K-tree is a tree-like clustering algorithm. It is also called tree structure vector quantization (TSVQ). The goal of clustering analysis is in similar group objects. Each K-tree object represents a dimension vector space. All vectors in the tree must be the same number of dimensions. K-tree provides a scalable clustering method combining B+-tree and K cluster algorithms. Clusters can be used to solve signal processing problems, using machine learning, and other environments. It has also recently been used to solve problems in the Wikipedia documentation cluster. K-tree 0 ...

In the past Client-server, RPC framework hierarchies such as CORBA and RMI did not seek because such technologies could extend a stand-alone IPC (inter-process communication, interprocess communication) to communication between multiple computers, This is very helpful for extensibility, but for a variety of reasons these RPC frameworks have not been adopted by the industry on a large scale. In the era of cloud computing, more and more machines are needed for distributed communications, although they can be easily communicated by using the HTTP protocol.
