Abstract: Systems and methods are directed toward proactive and/or reactive notification and connection parameter adjustments responsive to live migration events. When an application or program is migrated to new underlying hardware, messages may be provided to associated senders to dynamically and/or temporarily adjust different connection parameters to reduce a likelihood of determining the connection is inactive. A proactive notification may broadcast status information during the live migration to each node in a network and/or to particular nodes associated with the migrating receiver. A reactive notification may provide a message regarding receiver status responsive to receiving incoming traffic.

Abstract: In one embodiment, a system includes a digitally controlled oscillator (DCO) to generate a local clock having a local clock frequency, and clock synchronization circuitry to receive from a device a signal indicative of a remote clock frequency, compare measures of the remote clock frequency and the local clock frequency; generate a digital control command based on the comparison; and provide the digital control command to the DCO, wherein the DCO is to adjust the local clock frequency responsively to the digital control command.

Abstract: In one embodiment, a processing system includes an interface controller to receive a data signal from a remote link partner over a link, and recover a clock signal from the received data signal, frequency generation circuitry to receive the recovered clock signal, and output a local clock signal responsively to the received recovered clock signal, wherein the interface controller is configured to drive a transmit symbol rate responsively to the local clock signal, and a digital control loop including the interface controller and the frequency generation circuitry, wherein the interface controller is configured to identify a clock drift, generate a digital control signal responsively to the clock drift, and send the digital control signal to the frequency generation circuitry, which is configured to adjust a frequency of the local clock signal responsively to the digital control signal in order to reduce the clock drift.

Abstract: In one embodiment, a monitoring device includes an interface to receive symbols from at least one monitored device over at least one communication link, at least one counter to track a number of the symbols received from the at least one monitored device over the at least one communication link, and processing circuitry to monitor synchronization of at least one clock of the at least one monitored device based on at least one value of the at least one counter.
