<p>A method of transmitting data in a communications system with protocol layers comprising communications protocol layers and an application layer corresponding to a data transfer protocol to which the data is subjected; the data being transmitted with a level of error protection that is varied as a function of the category of the data according to a priority specification provided by a user. In one embodiment the data is transmitted between a client and a server. The priority specification can be static, for example in the form of a configuration table, or can be varied dynamically. The level of error protection can be further varied dependent on the category of the data responsive to communication link conditions of said communications system. Also described are an apparatus for transmitting data in a communications system; an apparatus for allocating a varying level of error protection to data to be transmitted in a communications system; and an apparatus for providing a priority specification for determining varying levels of error protection to be allocated to the transmission data in a communications system.</p> |
