Abstract: Methods, computing systems and computer program products implement embodiments of the present invention that include configuring multiple servers coupled to a network as a software defined storage (SDS) grid. A first given server receives, via the network, an input/output (I/O) request from a host computer, and determines a location of data associated with the I/O request. In some embodiments, each of the servers maintains a local grid data map that store locations for all data managed by the SDS grid. Upon identifying, in its respective local grid data map, that a second given server is configured to process the I/O request, the first given server forwards the I/O request to the second given server for processing, and upon receiving a result of the I/O request from the second given server, the first given server conveys the result of the I/O request to the host computer.

Abstract: Time to live (“TTL”) values are determined based on one or more factors. The TTL values may be included in responses to requests for resources, thereby affecting the frequency of subsequent requests. This dynamic determination of TTL values may provide resilience to system load, for example by using longer TTL values when the system is under greater load in order to reduce the rate at which subsequent requests are received. A dynamic TTL service may calculate a TTL value based on one or more factors, such as overall system load, resource load, hardware load, and/or software load. In various embodiments, a dynamic TTL service may act natively within a service, within a system framework, as a proxy, as a cluster, and/or as a broker.

Abstract: Optimizing allocation of multi-tasking servers is provided. A schedule that identifies a plurality of time periods is received. The schedule associates each server of a plurality of servers with at least one time period. Performance characteristics, including a multitasking threshold, of each server of the plurality of servers is determined. A simulation of the plurality of servers is performed to determine a service level of the simulation. A workload identifying a plurality of incidents is received. Each incident is allocated to a server. One or more performance metrics of each time period is determined. The service level of the simulation is determined based, at least in part, on the one or more performance metrics of each time period. The schedule is optimized based, at least in part, on at least one of the service level and a target service level.

Abstract: A method to enhance a subjective quality of experience for an application may include receiving network performance data, the data representing at least one observable application characteristic, and the subjective quality of experience (QoE) survey data. The method may further include generating at least one perception model which relates the data representing at least one observable application characteristic and the network performance data, and determining a QoE model which relates the subjective QoE survey data and the data representing at least one observable application characteristic. The method may further include inverting the at least one perception model and the QoE model to obtain a relationship between network performance parameters and the at least one observable application characteristic, and adjusting network parameters based on the at least one inverted perception model and inverted QoE model.

Abstract: Performance data received from interrelated communication devices is analyzed to determine the current operating state of the device and based on the current operating state a variable associated with replacing the device is determined which is implemented in the determination of a dynamic user-specific replacement schedule for the interrelated communication devices.

Abstract: Throttling for network requests may be implemented. A request processing balance may be provided for processing received network requests for a given period of time. As network requests are received, processing costs may be determined for the network requests. Processing costs may be determined on-the-fly based on processing times, resources consumed, or costs incurred to process the network requests at additional systems, in some embodiments. The request processing balance may be updated according to the determined processing costs of received network requests. Network requests may be throttled based on the current request processing balance. In some embodiments, an estimated processing cost may be determined and compared with the current request processing balance to determine whether to throttle the network requests.

Abstract: Systems and methods for a network, wherein a network device sends one or more pieces of a fragmented message to another network device via a network, and the network device that has received the one or more pieces of the fragmented messaging sends one or more acknowledgments of the receipt of the one or more pieces of the fragmented message to the sender of the fragmented message.

Abstract: A computer-implemented system and method for enabling publishing/sharing of content to a web page by sending an email to a centralized email address. This is accomplished with an email server that employs a modular array of software inclusive of a Message Monitoring System (MMS) software application, an interpretation layer software module (the “Interpeter Module”), and Message Posting System (MPS) software application. The MMS software automatically extracts messages, invokes the Interpeter Module to detect, the sending format and to provide necessary reformatting. The MMS software then invokes the MPS software which posts the reformatted message content to a designated web page at the assigned URL. Any user registered or not can post any content to a web page anytime simply by sending, the content to a singular email address (e.g, Post@abovo42.com). The present solution is easy to use and enables real-time publishing/sharing by multiple users.

Abstract: A technique provisions a computerized device with a main operating system. The technique involves loading, while the computerized device operates as a preboot execution environment (PXE) protocol client, a limited boot image from a PXE server over a network (e.g., booting the limited boot image using the trivial file transfer protocol or TFTP). The technique further involves executing the limited boot image loaded from the PXE server to operate the computerized device as an advanced protocol provisioned client. The technique further involves downloading, while the computerized device executes the limited boot image to operate as the advanced protocol provisioned client, the main operating system into local memory from an operating system server over the network (e.g., booting the main operating system using the file transfer protocol or FTP). The computerized device may store a copy of the main operating system in a local non-volatile cache if available.

