Today, service provisioning suggests reserving network and equipment resources to satisfy a user request, but in the Next Generation Network and Next Generation Service (NGN/NGS) context the user's needs are becoming increasingly complex and need to take account the user mobility and preferences changes in the behavior of the service. Thus, it is necessary to reserve the “Service Resource” as well as the network and equipment resources. In this paper we propose a mechanism for service resource provisioning similar to that of routing networks. This service resource is shared between several users and is allocated dynamically according to its current QoS. The dynamic management of this service resource allows us to anticipate degradations and thus to always satisfy the user Service Level Agreement.
