The company’s NetInjector platform comprises event routing software and end device agents, as well as an addressing system, that together allow application messages to be selectively pushed out to, potentially, hundreds of millions of users.
The advantage of publish/subscribe is that it reduces the traffic required by request/response delivery mechanisms such as the web, and allows data to be filtered and delivered to end user devices in real time.
Most publish/subscribe systems that exist are largely deployed in enterprise-level applications… There are no available implementations that can scale to the internet level, said PreCache CEO Dick Sullivan. But the next generation of applications people want to run on the internet [web services] require publish/subscribe… traditional request/response can’t handle that volume.
PreCache, which is funded by Sony, hopes to sell not only to software developers but also to service providers and device manufacturers that could help make the messaging system pervasive. Competitors include Kenamea Inc and KnowNow Inc, both of which are already providing services or shipping product.
