A method of, and apparatus for, network communication between a client computer initiator and a target data store. The method includes requesting, by the initiator, a data transfer session between the initiator and the target over a network. The request specifies quality of service parameters for the data transfer session. The method further includes receiving, from the target, a response accepting or denying the data transfer session based on the quality of service parameters; and establishing the data transfer session between the initiator and the target if the request is accepted. An advantage in communicating QoS requirements automatically on a per session basis between a client computer initiator and a target data storage resource is that QoS guarantees can be improved because the QoS determination can be carried out at the time the data transfer session is required. This enables the current access patterns on the storage resource to be monitored and an accurate determination regarding whether the QoS parameters of a desired data transfer session can be met.
