A non-volatile memory express over fabrics (NVMe-oF) target accelerating apparatus according to an embodiment of the present disclosure includes: a first offload engine configured to offload a network stack to compute a first network packet and output a first packet payload; and a second offload engine configured to offload an NVMe-oF stack to compute the first packet payload and output data having a first buffer address when the first packet payload is of a first type.

A method and system for exchanging network packets in a memory system is provided. A size of each network packet to be transmitted is determined. Each network packets is segregated into one of plural queues based on the size of the network packet. Each network packet is transmitted over a shared memory, according to the queue in which the network packet is segregated.

Systems and methods are provided for performing routing in a switch network or fabric. Switches can be configured in a hierarchical topology having a plurality of groups, where switches in a group are connected to one another, and groups are connected to other groups. Routing can be performed by maintaining per-group group load information. A packet can be routed between at least two groups using the per-group group load information to effect a set of routing decisions. The set of routing decisions can be biased towards or away one or more paths.

Systems and methods are provided for on the fly routing of data transmissions in the presence of errors. Switches can establish flow channels corresponding to flows in the network. In response to encountering a critical error on a network link along a transmission path, a switch can generate an error acknowledgement. The switch can transmit the error acknowledgements to ingress ports upstream from the network link via the plurality of flow channels. By transmitting the error acknowledgement, it indicates that the network link where the critical error was encountered is a failed link to ingress ports upstream from the failed link. Subsequently, each ingress port upstream from the failed link can dynamically update the path of the plurality of flows that are upstream from the failed link such that the plurality of flows that are upstream from the failed link are routed in a manner that avoids the failed link.
