Research on distributed processing of network monitoring information flow based on Hadoop Chen Guoliang A new method of distributed cluster processing based on Hadoop cloud computing framework is proposed for the monitoring of information flow of large data sets in intelligent power grid dispatching system. By analyzing the characteristics of information flow in power grid monitoring system, extracting 3 kinds of critical information flow, using the Distributed File system HDFs and Mapping aggregation model Map/reduce, establishing the distributed processing platform of Cluster group, and realizing the high efficient parallel processing of the monitoring data. Taking the data set of section measurement record of a distribution network as an example.

TOMP2P is a peer-to-peer, Advanced distributed hash Table (DHT) that stores key value pairs of data repositories for multiple values. Each value has a table (disk-based or memory) for the data to store its own value. A single value can be used to query or update minor keys. The underlying framework of communications uses Java NIO to handle multiple concurrent connections. TOMP2P Main Features: non-blocking IO Java6 implement distributed hash table DHT similar to Kademlia DHT based on XOR iterative routing criteria: put, ...

It is said that there is no point in improving supercomputers at a rapid pace in distributed computing, such as HTC's power to give program, which allows your phone to gain the same computational capability as a supercomputer. Even so, the attempt to miniaturization the supercomputer is valuable, and in many scenarios we cannot guarantee that the device is connected to the cloud. Yesterday Nvidia CEO Huang unveiled a miniature version of the supercomputer Jetson TK1 at the company's GPU technology conference, Engadget reported. This board and Arduin ...

What is load balancing? Load balancing will distribute site traffic to multiple servers to help ensure that resources are used efficiently and that there is no server overload at every time. The allocation of requirements between server networks can limit time delays and increase response speed. With load balancing, if one or more servers are down due to failure or routine maintenance, the application will not necessarily be shut down completely. Instead, the remaining servers take the task directly. You can set up multiple servers locally, or you can choose a distributed server within the cloud network model. In a distributed computing cloud ...

Research and optimization of distributed file system based on cloud storage University-ocean in this paper, based on the systematic and comprehensive study and summary of the development status and characteristics of distributed storage system, the advantages and disadvantages of several common distributed storage System architectures are analyzed emphatically.
