摘要： RPR traffic management concepts are extended to individual client flows while adhering to the station level traffic management functions by using a two tiered shaper approach. The first tier manages the client level SLAs and feeds the second tier which provides the aggregate station level traffic management functions. This approach allows sharing of a single RPR station without the compromises and side affects associated with the other techniques. Apparatus for Resilient Packet Ring traffic management comprises a stage queue selection block operable to hold client and control traffic for transmission, a queue level traffic shaper operable to control an add rate of client data add traffic and to provide queue specific send indications to the stage queue selection block, and a ringlet level traffic shaper operable to control traffic flow for a Resilient Packet Ring ringlet and to provide aggregate send indications to the stage queue selection block.

摘要： A method of optimizing bandwidth usage in a link aggregated network includes identifying available bandwidth on a plurality of data links in a link aggregation group, selecting the data link with the least available bandwidth, and determining whether the available bandwidth of the selected data link is less than a guaranteed bandwidth of an incoming data flow. If the available bandwidth of the selected data link is less than the guaranteed bandwidth of the incoming data flow, the method includes selecting the data link with the next least available bandwidth and repeating the previous steps until the available bandwidth of the selected data link is greater than the guaranteed bandwidth of the incoming data flow. The method further includes assigning the data flow to the data link determined to have an available bandwidth greater than the guaranteed bandwidth of the incoming data flow.
