Abstract: Methods, systems, and computer readable media for processing data units are disclosed. According to one method, the method occurs at a network interface of a computing platform having per data unit processing overhead that limits throughput of the network interface. The method includes concatenating multiple individual data units into a concatenated data unit (CDU), wherein the CDU includes a header portion for at least one of the multiple data units, processing the CDU as a single data unit rather than as multiple individual data units such that the CDU incurs processing overhead of a single data unit rather than that of multiple individual data units, and de-concatenating the CDU into the multiple individual data units.

Abstract: Reducing buffer space that is reserved when a VM attempts to write to disk. A shared memory maintains stored information available to all VM's, allowing translation between accessible to RSD's, independent of how that VM's storage is divided into VSD's. When a guest OS writes to a VSD, an “extent”, designating a location in the shared memory and amount of data to be transferred, which can be passed directly from the guest OS, through each element involved in translating the operation into one or more operations on RSD's, keeping copying to a minimum. No substantial changes need be made to the guest OS.

Abstract: A method, system, and program product for allocating a port for a connection by an application instance on a computer system is provided. The application instances used the port and a shared network address to connect to one or more application instances accessing the shared network address. A distributing stack creates at least one common table of available ports. Each table is associated with a different unique shared network address. When a request is received for a port to assign the shared network address, the distributing stack allocates a set of available ports. When a termination message is received, the distributing stack updates the common table of available ports associated with the shared network address. When a transfer from the distributing stack to a backup distributing stack is made, ownership of the common table of available ports is transferred to the backup distributing stack.

Abstract: Methods and systems may involve identifying metadata associated with a local application, and using an operating system-independent chat protocol to pass the metadata to a remote application. The metadata may include information to be presented to a user of a device executing the remote application, information to be used to locate more information for presentation to the user of the other device, information to be used to coordinate operation of multiple devices, and so forth. In one example, the metadata is passed using a protocol such as XMPP (Extensible Messaging and Presence Protocol).

Abstract: A client device communicates with a server to receive media streaming. The server detect a current media streaming session with the client device and determines a need to convey information regarding the ongoing media streaming session to the client device The server inserts a trigger in a hypertext transfer protocol (HTTP) response to a client device. The trigger is configured to indicate that a connection with the server is requested. The client device detects the trigger and verifies whether the server is a trusted server. After verifying that the server is trusted and the request is legitimate. The client device establishes a connection with the server and requests a message including information about the ongoing media streaming session. In response, the server sends a dynamic adaptive streaming over HTTP (DASH) message to the client device.

Abstract: The present invention extends to methods, systems, and computer program products for reconfiguring an acceleration component among interconnected acceleration components. Aspects of the invention facilitate reconfiguring an acceleration component among interconnected acceleration components using a higher-level software service. A manager or controller isolates an acceleration component by sending a message to one or more neighbor acceleration components instructing the one or more neighbor acceleration components to stop accepting communication from the acceleration component. The manager or controller can then shut down an application layer at the acceleration component for at least partial reconfiguration and closes input/output (I/O) portions. After reconfiguration completes, communication between the acceleration component and the one or more neighbor acceleration components can resume.

Abstract: Techniques are described for extending a two-way active measurement protocol (TWAMP) to enable measurement of service key performance indicators (KPIs) in a software defined network (SDN) and network function virtualization (NFV) architecture. The TWAMP extensions enable control messaging to be handled by a TWAMP control client executed on a centralized controller, and data messaging to be handled by a TWAMP session initiator executed on a separate network device. Techniques are also described for extending TWAMP to enable measurement of any of a plurality of service KPIs for a given service supported at a TWAMP server. The service KPIs may include one or more of keepalive measurements, round trip time measurements, path delay measurements, service latency measurements, or service load measurements. The TWAMP extensions for the service KPIs may be used in both conventional network architectures and in SDN and NFV architectures.

Abstract: Provided are methods and systems for distributing service sessions from a client device in a service data network. A packet of the service session is received by a forwarding node. The forwarding node determines whether the packet matches a service address associated with the service session. Responsive to the determining, a servicing node associated with the service address is selected based on a forwarding policy. The packet is sent to the selected servicing node. The servicing node determines whether the packet is a service request packet. A server is selected based on a service policy, wherein the server is configured to serve the service session. The packet is sent to the server. Before being received by a forwarding node, the packet is received by a gateway node. The gateway node determines whether the packet matches the service address and selects the forwarding node based on a notification.

Abstract: Mechanisms are provided for determining an event rate. The mechanisms sample a sequence of events to generate a set of sampled events. At least a subset of the sampled events have associated event sequence values indicating a position of the sampled event within the sequence of events. The mechanisms group the sampled events into a plurality of event groups based on a common characteristic of the events. The mechanisms determine, for each event group, sequence values of sampled events associated with the event group. The mechanisms calculate, for each event group, an estimated event rate based on the sequence values of the sampled events associated with the event group and the total number of events in the sequence of events.
