摘要： Techniques are disclosed herein for managing network bandwidth in a distributed system having multiple endpoints that upload data to a central server or server cluster. One embodiment provides a computer-implemented method that includes receiving a logical topology of the network that is determined based on network measurements. The method further includes generating a tree having links of the logical network topology as nodes, and allocating bandwidth during a traversal of the tree to obtain a bandwidth allocation scheme for the endpoints uploading data. In addition, the method includes controlling bandwidth consumption by the endpoints based on the determined bandwidth allocation scheme.

摘要： Techniques are disclosed herein for managing network bandwidth in a distributed system having multiple endpoints that upload data to a central server or server cluster. One embodiment provides a computer-implemented method that includes collecting network measurements from traffic flows in a network over which the endpoints upload the data to the central server or server cluster. The method further includes determining a logical topology of the network based on the network measurements, and solving an optimization problem to determine a bandwidth allocation scheme for the endpoints uploading data, wherein capacity of links in the logical topology are constraints in the optimization problem. In addition, the method includes controlling bandwidth consumption by the endpoints based on the determined bandwidth allocation scheme.

摘要： A method to improve virtual desktop infrastructure (VDI) user experience includes providing a user access to a first virtual desktop executing a first set of applications and having a first virtual machine (VM) configuration, collecting VDI performance metrics associated with the first virtual desktop, detecting a problem from the VDI performance metrics, and changing a first remote display protocol configuration to address the problem. The method further includes collecting the user's feedback, training a model with the first VM configuration, the first set of applications, the user's feedback, and the first remote display protocol configuration, receiving a second VM configuration for a second virtual machine providing a second virtual desktop and a second set of applications on the second virtual desktop, using the model to generate a second remote display protocol configuration for the second virtual desktop, and configuring the second virtual desktop with the second remote display protocol configuration.

摘要： Techniques are disclosed herein for managing network bandwidth in a distributed system having multiple endpoints that upload data to a central server or server cluster. One embodiment provides a computer-implemented method that includes receiving a logical topology of the network that is determined based on network measurements. The method further includes resolving a convex optimization problem over the logical topology to determine a bandwidth allocation scheme for the endpoints uploading data. In addition, the method includes controlling bandwidth consumption by the endpoints based on the determined bandwidth allocation scheme.

摘要： A method for log analysis includes receiving log outputs from an application and generating a log file by recording the log outputs in the log file and, for each log output in the log file, attaching a log context record to the log output. The log context record is encoded with a call stack having stack frames and one or more variables in the stack frames. The method further includes grouping the log outputs in the log file based on their log context records.
