Abstract: A system for facilitating sender-side granular congestion control is provided. During operation, the first and second processes of an application can run on sender and receiver nodes, respectively. A first buffer on the sender node can be allocated to the first process. For the first process, the system can then identify a second buffer at a last-hop switch of the receiver node. The system can determine, based on in-flight packets, the utilization of the second buffer. The system can also determine a fraction of available space in the second buffer for packets from the first buffer based on the utilization. Subsequently, the system can determine whether the fraction of the available space can accommodate the next packet from the first buffer. If the fraction of the available space can accommodate the next packet, the system can allow the first process to send the next packet to the second process.

Abstract: A credit-based flow control system can utilize speculative credit. If an agent has not received a credit return from a downstream agent for a given period of time, the agent can return speculative credit to an upstream agent. This way, even if the agent is not currently capable of performing operations represented by the speculative credit, the upstream agent can be enabled to proceed with operations.

Abstract: Techniques for embedding fabric addressing information within Ethernet media access control (MAC) addresses is disclosed herein and allows a multi-node fabric having potentially millions of nodes to feature Ethernet encapsulation without the necessity of a lookup or map to translate MAC addresses to fabric-routable local identifiers (LIDs). In particular, a locally-administered MAC address may be encoded with fabric addressing information including a LID. Thus a node may exchange Ethernet packets using a multi-node fabric by encapsulating each Ethernet packet with a destination MAC address corresponding to an intended destination. As the destination MAC address may implicitly map to a LID of the multi-node fabric, the node may use an extracted LID value therefrom to address a fabric-routable packet. To this end, a node may introduce a fabric-routable packet encapsulating an Ethernet packet onto a multi-node fabric without necessarily performing a lookup to map a MAC address to a corresponding LID.
