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： One embodiment disclosed relates to a method of mirroring network traffic. A data packet is received by a network device, and an algorithm including randomization is applied to determine whether the data packet is selected to be mirrored. The packet is sent to a destination port, and if the data packet is selected to be mirrored, then the packet is also sent to a mirror port. Another embodiment of the invention relates to a networking device. The networking device includes at least a plurality of ports, a switching/routing engine, and a mirroring engine. The plurality of ports receive and transmit packets therefrom, and the switching/routing engine is coupled to the ports for transferring the packets therebetween. The mirroring engine is configured to apply an algorithm including randomization to select data packets for mirroring. Other embodiments are also disclosed.

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： Methods of balancing network packet traffic among multiple checking functionalities (CFs) are described. A network has at least one client operatively connected to at least one source switch and multiple available CFs operatively connected to at least one destination switch. Each available CF has predetermined, but possibly different inspection capabilities. A source switch receiving packets from a client inspects each packet and can optionally choose an available CF having at least the minimum necessary inspection capabilities to inspect the particular packet, and tunnel the packet to the chosen CF.
