Abstract: A domain manager configured to manage and/or configure an audio-video (AV) system but not directly participate in networked media transmission or clock synchronization. The domain manager may include a database; an endpoint manager configured to communicate with the database, the endpoint manager being configured to setup and maintain secure connections to and from media devices and controllers; and at least one management module configured to communicate with the database and provide services to the media devices and controllers. In embodiments, the at least one management module may include at least one of a manager for managing credentials and grouping devices into domains, a device directory for managing device registrations and lookup, and an access controller for managing and/or evaluating access control policy.

Abstract: A method of avoiding deadlock during managing storage of items in a network (102) of heterogeneous storage devices (104,106,108). The method firstly detects (402) a storage event. Detection is effected by the local storage device and then the method obtains input information (404) having parameter values related to the item and the heterogeneous storage devices (104,106,108). The method then processes (406) the input information to determine a storage assignment, for storage of the item on one or more of the heterogeneous storage devices (104,106,108). The assignment is based on item-device suitability determined from a combination of at least one item selection rule and rules preventing deadlock.

Abstract: A method, a network access point and a communication system are disclosed for admitting data flows corresponding to new service requests to a multiple access network. The method includes the steps of receiving a service request having Quality of Service (QoS) requirements from a network node (410), calculating the effective bandwidth required by a data flow corresponding to the service request based on an average packet size of the data flow (420), determining the maximum capacity of the network (430), and admitting the data flow corresponding to the service request (445) if the network has sufficient capacity to accommodate the effective bandwidth required by the data flow. The average packet size of a data flow corresponding to the service request can be determined from the service request for calculating the effective bandwidth required by the data flow. The maximum capacity of the network can be determined based on the number of transmitting nodes in the network.
