Filtering and route lookup in a switching device

摘要

Methods and devices for processing packets are provided. The processing device may Include an input interface for receiving data units containing header information of respective packets; a first module configurable to perform packet filtering based on the received data units; a second module configurable to perform traffic analysis based on the received data units; a third module configurable to perform load balancing based on the received data units; and a fourth module configurable to perform route lookups based on the received data units.

1. A method comprising:
determining, by a device, a data transfer rate per unit time interval associated with a flow of data; determining, by the device, a first time,
the first time being associated with receiving a first data unit included in the flow of data; determining, by the device and based on the data transfer rate per unit time interval, a quantity of data associated with the flow of data between the first time and a second time,
the second time being associated with receiving a second data unit included in the flow of data; and policing, by the device, the second data unit based on the quantity of data associated with the flow of data between the first time and the second time.
