  • Patent number: 10146678
    Abstract: Test bundling and batching by a test execution framework may be customized in accordance with test suite requirements for testing platform implementations on network-connected, resource-limited devices. Tests, test data and test results may be communicated in bundles or batches. Multiple tests may be bundled into a test application bundle and communicated over a single data connection. Test data for the tests in a bundle may be packaged into a single batch and transferred using a single data connection. Similarly, results from executing the tests in a test application bundle may be batched and transferred together over a single connection. Additionally, a custom user interface may be utilized to allow for customizing the test bundling policy for individual test suites. Providing the ability for a user to customize the test bundling policy may significantly reduce the number of data connections required during test suite execution.

The method further provides, if the content qualifies for transmission over the diverse wireless links, generating a first alternate packet that contains a first portion of the content and a second alternate packet that contains a second portion of the content. The method further provides transferring the first alternate packet over the first wireless link for delivery to the destination and transferring the second alternate packet over the second wireless link for delivery to the destination.

  • Patent number: 9407449
    Abstract: Methods and systems for hardware-accelerated packet multicasting are provided. According to one embodiment, a first packet to be multicast to a first destination and a second packet to be multicast to a second destination are received. The first and second packets are classified in accordance with different virtual routers (VRs) of multiple VRs instantiated by a virtual routing engine (VRE) of a virtual routing system by determining a first selected VR to multicast the first packet and a second selected VR to multicast the second packet. For each of the first and second packets: a routing context of the VRE is switched to a routing context associated with the selected VR; at least a portion of the packet is read from one of multiple multicast address spaces associated with the selected VR; and the packet is forwarded to the destination.

  • Patent number: 9331956
    Abstract: The disclosure discloses a processing method for a stateful Path Computation Element (PCE) and a stateful PCE. The method includes: the stateful PCE completes path computation of the stateful PCE, and reserves or locks resources needed by a computed path; the stateful PCE receives a first notification message, wherein the first notification message is used for notifying the stateful PCE of a path which is unsuccessfully established during a Resource Reservation Protocol (RSVP) signalling procedure or a path which is successfully deleted during an RSVP signalling procedure; and the stateful PCE releases resources needed by the path notified by the first notification message. The disclosure improves the real-time property and accuracy of the resource information which the stateful PCE is aware of, and the accuracy of the path computation of the PCE, so as to avoid resource conflict.
