Conventional network software requires the server to send a copy of the same message to thousands of users. Together, these technologies are expected to help telecommunications service providers rapidly deploy new services and generate new revenues.
Continuous updates require many repeated requests to determine if content has changed.
Each request must receive a separate and distinct response, which creates unnecessary duplication and wastes compute cycles on the server. As more and more users make requests, the result is significant delays and network congestion. The publish and subscribe model significantly eases the traffic problem. Publish and subscribe allows information to be distributed as it becomes available. Subscribers receive the content in which they've registered an interest, without specifically connecting to a site or an application.
