Abstract: In general, techniques are described for scheduling traffic for delivery over an aggregated bundle of links. A network device comprising an interface and a data plane may implement the techniques. The interface receives packets associated with packet flows. The data plane associates each of the packet flows with a different link of an aggregated bundle of links. The data plane monitors transmission of the packets via the links to determine a representation of an amount of data sent per link. The data plane further determines that bandwidth utilization does not conform to a desired bandwidth utilization based on the determined representation of the amount of data sent per link. The data plane then re-associates the packet flows to different links of the aggregated bundle based on the determination that the bandwidth utilization does not conform to the desired bandwidth utilization.

Abstract: In general, techniques are described for performing packet loss measurement in a distributed data plane. In one example, a local router includes a plurality of forwarding units that implement a distributed data plane. First and second forwarding units may switch layer two (L2) packet data units (PDUs) between the local router and a remote router using a virtual path. The first and second forwarding may unit may increment, in response to processing any PDU of the PDUs for the virtual path, respective counters stored by the first and second forwarding units. The first and second forwarding units may update, based on the respective counters, a loss-measurement packet (LMP). For instance, the first forwarding unit, upon updating the LMP, may internally forward the LMP to the second forwarding unit. The second forwarding unit, upon updating the LMP, may send the LMP to the remote router.
