Problems solved by technology

[0003] For distributed systems with very large data volumes, the data in the routing table is also very large. Obviously, the centralized processing mode will cause performance bottlenecks
In a P2P system, multiple nodes need to be contacted for each query, and the data adjustment of nodes may affect the efficiency of the algorithm

Embodiment Construction

[0024] The invention will be described in more detail hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are illustrated.

[0025] figure 1 is an architecture diagram of an application scenario 100 according to an embodiment of the present invention. The application scenario 100 includes a distributor (Disp) 102 , a routing node (routeNode) 104 and a service processing node (valueNode) 106 . The distributor 102 is a process exposed to an external system, and is used for distributing and delivering messages, as well as calculating hashes for keys. According to an embodiment of the present invention, the routing table is a record consisting of pairs, as shown in the routing table structure in Table 1:

[0026] key 0

value 0

key 1

value 1

……

……

key n

value n

[0027] Table 1

[0028] Among them, the key can select a unique value in the message content ac...

Abstract

The invention provides a service routing method and a service routing system, relating to the technical field of data communication. The service routing method comprises the following steps: a distributor acquires hash function operation on a key assignment obtained from a received routing request so as to obtain an operation result; the distributor routes the routing request to a routing node corresponding to a serial number according to the serial number corresponding to the operation result in integer space divided by the number of nodes; the routing node researches the position information of the node corresponding to the key assignment in a routing table storing routing nodes according to the routing request; and the distributor routes the routing request to a service processing node appointed by the position information of the node according to the position information of the node. The storage of the routing table in the service routing system is in a distributed type, therefore, data can be unlimitedly and linearly extended, a system structure has no single point or choke point, a distributed type system with high capacity and large data size can be constructed, and the construction cost of the system is lower.

Description

technical field [0001] The invention relates to the technical field of data communication, in particular to a service routing method and system in a distributed system. Background technique [0002] In a distributed system, how to carry out message distribution and routing selection is a common concern. At present, two modes are commonly used to solve this technical problem: a distributed system that concentrates routing data on a small number of machines, such as HDFS (Hadoop Distributed File System, Hadoop Distributed File System), and NameNode stores routing information (file names and file block locations) etc.); P2P (peer to peer, peer-to-peer network) DHT (distributed hashtable, distributed hash table) protocol, such as Kademlia. [0003] For a distributed system with a very large amount of data, the data in the routing table is also very large. Obviously, the centralized processing mode will cause a performance bottleneck. However, in a P2P system, multiple nodes ne...
