Abstract (en)
[origin: WO0163860A1] A method and device for traffic shaping is provided for multiple level or multi-layer shaping in parallel, which can also provide priority "shaping" to multiple data streams comprised of data packets. Data streams transmitted over connections or groups of connections comprised of a common channel or interface are "shaped" in order to control the data transfer rate allowed each user or group of users to be within a subscription rate. The traffic shaper uses software configured to provide logical circular queues to confirm, without a search, when data packets are conformant with a provisioned bandwidth. The traffic shaper also schedules the provisioned bandwidth to a logical link and thereafter to an output port. The traffic shaper also allows for transmission of bursts of data packets as permitted by a subscription schedule. Shaping is also possible to control data packet transmission to be within different bandwidths (i.e., a total rate and a sub-rate) and at multiple levels or layers to enable the shaping of, for example, oversubscribed bandwidth provided to groups of users.
