Over the years TINE* has implemented numerous strategies for achieving high efficiency regarding data transport within a distributed control system. This was in fact essential in controlling a large machine such as HERA**. In modern times, a control system protocol suite must offer interfaces to many and sundry development platforms (not simply C++ and java) and it must support 'part-time' application developers, who might not be so well-versed in writing 'efficient' applications. This is an important point and easy to overlook until it is noticed that front end servers are struggling due to poor data flow models. For instance, a magnet server with 200 PSCs (Power Supply Controllers) might be accessed by a simple panel application which synchronously polls the readback values of all PSCs individually. The same server will have a much easier time if the client can be 'coerced' into acquiring the information asynchronously and as a multi-channel array of all values. TINE now offers various 'second-order' protocol features which go a long way in not just allowing but 'enforcing' efficient data transfer. We shall describe some of these features in this article.
