Abstract: In an example, memory register interrupt based signaling and messaging may include receiving, at a control register of a receiver, a signal number from a sender, and copying, by a memory register interrupt management device of the receiver, the signal number to an associated status register of the receiver. Further, memory register interrupt based signaling and messaging may include generating, independently of the signal number from the status register, an interrupt to a central processing unit of the receiver, and triggering, based on the interrupt, an interrupt handler of the receiver to perform an action associated with the signal number.

Abstract: Example embodiments relate to providing efficient routing in software defined networks. In example embodiments, an indirect group table includes a first group entry that is associated with a first route tree in a software defined network. A failure is detected in the first route tree during a data transmission, and a notification of the failure is sent to a remote controller device, where the remote controller device identifies a second route tree that does not include the failure. After the remote controller device updates the first group entry to be associated with the second route tree, the data transmission is performed using the second route tree.

Abstract: A system maintains a queue for storing packets, which are enqueued at a tail of the queue and dequeued at a head of the queue. The system computes a queue utilization value, based on the packets stored in the queue. The system computes an excess amount value, based on the packets stored in the queue and previously tagged as excess packets. The system receives a first packet at the tail of the queue and determines whether a difference between the queue utilization value and the excess amount value exceeds a predetermined threshold. Responsive to determining that the difference exceeds the predetermined threshold, the system tags the first packet as an excess packet. Responsive to tagging the first packet as an excess packet, the system performs an operation associated with the first packet or a second packet at the head of the queue to reduce congestion.

Abstract: Determination of an inflection point in congestion in a network path can include determining packet congestion on a network path using an inflection point mechanism (IPDM), detecting a potential inflection point in response to a one-way delay (OWD) of a first packet being lesser than an OWD of a second packet by a quantity greater than a function of a difference of inter departure time (IDT) between the first packet and the second packet, and determining an inflection point in congestion of the network path based on the potential inflection point.

Abstract: Some examples described herein provide for a partially coherent memory transfer. An example method includes moving data directly from a coherence domain of an originating symmetric multiprocessor (SMP) node across a memory fabric to a target location for the data within a coherence domain of a receiving SMP node.

Abstract: Various aspects of the subject technology relate to methods, systems, and machine-readable media for multi-path transmission control protocol (MP-TCP) proxy tunneling. The method includes reading a first multi-path transmission control protocol (MP-TCP) information from at least one first MP-TCP header, the at least one first MP-TCP header included in a first MP-TCP subflow, the first MP-TCP subflow included in a first MP-TCP session. The method also includes encapsulating the first MP-TCP information in a second MP-TCP session, the second MP-TCP session different from the first MP-TCP session. The method also includes sending the first MP-TCP information through the second MP-TCP session.

Abstract: The disclosed systems and methods provide end-to-end multipath TCP (MPTCP) through a network gateway. The method includes detecting a MPTCP subflow having a first IP address as a source address and a second IP address as a destination address, wherein none of the gateways is the source or the destination of the MPTCP subflow; associating a third IP address with the MPTCP subflow; and advertising, to at least one endpoint of the MPTCP subflow, the third IP address.
