The present invention relates to a communications network end station (1) which uses the Resource Reservation Protocol (RSVP) to reserve a quality of service, for communication with a second end station (3), over a communications network. The end station includes an interface (5) which connects a host processor (4) to the communication network and an RSVP signalling module (7) which is coupled to the host processor and which produces and processes resource reservation messages for reserving a quality of service determined by one of the end stations. Once generated, the resource reservation messages are transferred to the network via the host processor (4). A controller (9) is used to control the transfer of the data from the host processor (4) to the interface (5) so as to achieve the determined quality of service. The controller also transfers resource reservation messages between the interface and processor. An RSVP detector (10) is coupled to the controller (9) to detect resource reservation messages and determine from these messages the required quality of service. The detector then instructs the controller (9) to control the transfer of the data accordingly.
