A policy-based approach to E2E service negotiation via third party agent

In this paper, we propose a policy-based model to achieve end-to-end (E2E) service negotiation among multiple domains that constitute E2E path. The model relies on a centralized approach, realized via the third party (3P) agent, which acts as a proxy server for local (per-domain) management entities. We demonstrate the proposed model on the implementation of policies for allocation of performance impairment budgets among domains, and present the appropriate software design.
