摘要:

网络虚拟化技术为目前的网络架构提供了一种有效的扩展手段。近年来,底层网络基础设施失效事件频发,因此如何提高虚拟网络的可靠性成为目前该领域一个研究热点。对在保证虚拟网络可靠性的同时如何最小化底层网络映射开销问题进行研究,设计了一个新的启发式算法对其进行求解。实验表明,相比其他算法,所提算法网络带宽资源开销更低。

关键词: 网络虚拟化, 虚拟网络映射, 启发式

Abstract:

Network virtualization has been proposed as a promising way for expanding the network architecture.However,how to provide reliable VN against substrate infrastructure failures has become an increasingly important issue.Meanwhile the substrate network resource cost should be minimized under VN reliability guarantees to maximize the revenue for the in-frastructure providers (InP).A novel heuristic VN mapping algorithm was presented.Simulation results show that proposed algorithm can gain near optimal network bandwidth usage compared to the previous algorithms.

Key words: network virtualization, virtual network mapping, heuristic
