Abstract: Methods, systems, and computer-readable media for providing reliable switching between different transport protocols (e.g., TCP and UDP) are presented herein. In some embodiments, a computing platform may stop transmission over a transport protocol. Subsequently, the computing platform may synchronize buffers between a client and a host. For example, the buffer may include acknowledgments for undelivered reliable packets between the client and the host. Next, the computing platform may resume transmission over a different transport protocol. In some embodiments, when establishing an initial connection between a client and a host, connections may be attempted in parallel over multiple transport protocols. After a connection over a first transport protocol is established, if a connection is later established over a second transport protocol, the connection may be transitioned to the second transport protocol. Also, ticketing semantics may be preserved in the switch between the different transport protocols.

Abstract: A method for a node to become a member of a cluster includes, when the node is in an initialization state, refraining from starting any service for the cluster, rejecting any reconfiguration request from a coordinator of the cluster, and determining if a local copy of a member list is out-of-date. When the local member list is up-to-date, the method includes advancing to an observer state or a participant state depending on if the node is in the member list. When the local copy of the member list is out-of-date, the method includes waiting to receive the member list, updating the local member list to be equal to the member list, persisting the local member list, recording the local member list as up-to-date, and advancing to an observer state or a participant state depending if the node is in the member list.

Abstract: In a method of using an observation platform to determine relative expertise of enterprise employees, a computer system of the observation platform monitors communications from and to a plurality of communication devices which have been routed through a radio access point associated with the computer system.

Based on the packet identifiers in each time slot, the kernel module can pull the data packet having the packet identifier directly from the ring buffer and send each packet to the network interface controller for transmission as part of a media stream over a network to a media consuming device.

Abstract: An approach is provided that automatically classify network traffic of web applications and services based on a dynamic analysis. The approach scans a resource that corresponds to a named network application and receives, as a result of the scan, network resource identifiers that are accessed by the named network application. Network traffic between users and network resources is monitored, with the monitoring resulting in a set of visited network resource identifiers. The set of resource identifiers is found by matching the visited network resource identifiers with the network resource identifiers returned by the scan. Each of the set of resource identifiers is then matched with the named application.

Abstract: A system and method for content distribution are provided. A content provider generates a network topology having one or more subnetworks made up of content sources. The content provider segments content, such as applications, into segments for distribution. The content provider then distributes the content such that for each identified subnetwork, each content segment is distributed to a content source. Subsequent, client computing device requests for content can be serviced by selecting a content source in a particular subnetwork selected for delivering the requested content to the client computing device to minimize traffic flow of the requested content through the nodes of the distribution network.
