摘要： Methods for controlling a Designated Forwarder (DF) election in a multicast network are described herein. The multicast network includes a plurality of multicast network devices, including a first network device and a second network device. A Designated Forwarder is determined. It is determined whether to initiate a Designated Forwarder election based on a comparison of a metric measuring a distance to a Rendezvous Point Address from a first network device and a metric measuring the distance to the Rendezvous Point Address from the second network device.

摘要： A method for sliding window processing of a datagram split into packets, may include processing entire strings of adjacent consecutive packets of the datagram regardless the order of the packets using parallel processors. The method may also include processing adjacent ends of the strings of the adjacent consecutive packets while maintaining the order of the adjacent ends to correspond to the order of the consecutive packets.

摘要： Techniques are provided for sending response messages based on pending requests. A request message identifying a data packet may be received. A pending request structure may be used to determine output queues that are in need of the data packet identified in the request message. A response message may be sent indicating if the request message is being refused based on the output queues.

摘要： A method for checking expected network traffic is disclosed. The method for checking expected network traffic includes accessing pre-registered expected results of a network traffic checking exercise that include expected packet content verification information for individual packets of the network traffic. In addition, the method includes accessing network traffic where individual packets of the network traffic include actual packet content verification information. Individual packets are identified that have expected packet content verification information that does not match their actual packet content verification information and individual packets are identified that have expected packet content verification information that does match their actual packet content verification information.

摘要： As described herein, a node may include storage to store a cost for each of a number of paths, where a path connects two nodes in a system. A path may be determined between the node and a destination node based on execution of a shortest path first algorithm, the shortest path first algorithm to determine if a cost between two nodes is stored in storage prior to communication with another node to determine cost.

摘要： One embodiment disclosed relates to a method of sampling network traffic. A data packet is received by a network device. Information is extracted from fields in the data packet, and a look-up word is created using the extracted information. A content addressable memory is searched for entries matching the look-up word. If a match is found, then a sampling circuit is queried, and a response is received therefrom. The data packet may be sent to a destination port. In addition, if the response from the sampling circuit indicates that the data packet is chosen to be mirrored, then the data packet may be also sent to a mirror port. Other embodiments are also disclosed.

The forward counter block may also include an update engine, the update engine configured to update an external memory by forwarding a value stored in any of said at lease one of a plurality of local counter storage elements and return a zero value to that local counter storage element, when the value stored in that local counter storage element reaches or surpasses a threshold value.
