An architecture for automated replacement of QoS policies
نویسندگان
چکیده
This paper introduces the notion of PoP (Policy of Policies) used to define standard policy replacement strategies in a policy-based network. We also propose an architecture to support PoP within PDPs (Policy Decision Points originally defined by the IETF). The notion of PoP, and the proposed architecture allow the automation of the policy replacement task currently manually executed by the network administrator based on the network business plan.

An automatic test case generator for evaluating implementation of access control policies
One of the main requirements for providing software security is the enforcement of access control policies which aim to protect resources of the system against unauthorized accesses. Any error in the implementation of such policies may lead to undesirable outcomes. For testing the implementation of access control policies, it is preferred to use automated methods which are faster and more relia...
متن کاملPolicy Specification and Architecture for Quality of Service Management
An application’s Quality of Service (QoS) requirements refers to non-functional, run-time requirements. These requirements are usually soft in that the application is functionally correct even if the QoS requirement is not satisfied at run-time. QoS requirements are dynamic in that for a specific application, they change. The ability to satisfy an application’s QoS requirement depends on the av...

متن کاملSHReQ: A Framework for Coordinating Application Level QoS
We present SHReQ, a formal framework for specifying systems that handles abstract high-level QoS aspects which are becoming more and more important for service oriented computing. SHReQ combines Synchronised Hyperedge Replacement (SHR) with constraint-semirings. SHR is a (hyper)graph rewriting mechanism for modelling mobility and reconfiguration of systems. The novelty of the approach relies on...
متن کاملRetrieval–travel-time model for free-fall-flow-rack automated storage and retrieval system
Automated storage and retrieval systems (AS/RSs) are material handling systems that are frequently used in manufacturing and distribution centers. The modelling of the retrieval–travel time of an AS/RS (expected product delivery time) is practically important, because it allows us to evaluate and improve the system throughput. The free-fall-flow-rack AS/RS has emerged as a new technology for dr...
