A method for restoring a service reservation booking system in a network after a failure, that comprises a first step of invalidating at least a portion of the bookings which cannot be seen anymore by the service booking system due to the failure, a second step of recalculating the bookings which cannot be seen anymore by the service booking system by validating the bookings which are valid in the network topology after the failure and by cancelling the bookings which are invalid in the network topology after the failure. Advantageously, the method of the present invention further includes a third step during which the nodes of the network disappear from the service booking system. The present invention also includes to a service booking system in a network.

The invention concerns a device for transmitting packets in a packet communication network comprising at least two stations, characterized in that it includes means for: The invention also concerns a device for receiving packets in a packet communication network comprising at least two stations.

Transmitting a synchronizing signal in a packet network

A synchronization aid device is part of receiving communication equipment of an IP network, having a primary clock signal consisting of primary clock pulses spaced apart by a first period. This device comprises i) a required to increment its value by one unit on each primary clock pulse and reset its value to zero each time it reaches a value M, ii) detection means required to generate a secondary clock pulse each time the value of the counter is zero, the secondary clock pulses forming a secondary clock signal having a second period equal to M times the first period, and iii) control means required, each time the receiving equipment receives a packet containing at least one first bit having a first value, to initialize the counter with a chosen value.