Abstract: The invention relates to a method and a communications arrangement for operating a communications connection between a communications terminal device (KE1) associated with a first participant and at least one first terminal device (KE2) associated with a second participant. For a process running on a second terminal device (RE1) integrating with a first communications terminal device (KE1) to be operated by the first participant, said process being free of functions for controlling the communications connection, at least one piece of information that is reproducible on a terminal device is extracted from a process-produced output (P1) to the second terminal device (RE1). Further, upon initiation of the communications connection between the communications terminal device (KE1) and the first terminal device (KE2), the reproducible information is transmitted to at one of the least one terminal devices (KE2, RE2) associated with the second participant.

Abstract: The present disclosure is directed towards systems and methods routing network packets between multi-core intermediaries. A processor of a plurality of processors on a client-side intermediary device may receive a packet from a client device. The processor may be identified by a core identifier. The processor may calculate a first set of source port addresses based on a first key and the core identifier. The processor may identify a target server-side intermediary device and a target processor based on data received with the packet or metadata received from the target server-side intermediary device. The processor may calculate a second set of port addresses based on a second key and the target core identifier. The processor may identify a port address common to both the first set and second set of port addresses. The processor may replace the original source port address in the packet with the identified port address.

Abstract: Techniques for streaming content, such as a video game or whiteboard application, to multiple different clients are described herein. In some cases, differences may exist between characteristics of the different clients such as screen size, resolution, operating system, processors and memories and others. The different clients may be positioned in close proximity to one another or at remote locations with respect to one another. In some cases, different network conditions, such as available bandwidth, loss rates, latency, throughput and others, may exist for transmitting content to the different clients.

Abstract: A first device may receive a network information request that identifies a data object relating to a network device. The data object may correspond to or identify an attribute associated with the network device. The first device may determine that the attribute is a static attribute relating to a configuration of the network device. The first device may determine whether a second device stores the data object. The second device may store data objects corresponding to static attributes. The first device may selectively obtain the data object from the network device or from the second device based on determining whether the second device stores the data object. The first device may provide the data object based on the network information request.

Abstract: A distribution apparatus packetizes streaming data of a variable bit rate, and distributes the resulting data to a plurality of playback apparatuses. The distributed streaming data is transferred from one playback apparatus to other one or more playback apparatuses. One playback apparatus measures the communication quality between the one playback apparatus and each of the other playback apparatuses of transfer destinations. One playback apparatus redivides the received streaming data into packets based on a playback data amount for each unit playback time in the received streaming data and on the measured communication quality and transfers the resulting streaming data.

Abstract: Provided is an end-to-end flow control management for a system on chip interface. As tokens are injected into agents arranged in a computer network the input point for the token is dynamically changed such that tokens are not always injected into the same agent. Additionally or alternatively, as tokens are injected into a token ring, the tokens are initially not activated until a predetermined event occurs (e.g., after a specific number of hops). Additionally or alternatively, also provided is a free pool manager that can keep at least some high priority slots available by consuming lower priority slots first.

Abstract: Systems and method are provided for source-dependent address resolution. Multiple computing devices may be associated with identifiers, such as network names. These computing devices may further be associated with both internally and externally accessible network addresses. A source-dependent address resolution component may resolve a network identifier into an internal or external address based on a network of a requesting device. Specifically, a request for address resolution may be received from a source network, and be resolvable into an address of a target network. If the source network and target network are the same, an internal address of that shared network is returned. If the source network and the target network are different, an external address enabling external communication with the target network is returned. In some embodiments, determination of a source network may be facilitated based on a source port of a request.

Abstract: In one embodiment, a method includes receiving from multiple client devices real time click-stream data indicative of multiple users accessing a content object within a structured document displayed as a web page and storing presence information associated with each of the users in a server associated with a social-networking system. The method also includes identifying one or more of the users based on the presence information, where each of the identified users accessed the content object within a specified time period and the identified users are within a specified degree of separation from each other on the social-networking system. The method further includes sending, to the client device associated with a first user of the identified users, instructions to modify a representation of the web page to include a messaging interface including presence information associated with one or more second users of the identified users.

Abstract: In some examples, a controller provisions services for transporting packet flows within a network. A controller service provisioning module receives a service request that comprises a definition for a service to be provided by the network for a subscriber or a customer of the network. The service provisioning module determines a plurality of network resources of at least one network device to be configured to implement the service in the network and apply the service to the packet-based network traffic of the subscriber. A locking unit of the service provisioning module acquires a lock from a network-wide coordination repository that stores a software representation for each of the network resources, the lock providing exclusive configuration access to the service provisioning module for the network resources. The service provisioning module, only upon the locking unit acquiring the lock for the network resources, configures the network resources to provision the service.
