Abstract: A streaming device may request and download multi-layer video segments based on a number of factors including the artistic interest associated with the video segments and/or the status of a buffer area managed by the streaming device. The multi-layer segments may be coded using scalable coding techniques or a combination of scalable coding and simulcast coding techniques by which each of the video segments may be coded into one or more representations of different qualities and/or bitrates. When requesting the multi-layer segments, the streaming device may ensure that the fullness of the buffer area falls between a buffer underflow threshold and a backfilling threshold under various network conditions. The streaming device may estimate the available network bandwidth in order to facilitate the scheduling decisions. The streaming device may consider the artistic interest associated with the video segments during scheduling and may give priority to those segments with higher artistic interest.

Abstract: A programmable network interface for a server includes at least one memory storing connection parameters for previously active Non-Volatile Memory express over Fabric (NVMeoF) connections with different NVMe nodes. An NVMeoF connection request is received from an NVMe node, and it is determined whether the NVMe node is associated with connection parameters stored in the at least one memory. In response to determining that the NVMe node is associated with connection parameters stored in the at least one memory, a new NVMeoF connection is established for communicating with the NVMe node using the stored connection parameters. In one aspect, an address space of the server is partitioned, and an NVMe request queue is assigned to each partition of the address space. At least one address is identified in a received NVMeoF message, and an NVMe request queue is determined for performing an NVMe request included in the NVMeoF message.

Abstract: This document describes marker based approaches for a CDN to monitor and report on the amount of traffic that it is serving on behalf of content providers. They are particularly useful in hybrid delivery scenarios. Hybrid delivery scenarios means that a client may obtain content, such as a given multimedia stream, from one or more servers in the CDN, or from one or more peers in a peer to peer network. The amount of data served from the peer network is referred to herein as the “offload”, as delivery of that data has been offloaded from the CDN platform.

Abstract: A method for creating resources and a corresponding registration method, server, client device, and computer readable storage medium. The method for creating resources includes: receiving a registration request; determining a registration type corresponding to the registration request; creating a resource corresponding to the registration type on the basis of the registration type.

Abstract: Techniques are described for providing a simultaneous, multi-device user experience that employs computing devices with varying capabilities for data input and/or data output, using a microservice-based architecture. A user may register multiple devices with a service, which determines capabilities of the devices for data input and/or output. During a communication session involving the user and another user, such as a service representative, the service may receive input data collected through device(s) and/or provide output data to be presented on the same or other device(s), where such data input and data output is received and provided according to the input/output capabilities of the various devices. The data input and/or output may switch from device to device during a session. In some instances, data may be replicated for presentation through multiple devices simultaneously. Interactions with each device may be through a microservice that is associated with the device and/or its device type.

Abstract: In some implementations, a computing system can reduce startup delays for presenting remote media items. For example, when a user requests media content from a media service, the computing system can include information about the first media item to be played in the initial startup messages to reduce the number of roundtrips needed between client and server devices to present the first media item. A media item can include an introductory asset. The introductory asset can be a portion of the full media item that can be decrypted with a local key or not encrypted at all so that a media client can receive and start presenting the introductory media asset quickly while the full media item is being processed by the media client. In some implementations, the system can remove leading silence from the media item so that the amount of delay perceived by the user is reduced.

Abstract: Methods and systems for early identification of bitrates for segments in adaptive bitrate streaming can allow the server to begin processing or transcoding content as necessary for delivery, reducing processing and transmission latency. In a first aspect, a client may request a second segment before the first segment has been completely received. The server may begin any transcoding processes for preparing the second segment, and once the server has completed sending the first segment, the server may begin transmitting the now-prepared or partially prepared second segment. The server can then transmit the first and second segment contiguously, with essentially no network dead time. In a second aspect, the client may transmit an early notification of parameters for the request of the second segment, allowing the server to begin transcoding. The client may subsequently request the already-prepared or partially prepared second segment, similarly reducing request-response processing latency.

Abstract: A non-transitory computer readable storage medium has instructions executed by a processor to receive network session information from network monitoring devices distributed throughout an enterprise network. The network session information characterizes communications between a client device within the enterprise network and a server external to the enterprise network. The network session information is transformed into vectors of network communication session parameters. The vectors are combined into different time series of data. A similarity measure is computed between the different time series of data to detect unique sessions between the client device and a middlebox network device within the enterprise network or unique sessions between a middle box network device within the enterprise network and the server. The unique sessions are evaluated to infer relationships between networked devices within the enterprise network.

Abstract: Some embodiments provide a method for associating data message flows from applications executing on a host computer with network interfaces of the computer. The method of some embodiments identifies a set of applications operating on a machine executing on the host computer, identifies candidate teaming policies for associating each identified application with a subset of one or more interfaces, and generates a report to display the identified candidate teaming policies per application to a user. In response to user input selecting a first teaming policy for a first application, the method generates a rule, and distributes the rule, to the host computer to associate the first application with a first subset of the network interfaces specified by the first teaming policy.
