Abstract: Systems, methods, and computer-readable media for reducing distributed storage operation latency using segment routing. In some examples, a method can involve receiving, from a client, a message identifying an intent to store or retrieve data on a distributed storage environment, and sending to the client a segment routing (SR) list identifying storage node candidates for storing or retrieving the data. The method can involve steering a data request from the client through a path defined by the SR list based on a segment routing header (SRH) associated with the request, the SRH being configured to steer the request through the path until a storage node from the storage node candidates accepts the request. The method can further involve sending, to the client device, a response indicating that the storage node has accepted the request and storing or retrieving the data at the storage node that accepted the request.

Abstract: A method is provided in one example embodiment and includes, for each of a plurality of individual storage units collectively comprising a virtual storage unit, mapping an internal address of the storage unit to a unique IP address, wherein each of the storage units comprises a block of storage on one of a plurality of physical storage devices and wherein the IP address includes a virtual storage unit number identifying the virtual storage unit; receiving from a client a request to perform an operation on at least one of the data storage units, wherein the request identifies the internal address of the at least one of the data storage units; translating the internal address of the at least one of the data storage unit to the unique IP address of the at least one of the data storage units; and performing the requested operation on the at least one of the data storage units.

Abstract: A method is provided that is performed by a smart network interface card (SmartNIC) that is in communication with a host device that serves as a forwarder in an Hybrid Information-Centric Network (hICN). The method includes storing in a memory of the SmartNIC, mapping information that maps a subset of names of content contained in a content store that is stored in a memory of the host device to corresponding addresses of the content. The method further includes receiving at the SmartNIC, from a requester, an interest that includes a name, and determining whether the name of the interest is included in the mapping information stored in the SmartNIC. The method includes processing the interest based on whether the name of the interest is contained in the mapping information stored in the memory of the SmartNIC.

Abstract: Establishing an expected transmit time at which a network interface controller (NIC) is expected to transmit a next packet. Enqueuing, with the NIC and before the expected transmit time, a packet P1 to be transmitted at the expected transmit time. Upon enqueuing P1, incrementing the expected transmit time by an expected transmit duration of P1. Transmitting at the NIC's line rate and timestamping enqueued P1 with its actual transmit time. Adjusting the expected transmit time by a difference between P1's actual transmit and P1's expected transmit time. Requesting, before completion of transmitting P1, to transmit a P2 at time t(P2). Enqueuing, in sequence, zero or more P0, such that the current expected transmit time plus the duration of the transmission of the P0s at the line rate equals t(P2). Transmitting at the line rate each enqueued P0. Upon enqueuing each P0, incrementing, for each P0, the expected transmit time by the expected transmit duration of the P0. Enqueuing P2 for transmission directly following enqueuing the final P0. Transmitting, by the NIC, enqueued P2 at t(P2).
