Abstract
A communications system may be used for transmitting and/or receiving data over a network. The communications system includes means responsive to requests for a desired quality of service specifying at least two quality of service parameters, such as bandwidth, latency, error rate, and so on, for determining whether or not the requested quality of service is available. The quality of service requests specify the desired quality of service in terms of logical expressions involving two or more of said at least two quality of service parameters. This allows, for example, a desired quality of service to accept a higher error rate if the available bandwidth is higher. In the preferred embodiment, each quality of service parameter is specified in terms of a range between minimum and a maximum acceptable values.
