  • Publication number: 20190334812
    Abstract: A mobile accelerator system includes point of presences (POPs) that includes an entry POP. The entry POP receives a query to a content server from a mobile device via a dedicated transport channel. The entry POP determines a direct connection score for a direct connection between the mobile device and the content server that does not traverse the mobile accelerator system. The entry POP determines a POP connection score for a connection between the mobile device and the content server through the entry POP and a candidate exit POP. The entry POP determines a dynamic path ranking based on the direct connection score, the POP connection score, and other POP connection score(s) associated with other candidate exit POP(s). The entry POP determines at least a portion of a dynamic path between the mobile device based on the dynamic path ranking and routes data transfers through that dynamic path.

  • Publication number: 20190324761
    Abstract: A system on chip (SOC) is provided. The system on chip includes a non-volatile memory, an exception detector, and a processor. The non-volatile memory stores a first bootset in a first region, the first bootset including a booting operation bootloader for a first booting operation and stores a second bootset in a second region that is different from the first region. The exception detector is activated after execution of an initialization bootloader, detects an exception occurrence in the system on chip, and generates a reset signal in response to the exception occurrence that is detected. The processor performs a second booting operation by using the second bootset in response to the reset signal received from the exception detector during the first booting operation performed by using the first bootset.

  • Patent number: 10349304
    Abstract: Techniques that provide for intelligent routing of mobile device traffic using custom protocols or protocols that are otherwise unsuitable for optimization by a mobile accelerator system are discussed herein. Some embodiments may include a point-of-presence (POP) configured to manage a dynamic listing defining a listing of content server associated with traffic that is not suitable for being optimized. Upon receiving traffic from the content server, the POP may be configured to access the dynamic filter, and route data transfers between the mobile device and the content server to bypass the mobile accelerator system when indicated by the dynamic filter. The POP may be further configured to update the dynamic filter, such as by adding or removing content servers based on parsing associated traffic for optimization suitability and/or protocol use.
