Abstract
Systems and methods are provided for congestion notification in mixed-fabric InfiniBand networks. In one aspect, a system and apparatus is provided wherein a receiving endpoint receives, from a sending endpoint, InfiniBand messages over a mixed-fabric network. The mixed-fabric network may include an InfiniBand transport layer and a non-InfiniBand messaging fabric. The non-InfiniBand massaging fabric may be any type of non-InfiniBand data-link-layer and network-layer network (e.g. Ethernet, IP). For example, the receiving endpoint may receive a non-InfiniBand protocol data unit (PDU) that contains at least a part of a first InfiniBand PDU as payload. The receiving endpoint may extract signaling from the received non-InfiniBand PDU that indicates whether congestion has been detected in the non-InfiniBand layers of the mixed-fabric network. The receiving endpoint may include the same or similar signaling in the header portion of a second InfiniBand PDU, and transmit the second InfiniBand PDU to the sending endpoint.
