摘要： An adjunct network device includes several ports, an uplink interface, and an adjunct forwarding engine coupled to the ports and the uplink interface. A first port is configured to receive a packet, which includes a destination address. The adjunct forwarding engine is configured to send the packet to the uplink interface if the destination address is not associated with any of the ports. The packet is sent to one of the ports if the destination address is associated with the one of the ports.

摘要： A blade router for increased interface scalability is provided. The blade router may address interface scalability by having each of the linecards manage its interfaces locally and may use the concept of virtual and local interfaces for intelligent forwarding. The blade router may appear as a single router from the customer perspective during configuration. For some embodiments, two virtual interfaces may be used, one for regular interface traffic and another for Network Address Translation (NAT)-enabled interface traffic.

摘要： A method may involve: receiving a packet (e.g., via a port or uplink interface in a satellite switch) and conveying the packet between one or more ports and one of several uplink interfaces. The one or more ports and the uplink interface are associated with each other. The association can be independent of VLAN (Virtual Local Area Network). As an example, such a method can involve: receiving a first packet via a first port; conveying the first packet to a distribution-layer via a first uplink interface; receiving a second packet via a second port; and conveying the second packet to the distribution-layer via a second uplink interface, where the first uplink interface is associated with the first port and the second uplink interface is associated with the second port. In some embodiments, ports and uplink interfaces are associated by being assigned to the same virtual linecard.
摘要翻译：方法可以包括：接收分组（例如，经由卫星交换机中的端口或上行链路接口）并且在一个或多个端口与多个上行链路接口中的一个之间传送分组。一个或多个端口和上行链路接口彼此相关联。该关联可以独立于VLAN（虚拟局域网）。作为示例，这种方法可以包括：经由第一端口接收第一分组; 经由第一上行链路接口将所述第一分组传送到分发层; 经由第二端口接收第二分组; 以及经由第二上行链路接口将所述第二分组传送到所述分发层，其中所述第一上行链路接口与所述第一端口相关联，并且所述第二上行链路接口与所述第二端口相关联。在一些实施例中，端口和上行链路接口通过分配给相同的虚拟线卡相关联。

摘要： A an example method includes building a dictionary between an exporter and a collector by encoding a first data record of a flow according to a dictionary template and exporting the first data record to the collector via a network communication. The method can also include compressing a second data record of the flow using the dictionary, where the compressing comprises encoding the second data record according to an encoding template; and exporting the second data record to the collector to be decompressed using the dictionary.
