[摘要] 虚拟宽带远程接入服务器(vBRAS)已经成为电信运营商在IP城域网(MAN)引入网络功能虚拟化(NFV)的一个切入点,主要应用在一些小流量、常在线业务场景以及需要集中运营的业务场景。在vBRAS的性能评估方面,可以通过资源占用率等基本指标和稳定系数、均衡系数和无关系数等扩展指标来综合衡量。

[Abstract] Virtual broadband remote access server (vBRAS) has become one of the network function virtualization (NFV) scenarios in IP metropolitan area network (MAN). And vBRAS is mainly used in two scenarios: one is to support the small flow and always online business, another is for the business which needs to be concentrated on operating. There are some basic indicators such as resource utilization and extended indicators including stability coefficient, equilibrium coefficient and unrelated coefficient to evaluate the performance of vBRAS.
