Parameterized quality of service in a network

摘要

A method of performing a network transaction at Layer 2 comprising the steps of (a) receiving at a network coordinator a Layer 2 request to perform a network transaction from a first node; (b) transmitting a first Layer 2 message from the network coordinator to at least one node connected to the network in response to the request; (c) receiving, at the network coordinator, a response to the first Layer 2 message from at least one node connected to the network, the response including network resource allocation data; (d) determining the capabilities of the network at the network coordinator based on the received response to the first Layer 2 message; and (e) allocating network resources to perform the network transaction if the network coordinator determines there are sufficient network resources to perform the transaction.
