In response to a map task distributed by a job tracker, a map task tracker executes the map task to generate a map output including version information. The map task tracker stores the generated map outputs. The map task tracker informs the job tracker of related information of the map output. In response to a reduce task distributed by the job tracker, the reduce task tracker acquires the map outputs for key names including given version information from the map task trackers, wherein the acquired map outputs include the map outputs with the given version information and historical map outputs with the version information prior to the given version information. The reduce task tracker executes the reduce task on the acquired map outputs.

A method for transmission of map/reduce data in a data center having a storage network (SAN), the data center including multiple servers deployed with a job tracker, map task trackers and reduce task trackers, the method comprising: in response to receiving a map task allocated by the job tracker, a map task tracker performing the map task and generating map task outputs; the map task tracker writing the map task outputs to the storage network; and in response to receiving a reduce task allocated by the job tracker, a reduce task tracker reading the map tasks outputs from the storage network.

Transmission of Map/Reduce data in a data center

A method for determining travel time of a vehicle on a road, wherein the vehicle is operable within a mobile communication network, comprising: collecting historical communication events of a mobile user in order to obtain travel samples, wherein the historical communication events indicate when the mobile user travelled along a monitored road; determining a cell handover sequence from the historical communication events; determining from the cell handover sequence, one of more road segments of the monitored road; determining the travel time of the one or more road segments according to the travel time samples; selecting, for an undetermined road segment of the monitored road for which the real-time travel time is not determined from the collected historical communication events, a candidate mobile user that is most likely to appear on the undetermined road segment; actively positioning the candidate mobile user to obtain positioning information; and returning to the step of collecting communication events of a mobile user currently on a monitored road with the active positioning as one communication event for the candidate mobile user, to determine the real-time travel time of the undetermined road segment.

Method and apparatus for traffic management

A method and system for operating a data center. The method includes, in response to a map task distributed by a job tracker, a map task tracker executes the map task to generate a map output including version information. The map task tracker stores the generated map outputs. The map task tracker informs the job tracker of related information of the map output. In response to a reduce task distributed by the job tracker, the reduce task tracker acquires the map outputs for key names including given version information from the map task trackers, wherein the acquired map outputs include the map outputs with the given version information and historical map outputs with the version information prior to the given version information. The reduce task tracker executes the reduce task on the acquired map outputs.

To reduce traffic between multiple servers in a presence system and improve the performance of the presence system, a method and device is provided for user-management in a presence system, and a presence system. The presence system comprises multiple presence servers communicating through a network, and said device for user-management comprises a combining means for combining multiple user sets among which there are the greatest correlations into a user set to be allocated; and an allocating means for allocating said user set to be allocated to one presence server which can contain said user set to be allocated. Through allocating multiple user sets among which there are the greatest correlations to a same presence server, communications among users in the user set are performed within a same presence server, reducing occupations for network resources and improving performance of the presence system.

A method and a system for processing an HTTP request. There is provided a method for processing an HTTP request, including: receiving an original HTTP request for accessing an instance of an application; modifying a domain name to be accessed; and sending the new HTTP request to a server of the application so as to access the instance of the application, wherein the domain name to be accessed by the original HTTP request and the new domain name correspond to a same IP address. This avoids various problems such as data confusion, data error, and use inconvenience in the related art occurring when a plurality of service instances of a same application run in a same hypertext transfer protocol session. A system for carrying out the above method is also provided.

Method and system for processing HTTP requests with multiple application instances

A method, apparatus, system, and computer readable medium for authenticating the identity of a caller. An authentication device authenticates a caller's identity based on received information of the caller and an identifier generation device generates an identifier containing the caller's identity. The authentication information is supplied to a mobile telephone user acting as a callee. Therefore, the callee knows the caller's identity, thereby providing a secure delivering channel.
