Abstract

A network interface of a network user having at least one physical interface for connecting the network interface to a network interface of a different network user, at least one data selector, which is connected to the physical interface and which is suitable for receiving data from the physical interface and sending data to the physical interface, and at least one data switch, which is connected to the data selector and which is suitable for receiving data from the data selector and sending data to the data selector.

First claim

1 . A network interface of a network user comprising:
at least one physical interface for connecting the network interface to a network interface of a second network user; at least one data selector connected to the at least one physical interface via at least one first data connection line, the at least one data selector comprising a data receiver configured for providing a data receiving connection to the at least one physical interface, and a data transmitter configured for providing a data transmitting connection to the at least one physical interface; and at least one data switch connected to the at least one data selector via at least one second data connection line and configured for receiving incoming data from the at least one data selector or transmitting outgoing data to the at least one data selector, wherein the at least one data selector is configured for forwarding data received from the at least one physical interface to the second network user and to the at least one data switch, and wherein the at least one data selector is further adapted to duplicate the data received from the at least one physical interface in a downlink and to forward the received data to a different network user and to the at least one data switch, without an intermediate storage.

2 . The network interface according to claim 1 , wherein the network interface of the network user has a first one of the at least one physical interface for the downlink and a second one of the at least one physical interface for an uplink.

3 . The network interface according to claim 1 , wherein the network interface of the network user is part of a client network user or part of a server network user.

4 . The network interface according to claim 1 , wherein the at least one data selector is adapted to carry out a timing recovery for incoming data from a physical interface.

5 . The network interface according to claim 1 , wherein the at least one data selector is connected to the at least one physical interface and to the at least one data switch for transmitting data between the at least one physical interface and the at least one data switch of the network interface, and
wherein a control device of the network interface of the network user is connected at least to the at least one data selector, the at least one physical interface and the at least one data switch in such a manner that control signals are transmittable between the control device and the at least one data selector, the at least one physical interface and the at least one data switch.

6 . The network interface according to claim 5 , wherein the control device is connected to the network user via a status line, to receive status information of the network user.

7 . The network interface according to claim 1 , wherein a network interface of a server network user is configured to send and to receive data in the downlink and an uplink via the at least one data switch in each case.

8 . The network interface according to claim 1 , wherein a network interface of a server network user is configured for comparing data received from a last client network user in the downlink with data that were sent by the server network user to a first client network user.
