    Abstract: PURPOSE: A method for construction of a forwarding table in an MPLS(Multi Protocol Label Switching) L3VPN is provided to perform stable packet forwarding using a plurality of forwarding tables without memory expansion. CONSTITUTION: In a forwarding process(173), forwarding information of routing software is read from a forwarding information queue(171). If the forwarding information queue is the forwarding information about VPN(Virtual Private Network), the forwarding information about VPN is stored in the next hop table(175). If the route information is newly registered information, the next hop index is allocated through the next hop index administrator(172). In case forwarding route information(174) is updated, the next hop Index field is updated in a forwarding table(140).

    Abstract translation: 目的:提供一种在MPLS(Multi Protocol Label Switching,多协议标签交换)L3VPN中构建转发表的方法,使用多个转发表进行稳定的数据包转发,无需扩展存储器。 规定:在转发过程(173)中,从转发信息队列(171)读取路由软件的转发信息。 如果转发信息队列是关于VPN(虚拟专用网络)的转发信息,则转发关于VPN的信息存储在下一跳表(175)中。 如果路由信息是新注册的信息,则通过下一跳索引管理员(172)分配下一跳索引。 在更新转发路由信息(174)的情况下,在转发表(140)中更新下一跳索引字段。
