动态电路网络（DCN）是一种生产提前带宽预留服务。目前，大多数 DCN 运营商提供单一服务类别 (CoS)，例如，要么保证带宽，要么不保证服务质量。尽管单一 CoS 配置是可行且方便的，但多类服务（多 CoS）配置提供了非常优越的实践，包括基于质量的商业服务收费和高效的资源管理。本文提出了一种在 DCN 中提供带宽和延迟保证的多 CoS 架构，更具体地说，是在多协议标签交换 (MPLS) 网络上部署按需安全电路和提前预订系统 (OSCARS)。本文的主要贡献是保证带宽和延迟类别，其中系统可以计算满足给定带宽和延迟约束的路径。我们的系统在实际路由器上进行了测试。
A dynamic circuit network (DCN) is a production advance bandwidth reservation service. The majority of DCN operators currently provide a single class of service (CoS), e.g., either a guarantee of bandwidth or no guarantee of quality of service. Although single CoS provisioning is viable and expedient, multiple classes of service (multi-CoS) provisioning offers greatly superior practice, including quality-based charging for a commercial service and efficient resource management. This paper proposes a multi-CoS architecture with bandwidth and delay guarantees in a DCN, more specifically, the deployment of On-Demand Secure Circuits and Advance Reservation System (OSCARS) over multiprotocol label switching (MPLS) networks. The main contribution of this paper is a guaranteed bandwidth-and-delay class where the system can compute the path which can satisfy the given bandwidth and delay constraints. Our system was tested on practical routers.
