Abstract: Methods and apparatus are provided for improving the configuration, management, and distribution of quality of service information in a fibre channel fabric using zoning mechanisms. Configuration of Quality of Service (QoS) information is made easy by using zones as a classifier for flows. QoS information is included in zone objects, thereby using the existing zone distribution mechanism to distribute QoS information. Devices not part of any zones are placed automatically in the default zone with a default QoS priority level. QoS information for a particular packet is available as soon as the zoning information is obtained.

Abstract: In a node of a data communication system with a number of nodes, in which data communication system isochronous and asynchronous data is exchanged through a serial data bus structure, multiple link layer interface circuits are coupled to a single physical layer interface circuit. The physical layer interface circuit has an external port through which the physical layer interface circuit is connected to the serial bus structure. The physical layer interface circuit is coupled to the link layer interface circuits through bi-directional switches. A logic circuit controls the bi-directional switches and, in dependence of configuration information stored in configuration registers of the link layer interface circuits and its own programming, the logic circuit controls routing of isochronous and asynchronous data streams from the link layer interface circuits to the physical layer interface circuit, and from the physical layer interface circuit to the link layer interface circuits.

Abstract: Techniques are provided to move the services performed on one device to another device in a cloud computing system for a variety of reasons including failure, maintenance or upgrade of the device. A notification is received that services performed by an impacted device in a domain of a plurality of hierarchical domains need to be moved. A determination is made as to whether there are replacement resources available in the domain to perform the services, and if so, the replacement resources are automatically rendered to perform the services. The process continues to higher level domains that have a view into the capabilities of subordinate domains in order to determine where to move the services within the cloud computing system.
