Constant Contact Definition

Constant Contact – a pattern in which processes or components keep constant contact with each other so that data can be exchanged between them and these entities can react interactively. This is contrary to the case with the intermittently communication models whereby the major parties to the process have no continuous link that can, in turn, aid in the immediate transmittal and receipt of information sans delayer.

This is such a generic concept that is widely used in distributed systems, networking protocols, and in collaboration applications where a precondition is necessitated for timely communication. E.g. in a peer-to-peer network, it can mean the conditions under which the communicating nodes have to stay in an always-interactive state, sharing resources, exchanging messages, or synchronizing data. This case is just like in a client-server architecture where a normal persistent connection of the clients to the servers to serve rapid issuance and response of the requests are normally created.
