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.

A network device may act as a proxy for a client requesting video from a server and may control the quality of the video requested from the server. The network device may detect a negotiation for a video stream, the negotiation including at least a first message from the client indicating a requested video quality by the client; and determine a maximum allowed video quality for the client. The network device may additionally determine whether the requested video quality by the client is greater than the maximum allowed video quality and modifying, when the requested video quality by the client is greater than the maximum allowed video quality, a first message to change the requested video quality to be equal to the maximum allowed video quality.

A method may include receiving a packet at an ingress line interface in a forwarding plane of a network element, the packet including header information. The method may also include conducting a flow table lookup in the forwarding plane to identify an existing flow for the packet and determining, in the forwarding plane and based on the header information, whether a predicted flow can be identified for the packet if an existing flow can not be identified. The method may further include performing a service access control list (ACL) lookup in the forwarding plane if a predicted flow can not be identified; and forwarding the packet to one of a services plane or an egress line interface in the forwarding plane based on one of the existing flow, the predicted flow, or the service ACL lookup.

A VLAN tagging unit associated with a WAN is used to add VLAN tags based upon logical interfaces. In one example, data received across the logical interface is tagged with an associated VLAN ID by the unit. In another embodiment, flow-based VLAN tagging is done in which in addition to the logical interface other indications are used in the VLAN tagging.
