【摘要】 本文提出了一种使用QoS保护来增强当前QoS路由的方法。在MPLS网络内,预先确定需保护的网段。LSP请求除建立工作路径外,还创建一条备份路径(本地的、反转的或全局的)。本方法考虑不同的QoS参数,如网络负载均衡、资源优化和LSP请求拒绝的最小化。QoS保护被定义为QoS参数的一个功能,同时,引入一种在当前多种QoS路由算法中增加QoS保护的结构,并给出了选择最适合的保护方法的备份决策模式。更多还原

【Abstract】 In this paper,a method for enhancing current QoS routing by means of QoS protection is presented.In an MPLS network,the segments to be protected are predefined.LSP request involves,apart from establishing a working path,creating a specific type of backup path(local,reverse or global).Different QoS parameters,such as network load balancing,resource optimization and minimization of LSP request rejection should be considered.QoS protection is defined as a function of QoS parameters.A framework to add QoS protection to many of the current QoS routing algorithms is introduced.A Backup Decision Module to select the most suitable protection method is formulated.更多还原
