Abstract: Various exemplary embodiments relate to a chaining of sequential functions associated with a service or application are considered. This approach relies on a centralized load balancer for reducing the load of inter-rack traffic in a data center. The centralized load balancer may include a memory configured to store a service data flow table; and a processor configured to: receive at the centralized load balancer, a path inquiry for a service data flow; determine which virtual machine to assign the service data flow, wherein at least two functions of a chain of functions required in the service data flow are to be performed on the same rack; and assign the service data flow to the determined virtual machine.

Abstract: The method includes retrieving subscriber and device information based on an application identifier and a GBR request indication, sending a message to a network entity, the message including a Quality of Service (QoS) Class Identifier (QCI), the QCI indicating an AGBR bearer is to be used for delivering content to a mobile unit, generating an AGBR bearer based on the QCI and a GBR setting and associating the content with the AGBR bearer. The method includes sending a message and the content to a network entity, the message including the QCI, scheduling the mobile unit on the AGBR bearer based on the QCI and communicating the content to the mobile unit based on the schedule.

Abstract: Various exemplary embodiments relate to a method for determining performance compliance of a cloud computing service implementing an application, including: receiving an application service performance requirement; receiving a cloud computing service performance requirement; receiving non-intrusive application performance data; determining that application performance does not meet the application service performance requirement based upon the received application performance data; determining that the cloud computing service provider does not meet the cloud computing service performance requirement based upon the received application service performance data; and determining that the cloud computing system not meeting the cloud computing performance requirement substantially contributes to the application performance not meeting the application service performance requirement.

Abstract: Various embodiments provide a method and apparatus of providing SPOF elimination for cloud-based applications that provides rules that support rapid elasticity, infrastructure maintenance such as, for example, software/firmware/hardware upgrades, updates, retrofit, and growth, and preventative maintenance such as, for example, cleaning fan filters and replacing failed hardware components. In particular, the SPOF elimination provided by the method and apparatus is based on network architecture and persistent storage considerations in addition to VM to host instance mappings.

The method includes sending a message and the content to a network entity, the message including the QCI, scheduling the mobile unit on the AGBR bearer based on the QCI and communicating the content to the mobile unit based on the schedule.

Abstract: A method, in a communications network, of collecting profile data related to at least a first type of service a user is supplied with and making that data available to at least a second different type of service the user is supplied with over the network.
