Component-Based Deployment and Management of Services in Active Networks

Abstract

This paper 1 describes a holistic approach towards the deployment and runtime management of services on active network nodes taken by the FAIN project. Both the underlying service model and the architectures supporting deployment and management are component oriented. The separation of service meta-information and implementation code allows for a very flexible way of service deployment management as it facilitates selective code distribution, finegrained installation and instantiation. Active services are composed from a set of service components that can be selected on demand at deployment time and installed in any combination of the data, control, and management planes which enables realisation of arbitrary active services.

A Policy-Based Management Architecture for Flexible Service Deployment in Active Networks

“…At the node level, the ASP identifies necessary service components by resolving node-level component dependencies and coordinates component installation, activation and pre-configuration in the execution environments located on the node. Active services that can be deployed using the ASP system have to conform to the FAIN service model presented in [5]. The work described in this paper extends the one presented in [6] by discussing the network-level deployment process.…”

“…The FAIN service model used is component-based [5]. It allows structuring services using self-contained software units of deployment, management and computation, called service components.…”

“…These requirements include the execution environment and node resources needed for execution and they are specified with the help of node level service descriptor as described in [5].…”

“…The FAIN programmable node is described in [3]. The FAIN network management architecture consists of the Policy-Based Network Management (PBNM) [4] and the Active Service Provisioning (ASP) [5] systems, which provide higher-level management and service deployment mechanisms built on top of an active network infrastructure. In this paper we describe the final implementation of both the PBNM and ASP systems as well as the intercommunication mechanism developed in order to offer a flexible service deployment on active networks.…”

“…We further introduce new PBNM components at the network-level that were developed to address the management aspects of end-to-end service creation and deployment, i.e., Resource Manager (RM), Service Manager (SM) and the Inter Domain Manager (IDM). For these purposes, the network-level ASP was developed, which enhances our node-level ASP [5] work. We also consider the case when the network management system is requested to deploy a service in a target node outside of its domain.…”
