Patent number: 11757803Abstract: Certain embodiments enable application message delivery to be automatically guaranteed for all failover scenarios through use of a novel infrastructure layer that supports high availability (HA) messaging. The High Availability Application Messaging Layer (HAML) can guarantee delivery of application messages whether a failover occurs at one or both of the source and the intended destination of the message. The HAML may transmit messages to one intended destination, as unicast messaging, or to multiple intended destinations, as multicast messaging. In some embodiments, the HAML may be HA aware, which refers to the awareness of the HAML of the redundancy for all processing entities within a network device to ensure hitless failover at the network device. By moving support for HA messaging from individual applications to the HAML, as a common infrastructure layer across the processing entities, the individual applications do not need to implement additional software to explicitly support HA messaging.Type: GrantFiled: February 3, 2020Date of Patent: September 12, 2023Assignee: Avago Technologies International Sales Pte. LimitedInventors: Bill Ying Chin, Poongovan Ponnavaikko, Dan N. Retter, Mayur Mahajan

Patent number: 11456890Abstract: In one embodiment, a system for operating an autonomous driving vehicle (ADV) includes a number of modules. These modules include at least a perception module to perceive a driving environment surrounding the ADV and a planning module to plan a path to drive the ADV to navigate the driving environment. The system further includes a bus coupled to the modules and a sensor processing module communicatively coupled to the modules over the bus. The sensor processing module includes a bus interface coupled to the bus, a sensor interface to be coupled to a first set of one or more sensors mounted on the ADV, a message queue to store messages published by the sensors, and a message handler to manage the messages stored in the message queue. The messages may be subscribed by at least one of the modules to allow the modules to monitor operations of the sensors.Type: GrantFiled: July 16, 2019Date of Patent: September 27, 2022Assignee: BAIDU USA LLCInventors: Shengjin Zhou, Davy Huang, Tiffany Zhang, Dan N.

Patent number: 9967106Abstract: Certain embodiments of the present invention provide techniques that enable messages to be sent to a processing entity within a computing device without knowing the network address of the processing entity. In certain embodiments, instead of using the network address of the processing entity, a message can be communicated to the processing entity using information indicative of a role or state or function performed by the processing entity.Type: GrantFiled: October 26, 2015Date of Patent: May 8, 2018Assignee: Brocade Communications Systems LLCInventors: Bill Ying Chin, Dan N.
