Abstract: Embodiments generally provide techniques for load balancing data transmitted between line cards across a network fabric. Embodiments receive, at a first line card within a modular Ethernet switch, data to be transmitted to a second line card within the modular Ethernet switch. A mask table is accessed using a value corresponding to the second line card as an index in order to retrieve a mask value. Embodiments select one of a plurality of links for the first line card for use in transmitting the data, based on a load balancing algorithm and the retrieved mask value. The data is then transmitted to the second line card using the selected link.

Abstract: Presented herein are techniques to conserve power by network devices in a software define wide area network (SDWAN). A method includes monitoring operations of a software defined wide area network including a network device in the software defined wide area network, based on results of the monitoring, generating a usage model for the network device, determining, based on the usage model, a power management scheme for a multi-core network processing unit operating on the network device, and causing the multi-core network processing unit operating on the network device to execute the power management scheme.
