“…The overall impairment budget is an upper bound of the allowed E2E performance impairment for metrics such as delay, jitter and packet loss rate. The first task implements the policy for dividing this overall budget among domains on the path [21,22]. The second task information.…”

This paper presents a centralized approach for establishing end-to-end communication services via management agents. The main proposal is the modular architecture of the third-party based Service Establishment Agent (SEA). The SEA manages inter-provider service negotiation process with per-domain management agents through an appropriate signaling agent. It also receives and interprets end-toend service requests, selects inter-domain paths, performs mapping of service classes among domains on the path, and evaluates conformance of the offered service level with the required one. It allows implementation of different algorithms for the aforementioned functions as well as their selection and combination according to the predefined management policies. Simulation results show that the proposed model significantly outperforms the distributed model in terms of service negotiation times. In the prototype development process, a policy-based solution for mapping of service classes was implemented. The performance evaluation shows that processing requirements for handling multiple service requests are modest, while benefit of the SEA approach is the lack of need to build long-term consensus among providers about technical choices for achieving network interconnection. The SEA architecture is completely independent of the quality of service mechanisms available in particular domains.

“…In order to evaluate 3PIP class selection, we investigate E2E service performance and cost, which is quantified using fictive monetary units (MU). Mappings are then compared with the existing 3P mapping technique P-CMS that is proposed and analyzed in [10]. The compared algorithms have been implemented in MATLAB.…”

In this paper, we propose a novel algorithm for mapping of service classes among multiple Internet providers on an end-to-end (E2E) path. The third-party (3P) approach is assumed for E2E service negotiation, whereas the foundation for class mapping is laid on the integer programming mathematical model. The algorithm selects service classes in domains on the path so that requirements for E2E quality of service (QoS) are fulfilled. This selection is based on multiple constraints, referring to performance fulfillment and at the same time aiming to achieve minimal E2E interconnection cost through definition of a single objective function. Performance evaluation has clearly indicated benefits of the proposed algorithm in terms of QoS achievement and decreasing costs, as well as its suitability for services that require stringent QoS guarantees.

“…Also, the number of defined classes and metric specifications per class depend on the provider's policy, so various levels of QoS granularity may be expected on the E2E path. Similar QoS specification is used in [9], [10] and [20]. Class mapping is investigated on the two paths consisting of five and three domains respectively, i.e., A1-R1-C-R2-A2 and A3-R3-A4 according to Table 2.…”
