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.

Methods and systems for providing scene data of a virtual world. One method includes the following steps: receiving a request for downloading the scene data from a content requesting party, where the request includes (i) information on an object group in the scene data and (ii) Level of Detail (LoD) information on an object in the object group, packing LoD content of the object in the object group based on the information on the object group and the LoD information on the object, and transmitting the packed LoD content corresponding to the object group to the content requesting party.

Method and system for providing scene data of virtual world

The present invention describes a method and system for governing a physical device or application service in a real world through a virtual device in a virtual world. The physical device or application service registers at least one virtual adaptor of the physical device or application service to a virtual device broker. A user creates or composes the virtual device with the at least one virtual adaptor in the virtual device broker. The user commands to the virtual device through a user interface of the virtual device. The at least one virtual adaptor in the virtual device translates the command to a controlling signal to the physical device or application service. The controlling signal operates the physical device or application service according to the command to the virtual device.

A method and system for correlating out interactions, which occur due to one or a set of specific events, of an application, which is deployed in multiple adjacent tiers in an actual environment is described. First, a simulation environment corresponding to the actual environment is created. Then, specific events are led to the actual environment and the simulation environment. A pattern(s) of interactions, which are related with the specific events, between adjacent tiers in the simulation environment and a large number of interactions between adjacent tiers in the actual environment are obtained. Afterwards, interactions, which are related with the specific events, between adjacent tiers among the obtained interactions between adjacent tiers in the actual environment are correlated using a template of the obtained pattern(s) of interactions, which are related with the specific events, between adjacent tiers in the simulation environment as a template.
