Abstract
A method for forwarding data content from a second data connection and a third data connection of a node of a data network to a first data connection of the node, wherein data content received at the second data connection has priority over data content received at the third data connection, includes interrupting forwarding of data content received via the third data connection as soon as reception of data content at the second data connection is detected. The data content received at the second data connection is fed into an intermediate buffer (memory) and the output of the data content received via the second data connection, via the first data connection, is delayed for a definable time period.
Claims13
A method for forwarding data content from a second data connection and a third data connection of a node of a data network of an elevator system to a first data connection of the node, wherein the node operates to output a first data telegram that forms first data content via the first data connection according to a selected Ethernet protocol, receive a second data telegram that forms second data content via the second data connection according to the Ethernet protocol, receive a third data telegram that forms third data content via the third data connection according to the Ethernet protocol, derive the first data telegram either from the second data telegram or the third data telegram, and receive seventh data content via a fourth data connection of the node, the method comprising the steps of:
- interrupting forwarding of the third data content received via the third data connection when reception of the second data telegram via the second data connection is detected;
- conducting the received second data telegram into an intermediate buffer;
- delaying output from the intermediate buffer of the second data content received via the second data connection, via the first data connection, for a definable time period;
- and
- delay-free integration of the seventh data content received when forwarding the second data content, received via the second data connection, to the first data connection in the first data telegram output via the first data connection.
A node of a data network, the node comprising:
- a first data connection, a second data connection, a third data connection, a fourth data connection and an intermediate buffer;
- and
- wherein the node is adapted to
- output a first data telegram, forming first data content, via the first data connection according to a selected Ethernet protocol,
- receive a second data telegram, forming second data content, via the second data connection according to the selected Ethernet protocol,
- receive a third data telegram, forming third data content, via the third data connection according to the selected Ethernet protocol,
- receive seventh data content via the fourth data connection,
- derive the first data telegram either from the second data telegram or from the third data telegram,
- interrupt forwarding of the third data content received via the third data connection upon detecting reception of the second data telegram via the second data connection,
- route the received second data telegram into the intermediate buffer,
- delay the outputting of the second data content, received via the second data connection, from the intermediate buffer via the first data connection for a definable time period, and
- integrate the received seventh data content, when forwarding the second data content to the first data connection, delay-free into the first data telegram output via the first data connection.
