A network switch includes one or more queues to hold packets received from a first input flow and a second input flow. The network switch also includes a packet communication switch configured to access a first header of a first packet in the one or more queues and a second header of a second packet in the one or more queues. The first header includes first machine learning (ML) information that represents a first set of state transition probabilities under a set of actions performed at the network switch. The second header includes second ML information that represents a second set of state transition probabilities under the set of actions performed at the network switch. The packet communication switch is configured to selectively modify the first header or the second header based on a comparison of the first ML information and the second ML information.

A server includes a field programmable gate array (FPGA) partitioned into a set of partial reconfiguration (PR) slots and a memory that supports a set of logical buffers. A deterministic application request module (DARM) receives application requests to allocate the set of reconfiguration slots to one or more tenants and the one or more tenants configure the allocated reconfiguration slot to perform tasks. The DARM stores data associated with the application request in a first logical buffer from the set of logical buffers. A reconfiguration slot scheduling (RSS) module identifies a first reconfiguration slot from the set of reconfiguration slots and associates the first reconfiguration slot with the first logical buffer. A reconfiguration slot initialization (RSI) module reconfigures the first reconfiguration slot to perform the tasks based on the data stored in the first logical buffer.

A processor instantiates a virtual network function (VNF) and a probe to monitor at least one metric associated with the VNF. The processor also allocates a pool of ports to the probe. A transceiver establishes one or more first interfaces between the probe and one or more applications using one or more first ports from the pool of ports. Information such as metrics generated by the ports is concurrently exchange between the probe and the applications using the first interfaces. In some cases, a second interface is established between the probe and a monitoring server. The probe reports mission critical events to the applications via the first interfaces and non-mission critical events to the monitoring server via the second interface concurrently with reporting the mission critical events.

A node in a mesh network includes insertion circuitry to selectively delay first packets prior to insertion in a mesh network by a first time interval corresponding to a maximum failure detection time interval for the mesh network based on whether a failure has been detected in the mesh network. The node includes reception circuitry configured to selectively delay second packets received from the mesh network by a second time interval depending on whether the failure has been detected. The second time interval equals a maximum latency for the mesh network minus a sum of the maximum failure detection time interval and a propagation time along a working path. If a failure is detected, the second packets are delayed by a third time interval determined based on the maximum latency, the maximum failure detection time interval, and a propagation time along a backup path for the working path.

The optical packet is not processed by the digital processing circuit or results of processing are not used to configure the analog switch during a second time interval. The analog switch routes the optical packet between the input and output ports based on second configuration information during the second time interval.
