摘要

针对用户对网络服务的差异化可靠性需求，提出一种带有区分保护的虚拟化光无线融合网络可靠传输机制。以用户需求的保护质量及所能够支付的费用作为条件，通过恢复概率进行多等级保护质量的量化，灵活地分配备份保护资源；利用等级服务区分算法筛选满足业务保护质量等级的保护路径，降低业务阻塞以及不受保护的业务数量，提高业务保护质量。结果表明所提机制在平均收益开销比和底层网络资源开销等指标上具有较高优势，在满足用户可靠性需求的同时，能够为用户提供更灵活的虚拟网络数据传输。

Abstract

In view of the different reliability requirements of network service

a reliable transmission mechanism with differentiated protection was proposed in virtualized fiber-wireless access network.The quality of protection required by users and the fees that can be paid were used as a prerequisite.The backup protection resources were flexibly allocated by quantifying the multi-level protection quality with the probability of recovery.Then

for reducing traffic congestion and the unprotected services

the level service differentiation algorithm was used to choose protection link which was satisfied with the level of protection quality.The results show the proposed mechanism has more advantages in terms of long-term benefit-to-cost ratio and underlying network resource overhead

and provides users with a more flexible virtual network transmission while satisfying users’ reliability requirements.
