“…In prior work from our group [9], we proposed the CoCoNET architecture for content based networking in which packets are semantically tagged using an operator specified ontology. The meta data could be used to specify a variety of properties such as type of data, security credentials etc.…”

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.

“…Using semantic tags and associated rules, the reasoner is smart enough to differentiate between a network surveillance video (admin traffic) and a regular movie clip which traditional techniques such as packet header inspection cannot because both will appear as standard MPEG flows. In addition, the reasoner can also specify intraflow packet prioritization driven by policies [8]. V. RELATED WORK Policy based networks and approaches have been the focus of extensive research in recent years.…”

Abstract-Policy based networks provide high levels of flexibility by allowing definition of packet handling rules within a network, resource allocation strategies, network management, or access control. Commonly used policy specification mechanisms are, however, limited in their expressibility and rely mostly on packet headers that convey limited information about the semantics of the content. We propose a new model for policy based networking that utilizes the W3C Web Ontology Language tags carried in data packets that can provide detailed semantic information about the packet or stream. Using this model, a policy decision point can reason over these tags and infer the correct set of operations to invoke. Policies are expressed in the W3C Semantic Web Rule Language using a common ontology and take into consideration the content of the streams, relevant contextual information and external domain constraints. Using this framework, fine grained, highly specialized services can be offered within the network that are context-aware, easy to manage, deploy and verify for consistency.

This paper proposes a Software Defined Networking-(SDN-) based active content networking architecture for future media environments. The proposed architecture aims to provide customized delivery of various types of media content in order to satisfy users' demand and service requirements. To this end, we have developed an active content processing model which provides innetwork content processing through service objects that are integral parts of active content. The main benefits provided by the proposed model are high flexibility and creativity to meet the evolving future media environments.
