“…The meta data could be used to specify a variety of properties such as type of data, security credentials etc. A reasoner at each node could then reason over the meta data and perform appropriate functions as specified by policies [10]. In [11], we extend the framework to manage BGP export policies.…”

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.

“…Various approaches from the former class use network management policies expressed in semantic Web languages (e.g., the Web Ontology Language -OWL, the Web Ontology Language for Web services -OWL-S, and the Semantic Web Rule Language -SWRL) for the self-provisioning of network services such as: firewalls [14], routing protocols [15], and data streams [16], or for top-down policy refinement [17], [18]. The drawbacks of these solutions are the following: (i) OWL and OWL-S ontologies are more adequate for specifying semantic Web content rather than configuration information models for service provisioning; (ii) Web service-based network management approaches assume that devices are managed via Web services (which is not always the case) [18]; and (iii) top-down refinement of network management policies is still an open issue [18], especially at the device configuration level.…”

Due to the unprecedented development of networks, manual network service provisioning is becoming increasingly risky, error-prone, expensive, and time-consuming. To solve this problem,rule-based methods can provide adequate leverage for automating various network management tasks. This paper presents a rule-based solution for automated network service provisioning. The proposed approach captures configuration data interdependencies using high-level, service-specific, user-configurable rules. We focus on the service validation task, which is illustrated by means of a case study.

Based on numerical results, we analyse the influence of the network-level complexity factors and rule descriptive features on the rule efficiency. This analysis shows the operators how to increase rule efficiency while keeping the rules simple and the rule set compact. We present a technique that allows operators to increase the error coverage, and we show that high error coverage scales well when the complexity of networks and services increases.
We reassess the correlation function between specific rule efficiency and rule complexity metrics found in previous work, and show that this correlation function holds for various sizes, types, and complexities of networks and services.

Abstract-Security is emerging as an important requirement for a number of distributed applications such as online banking, social networking etc. due to the private nature of the data being involved. Further more, the wide spread use of portable devices such as laptops, PDAs etc. allows users to make meaningful ad hoc collaborations. Traditional security solutions are not feasible for these scenarioes due to the varying nature of the collaborations in terms of entities involved and their roles, available resources etc. Under these circumstances, we need generic solutions that take into account the semantics of the collaborations in determining the set of allowable operations. In this paper, we propose an extensible framework that uses semantics driven policies for enforcing security. Our policies are rooted in semantic web languages which makes amenable to interoperability, and also enables high level reasoning for conflict resolution and policy adaptation. We describe our policy based network that uses packet content semantics to best handle different streams, and show how our framework can be used to secure enterprise networks and the BGP routing process.
