TRANSMITTING MULTI-DESTINATION PACKETS IN OVERLAY NETWORKS

摘要

In an embodiment, a network adapter receives a request from a first virtual switch of an overlay network to transmit a multi-destination packet to each of one or more virtual switches of the overlay network identified in a list stored in the network adapter. For each of the one or more virtual switches identified in the list, the network adapter creates a head-end replication of the multi-destination packet, obtains tunneling endpoint information for the identified virtual switch, encapsulates the created head-end replication of the multi-destination packet with a header specific to a tunneling protocol identified in the obtained tunneling endpoint information, and transmits the encapsulated packet to a receiver hosted on the identified virtual switch.

1. A method comprising:
a network adapter receiving a request from a first virtual switch of an overlay network to transmit a multi-destination packet to each of one or more virtual switches of the overlay network identified in a list stored in the network adapter; and for each of the one or more virtual switches identified in the list:
the network adapter creating a head-end replication of the multi-destination packet;the network adapter obtaining tunneling endpoint information for the identified virtual switch;the network adapter encapsulating the created head-end replication of the multi-destination packet with a header specific to a tunneling protocol identified in the obtained tunneling endpoint information; andthe network adapter transmitting the encapsulated packet to a receiver hosted on the identified virtual switch.
