    摘要： A multi-service network switch capable of providing multiple network services from a single platform. The switch incorporates a distributed packet forwarding architecture where each of the various cards is capable of making independent forwarding decisions. The switch further allows for dynamic resource management for dynamically assigning modem and ISDN resources to an incoming call. The switch may also include fault management features to guard against single points of failure within the switch. The switch further allows the partitioning of the switch into multiple virtual routers where each virtual router has its own set of resources and a routing table. Each virtual router is further partitioned into virtual private networks for further controlling access to the network. The switch supports policy based routing where specific routing paths are selected based on a domain name, a telephone number, and the like. The switch also provides tiered access of the Internet by defining quality of access levels to each incoming connection request. The switch may further support an IP routing protocol and architecture in which the layer two protocols are independent of the physical interface they run on. Furthermore, the switch includes a generic forwarding interface software for hiding the details of transmitting and receiving packets over different interface types.

    摘要翻译： 一种能够从单一平台提供多种网络服务的多业务网络交换机。 交换机集成了分布式分组转发架构，其中每个各种卡能够进行独立的转发决策。 该交换机进一步允许动态资源管理，以动态地将调制解调器和ISDN资源分配给来电。 交换机还可以包括故障管理特征以防止交换机内的单点故障。 交换机还允许将交换机划分成多个虚拟路由器，其中每个虚拟路由器具有其自己的一组资源和路由表。 每个虚拟路由器被进一步划分成虚拟专用网络，以进一步控制对网络的访问。 交换机支持基于策略的路由，其中​​基于域名，电话号码等选择特定路由路径。 交换机还通过定义每个传入连接请求的访问级别的质量来提供互联网的分层访问。 交换机可以进一步支持IP路由协议和架构，其中第二层协议独立于其运行的物理接口。 此外，该交换机包括用于隐藏通过不同接口类型发送和接收分组的细节的通用转发接口软件。
