Methods and systems for network congestion management

A method comprising:

• receiving, at a first component, a first packet complying with an InfiniBand protocol, wherein the first packet comprises a first set of data associated with an Ethernet protocol or an Internet protocol;
• and
• outputting, at the first component, a second packet complying with the InfiniBand protocol, wherein the second packet comprises an explicit congestion notification (ECN) or a quantized congestion notification (QCN) that is associated with the Ethernet protocol or the Internet protocol, the ECN or QCN is representative of a presence of network congestion associated with the first component.

A method comprising:

• receiving, at a network gateway, an InfiniBand packet complying with an InfiniBand protocol, the InfiniBand packet comprising a backward explicit congestion notification (BECN) representative of a presence or absence of network congestion associated with a second component;
• and
• outputting, at the network gateway, an Ethernet packet complying with an Ethernet protocol or an Internet Protocol (IP) packet complying with an Internet protocol, the Ethernet packet or the IP packet comprising an explicit congestion notification (ECN) representative of the presence or absence of network congestion associated with the second component based, at least in part, on the BECN.

A system comprising:

• a receiver configured to receive a first packet complying with an InfiniBand protocol, wherein the first packet comprises a first set of data associated with an Ethernet protocol or an Internet protocol;
• and
• a transmitter configured to output a second packet complying with the InfiniBand protocol, wherein the second packet comprises an explicit congestion notification (ECN) or a quantized congestion notification (QCN) that is associated with the Ethernet protocol or the Internet protocol, the ECN or QCN is representative of a presence of network congestion.

A network gateway comprising:

• a receiver for receiving an InfiniBand packet complying with an InfiniBand protocol, the InfiniBand packet comprising a backward explicit congestion notification (BECN) representative of a presence or absence of network congestion associated with a second component;
• and
• a transmitter for outputting an Ethernet packet complying with an Ethernet protocol or an Internet Protocol (IP) packet complying with an Internet protocol, the Ethernet packet or the IP packet comprising an explicit congestion notification (ECN) representative of the presence or absence of network congestion based, at least in part, on the BECN.
