The invention discloses a method and
system for unifying a message space on large scale in real time. The
system is developed based on a cluster technology, has a self-configuration capacity and a load-balanced release / subscription function, and is established on
system architecture in which a cluster is taken as a unit; in the system architecture, proxy host computers participating in release / subscription are divided into various clusters; and the clusters are organized into a tree form for management and interact through cluster representatives. The system comprises a
client side, a routing module, a data module and a manager module, wherein the routing module is responsible for managing routing information and maintaining a subscription table; the data module is responsible for receiving subscriptions and notes from the
client side and sending and receiving information; and the manager module is responsible for maintaining a tree topology formed by the clusters. According to the method and system in the invention, high routing for subscription and notification can be realized, and the advantages of simple configuration, strong expansibility, balanced load and the like are achieved.
