Dynamic edge provisioning for core IP networks

Abstract: Effective edge capacity provisioning is an important architectural component of the emerging differentiated service Internet. We propose a set of dynamic provisioning algorithms, which are operational at the edge routers of a differentiated services core network. These edge mechanisms include: (i) ingress dynamic link sharing, which augments class based queueing techniques with bandwidth utility functions so that dynamic link sharing can be used to distribute bandwidth among traffic conditioners located at edge routers; and (ii) egress dynamic capacity dimensioning, which formulates bandwidth dimensioning at egress links to peering/transit networks taking into account measured core network traffic conditions. We demonstrate through analysis and simulation that the proposed edge provisioning architecture is efficient and effective at supporting user link sharing policies while taking into account the dynamics of traffic load measured in the core network.

Context-Aware Service Adaptation: An Approach Based on Fuzzy Sets and Service Composition

Abstract: With the pervasive use of mobile devices and the need for ubiquitous computing, the issue of ”context” now becomes a hot topic in human computer interaction research and development. Further, the interface of the interaction beyond the desktop is moving from humans vs. computers to humans vs. context-aware environments. This leads the context to constitute an underlying part of service behavior, especially when interaction with end-users is involved, and consequently this demands the context-aware computing systems to be designed to automatically adapt its behavior to changing environment. Thus, pervasive computing applications need to be more autonomous and sensitive to context. However, in real-life systems context information is naturally dynamic, vague and complex, which lead to an inexact match between provided and required service capabilities. In this vision, we propose in this paper a three-phases adaptation approach: firstly we select the suitable services to the current context and we recommend them to the adaptation process, in the service adaptation phase we perform adaptation by using fuzzy sets represented with linguistic variables and membership degrees to define the user's context and the rules for adopting the policies of implementing a service. Finally we deal with the complex requirements of the user by the composition of the obtained adaptable atomics services.

System and method for providing, by a plurality of schedulers, differentiated service to consumers of distributed resources

Abstract: One embodiment of the present invention provides a method comprising assigning a first weight to a first consumer and a second weight to a second consumer. The method further comprises receiving at a first scheduler a request for service by a first resource to the first consumer; receiving at a second scheduler a request for service by a second resource to the first consumer; and receiving at the first scheduler a request for service by the first resource to the second consumer. The method further comprises scheduling, by the first and second schedulers, service from the first and second resources to the first and second consumers, wherein the scheduling maintains total service provided by the first and second resources to the first and second consumers in proportion to the respective weights of the first and second consumers without requiring the first and second schedulers to communicate with each other.

Method and apparatus of invoking services in a telecommunications terminal

Abstract: The invention is concerned with a method in a telecommunications terminal, e.g. a mobile phone, comprising an identification module with several subscriber numbers, of invoking desired services provided by different service providers. In the method a category of an incoming or outgoing call can be determined. A desired service is selected, in accordance with the category determined, among the services provided by a service provider associated with the mobile phone through service access numbers stored in the module. There is called to a service access number of the service provider providing a desired service in accordance with a certain call handling function by means of which the desired service can be invoked and charged in different ways, whereafter the service provided by the service provider is invoked. The invention is also concerned with a telecommunications terminal and the use of the terminal in different roles, such as a private person, an employee and as a member in different organizations.
