Abstract: A high performance mechanism for exporting peripheral services and offloads using Direct Memory Access (DMA) engine is presented. The DMA engine comprises a ring buffer, a DMA memory, and a DMA engine interface operatively coupled to the ring buffer and the DMA memory. The DMA engine interface is configured to retrieve, from the ring buffer, a first DMA request; extract first transfer instructions from the first DMA request; retrieve a first data corresponding to the first DMA request from the DMA memory; and execute the first DMA request using the first data based on at least the first transfer instructions.

Abstract: A transceiver module for providing operational resilience is presented. The transceiver module is configured to receive first data via a first optical module in a first configuration of operation and detect, using an adapter that is operationally connected to the first optical module, an operational failure of the first optical module. In response to detecting the operational failure, the transceiver module is configured to switch, via the adapter, from the first configuration of operation to a second configuration of operation by: automatically engaging a second optical module; triggering the first data that was initially directed into a first input port of the first optical module to be directed into a second input port of the second optical module; and receiving the first data from a second output port of the second optical module.

Abstract: Systems, computer program products, and methods are described herein for dynamic reconfiguration of network communications. An example system includes a first network pod including a first set of network ports, a second network pod including a second set of network ports, a set of network cores, and a first intermediate network switch. The first intermediate switch operatively couples the first network pod, the second network pod, and the set of network cores. The first intermediate network switch is configured to selectively establish full bisectional bandwidth data communication between a subset of the set of network cores, a subset of the first set of network ports, and a subset of the second set of network ports.

Abstract: Systems, computer program products, and methods are described herein for machine learning (ML) based network resilience and steering. An example system monitors data traffic across one or more network ports and determines a first data traffic pattern from the data traffic. The system further determines, via a ML subsystem, that the first data traffic pattern is indicative of a security threat to a first network port. In response to determining that the first data traffic pattern is indicative of the security threat to the first network port, the system further isolates the first network port from the one or more network ports.

Abstract: A datacenter environment having a plurality of servers, leaf switches, and spine switches is presented. A transceiver module facilitates reliable data transmission across network layers. The transceiver module includes a first optical module to facilitate data transmission between a server and a leaf switch, and a second optical module to facilitate data transmission between the leaf switch and a spine switch. An adapter operatively coupled to both optical modules manages data flow under different configurations. In a first configuration, the adapter receives first data from the server via the first optical module and second data from the leaf switch via the second optical module. Upon detecting an operational failure in the first optical module, the adapter terminates reception of second data from the leaf switch and switches to a second configuration, in which it redirects the first data from the server through the second optical module.

Abstract: Network devices and associated methods are provided for synchronization in an optically switched network. The network device includes one or more ports in communication with a plurality of devices via an optical switch. The one or more ports receive a master clock signal having a first frequency from a first device of the plurality of devices. The network device includes a local clock in communication with the one or more ports and operating at a second frequency. The network device includes a synchronization manager in communication with the one or more ports and the local clock and configured to be enabled and disabled. When the synchronization manager is enabled, it receives the master clock signal via the one or more ports and transmits an instruction to the local clock to operate at the first frequency.

Abstract: Systems, computer program products, and methods are described herein for machine learning (ML) based system for network resilience and steering. An example system monitors data movement across one or more network ports; extracts network performance indicators associated with the data movement; determines, via a machine learning (ML) subsystem, that a status of a first network port is indicative of operational failure based on at least the network performance indicators; determines a redundant network port and an intermediate network switch in the same network port cluster as that of the first network port; and triggers the intermediate network switch to reroute a portion of network traffic from the first network port to the redundant network port in response to the status of the first network port by terminating a communication link to the first network port until the operational failure of the first network port is resolved.
