摘要： A method for allocating network addresses comprises providing an address pool comprising a plurality of network addresses and then dividing the address pool into a plurality of address sub-pool that comprise a unique subset of the network addresses of the address pool. Each of the sub-pools is available for use by any one of a plurality of routing devices of a network access server. The method then comprises receiving a request to assign a first network address to a first user, allocating a first address sub-pool of the plurality of address sub-pools to a first routing device of the plurality of routing devices and transmitting a first message to the other routing devices to indicate that the first address sub-pool has been allocated. The method additionally comprises assigning the first network address to the first user from the first address sub-pool and advertising an aggregate route for the first address sub-pool over a network.

摘要： A system and method is provided for transferring packet-switched data across a network. A network interface may be connected to a primary switch and a secondary switch, both of which may be connected to a network. The network interface may also convert between circuit-switched data and packet-switched data. Further, packet-switched data may be transferred between the network interface and the network across the primary switch if the primary switch is operable, and across the secondary switch if the primary switch is inoperable. The system and method may also include a selection switch, route server and controller. Additionally, the system and method may include a primary router and a secondary router. Packet-switched data may be transferred across the primary router if the primary router is operable, and across the secondary router if the primary router is inoperable.

摘要翻译： 提供了一种用于通过网络传送分组交换数据的系统和方法。 网络接口可以连接到主交换机和辅助交换机，二者可以连接到网络。 网络接口也可以在电路交换数据和分组交换数据之间进行转换。 此外，如果主交换机是可操作的，则分组交换数据可以在主交换机之间的网络接口和网络之间传送，并且如果主交换机不可操作，则可跨越次交换机。 系统和方法还可以包括选择开关，路由服务器和控制器。 此外，该系统和方法可以包括主路由器和辅助路由器。 如果主路由器可操作，则分组交换数据可以跨主主路由器传输，如果主路由器不可操作，则可跨越次路由器。
