__c__. INext-eneration networks must be capable of supporting a multitude of service and quickly adapted over a common heterogeneous physical infrastructure, according to varying and sometimes conflictin customer requirements. In this context, network management must become more fyexible in order to cope with these emerging conditions. More specifically, new management architectures must offer service providers the freedom to mana e their services according to their own policies and seamlessly extend management?unctionality os the only way to react to the introduction of new services. Based on a new business model that describes such an environment, we propose o policy-based management architecture that is extensible and operates i n an active and programmable network. This management architecture is part of a new network architecture that was developed in the FAIN European Union research aid development IST project. provi B ers that exploit an environment in which services are dynamically deployed n the world of networking we are experiencing a significant paradigm shift resulting in new technologies and architectures. The motivation behind this shift is the still elusive goal of rapid and autonomous service creation, deployment, activation, and management resulting from new customer and application requirements. Research activity in this area has clearly focused on the synergy of three concepts: network virtualization, open interfaces and platforms, and increasing degrees of intelligence inside the network.Management, as a key component of a network architecture; must also be considered and designed around the same concepts. To this end, the management architecture must support the coexistence of different management strategies, facilitating customization and interoperation with different vendors' equipment. Management must also be dynamically extensible to support the deployment and operation of new services.In this article we describe the management aspects of a new network architecture designed and implemented as part of the Future Active IP Networks (FAIN) European Union R&D IST project [l]. The main objective of the FAIN project is to develop an active network (AN) architecture oriented toward dynamic service deployment in heterogeneous networks. This architecture.encompasses the design and implementation of active nodes that support different types of execution environment, policy-based driven network management, and a platform-independent approach to service specification and deployment. The architecture is deployed and evaluated in a pan-European testbed. ,The FAIN management architecture encapsulates the three aforemcntioned concepts and is built in accordance with the Internet Engineering Task Force's (IETF's) policy-based management framework [Z]. used in an active network environment. As a consequence, it inherits the features o f this enabling technology, which are then applied to this new prohlem space.Wc briefly introduce the FAIN business model on which the management architecture is based. We g...
Abstract. This paper describes a dynamic, scalable and extensible policy-based network management (PBNM) system that is fully integrated with a service provisioning architectures for active networks. The key result is network customisation according to the needs of the different service providers and its end users. Our component-based service provisioning architecture enables us to render service-and user-specific requirements, across single/multiple administrative domains, at deployment time and to dynamically map service components onto the network using the corresponding management policies. The architecture presented in this paper describes the approach undertaken by the IST-FAIN research project as well as the main issues that we encounter in developing and integrating the PBNM with the service provisioning mechanism.
Abstract-This paper presents a SNMP-based Monitoring Agents forMulti-Constrain Resource Scheduling in Grids (SBLOMARS) as an effective solution for resource usage monitoring in virtual network environments. SBLOMARS is different to current large-scale distributed monitoring systems in three essential aspects: Firstly, it reaches a high level of generality by the integration of the SNMP protocol and thus, facilitates to handle heterogeneous operating platforms. Secondly, it is able to self-configure the polling periods of the resources to be monitored depending of network context and finally, it makes use of dynamic software structures to interface with third parties, allowing to be deployed in a wide range of devices, from simple mobile access devices to robust multiprocessor systems or clusters with even multiple hard disks and storage partitions. SBLOMARS has been deployed in EmanicsLab, a virtual laboratory constituted by fourteen nodes distributed in seven European Universities. Although the research is not yet concluded, available results confirm its suitability to deal with the challenges of monitoring virtual networks.
This paper describes a dynamic, scalable and flexible Policy-based Management Architecture (PbMA), which is characterized by a reliable and autonomous deployment, activation and management of Grid Services. This architecture follows the implied conditions by the Open Grid Services Architecture (OGSA) standard. Although applicable to any user profiles, our system is essentially intended for non-massive resource owners accessing large amounts of computing, software, memory and storage resources. Unlike similar architectures, it is able to manage service requirements demanded by users, providers and services themselves. This architecture is also able to manage computational resources in order to fulfill Quality of Service (QoS) requirements, based on a balanced scheduling of resources exploitation. Our approach is scalable and flexible by extending itself the management components and policies interpreters needed to control multiple infrastructures regardless network technology, operative platform or administrative domain. The management architecture shows its reliability through a Grid Service deployment example.
Abstract. Communication technologies are evolving along with GridComputing. The trend of Open Grid Services Architecture (OGSA) is that "everything" is represented as a service, which will be provided to users without any kind of distinctions related to network technology, operative platform, administrative domain, etc. As a result of this trend, there has been a significant management requirement increase in order to cope with the yet elusive rapid and autonomous service creation, deployment, activation and management. This paper describes a proposal to cope with the above mentioned management requirements. Our policybased management approach enables the establishment, configuration and administration of services on a Grid network that uses the Globus Architecture for Reservation and Allocation (GARA) as an interface for reservation and provisioning of grid resources.
