Abstract
An apparatus includes a first node configured to receive the data packets from a plurality of source nodes of the data network and to selectively route some of the received data packets to a link via a port of the first node. The apparatus also includes a link-input buffer that is located in the first node and is configured to store the some of the received data packets for transmission to the link via the port. The first node is configured to power off hardware for transmitting received data packets to the link in response to a fill level of the link-input buffer being below a threshold.
Claims12
An apparatus comprising:
- a first node configured to receive a plurality of data packets from a plurality of source nodes of a data network and to selectively route a first portion of the received data packets to a link via a port of the first node;
- and
- a link-input buffer being located in the first node and being configured to store the first portion of the received data packets for transmission to the link via the port;
- and
- wherein the first node is configured to power off hardware for transmitting received data packets to the link in response to a fill level of the link-input buffer being below a threshold;
- wherein the first node is configured to selectively transmit a second portion of the data packets received therein to a second link connected to another port of the first node;
- wherein a second link-input buffer is located in the first node and being configured to store the second portion of the data packets received by the first node for transmission to the second link;
- and
- wherein the first node is configured to power off hardware for transmitting data packets to the second link in response to a fill level of the second link-input buffer being below a third threshold.
A method, comprising:
- receiving a plurality of data packets, by a first node, from a plurality of source nodes of a data network;
- selectively routing a first portion of the received data packets to a link via a port of the first node;
- storing the first portion of the received data packets in a link-input buffer being located in the first node;
- powering off hardware for transmitting received data packets to the link in response to a fill level of the link-input buffer being below a threshold;
- selectively transmitting a second portion of the data packets received to a second link connected to another port of the first node;
- storing the second portion of the received data packets in a second link-input buffer being located in the first node;
- and
- powering off second hardware for transmitting received data packets to the second link in response to a fill level of the second link-input buffer being below a threshold.
