Chord aims to provide an algorithm that can quickly locate resources in P2P networks. It does not care about how resources are stored. It only studies the acquisition of resources at the algorithm level, therefore, the chord API simply has only one set and get.1.

Chord-Based Structured P2P platform
The Chord protocol describes how to locate the storage location of a given value, how to add a new node to the system, and how to recover from the failure (or departure) of an existing node. The core of chord is to provide a fast distributed Hash function to map values to the nodes where they are stored. The hash function balan

chances of the entire system crash will be much lower. However, the Network may crash.
In the current research results, Chord, pastry, can, and tapestry are commonly used to construct a structured P2P Distributed Hash Table System (DHT ).
The main idea of DHT is: first, each file index is represented as a (K, v) pair. k is called a keyword and can be a file name (or other description of the file) is the IP address of the node where the file is stored

DescriptionIn a highly modernized fishing village, inhabitants there make a living on fishery. Their major tools, fishing nets, is produced and fixed by computer. After catching fishes all time, together with plenty of fishes, they would bring back the shabby fishing nets, which might be full of leaks. Then they has to inspect those nets. If there exist large leaks, they has to repair them before launching out again. Obviously, the smaller the leaks in the fishing nets is, the more fishes they w
The secant METHODIn numerical analysis, the secant method was a root-finding algorithm that uses a succession of roots of secant lines to be tter approximate a root of a function f. The secant method can be thought of as a finite difference approximation of Newton ' s method. However, the method was developed independently of Newton's method, and predated the latter by over 3,000 years.1 /*2 * =====================================================================================3 *4 * Filename:
