Abstract
An Ethernet switch has a header device with a crossbar device and a number of downstream interface modules with a first number of a series of ports and a second number of a series of ports, respectively, such that in each case the same one in the series of the first number of ports is connected to a switching control unit coupled to an interface device, and the further ports in the series of the first number of ports are connected to a port in the second number of the series of ports via respective data lines routed in cascade form.

An interface module (2a, 2b, 2c, 2d) comprising:
- a first number of a series (5a, 5b, 5c, 5d) of ports (51a, 52a, 53a, 54a, 51b, 51c, 51d) and
- a second number of a series (6a, 6b, 6c, 6d) of ports (61a, 62a, 63a, 64a), where a first port (51a, 51b, 51c, 51d) in the first number oaf series of ports (51a, 52a, 53a, 54a, 51b, 51c, 51d) is connected by means of at least one data line not to any port (61a, 62a, 63a, 64a) in the series of the second number (6a, 6b, 6c, 6d) of ports but to a switching control unit (3a, 3b, 3c, 3d) connected to an interface device (4a, 4b, 4c, 4d), and where the subsequent input ports (52a, 53a, 54a) in the first number of a series (5a, 5b, 5c, 5d) of ports are connected in order by means of at least one respective data line to the ports (61a, 62a, 63a, 64a) in the series of the second number of a series (6a, 6b, 6c, 6d) of ports, starting with a first (61a) in the series of the second number of ports such that the second port (52a) in the series (5a, 5b, 5c, 5d) of the first number of ports is connected only to the first port (61a) in the series of the second number (6a, 6b, 6c, 6d) of ports, the third port (53a) in the series (5a, 5b, 5c, 5d) of the first number of ports is connected only to the second port (62a) in the series of the second number (6a, 6b, 6c, 6d) of ports, and so on.
A method, including an interface module (2a, 2b, 2c, 2d) comprising:
- a first series (5a, 5b, 5c, 5d) of ports 51a, 52a, 53a, 54a, 51b, 51c, 51d) and
- a second number of a series (6a, 6b6c, 6d) of ports (61a, 62a, 63a, 64a), where a first port (51a, 51b, 51c, 51d) in the first number of a series of ports (51a, 52a, 53a, 54a, 51b, 51c, 51d) is connected by means of at least one data line not to any port (61a, 62a, 63a, 64a) in the series of the second number (6a, 6b, 6c, 6d) of ports but to a switching control unit (3a, 3b, 3c, 3d) connected to an interface device (4a, 4b, 4c, 4d), and where
- the subsequent input ports (52a, 53a, 54a) in the first number of a series (5a, 5b, 5c, 5d) of ports are connected in order by means of at least one respective data line to the ports (61a, 62a, 63a, 64a) in the series of the second number of a series (6a, 6b, 6c, 6d) of ports, starting with a first (61a) in the series of the second number of ports such that the second port (52a) in the series (5a, 5b, 5c, 5d) of the first number of ports is connected only to the first port (61a) in the series of the second number (6a, 6b, 6c, 6d) of ports, the third port (53a) in the series (5a, 5b, 5c, 5d) of the first number of ports is connected only to the second port (62a) in the series of the second number (6a, 6b, 6c, 6d) of ports, and so on,
- in which each switching control unit (3a, 3b, 3c, 3d) is produced as part of an interface module (2a, 2b, 2c, 2d) such that information to be transmitted to a downstream interface module (2b, 2c, 2d) from the crossbar device (7) is routed through the respective upstream interface module (2a, 2b, 2c) in cascade form.
