Problems solved by technology

[0005] Binding users to service nodes will lead to unbalanced email service loads that each service node needs to provide; binding users to storage nodes will result in low storage utilization of each storage node, and storage based on the local file system If you do not use RAID (Redundant Array of Independent Disk, Redundant Array of Independent Disks) technology for redundant backup, the storage reliability will be low, and if you use RAID technology or other dedicated storage devices, the cost will be higher

Embodiment Construction

[0020] The embodiment of the present invention aims at the problems existing in the existing distributed e-mail system, and provides a distributed e-mail system based on a cloud computing platform to realize load balancing of service nodes in the system and improve storage capacity of storage nodes in the system. utilization rate. Cloud Computing is the development and realization of Distributed Computing, Parallel Computing and Grid Computing. The basic principle of cloud computing is to distribute computing on a large number of distributed computers, rather than on local computers or remote servers, so that computers and storage systems can be accessed according to needs. Cloud computing divides the huge calculation processing program into multiple smaller subroutines through the network, and then sends the processing results to a group of computers for summary, calculation and analysis, and finally returns the results to the user.

Abstract

The invention discloses a distributed E-mail system and a service method thereof for implementing load balance of service nodes in the system and promoting storage utilization rate of storage nodes in the system. The distributed E-mail system comprises a distributed storage subsystem, a load balancing server and a service node, wherein the distributed storage subsystem consists of a plurality of storage nodes, and identity information and mail information of a user are stored in the storage nodes; the load balancing server is used for receiving E-mail service request sent by the user, determining the service node providing E-mail service for the user according to the current load information of the service node and the set load balancing strategy, and forwarding the E-mail service request to the determined service node; and the service node is used for accessing the distributed storage subsystem to acquire the identity information of the user when receiving the E-mail service request, performing authentication on the user according to the acquired identity information, and providing the corresponding E-mail service for the user after the user passes the authentication.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a distributed email system and its service technology. Background technique [0002] The basic email services that the email system can provide to users include: support client software login to perform sending and receiving email operations, this service requires the email system to implement SMTP (Simple Mail Transfer Protocol, Simple Mail Transfer Protocol, ) session process, which can be called SMTP service; support client software to log in to perform extracting e-mail operations, and this service requires the e-mail system to implement a session process based on POP3 (Post Office Protocol 3, Post Office Protocol Version 3) with users , can be called a POP3 service; support users to access through a Web browser, and perform operations such as reading, editing, and sending e-mails, can be called a WebMail service. Distributed e-mail system is to deploy e-mail service in a ...
