Abstract: A method includes, in a computing system that includes multiple compute nodes that run workloads and are connected by a network, establishing a dedicated Transport Control Protocol (TCP) connection over the network between a first compute node and a second compute node. Packets, which originate from one or more source workloads on the first compute node and are destined to one or more destination workloads on the second compute node, are identified and queued in the first compute node. The queued packets are aggregated in the first compute node into one or more TCP segments, and the TCP segments are sent over the dedicated TCP connection to the second compute node. In the second compute node, the TCP segments are received over the dedicated TCP connection, the packets are extracted from the received TCP segments, and the extracted packets are forwarded to the destination workloads.

Abstract: A method includes, in a source server, generating data that is to be sent over a Transmission Control Protocol (TCP) connection to a destination server. The data is transferred from the source server to an offload server using Remote Direct Memory Access (RDMA), while bypassing a local TCP stack of the source server. The data is assembled in the offload server in accordance with the TCP, and the assembled data is forwarded over the TCP connection to the destination server.
