Manual deployment and management are becoming overwhelming with the increasing complexity of networks. Automated deployment and management are imperative and can respond to user requirements promptly. This research provides resource allocation models that cooperated with the NFV orchestration engine and improve the network performance.The research focuses on fault tolerances for unknown failures. Two models for static and dynamic scenarios are proposed. The allocation provided by the proposed models ensures the processing ability satisfies the requirements even though there are k failed nodes in the network. The numerical results show that the proposed models reduce the E2E latency between the VNFs and increase the number of accepted requirements ensuring the resiliency of the functions.

随着网络复杂性的增加，手动部署和管理变得越来越难以承受。自动化部署和管理势在必行，能够及时响应用户需求。本研究提供了与NFV编排引擎配合的资源分配模型，提高网络性能。研究重点是未知故障的容错能力。提出了静态和动态场景的两种模型。即使网络中有 k 个故障节点，所提出的模型提供的分配也确保了处理能力满足要求。数值结果表明，所提出的模型减少了 VNF 之间的 E2E 延迟，并增加了可接受的需求数量，确保了功能的弹性。
