摘要： A system and method for updating forwarding tables in a blade packet manager is provided. The blade packet manager may include master and slave blades. A master management module on the master blade monitors the slave blades. Network address entry forwarding tables are maintained on the slave blades. A periodic sweep of slave blades for activity information is performed and reports are forwarded to the master blade. The master blade propagates the reported information from the master blade to each of the slave blades to update forwarding tables on each of the slave blades.
摘要翻译：提供了一种用于更新刀片包管理器中的转发表的系统和方法。刀片包管理器可以包括主刀片和从刀片。主刀片上的主管理模块监控从刀片。网络地址条目转发表保留在从属刀片上。执行用于活动信息的从属刀片的周期性扫描，并将报告转发到主刀片。主刀片将报告的信息从主刀片传播到每个从刀片，以更新每个从刀片上的转发表。

摘要： One embodiment disclosed relates to an apparatus for routing packets towards destination addresses. The apparatus includes at least a routing table and a route fragment cache. Each route in the routing table includes a network address, a mask, and a corresponding forwarding information. Each route fragment in the route fragment cache includes a section of a route from the routing table. The route fragments are such that no route fragment in the route fragment cache intersects any route in the routing table that is more specific than the route from which that fragment was generated.
摘要翻译：公开的一个实施例涉及用于将分组路由到目的地地址的装置。该装置至少包括路由表和路由片段高速缓存。路由表中的每个路由都包括网络地址，掩码和相应的转发信息。路由片段高速缓存中的每条路由片段都包含路由表中路由的一部分。路由片段使得路由片段缓存中的路由片段与路由表中的任何路由相交，该路由片段比生成该片段的路由更具体。

摘要： An apparatus and method of replacing a router in a Layer 3 network, includes configuring a new router to accept a data packet having, as a destination address field, a first media access control address of a replaced router. The method further comprises setting the destination address field of the data packet to the MAC address of the new router, and forwarding the data packet. A router performing the above method comprises configuration logic to configure the router to accept a data packet having, as a destination address, a media access control address of a replaced L3 device; and keep-alive logic adapted to periodically transmit a keep-alive packet to an allocated destination address. The router further comprises packet processing logic that accepts the received data packet, sets the destination address of the data packet to the MAC address associated with the router, and forwards the packet to a destination host.
摘要翻译：一种替换第3层网络中的路由器的装置和方法，包括配置新路由器以接受具有作为目的地址字段的替换路由器的第一媒体访问控制地址的数据分组。该方法还包括将数据包的目的地址字段设置为新路由器的MAC地址，并转发数据包。执行上述方法的路由器包括配置逻辑，用于配置路由器接受具有作为目的地地址的替换的L3设备的媒体访问控制地址的数据分组; 以及适用于周期性地向所分配的目的地地址发送保持活动分组的保持活动逻辑。路由器还包括接收接收到的数据分组的分组处理逻辑，将数据分组的目的地址设置为与路由器相关联的MAC地址，并将分组转发到目的主机。
