Transmitting sampled flows in datagrams to a collector includes adding entropy to the headers of the UDP packets that encapsulate the datagrams. The entropy, for example, can be a timestamp associated with a sampled data packet contained in the datagram. Each UDP packet is transmitted on a data patch selected from among a plurality of data paths using at least the UDP header. The entropy in each UDP header serves to spread the transmission of UDP packets across the plurality of data paths.

Adding entropy to datagrams containing sampled flows

Methods and systems for per-input port, per-control plane network data traffic class control plane policing in a network element are described. In one embodiment, the method comprises receiving control plane network data at an input port of a network element, wherein the control plane network data is data that is processed by the control plane. The method may also include classifying the control plane network data based on characteristics of the control plane network data. Furthermore, the method may include storing the control plane network data in one of a plurality of output queues for the input port based on a class of the control plane network data, and forwarding control plane network data from a selected one of the plurality of output queues to a control plane of the network element.
