Transmitting Information Across A Communications Network
First Claim
1. A method of transmitting information across a data network comprising at least one wireless network node,the information being capable of being transmitted across the network by means of data in a plurality of different formats including a first format and a second format, the second format being less demanding of the network than the first format by means of compromising, on the way in which the information is represented by the data,wherein the method comprises the steps of:
- a software application module running on computer hardware having information for transmission across a data network requesting the status of at least part of a route from a local node in the network to a destination node in the network, the route comprising at least one wireless link between the? two nodes within the network;
the software application module receiving an indication of the status of said at least part of the route; and
the software application module transmitting the data in a format chosen from the plurality of different formats in dependence on the indication of the status so received;
wherein the step of the software application module requesting the status of the route is performed before any attempt is made by the software application module to initiate the sending of the data to the destination node.

Abstract
Information is transmitted across a wireless data network, comprising a wireless link (100) from a software application module on a computer hardware device (112) to a computer hardware device (110) associated with a destination node in the network. The application requests (114) the status of the route across the network, such information being optionally provided by a decision engine (104) which has access to network status parameters, such as bandwidth, latency and link quality. The application receives (118) the status information and then, and preferably only then, transmits (120) the data in a format chosen from a plurality of different formats (of differing richness of information represented by the date in each such format) in dependence on the indication of the status so received.

9. A method of transmitting information across a data network comprising at least one wireless network node,
the information being capable of being transmitted across the network by means of data in a plurality of different formats including a first format and a second format, the second format being less demanding of the network than the first format by means of compromising on the way in which the information is represented by the data, wherein the method comprises the steps of: -
a processor analysing one or more characteristics of the status of at least part of a route from one node in the network to another node in the network, the route comprising at least one wireless link between two nodes within the network; the processor receiving a request from a software application module for an indication of which of the plurality of different formats data can be sent over said at least part of the route, in response, and in dependence on said one or more characteristics analysed by the processor, the processor indicates which format or formats, if any, of data that can be supported by said at least part of the route. - View Dependent Claims (10, 12, 15, 16, 17, 18)
