Abstract
A repeater for transferring same-destination frames that are addressed to a destination Electronic Control Unit (ECU) efficiently by receiving the frames from respectively different ports, includes: four ports; and a switcher, wherein the first and second ports respectively originating a communication path to an individual ECU, and the third and fourth ports respectively connected to an individual ECU that is different from the one connected the first and second ports, and when the same-destination frames are received by the third and fourth ports of the repeater at the same time, the switcher distributes the same-destination frames among the first and second ports to be transferred via two, i.e., different, communication paths toward one, i.e., same, destination ECU.
Claims12
A repeater, comprising:
- ports for receiving and transmitting frames, including
- a first species port, provided as at least two pieces of the first species port in one repeater respectively to connect with a first plurality of communication nodes;
- a second species port, provided as at least two pieces of the second species port in one repeater respectively to connect with at least two communication paths, the at least two communication paths respectively leading to a second plurality of communication nodes, the second plurality of communication nodes being different from the first plurality of communication nodes that are respectively connected with the first species port;
- and
- a distributive transferer transmitting frames having a same destination node that is reachable via either of the at least two communication paths, when the at least two pieces of the first species port simultaneously receive the frames having the same destination node.
A communication network system, comprising:
- a repeater, having ports for receiving and transmitting frames, the repeater including:
- a first species port, provided as at least two pieces of the first species port in one repeater respectively to connect with a first plurality of communication nodes;
- a second species port, provided as at least two pieces of the second species port in one repeater respectively to connect with at least two communication paths, the at least two communication paths respectively leading to a second plurality of communication nodes, the second plurality of communication nodes being different from the first plurality of communication nodes that are respectively connected with the first species port;
- and
- a distributive transferer transmitting frames having a same destination node that is reachable via either of the at least two communication paths, when the at least two pieces of the first species port simultaneously receive the frames having the same destination node.
