摘要： A system for regulating traffic in a computer network comprises a plurality of rate buckets associated with a network interface ingress port. The system includes at least two rate buckets, related hierarchically, assigned to a specific ingress port on a network equipment device. At least one traffic parameter is associated with each rate bucket. Each rate bucket monitors traffic based on individual user-defined traffic parameters. At least one packet threshold parameter is associated with each rate bucket. Packets exceeding a rate bucket's packet threshold parameter are sent to subsequent rate buckets within the hierarchy based on an aggregate information rate assigned to the port. Each hierarchical rate bucket assigned to a specific port evaluates each packet prior to discarding a packet.

摘要： A network device configured to i) control a rate of traffic while operating in a rate-limiting mode, and ii) mirror traffic while operating a sampling mode. The network device includes an ingress circuit configured to receive packets, and a rate limiter in communication with the ingress circuit. The rate limiter is configured to, while the network device is operating in the rate-limiting mode, perform a rate-limiting scheme to control a rate of the packets received through the ingress circuit. The rate limiter is further configured to, while the network device is operating in the sampling mode, perform a modified form of the rate-limiting scheme to mirror the packets received through the ingress circuit.
