摘要： A network device coordinates with other devices in a network to create a distributed filtering system. The device detects an attack in the network, such as a distributed denial of service attack, and forwards attack information to the other devices. The devices may categorize data into one or more groups and rate limit the amount of data being forwarded based on rate limits for the particular categories. The rate limits may also be updated based on the network conditions. The rate limits may further be used to guarantee bandwidth for certain categories of data.

摘要： A forwarding node decapsulates and encapsulates data. The decapsulation may be performed using pattern matching techniques and the encapsulation may be performed using pattern insertion techniques. The decapsulation and encapsulation are preferably performed by hardware devices such as application specific integrated circuits (ASICs) to enhance the speed of such operations. The decapsulation and encapsulation may be independent of each other and performed on a per virtual circuit basis.

摘要： A switch/router contains intelligence for more quickly determining a next hop for an network layer packet. A network forwarding lookup table or array structure is configured so as to minimize the number of memory accesses required. This results in a decrease in time due to memory access and a decrease in computational overhead due to the memory accesses. In one embodiment, a first forwarding lookup is indexed by the first 16 bits of a destination address. A second forwarding lookup is indexed by the subsequent 8 bits of the destination address, and a final third forwarding lookup is indexed by the last 8 bits of the destination address. Each entry within a forwarding lookup contains either direction as to how properly forward the packet or reference to a next subsequent forwarding lookup.

摘要： According to one embodiment, the invention is directed to a facility for providing Asynchronous Transfer Mode (ATM) and Internet Protocol (IP) Quality of Service (QoS) features in a digital communication node. The facility includes a plurality of logical input ports, a plurality of logical output ports, ATM switching elements, IP routing elements and QoS elements. The switching and forwarding elements transfer ATM data cells and IP data packets from the logical input ports to the logical output ports. The QoS elements prioritize, schedule and flow control the transfer of data, based at least in part on ATM QoS features associated with the ATM data cells and on IP QoS features associated with the IP data packets.
