here is a flurry of activity in the networking community developing advanced services networks. Although the focus of these efforts varies widely from per-flow service definitions like integrated services (IntServ) [1,2] to service frameworks like Xbind [3], they share the overall goal of evolving the Internet service model from what is essentially a basic bitway pipe to a sophisticated infrastructure capable of supporting novel advanced services.In this article we consider a network environment that comprises not only communication services, but storage and computation resources as well. By packaging storage/computation resources together with communication services, value-added service providers will be able to support sophisticated services such as intelligent caching, video/audio transcoding and mixing, virtual private networking, virtual reality games, and data mining. In such a service-oriented network, value-added services can be composed in a hierarchical fashion: applications invoke high-level service providers, which may in turn invoke services from lower-level service providers. Providers in the top of the hierarchy will typically integrate and add value to lower-level services, while the lowest-level services will supply basic communication and computational support. Since services can be composed hierarchically, both applications and service providers will be able to combine their own resources with resources or services delivered by other service providers to create a high-quality service for their clients. The design of such a service-oriented network poses challenges in several areas, such as resource discovery, resource management, service composition, billing, and security. In this article we focus on the resource management architecture and algorithms for such a network.Service-oriented networks have several important differences from traditional networks that make existing network resource management inadequate. First, while traditional communication-oriented network services are provided by switches and links, value-added services will have to manage a broader set of resources that includes computation, storage, and services from other providers. Moreover, interdependencies between differ-0890-8044/01/$10.00 AbstractThe Internet is rapidly changing from a set of wires and switches that carry packets into a sophisticated infrastructure that delivers a set of complex value-added services to end users. Services can range from bit transport all the way up to distributed value-added services like video teleconferencing, virtual private networking, data mining, and distributed interactive simulations. Before such services can be supported in a general and dynamic manner, we have to develop appropriate resource management mechanisms. These resource management mechanisms must make it possible to identify and allocate resources that meet service or application requirements, support both isolation and controlled dynamic sharing of resources across services and applications sharing physical resources, a...

Cross layer optimizations are increasingly being used in a variety of applications to improve application performance. However most of these implementations are ad hoc and performed on a per application basis. In this paper we propose a declarative framework for managing application and network adaptations. The declarative paradigm provides a much needed clean line of separation between the high level goals and the low level implementations. Our framework exposes the tunable features of both the application and the network across layers of the network stack which can then be jointly optimized. We allow operators to control the adaptation process through operator specified policies. This enables operators to retain control over their networks while the application and the network adapt in response to changing conditions. To support evolution, we pursue an ontological approach and use semantic web languages such as OWL and RDF in our framework for the policy and declarative specifications, thereby also leveraging the inherent reasoning and conflict resolution features of these languages. We then describe our framework developed on top of NS2 to demonstrate the utility of our approach in the easy implementation of cross layer optimizations through sample application scenarios.

Self-organized mobile networks present a challenging environment for the execution of software applications, due to their dynamic topologies and consistently changing resource conditions. In view of the above, a desirable property for software applications to be run over these networks is their ability to dynamically adapt to changing execution environments. The Contract-based Adaptive Software Architecture (CASA) provides a framework for the development of adaptive applications that are able to adapt their functionality and/or performance dynamically in response to runtime changes in their execution environments. The approach of the CASA framework is to decouple application code from any assumptions about resource availability, while enabling the application to execute under varying resource conditions. The CASA framework relies on specifying adaptation behavior of applications in application contracts, which enables the dynamic adaptation to be carried out in an application-transparent manner.
