    摘要： A system includes a server including: logic adapted for receiving traffic from a virtual machine (VM), the traffic including at least one packet, logic adapted for hashing at least a portion of the at least one packet according to a hashing algorithm to obtain a hash value, and logic adapted for selecting an uplink based on the hash value; at least one accelerated network interface card (NIC), each accelerated NIC including: network ports including multiple Peripheral Component Interconnect express (PCIe) ports adapted for communicating with the server and a network, each network port including an uplink, logic adapted for encapsulating the at least one packet into an overlay-encapsulated packet, logic adapted for storing a media access control (MAC) address corresponding to the selected uplink as a source MAC (SMAC) address in an outer header of the overlay-encapsulated packet, and logic adapted for sending the overlay-encapsulated packet via the selected uplink.

    摘要： An example method is provided and includes a multicast data message from a data source, the message in a first virtual local area network and being associated with a multicast group. The method also includes calculating a hash value based on the virtual local area network, the data source, and the multicast group, determining a port for a designated router in a Layer-2 network based on the hash value, and switching the multicast data message to the port that was determined.

    摘要： Consistent with embodiments of the present disclosure, systems and methods are disclosed for providing per-group ECMP for multidestination traffic in a DCE/TRILL network. Embodiments enable per-group load balancing of multidestination traffic in DCE/L2MP networks by creating a new IS-IS PDU to convey the affinity of the parent node for a given multicast group. For broadcast and unknown unicast flooded traffic, the load balancing may be done on a per-vlan basis.
