The method includes providing a first probe request in a first time slot on a first channel using the first radio, and receiving a first probe response in a second time slot on the first channel using the second radio.

Abstract: 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.

Abstract: One embodiment of the present invention provides a switch system. The switch includes a port that couples to a server hosting a number of virtual machines. The switch also includes a link tracking module. During operation, the link tracking module determines that reachability to at least one end host coupled to a virtual cluster switch of which the switch is a member is disrupted. The link tracking module then determines that at least one virtual machine coupled to the port is affected by the disrupted reachability, and communicates to the server hosting the affected virtual machine about the disrupted reachability.

Abstract: Systems and methods of communicating in a network use rate limiting. Rate limiting units (either receive side or transmit side) can perform rate limiting in response to a) a maximum number of bytes that can be solicited over a first period of time is exceeded, b) a maximum number of bytes that are outstanding over a second period of time is exceeded; or c) a maximum number of commands that are outstanding over a period of time is exceeded as part of CMD_RXRL. The CMD_RXRL can have three components (a) max bytes, b) outstanding bytes, c) outstanding commands. TXRL contains the component of max bytes or maximum number of bytes that can be transmitted over a third period of time to match the speed of a receive link, or any node or link through the network/fabric.

Abstract: Methods and systems for early identification of bitrates for segments in adaptive bitrate streaming can allow the server to begin processing or transcoding content as necessary for delivery, reducing processing and transmission latency. In a first aspect, a client may request a second segment before the first segment has been completely received. The server may begin any transcoding processes for preparing the second segment, and once the server has completed sending the first segment, the server may begin transmitting the now-prepared or partially prepared second segment. The server can then transmit the first and second segment contiguously, with essentially no network dead time. In a second aspect, the client may transmit an early notification of parameters for the request of the second segment, allowing the server to begin transcoding. The client may subsequently request the already-prepared or partially prepared second segment, similarly reducing request-response processing latency.
