Abstract:

Systems and methods of offloading multicast virtual network packet processing to a network interface card are provided. In an example implementation, a network interface card can route packets in a virtual network. The network interface card can be configured to receive a data packet having a multicast header for transmission to a plurality of destination virtual machines. The network interface card can retrieve a list of next hop destinations for the data packet. The network interface card can replicate the packet for each next hop destination. The network interface card can encapsulate each replicated packet with a unicast header that includes a next hop destination virtual IP address indicating the next hop destination and a source virtual IP address, and transmit the encapsulated packets.

International Classification:

US Classification:

370235

Abstract:

A method and high availability cluster configuration for capture of data packets propagating in an external network into the cluster through a wired-tap connection between the cluster and at least one router of the external network. Captured packets are supplied with popularity tags and striped over high-access-rate non-transitory storage media belonging to a capture pool of serving nodes that are specially provisioned and selected by the master node. The captured packets are either devolved or demoted to low-access-rate non-transitory storage media of at least two serving nodes not including any backup master based on popularity metrics contained their tags. The demotion, devolution as well as determination of popularity metrics and setting of a popularity threshold are managed by a distributed management protocol.
