a probing path set containing at least one probing path. A first probing path contained in the probing path set is probed by using a probing pattern to obtain a performance metric of the first probing path. It is determined whether the first probing path is subjected to network attack according to the performance metric and a control performance metric.

Network attack detection method

It is described an information processing method and device. It is received a request for service data from a client device. In response to the request for service data, it is sent at least two probing packets which contain the service data to the client device on a forward path which is from a server to the client device. It is obtained timing information, which includes: a time stamp corresponding to the service data, a time stamp corresponding to the request for the service data, and time stamps corresponding to at least two backward-path packets sent by the client device on a backward path, the backward path being from the client device to the server. It is determined according to the timing information a one-way path metric.
