Abstract: Establishing an expected transmit time at which a network interface controller (NIC) is expected to transmit a next packet. Enqueuing, with the NIC and before the expected transmit time, a packet P1 to be transmitted at the expected transmit time. Upon enqueuing P1, incrementing the expected transmit time by an expected transmit duration of P1. Transmitting at the NIC's line rate and timestamping enqueued P1 with its actual transmit time. Adjusting the expected transmit time by a difference between P1's actual transmit and P1's expected transmit time. Requesting, before completion of transmitting P1, to transmit a P2 at time t(P2). Enqueuing, in sequence, zero or more P0, such that the current expected transmit time plus the duration of the transmission of the P0s at the line rate equals t(P2). Transmitting at the line rate each enqueued P0. Upon enqueuing each P0, incrementing, for each P0, the expected transmit time by the expected transmit duration of the P0. Enqueuing P2 for transmission directly following enqueuing the final P0. Transmitting, by the NIC, enqueued P2 at t(P2).

Abstract: Systems, methods, and computer-readable media for load balancing using segment routing and application monitoring. A method can involve receiving a packet including a request from a source device to an application associated with a virtual address in a network, mapping the request to a set of candidate servers hosting the application associated with the virtual address, and encoding the set of candidate servers as a list of segments in a segment routing header associated with the packet. The method can further involve determining that a first candidate server from the set of candidate servers is a next segment in the list of segments, encoding the first candidate server in a destination address field on a header of the packet, and forwarding the packet to the first candidate server.

Abstract: A computing device running a local enforcement agent is configured to instantiate at least one application container at the computing device, where the at least one application container is part of a containerized application. The computing device is also configured to associate the local enforcement agent with the least one application container so that the local enforcement agent operates as an intra-application communication proxy for the least one application container. The local enforcement agent receives an intra-application Application Programming Interface (API) call that is sent to the at least one application container from a second application container that is part of the containerized application. The local enforcement agent is configured to analyze the intra-application API call for compliance with one or more security policies associated with the at least one container.

Abstract: Disclosed are systems, methods, and computer-readable storage media for adaptive telemetry based on in-network cross domain intelligence. A telemetry server can receive at least a first telemetry data stream and a second telemetry data stream. The first telemetry data stream can provide data collected from a first data source and the second telemetry data stream can provide data collected from a second data source. The telemetry server can determine correlations between the first telemetry data stream and the second telemetry data stream that indicate redundancies between data included in the first telemetry data stream and the second telemetry data stream, and then adjust, based on the correlations between the first telemetry data stream and the second telemetry data stream, data collection of the second telemetry data stream to reduce redundant data included in the first telemetry data stream and the second telemetry data stream.

Abstract: A method of controlling the distribution of content in a network is described. The content traverses the network in packets comprising a packet header including an address associated with the content, and a packet payload including the content. The method includes obtaining the address associated with the content from the packet traversing the network and analysing the address to extract information associated with the content carried in the packet payload.
