Abstract
A method for protecting a stream of packets in a network composed of packet router nodes and stream transmitter and receiver nodes. The receiver node is connected to a router node handling routing of a packet to the receiver node according to an expected value of a protection parameter included in at least one field of a packet of the stream. The method is implemented by a device associated with the receiver node and includes: transmitting to the router node connected to the receiver node a message containing the expected value of the protection parameter. A method is also provided for filtering a stream of packets, which is implemented by the router node connected to the receiver node and includes: receiving from a device associated with the receiver node a message containing the expected value of the protection parameter, and filtering packets not containing the expected value of the parameter.
