Embodiment Construction

[0060] In order to overcome the shortcomings in the existing Kademlia protocol that assume that all network nodes have the same capabilities and uniform connectivity, which do not match the characteristics of nodes in the actual network, and at the same time overcome the vulnerability of super nodes in the existing Kazaa protocol. For isolated shortcomings, this embodiment introduces the concept of super nodes on the basis of the existing Kademlia protocol, combines the advantages of centralized structure and fully distributed structured structure, and adopts NewKad protocol to realize routing query.

[0061] Each node in the Newkad network has a 160-bit randomly generated identification (ID) value as an identifier, Key is also a 160-bit identifier, and each computer that joins the Newkad network will be assigned a 160-bit space. Node ID value.

[0062] After a new node in the Newkad network joins the network for a period of time, according to the node performance (such as com...

Abstract

The invention discloses a method, device and system of voting super node, searching for network node or resource, it used to resolve problem of poor stability of network induced by unbalanced load and checking node in local part, in the scheme, the common node in network compares the property parameter value with said threshold value set by said condition based on condition that common node becomes to super node, and when it assures that property of this node fulfills the condition of super node, it sends message that the node becomes super node; and when searching for network node or resource, super node is first checked; adopting the invention can balance network load, increase the efficiency of searching for node and stability of network.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, device and system for electing super nodes and searching for network nodes or resources. Background technique [0002] With the extensive use of peer-to-peer P2P (Peer-to-Peer) computing software, the research on the topology of P2P networks has become more and more in-depth. At present, a large number of researches focus on how to construct a highly structured system. The new research The achievement is reflected in a fully distributed structured topology network using a distributed hash table DHT (Distributed Hash Table). [0003] The distributed hash table DHT uses the distributed hash algorithm to solve the structured distributed storage problem. The core idea of ​​the distributed hash algorithm is: hash the characteristics of the storage object (such as keywords) to obtain the key value (HashKey ), and perform distributed storage of objects according to the key v...
