Abstract

The COPS-PR protocol has been defined by the IETF to provide policy provisioning in networks managed through the policy-based network management approach. Although some network players already ship their devices with proper COPS-PR support, there is a trend in the industry and in the IETF of discontinuing COPS-PR as a policy protocol. Meanwhile, two other protocols, namely NETCONF and SOAP, have been seriously considered in the network management field. This paper proposes and evaluates both NETCONF and SOAP as substitutes for COPS-PR, presenting how these protocols can be used for policy provisioning. The performance evaluation of NETCONF and SOAP against COPS-PR addresses two main aspects: network usage as a result of protocol overhead, and protocol delay as a result of protocol message processing. This study shows that both NETCONF and SOAP are interesting and feasible replacements for COPS-PR, but require appropriate modeling when deployed in networks

代替cop - pr:对NETCONF和SOAP进行策略配置的评估

cop - pr协议由IETF定义，用于在通过基于策略的网络管理方法管理的网络中提供策略供应。尽管一些网络厂商已经提供了适当的COPS-PR支持，但在业界和IETF中有一种趋势，即不再将COPS-PR作为策略协议。同时，另外两个协议NETCONF和SOAP在网络管理领域得到了认真的考虑。本文提出并评估了NETCONF和SOAP作为cop - pr的替代品，并介绍了如何将这些协议用于策略配置。NETCONF和SOAP对cop - pr的性能评估涉及两个主要方面:由于协议开销导致的网络使用，以及由于协议消息处理导致的协议延迟。本研究表明，NETCONF和SOAP都是cop - pr的有趣且可行的替代品，但在网络中部署时需要适当的建模
